The problem to investigate
Rainwater installations may fail through clogged gutters, damaged tanks or forgotten inspection routines. Communities can be told that water is available even when its quality or safe intended use is uncertain.
02 / THE BLUEPRINT
A possible solution
Create a scheduled condition checklist for roof channels, covered storage, cleaning responsibility and repairs. Clearly label approved uses as determined by qualified local water professionals.
03 / THE BLUEPRINT
Start without an app
Use a laminated maintenance chart, paper work orders and a named caretaker before considering sensors or remote monitoring.
04 / THE BLUEPRINT
Technology that could help
A mobile form could log inspections and photos with permission, remind accountable staff about maintenance and flag missing records. It must never certify potability or substitute for laboratory testing.
05 / THE BLUEPRINT
Your first experiment
- Choose one authorised non-clinical building and review its existing water-use rules.
- Walk through a visual-only inspection with an experienced caretaker.
- Design an inspection log and identify who can request repairs.
- Test two maintenance cycles and review whether staff actually follow up.

People, resources and cost drivers
Needs building consent, maintenance budget, local plumbing knowledge and professional water-quality advice. UNICEF sustainability-monitoring guidance is useful context: https://www.unicef.org/documents/sustainability-checks-guidance-design-and-implement-sustainability-monitoring-wash
07 / THE BLUEPRINT
What to validate — and when to stop
Verify that each recorded defect has an owner and documented disposition. Stop if a green dashboard is interpreted as proof the water is safe to drink.
08 / HYPOTHESIS TO TEST
Potential impact and how to measure it
Track completed inspections, repair lead time and verified operational availability for approved uses. Do not extrapolate health outcomes from maintenance logs.
09 / THE BLUEPRINT
Risks and safeguards
Contaminated water is a serious risk. Never advise drinking captured water without an approved safety assessment; avoid unqualified design modifications and unsafe roof access.
10 / THE BLUEPRINT
Who might pay or maintain it
A school or property group can budget regular inspection and cleaning. Replicable paper formats should remain available to sites with no smartphone.
