Section 01
Where the problem happens
Define the service failure before selecting infrastructure.
“Treated” is not one universal quality; risks depend on contaminants, exposure and use.
Reuse systems fail when demand, conveyance, price and liability are unclear.
Required local context
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.
Data reference table
Evidence Snapshot
Read each value with its reporting period, population and limitations. A historical national reference is not a local baseline or proof that an IFT proposal works.
2 source-linked reference records. 3 measurement records still need data and a review of their relevance.
| Signal | Reference Value | Period / Population | How to Read It | Source Status |
|---|---|---|---|---|
| Estimated urban sewage generation | 72,368 million litres per day Reported value — scope clarification required | 2021 published inventory; uniform underlying observation cut-off not established Urban areas in India covered by the CPCB assessment | A historical national urban wastewater-load estimate. Limitations: An estimate rather than a measurement of every discharge. It is not current city-level sewage generation or industrial effluent volume. | Ministry of Jal Shakti / Central Pollution Control Board Official government release Record type: official assessment estimate Published: 2021-08-05 Publication checked: 2026-11-04 Period / coverage needs clarification |
| Available urban sewage-treatment capacity | 31,841 million litres per day Reported value — scope clarification required | 2021 published inventory; uniform underlying observation cut-off not established Urban India; treatment capacity reported with the CPCB assessment | Capacity can be compared with the same assessment’s generation estimate. Limitations: Available capacity is not actual operating throughput, compliant effluent or safely reused water. A local plant needs current operating and quality records. | Ministry of Jal Shakti / Central Pollution Control Board Official government release Record type: official capacity assessment Published: 2021-08-05 Publication checked: 2026-11-04 Period / coverage needs clarification |
| Compliant reused volume | Not established Data required — not zero | Reporting period: Information Required Population and geography: Information Required | Proposed measure; no observed value is established here. Limitations: Define the measure, unit, reporting period and covered population; obtain a traceable dataset and review its suitability for this topic before using a number. | Source organisation: Information Required Direct source URL: not yet verified Source publication date: not established Verification status: Data required |

Different surveys, administrative records, estimates and reporting years are not interchangeable. No combined IFT score is calculated from these rows.

Section 02
Why the problem happens
Test the full source-to-service chain.
End use selected after plant design
Treat this as a hypothesis until records, field observation, seasonal evidence and credible alternatives are checked.
Standards and monitoring not use-specific
Treat this as a hypothesis until records, field observation, seasonal evidence and credible alternatives are checked.
Users lack reliable quantity or quality
Treat this as a hypothesis until records, field observation, seasonal evidence and credible alternatives are checked.
Recharge proposed without hydrogeology
Treat this as a hypothesis until records, field observation, seasonal evidence and credible alternatives are checked.
Section 03
How the parts work together
Components that must work together.
Agriculture and industrial reuse
Define the responsible actor, operating standard, input, handoff, maintenance requirement, failure trigger and evidence record.
Landscaping and construction
Toilet flushing and municipal use
Application-specific treatment
Safe recharge where justified
User contracts and monitoring
Section 04
A solution suited to India
Match intervention to hydrogeology, settlement and service capacity.
Choose use first, then treatment and monitoring barriers.
Define buyer, quality, volume, price and failure response.
Separate potable and non-potable networks clearly.
Require stringent independent review for recharge or potable applications.

Section 05
Roadmap
Diagnose, protect, pilot, measure and institutionalise.
- 0–90 DAYS
- Verify & protect
Confirm the location, affected users, service chain, immediate health or safety risk, responsible agency and existing evidence.
- 3–18 MONTHS
- Controlled pilot
Build one closed reuse agreement with continuous operations records and periodic independent testing.
- 1–5+ YEARS
- Durable system
Fund operations, preventive maintenance, skilled teams, monitoring, public reporting, correction pathways and independent evaluation.
