Circular Water Economy
Recover safe water, energy and nutrients while accounting for residues and risk.
Define the service failure before selecting infrastructure.
Recovery can create products with pathogen, chemical or heavy-metal risk.
Revenue projections can ignore segregation, testing, energy and residual disposal.
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.
Feedstock quality not controlled
Treat this as a hypothesis until records, field observation, seasonal evidence and credible alternatives are checked.
Technology selected before market
Treat this as a hypothesis until records, field observation, seasonal evidence and credible alternatives are checked.
Product standards and liability unclear
Treat this as a hypothesis until records, field observation, seasonal evidence and credible alternatives are checked.
Cross-pillar ownership fragmented
Treat this as a hypothesis until records, field observation, seasonal evidence and credible alternatives are checked.
Components that must work together.
Treated-water recovery
Define the responsible actor, operating standard, input, handoff, maintenance requirement, failure trigger and evidence record.
Biogas and energy
Define the responsible actor, operating standard, input, handoff, maintenance requirement, failure trigger and evidence record.
Nutrient recovery
Define the responsible actor, operating standard, input, handoff, maintenance requirement, failure trigger and evidence record.
Approved biosolids
Define the responsible actor, operating standard, input, handoff, maintenance requirement, failure trigger and evidence record.
Agriculture linkages
Define the responsible actor, operating standard, input, handoff, maintenance requirement, failure trigger and evidence record.
Product quality and markets
Define the responsible actor, operating standard, input, handoff, maintenance requirement, failure trigger and evidence record.
Match intervention to hydrogeology, settlement and service capacity.
Characterise inputs and reject hazardous streams.
Select recovery by full mass, energy and financial balance.
Test each product before approved use.
Publish residual destination and environmental monitoring.
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
Operate one traceable wastewater-to-resource chain with independent quality and field-use monitoring.
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.
