City Water Security
Remove blind spots across source, network, sewage, stormwater, groundwater and growth.
Define the service failure before selecting infrastructure.
Cities often manage water supply, sewerage, stormwater and land growth in separate systems.
Water imported from distant regions can hide local leakage and ecological cost.
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.
No unified urban water balance
Treat this as a hypothesis until records, field observation, seasonal evidence and credible alternatives are checked.
Peripheral settlements excluded
Treat this as a hypothesis until records, field observation, seasonal evidence and credible alternatives are checked.
Network condition unknown

Growth approvals ignore service capacity

Components that must work together.
Source and demand account
Define the responsible actor, operating standard, input, handoff, maintenance requirement, failure trigger and evidence record.
Treatment, storage and distribution
Define the responsible actor, operating standard, input, handoff, maintenance requirement, failure trigger and evidence record.
Leakage and household service
Define the responsible actor, operating standard, input, handoff, maintenance requirement, failure trigger and evidence record.
Sewerage, treatment and reuse
Define the responsible actor, operating standard, input, handoff, maintenance requirement, failure trigger and evidence record.
Stormwater, flood and recharge
Define the responsible actor, operating standard, input, handoff, maintenance requirement, failure trigger and evidence record.
Groundwater and future demand
Define the responsible actor, operating standard, input, handoff, maintenance requirement, failure trigger and evidence record.
Match intervention to hydrogeology, settlement and service capacity.
Publish a city water and wastewater flow account.
Zone service, loss and quality performance.
Integrate land use, drainage and groundwater.
Plan reuse and demand management before new sources.
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
Create a complete water account for one urban zone including informal and peripheral settlements.
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.
