Urban Water Utilities in Africa: Reducing Non-Revenue Water to Finance Reliable Service

EXECUTIVE THESIS

Africa's water-investment debate is too often organised around new supply. Governments and development partners count reservoirs, treatment plants, boreholes, trunk mains and finance commitments. Yet a utility cannot invest its way out of operational failure if a large share of treated water never becomes a reliable, billed service.

The African Union made sustainable water availability and safe sanitation its theme for 2026. In July, the N'Djamena Declaration placed water security at the centre of economic transformation and called for stronger institutions, public and private finance, and regional cooperation.[1][2] The United Nations Water Conference in December will bring another round of pledges.[3] The practical question is what kind of institution can convert those commitments into service.

Non-revenue water, or NRW, is the difference between water entering a distribution system and water for which the utility receives revenue. It includes physical losses from leaks and bursts, and apparent losses from meter error, unauthorised consumption and weak data or billing. It is not a perfect measure: some authorised uses are unbilled, and a low percentage can conceal poor supply or underinvestment. But high NRW is a revealing systems indicator because it connects engineering, commercial management, governance and customer trust.

In Kenya, the Water Services Regulatory Board's 2026 IMPACT 18 report recorded NRW rising from 44 to 48 per cent in 2024/25, even as water coverage in regulated service areas increased from 70 to 72 per cent and metering remained at 97 per cent.[4] The Ministry of Water estimated in May that losses around 44 per cent represented more than KSh10 billion a year that could otherwise support asset renewal, network expansion and sector finance.[5] The apparent contradiction matters: installing customer meters does not by itself create control over a network. Utilities also need bulk measurement, pressure management, accurate customer records, functioning billing, fast repair, legal enforcement, and management authority to act on the data.

Southern African evidence makes the financial link explicit. At a March 2026 World Bank programme, 18 water service providers from five countries all reported NRW above 45 per cent. Five utilities developed plans to reach an interim 35 per cent target. The World Bank estimated that this change could save 31 million cubic metres annually, enough to serve one million people, and generate US$57 million in annual financial savings.[6] These are programme estimates rather than audited realised outcomes, but they illustrate why leakage is not only an engineering concern. It is a recurring claim on energy, chemicals, staff time, revenue and public credibility.

Uganda offers a useful contrast rather than a perfect success story. The National Water and Sewerage Corporation reported reducing NRW from 36 to 34 per cent between 2021 and 2024 while expanding its customer base and asset base; its 2025-2030 strategic plan still identifies 33.7 per cent NRW as a significant operational and revenue constraint.[7][8] South Africa's 2026 Mpumalanga Municipal Utility Reform Programme combines loss reduction, metering, pipeline rehabilitation and pressure management with financial-sustainability reforms.[9] These cases point to a common conclusion: loss reduction lasts when it is embedded in a utility's governance, incentives, finance and maintenance routines, not run as a temporary leak-detection campaign.

STONECOMMS ORIGINAL SYNTHESIS Non-revenue water should be treated as an institutional stress test. A utility that can locate losses, assign responsibility, protect low-income access, verify results and reinvest savings is building the same operating capabilities that lenders, regulators and citizens need to trust. The investable asset is not the pipe alone. It is the utility's capacity to keep the pipe productive.

StoneComms proposes a five-part Water Value Recovery Chain: measure the system; diagnose physical and commercial losses; contract and manage reduction; convert verified savings into protected maintenance and service improvements; and disclose outcomes to customers, regulators and financiers. Each link has to work. Without measurement, contractors are paid for uncertain baselines. Without governance, savings disappear into general accounts. Without an affordability framework, stricter billing can punish households rather than improve service. Without reinvestment, losses rebound.

The principal recommendation is therefore selective and operational. African governments and development financiers should stop treating NRW reduction as an accessory component attached to expansion projects. For utilities with material losses, it should become an investable first phase: a time-bound programme with independently verified baselines, service and equity safeguards, clear responsibility for assets and data, and a legally protected route from savings to maintenance and expansion.

WHY THIS MATTERS NOW

Water policy is moving from scarcity language to delivery systems

The scale of unmet need is familiar but still consequential. The African Water Forum reported in July 2026 that more than 400 million people across Africa lacked basic drinking water and more than 700 million lacked basic sanitation.[2] The WHO/UNICEF Joint Monitoring Programme has also shown that progress is highly unequal: in 2020, three in five Africans lacked safely managed drinking water, while data gaps prevented complete assessment in many countries.[10] These service deficits sit beside rapid urban growth, climate stress and rising demand from households, commerce and industry.

The policy calendar creates a useful window. The African Union's 2026 theme places water and sanitation at the centre of development and climate resilience.[1] The African Water Facility's 2026-2030 strategy emphasises project preparation, innovative investment and governance.[11] Country Water Compacts are being developed under the Water Forward initiative, while the December UN Water Conference will test whether political commitments can become credible investment programmes.[2][3]

That conversion is difficult because urban water is not a conventional infrastructure asset. The public interest requires affordable, equitable access. Revenues are often politically constrained. Distribution networks are buried, old and imperfectly mapped. Customers may receive water intermittently, so pressure changes can damage pipes and contaminate supply. Municipal finances may not be ring-fenced. Climate shocks change both source availability and operating cost. A utility can therefore have a socially essential mandate without having a balance sheet that attracts commercial capital.

This is precisely why operational performance matters. A lender cannot rely on a tariff if the utility cannot measure volumes, collect bills, maintain assets or protect cash. A regulator cannot defend a tariff increase if customers see persistent bursts and intermittent service. A government cannot justify a new plant if half the additional production will disappear. Loss reduction creates no substitute for public finance, but it can improve the productivity and credibility of every subsequent unit of finance.

KEY FINDINGS

1. Non-revenue water is a compound institutional loss

Physical leaks waste raw water, treatment chemicals and pumping energy. Apparent losses erode billed revenue. Both consume staff time and weaken customer confidence. The same headline percentage can arise from very different causes, so an NRW programme must disaggregate real losses, apparent losses and authorised unbilled consumption before choosing investments.[12]

2. Measurement coverage is not measurement quality

Kenya's 97 per cent metering ratio alongside 48 per cent NRW shows why customer-meter installation is only one layer of control.[4] Utilities need reliable production meters, district-metered areas, pressure and night-flow information, calibrated customer meters, geospatial asset records, and reconciliation between operational and billing systems. A meter that is not read, calibrated or connected to a trustworthy customer record cannot create accountability.

3. Loss reduction can create a cash flow before expansion creates one

Where water is already produced, recovering saleable volume and reducing avoidable operating cost can generate benefits faster than building a new source. The Southern African plans estimated US$57 million a year in combined savings from a ten-percentage-point interim reduction among five utilities.[6] The economic case depends on local production cost, tariff, collection efficiency and the cost of intervention; not every leak is worth repairing immediately.

4. Creditworthiness follows governance as well as engineering

World Bank evidence links high NRW with weak utility creditworthiness and highlights the importance of ring-fenced finances.[6] Botswana's history of utility bond issuance and Eswatini Water Services Corporation's repeated commercial borrowing show that public ownership does not automatically exclude market finance. But creditworthiness requires predictable authority, transparent accounts, management discipline and credible regulation alongside physical performance.

5. Performance-based contracts can accelerate results, but baselines are the contract

NRW performance-based contracts pay for measured improvement and can bring specialist capability to constrained utilities.[12] They work only when the service area, baseline, measurement protocol, risk allocation, data ownership and payment formula are credible. A contractor cannot fairly accept performance risk for intermittent supply, unrecorded network changes or political interference it cannot control.

6. Affordability and revenue discipline must be designed together

Reducing unauthorised use and improving billing can increase revenue, but blunt enforcement can harm low-income households, tenants and informal settlements. Loss reduction must be paired with lifeline or social tariffs, legitimate shared connections, transparent complaint mechanisms, service-quality commitments and protection against arbitrary disconnection. The objective is paid, reliable service—not exclusion.

7. Savings are durable only when they finance maintenance

Leak repair without asset renewal can create a short-lived improvement. Utilities need a visible rule for allocating a portion of verified savings to preventive maintenance, meter replacement, pressure management and network rehabilitation. Otherwise the programme improves a ratio temporarily while the underlying asset base continues to deteriorate.

EVIDENCE AND METHOD

This is a comparative public-source study completed on 8 October 2026. The research question is: under what operational, governance and financing conditions can reducing non-revenue water improve reliable urban water service and the investability of African utilities?

The unit of analysis is the urban water-utility operating system, not an individual technology. Kenya provides the most current national regulatory evidence. Uganda offers an integrated public-corporation comparison. South Africa provides both provincial loss data and a current municipal reform programme. Southern African workshop estimates show how utilities are linking efficiency to creditworthiness. Senegal is used to examine contractual and financing architecture, including performance contracts and proposed innovative finance under its 2026 Water Compact.[6][7][9][13]

Sources include the African Union, United Nations, World Bank, African Development Bank, WHO/UNICEF JMP, national regulators, water ministries and public utilities. Quantitative claims are kept in their reported units. Programme estimates are identified as estimates; country and utility indicators are not treated as directly comparable where definitions, reporting years, service continuity or data quality differ.

No proprietary utility accounts, network telemetry, contract documents, engineering condition surveys, customer interviews or household affordability microdata were available. The paper does not estimate a continent-wide value of recoverable water, because applying one loss rate, tariff or production cost across heterogeneous utilities would create false precision.

1. MEASURE THE SYSTEM BEFORE BUYING THE SOLUTION

The denominator can mislead as easily as the percentage

NRW is normally expressed as a percentage of system input volume. That makes it intuitive but incomplete. A utility supplying continuously at high pressure may report a similar percentage to one providing intermittent service, even though leakage dynamics and customer experience differ. A rapidly growing utility may reduce absolute losses while the percentage barely moves; another may lower the percentage by reducing supply rather than repairing assets.

The first investment should therefore be a defensible water balance. Production meters need calibration. Network boundaries need to be known. Authorised unbilled uses—such as firefighting or public standpipes—must be recorded. Customer databases should link accounts to physical connections. Billing data need reconciliation with operational volumes. Physical and apparent losses should be estimated separately.[12]

Kenya's recent experience is instructive. IMPACT 18 reports that regulated water coverage rose to 72 per cent and drinking-water quality to 96 per cent, while NRW increased to 48 per cent and metering remained at 97 per cent.[4] These figures do not prove that meters are ineffective. They show that one performance indicator cannot substitute for system diagnosis. A high metering ratio can coexist with inaccurate meters, missing bulk data, poor reading, illegal connections, intermittent supply and leakage between production and the customer boundary.

A serious NRW programme divides the network into manageable zones. District meters and pressure loggers establish how much water enters each area. Minimum night flow can help identify continuous leakage where supply is stable. Customer and billing audits identify apparent losses. Repair teams need response targets and stocked materials. Managers need a daily or weekly view of exceptions rather than an annual national average.

Digital tools can help, but the sequence matters. Smart meters on an unmapped network create more data without necessarily creating control. Artificial intelligence cannot repair a burst, correct a customer record or adjudicate a disputed bill. The operational question is always: what decision will this measurement trigger, who is authorised to act, and how will the result be verified?

2. VALUE THE RECOVERED WATER, NOT THE ANNOUNCED TECHNOLOGY

The economic level of leakage is local

No utility should pursue zero NRW. Some water is used legitimately without revenue, some meter error is unavoidable, and the marginal cost of eliminating every leak can exceed the value recovered. The investable question is the economic level of leakage: the point at which the cost of further reduction is approximately equal to the value of water and revenue saved, adjusted for reliability, scarcity and social benefit.

That value differs sharply. Where water is pumped long distances, desalinated or treated intensively, physical losses carry high energy and chemical costs. Where the source is constrained, recovered water may defer an expensive supply project. In a low-cost gravity system, commercial losses may matter more than leakage. In an intermittently supplied city, pressure management and continuity may create health and service benefits beyond billed volume.

The Southern African utility plans provide a useful order of magnitude but not a universal ratio. Five utilities moving towards 35 per cent NRW estimated 31 million cubic metres in annual savings and US$57 million in financial benefit.[6] The implied value reflects those utilities' assumptions about production, tariffs, collection and intervention; it should not be extrapolated across Africa. Its real significance is institutional: the utilities connected an engineering target to a financial case and a service outcome.

Kenya's Ministry of Water made the same connection in May 2026 when it estimated more than KSh10 billion in annual losses at an NRW level of about 44 per cent and identified asset renewal, pipeline expansion and sector financing as alternative uses for that value.[5] IMPACT 18 subsequently reported 48 per cent.[4] The policy lesson is not simply to spend on leak detection. It is to establish a national reduction programme that requires utilities to show where a recoverable cubic metre creates the highest combined financial and service value.

3. CONTRACT FOR RESULTS WITHOUT OUTSOURCING ACCOUNTABILITY

Performance-based contracts are a governance tool

Traditional works contracts pay a supplier to install specified equipment or repair a stated length of pipe. Performance-based NRW contracts pay for a measured outcome, such as a reduction in losses or an increase in billed volume within a defined zone. This can give contractors flexibility to combine diagnostics, repairs, pressure management, meter work and data correction.[12]

The attraction is obvious where utilities lack specialist skills or working capital. The danger is equally clear. If the baseline is weak, the contractor and utility can dispute whether improvement is real. If water pressure, supply hours or customer numbers change, the headline loss percentage may move for reasons unrelated to contractor performance. If the utility does not control road permits, procurement lead times, electricity supply or political enforcement, risk can be allocated to the wrong party.

A credible contract needs six elements: a jointly verified baseline; a defined service area and asset boundary; performance indicators that cover water, service and customer outcomes; rules for external changes; independent verification; and a handback plan for data, equipment and capability. Payment should reward verified improvement without encouraging disconnection, under-supply or selective attention to easy zones.

The public authority remains accountable. It must protect customer rights, approve tariffs, regulate quality, ensure environmental compliance and plan long-term assets. Private expertise can accelerate delivery; it cannot replace the legitimacy and stewardship functions of the utility and regulator.

4. CONNECT OPERATIONAL PERFORMANCE TO FINANCE

Creditworthiness is an operating outcome

Water utilities often approach finance as though the principal task were finding a lender willing to accept sector risk. The more durable route is to change the evidence available to the lender. Audited accounts, ring-fenced cash flows, transparent tariffs, collection discipline, asset registers and measured NRW create a record of management performance.

The World Bank's 2026 Southern African programme explicitly joined WaterCred assessments with NRW planning. All 18 participating utilities had losses above 45 per cent, and the programme's central lesson was that operational efficiency underpins financial credibility.[6] Eswatini Water Services Corporation was cited as having accessed commercial finance four times; Botswana was noted for public-utility bond issuance. These examples do not mean every utility should borrow. They show that public-service institutions can earn access to longer-term capital when governance and performance support repayment.

Uganda's NWSC illustrates gradual institutional accumulation. Its 2023/24 annual report describes growth in assets and customers alongside a reduction in NRW from 36 to 34 per cent over the 2021-2024 corporate-plan period.[7] Its subsequent strategic plan still identifies 33.7 per cent NRW as a significant constraint.[8] Performance is therefore not a graduation certificate. It is a continuing management obligation, especially as networks expand and old assets remain in service.

South Africa's Mpumalanga Municipal Utility Reform Programme similarly combines operational and financial reform. The African Development Bank's 2026 appraisal links NRW reduction, customer metering, pipeline rehabilitation and pressure management to greater efficiency and financial sustainability in municipal water and electricity services.[9] This integrated design is important because technical savings cannot strengthen credit if municipal accounts obscure the revenue or if collections are not retained for the service.

5. PROTECT AFFORDABILITY AND CUSTOMER LEGITIMACY

A utility cannot become bankable by making poor households invisible

The language of revenue recovery can create a false choice between financial discipline and social access. A utility that cannot cover reasonable operating and maintenance costs will eventually ration service through breakdown, intermittent supply or stalled expansion. But a utility that pursues collections without affordability safeguards can exclude the people public infrastructure exists to serve.

The solution is explicit cross-subsidy and service design. Social or lifeline tariffs should be transparent and funded. Informal settlements may need legal shared connections, pre-agreed kiosks or delegated management rather than blanket classification as illegal consumption. Tenants need protection when landlords control accounts. Complaint and correction processes must work before stricter billing is introduced. Service standards—hours, pressure, quality and response time—should be published alongside collection targets.

Senegal's long-running urban water reforms show the potential of performance contracts when public objectives remain visible. World Bank documentation describes extending performance accountability to sector institutions and linking operator incentives to service outcomes.[13] The 2026 Senegal Water Compact identifies possible climate finance, blue bonds and sanitation-linked cash flows, but financing credibility will depend on the same fundamentals: defined revenue, accountable institutions, service performance and public protection.[14]

The strongest political bargain is reciprocal. Customers are asked to pay according to a fair tariff and legitimate connection; the utility is required to provide a known level of service, fix faults, explain bills and disclose how recovered value is used.

STONECOMMS ORIGINAL SYNTHESIS

The Water Value Recovery Chain

The evidence suggests that NRW reduction should be designed as a five-link institutional chain rather than a collection of repairs.

1. Measure. Establish a verified water balance, network zones, production volumes, service continuity, customer records and an explicit confidence rating for the baseline.

2. Diagnose. Separate physical leakage, meter error, unauthorised use, data weakness and authorised unbilled consumption. Rank zones and interventions by financial, service and scarcity value.

3. Deliver. Match the delivery model to the problem: utility teams, framework contracts, targeted capital works or performance-based contracting. Allocate only controllable risks and protect customers.

4. Reinvest. Route a disclosed share of verified savings into preventive maintenance, asset renewal, low-income connections and continuity improvements. Do not allow recovered value to disappear into an unrelated municipal deficit.

5. Prove. Publish independent results covering absolute and percentage losses, service hours, water quality, customer complaints, collection, affordability and use of savings.

The analytical bridge is straightforward. Kenya shows that metering and coverage can improve while NRW worsens.[4] Southern African utility plans show that defined reduction can be translated into water and financial value.[6] Uganda shows that improvement is incremental and reversible.[7][8] South Africa shows why operational and financial reforms need to be designed together.[9] Senegal shows how performance contracts and finance architecture can be connected.[13][14]

The hypothesis requiring further research is whether a verified chain can reduce the cost of capital or expand lender participation after controlling for sovereign support, tariff policy and utility size. Existing public evidence supports an association between efficiency and creditworthiness, not a universal causal coefficient.[6]

PAN-AFRICAN COMPARISON AND SCALABILITY TEST

One framework, different binding constraints

Kenya: The immediate constraint is not absence of national reporting. It is translating strong regulatory visibility into local network control and sustained reduction. National NRW rose to 48 per cent in 2024/25 despite 97 per cent metering.[4] A scalable programme needs verified district baselines, utility-specific targets and finance linked to actual loss drivers.

Uganda: NWSC's integrated national-corporation model provides stronger organisational coherence than fragmented municipal systems, but 33.7 per cent NRW still represents material lost value.[8] The scalability question is how performance management holds as the customer and asset base grows.

South Africa: Municipal autonomy and financial fragmentation make ring-fencing and governance central. National data show wide provincial variation, while Mpumalanga's programme combines network and institutional reforms.[9][15] The scalable unit may be a provincial reform platform supporting multiple municipalities rather than a single national contract.

Senegal: Performance contracting and a clearer division of institutional roles offer a basis for innovative finance, but water scarcity and major supply investment around Dakar mean demand management cannot replace new source development.[13][14] The test is whether operating efficiency, social policy and capital expansion remain aligned.

Fragile and secondary cities: Utilities may lack complete networks, reliable power, audited accounts or enough billed customers to support a conventional PBC. Here, grants and concessional finance remain essential. The chain still applies, but the first investable output may be an asset register, bulk-metering plan and maintenance system rather than a commercial loan.

Scalability therefore lies in common disciplines, not one contract form. Baseline verification, transparent loss categories, customer safeguards, reinvestment rules and public reporting can travel. Tariffs, ownership, procurement, climate exposure and delivery models must remain local.

IMPLICATIONS FOR POLICY, CAPITAL AND IMPLEMENTATION

Governments

Make NRW and continuity part of national infrastructure strategy, not only utility management. Require utilities seeking major expansion finance to publish a water balance, asset-maintenance plan and loss-reduction pathway. Establish rules for ring-fencing service revenue and verified savings where municipal structures allow.

Regulators

Report both percentage and absolute loss, data confidence, supply hours, water quality, affordability and complaint resolution. Avoid rewarding a lower ratio achieved through reduced production or exclusion. Use comparative reporting to identify peer utilities and transfer practice, while recognising structural differences.

Development finance institutions

Finance diagnostics and operational reform as a first-class infrastructure investment. Structure phased facilities in which early disbursement supports measurement, governance and high-return repairs; later capital supports expansion once performance evidence is established. Do not require commercial borrowing where grants or concessional finance are more appropriate.

Utilities

Create a joint engineering-commercial NRW unit with executive authority. Reconcile network and billing data, prioritise zones, publish repair response times, and protect institutional knowledge when contractors leave. Treat customer legitimacy as an operating asset.

Private contractors and technology firms

Sell verifiable outcomes rather than devices. Accept performance risk only where baselines and operating responsibilities are clear. Build local repair capability and data handover into delivery. Avoid proprietary platforms that make the utility dependent on one vendor for basic network intelligence.

Investors

Read loss reduction as evidence, not collateral. Examine tariff authority, collection, cash ring-fencing, asset condition, governance and sovereign support alongside NRW. Ask whether savings have been realised and retained, and whether service quality improved.

RISKS, COUNTERARGUMENTS AND LIMITATIONS

Counterargument 1: Africa needs more water, not better ratios

Many cities do need new sources, storage and treatment. Loss reduction cannot create water where hydrological supply is insufficient, and demand growth can exceed recoverable volume. Response: the choice is rarely either/or. Recovering value can defer part of expansion, improve use of new capacity and strengthen the institution that will operate it.

Counterargument 2: tariffs, not leakage, determine financeability

Tariffs are critical. A utility with efficient operations but a tariff far below reasonable cost cannot remain financially sustainable. Response: tariff reform without visible efficiency is politically fragile. Loss reduction creates evidence that the utility is controlling costs and improving service; affordability policy determines how cost recovery is distributed.

Counterargument 3: performance-based contracting is privatisation by stealth

A PBC can transfer specific delivery tasks and risks to a private contractor, but ownership, regulation, tariff authority and public accountability can remain public. Response: contracts must disclose scope and performance, retain data ownership, protect workers and customers, and include handback of capability. Where those safeguards are absent, scepticism is justified.

Counterargument 4: the data are too weak for results-based finance

In some utilities, they are. Response: that is a reason to make baseline construction an initial funded phase, not to invent precision. Payments can begin with verified milestones—calibrated bulk meters, mapped zones, reconciled customers—before outcome payments are introduced.

Evidence limitations

Public NRW figures differ in method, period and quality. Utility self-reports may be revised. The World Bank's five-utility savings are planned estimates, not completed audited benefits.[6] Kenya's national averages conceal substantial variation among providers.[4] Uganda's corporate figures do not by themselves prove customer-level reliability or affordability.[7] South African provincial data do not establish causation between governance and losses.[15]

This paper does not quantify health benefits, greenhouse-gas reductions, energy savings or avoided capital expenditure. Those outcomes may be material but require local operating data. It also does not advise any investor to lend to a utility or any government to adopt a specific contract without legal, financial, environmental and social diligence.

COMMISSIONABLE RESEARCH AGENDA

A 20-utility Water Value Recovery Observatory

A serious next commission should test whether the proposed chain predicts service and financial improvement across different institutional models. The programme could follow 20 utilities in at least eight countries for 24 months.

Workstream 1: common measurement. Build comparable water balances, confidence scores, supply-continuity records, pressure zones, customer registries and loss categories.

Workstream 2: household experience. Survey low-income and formal customers on hours, quality, coping costs, billing disputes, connection status and willingness to pay for defined service improvements.

Workstream 3: asset economics. Model marginal abatement cost for physical and apparent losses, including energy, chemicals, repair, meter renewal and avoided supply investment.

Workstream 4: governance and finance. Compare tariff authority, ring-fencing, collection, audit quality, procurement, political oversight and borrowing terms. Test whether verified performance changes lender appetite or pricing.

Workstream 5: contract evaluation. Compare in-house programmes, conventional works, service contracts and PBCs using pre-agreed counterfactuals where feasible.

Workstream 6: public accountability. Produce regulator-ready dashboards showing absolute and percentage loss, data confidence, service, affordability and reinvestment.

The resulting evidence would help governments distinguish utilities that need basic institutional rebuilding from those ready for results-based contracts or commercial finance. It would also create a defensible pipeline of projects where recovered value can be linked to measurable service improvement.

CONCLUSION

Africa's urban water problem is not only that too little infrastructure has been built. It is that too much existing infrastructure is allowed to lose water, money and trust before it produces dependable service.

The current policy moment is unusually favourable. Water is the African Union's theme for 2026. Country compacts and an African declaration are linking water to economic transformation. Development institutions are preparing more projects and looking for public-private finance. The danger is that new money flows into new assets without strengthening the utilities that must operate them.

Non-revenue water offers a disciplined place to begin because it makes institutional capability visible. Can the utility measure its system? Can it distinguish a leak from a billing failure? Can it contract and supervise work? Can it protect poor households? Can it retain savings for maintenance? Can it prove what changed?

Where the answer becomes yes, the benefit is larger than recovered cubic metres. The utility begins to look like a credible steward of public assets and a trustworthy counterparty for customers, regulators and capital. Where the answer remains no, another treatment plant may increase capacity without increasing reliable service.

The investment case is therefore not simply to fix leaks. It is to build institutions that keep water, money and accountability in the same system.
