The Global Centre for Risk and Innovation (GCRI)
Urban utilities deliver water, sanitation, drainage, solid waste collection and energy to homes and businesses. Their reach and reliability decide public health, flood risk and the cost of living in a city, and gaps fall hardest on the poorest neighbourhoods. This page sets out how urban utility services expand, fail and recover, how coverage and quality are measured, and what evidence serves the utilities and city authorities responsible.

Urban water, sanitation and waste services are the utilities that supply drinking water, remove and treat sewage, drain stormwater and collect solid waste in cities. Their reach and reliability shape public health and flood risk, gaps fall hardest on poor neighbourhoods, and the services depend on each other and on electricity.
For urban utilities, in GCRI's spatial-intelligence reading, the map opens on night lights, population density and true-colour imagery with relief in 3D and true colour from NASA GIBS, framed on India; 3 further NASA layers wait in the list.

Water, waste, electricity and communications. The dossier below sets out how the risk develops, what is measured, where the data come from, how it is modelled and who decides.
Pipes, sewers and lines follow formal development and ability to pay. New and informal areas are served by tankers, vendors, pit latrines and illegal connections, at higher cost and risk.
Uncollected solid waste blocks drains and channels, turning ordinary rain into local floods. Waste collection is a flood control service as well as a sanitation service.
Utilities that cannot recover costs underinvest in maintenance and expansion. Subsidies often benefit connected, better-off households more than the unconnected poor.
Water and wastewater need electricity; drainage needs waste collection; energy systems need water for cooling. A failure in one service degrades others.
Each term as this page uses it. Where a standard-setting body defines the term, the wording follows that body.
| Term | Definition |
|---|---|
| Safely managed sanitation | Use of improved facilities not shared with other households, where excreta are safely disposed of or treated. |
| Faecal sludge management | The collection, transport and treatment of waste from on-site sanitation such as pit latrines and septic tanks. |
| Municipal solid waste | Waste from households and similar sources collected by or for municipalities. |
Each indicator carries its unit, its cadence, the kind of source behind it and the evidence label a value would carry. No values are shown: a programme supplies them under its own authority.
| Indicator | Unit | Cadence | Source type | Label |
|---|---|---|---|---|
| Population with safely managed drinking water | percent of urban population | annual | WHO/UNICEF Joint Monitoring Programme | ESTIMATED |
| Population with safely managed sanitation | percent of urban population | annual | WHO/UNICEF Joint Monitoring Programme | ESTIMATED |
| Municipal solid waste collected | percent of waste generated | annual | SDG indicator 11.6.1 data | REPORTED |
| Hours of water supply | hours per day | monthly | Utility service records | REPORTED |
| Population with access to electricity | percent of urban population | annual | Tracking SDG 7 | ESTIMATED |
| Local flood events linked to blocked drains | count | annual | Municipal records | REPORTED |
The topic as a computational graph: named sources feed the methods, an evidence review gates the outputs, and the decisions stay with the authorities that hold them.

Coverage, reliability, quality and affordability of each service across neighbourhoods.
Which failures in one service stop another, and how quickly.
Flooding of substations and treatment works, heat stress on networks, drought limits on supply.
Backup power, storage, redundancy, mutual aid and restoration priorities.
Utility networks share space and dependencies. Water pumping and treatment, wastewater lifting and telecommunications all need electricity; electricity generation often needs cooling water; control systems need communications. A long outage therefore spreads from one service to all.
Ageing assets and underinvestment raise everyday failure rates, which reduces the capacity to absorb hazards. Leakage, intermittent supply and blocked drains are chronic in many cities.
Solid waste is often overlooked. Uncollected waste blocks drains, worsening floods, and burns or decomposes into health hazards.
Digitalization adds a new layer. Smart meters, remote control and shared cloud services improve efficiency but create common points of failure and cyber exposure across services that once failed separately. Restoration also competes for the same crews, fuel and spare parts, so priorities set in advance matter.
| Method or data | What it shows | Its limit |
|---|---|---|
| Utility performance data | Coverage, outages and quality | Often confidential or inconsistent |
| Asset and network maps | Location and connection of assets | Incomplete for older or informal networks |
| Dependency models | How failures spread | Rely on assumed backup durations |
| Household surveys | Service as experienced | Self-report and sampling limits |
The current service level is R0: information and enquiries. An enquiry receives a reference and names the next step; applications, payments, compute allocations and registrations open only when their team, terms and review capacity exist.
