Cities & Infrastructure · Urban Water Infrastructure
Deliver safe, reliable and affordable urban water from source to tap while protecting aquifers, ecosystems and future supply.
This page turns the subject into a public problem-solving framework: place, problem, causes, evidence, solutions, roadmap, results and contribution.
Problem
What is failing, for whom and where?
02 · Households depend on tankers or storage despite formal connections.
03 · Source depletion, contamination and unequal access remain hidden by city averages.
Root causes
Test causes before selecting projects.
Source planning is separated from land and ecosystem management
Verify this mechanism against local institutions, assets, user experience and available evidence.
Networks lack pressure zones and reliable asset data
Verify this mechanism against local institutions, assets, user experience and available evidence.
Intermittent supply increases contamination risk
Verify this mechanism against local institutions, assets, user experience and available evidence.
Metering and billing do not reflect service quality
Verify this mechanism against local institutions, assets, user experience and available evidence.
Informal settlements have weak legal access
Verify this mechanism against local institutions, assets, user experience and available evidence.
Wastewater reuse and demand management lag
Verify this mechanism against local institutions, assets, user experience and available evidence.
Evidence
Record what is known, how it is known and what remains uncertain.
| Evidence area | What to establish | Key limitation |
|---|---|---|
| Source | Yield, quality, seasonality and ecological limit | Licensed capacity may exceed sustainable supply |
| Network | Pipe, pressure, leakage, outage and repair | Estimated losses need measurement |
| Quality | Source, treatment, network and household sampling | Compliance averages hide local events |
| Access | Hours, distance, price and household storage | Connection status is insufficient |
| Demand | Use by household, institution and industry | Meter gaps create uncertainty |
Evidence rule: label verified evidence, partial evidence, illustrative analysis, community submission and insufficient evidence separately.

Risks & safeguards
Address foreseeable harm before scaling.
Supply-side lock-in
New sources delay efficiency and leakage repair
Safeguard: Compare full lifecycle alternativesAffordability harm
Tariff reform burdens vulnerable users
Safeguard: Protect essential use and publish service standardsContamination
Pressure loss draws pollutants into pipes
Safeguard: Improve continuity, monitoring and rapid responseSource conflict
City withdrawal harms rural users or ecosystems
Safeguard: Basin-level allocation and safeguardsFAQ
Questions that should be answered before action.
No. Reliability, quality, affordability and quantity must also be measured.
It requires network condition, pressure management, source balance and phased verification.
Water produced but not billed because of physical loss, meter error, unauthorised use or record problems.
