Sewage problems usually show up as a smell first: a choked drain, an overflowing manhole, or treated water from the society STP that is clearly not treated. Behind the smell is a legal question about who is responsible for running the plant properly and who should pay to fix it.
We act for residents and RWAs who are dealing with a non-working STP or a sewage discharge into their area, and for builders, maintenance agencies and societies who have received a notice or penalty from the pollution board about their STP.
हिंदी में सारांश
सोसाइटी या कॉम्प्लेक्स का STP ठीक से न चलने पर बदबू, ओवरफ़्लो और नाले में गंदा पानी जाना आम समस्या है। STP को जल अधिनियम के तहत Consent to Operate चाहिए और उसका पानी तय मानकों के अनुसार होना चाहिए। RWA शिकायत कर सकती है, और बिल्डर या मेंटेनेंस एजेंसी पर बोर्ड नोटिस और पर्यावरणीय मुआवज़ा लगा सकता है।
Is this your situation?
- Your society STP has broken down or is switched off to save power
- Treated water from the STP smells or looks untreated
- Sewage overflows into the street, a park or basement
- A builder handed over the society without a working STP or its consent
- The board issued a notice or compensation demand about the STP
- A municipal drain or STP is discharging untreated sewage into a river or pond
Who is responsible
Builder
Until handover, and for defects in design or capacity of the STP.
RWA or society
After handover, for running the plant, renewing consent and keeping records.
Maintenance agency
Under its contract with the builder or RWA, for daily operation.
Pollution board
For consent, monitoring and enforcement action.
Municipal body
For public sewers and city STPs, and for sewer connections.
NGT
For orders when the others do not fix the problem.
What the rules require
An STP that discharges treated water needs consent to operate from the pollution board under the Water (Prevention and Control of Pollution) Act, 1974. The treated water must meet the standards in the consent, and the operator should keep logbooks, flow records and lab reports. Large projects usually also have conditions in their environmental clearance about the STP, dual plumbing and reuse of treated water.
The NGT has repeatedly treated sewage discharge as a serious matter and has ordered environmental compensation against societies, builders and municipal bodies for running STPs badly.
Builder, RWA or agency: sorting out responsibility
Many STP disputes are really handover disputes. The builder says the plant was working when handed over; the RWA says it was undersized or never commissioned. Settling this needs the approved drawings, the EC and consent conditions, the commissioning record and the handover documents.
If the builder is at fault, the RWA can ask the board to act against it, raise the issue under the RERA law if the project is registered, and in serious cases approach the NGT. If the RWA has taken over the plant, it should get the consent transferred into its name and fix gaps before the board does.
| Problem | What to check | Likely route |
|---|---|---|
| STP not working after handover | Handover papers, capacity, commissioning record | Notice to builder, complaint to board |
| Consent expired | Who holds the consent and its validity | Renewal application, regularisation |
| Board notice or compensation | Inspection report and test results | Reply with fixes and evidence |
| Municipal sewage into a water body | Which body runs the drain or STP | Complaint, then NGT application |

Frequently Asked Questions
Does a housing society need consent for its STP?
Generally yes, if it runs an STP and discharges or reuses treated water. Requirements vary a little by state, so check with the board for your area.
Can the board fine our society for the STP?
Boards and the NGT have imposed environmental compensation on societies, builders and agencies for non-working STPs. The amount usually depends on the period and the extent of the violation.
Who pays for repairing an undersized STP?
If it was undersized when built, the builder is usually responsible. If it has been badly maintained after handover, the cost normally falls on the society.
Can the RWA go to the NGT against the builder?
Yes, where untreated sewage is being discharged. For purely contractual issues, RERA or a civil claim may be better.
What records should an STP keep?
Daily flow, running hours, chemicals used, sludge disposal and periodic test reports of the treated water.
Can treated water be used for gardening?
Yes, and many approvals require reuse for flushing and gardening, provided it meets the prescribed standards.
