Reliable Water Supply
Make service predictable in quantity, pressure, quality and repair.
Define the service failure before selecting infrastructure.
Nominal capacity or connection counts can hide intermittent, low-pressure and unequal service.
Intermittency can increase contamination risk and household storage burden.
Record state, district, city/block, village/ward or supply zone; season and date; source or asset; affected users; observed service; measurement or sample method; photo/document where safe; and uncertainty. Never imply 100-metre accuracy unless the evidence genuinely supports it.
Test the full source-to-service chain.
Source and storage insufficient for peaks
Treat this as a hypothesis until records, field observation, seasonal evidence and credible alternatives are checked.
Network zones poorly understood
Treat this as a hypothesis until records, field observation, seasonal evidence and credible alternatives are checked.
Leakage and unauthorised flows not distinguished
Treat this as a hypothesis until records, field observation, seasonal evidence and credible alternatives are checked.
Reactive maintenance and weak spares
Treat this as a hypothesis until records, field observation, seasonal evidence and credible alternatives are checked.
Components that must work together.
Supply hours and continuity
Define the responsible actor, operating standard, input, handoff, maintenance requirement, failure trigger and evidence record.
Pressure and storage
Define the responsible actor, operating standard, input, handoff, maintenance requirement, failure trigger and evidence record.
Leakage and non-revenue water
Define the responsible actor, operating standard, input, handoff, maintenance requirement, failure trigger and evidence record.
Interruption records
Define the responsible actor, operating standard, input, handoff, maintenance requirement, failure trigger and evidence record.
Repair and maintenance
Define the responsible actor, operating standard, input, handoff, maintenance requirement, failure trigger and evidence record.
Customer communication
Define the responsible actor, operating standard, input, handoff, maintenance requirement, failure trigger and evidence record.
Match intervention to hydrogeology, settlement and service capacity.
Create district-metered or otherwise measurable supply zones.
Track pressure, continuity, quality and customer experience together.
Prioritise active leak control and preventive maintenance.
Publish interruption notices and repair service levels.
Diagnose, protect, pilot, measure and institutionalise.
Verify & protect
Confirm the location, affected users, service chain, immediate health or safety risk, responsible agency and existing evidence.
Controlled pilot
Establish one measured service zone with a baseline water balance, pressure plan and repair team.
Durable system
Fund operations, preventive maintenance, skilled teams, monitoring, public reporting, correction pathways and independent evaluation.
Measure service and outcomes—not assets alone.
Water interventions can transfer risk across people, places and time.
