Dealing With the Karnataka State Pollution Control Board (KSPCB)

The Karnataka State Pollution Control Board (KSPCB) enforces the Water Act, 1974, the Air Act, 1981 and the waste rules under the Environment (Protection) Act, 1986 in Karnataka. It grants consent for establishment and operation to factories, apartment complexes, hospitals and commercial buildings, inspects and samples, issues show-cause notices and closure directions, and can have power and water cut. In Bengaluru, a large share of its work concerns sewage: apartment STPs, commercial buildings and the city's lakes. Its orders go on appeal to the state appellate authority or the NGT Southern Zone Bench at Chennai.

This page is for three kinds of reader in Karnataka: apartment associations and builders dealing with STP notices, factory and hospital managements facing consent or closure issues, and residents who want KSPCB to act on sewage, smoke or effluent.

The essentials

What does KSPCB regulate, and why are apartment associations hearing from it?

KSPCB regulates anyone in Karnataka who discharges sewage or trade effluent, emits air pollutants or handles certain wastes. Under section 25 of the Water Act and section 21 of the Air Act it grants consent for establishment before a project is built and consent for operation before it runs. It issues authorisations under the Hazardous Waste Rules 2016 and the Bio-Medical Waste Management Rules 2016, and works with local bodies on plastic and solid waste.

Apartment associations hear from the board because a large residential complex with its own sewage treatment plant is, in law, discharging sewage, and so falls within the consent system. In Bengaluru, where many complexes are outside the reach of the city's sewer network or are required to treat and reuse their own wastewater, the STP is often the single largest environmental obligation a resident body carries. When the board samples treated water and it fails, the notice goes to whoever holds the consent or runs the plant.

KSPCB does not award compensation to people harmed by pollution, decide building plans or grant groundwater permissions. Those belong to the NGT, the planning and municipal authorities and Karnataka's groundwater authority respectively.

Consent for apartment complexes and commercial buildings

For a covered residential or commercial project, consent for establishment is taken by the builder before construction, usually alongside the environmental clearance where the project is large enough to need one. Consent for operation follows before occupation. The consent sets the STP capacity, the treated water standards, how the treated water is to be reused (flushing, gardening, cooling), how sludge is handled, and the monitoring and reporting the occupier must do.

Problems usually start at handover. The builder hands the STP to the association, often undersized for the number of flats actually occupied, with membranes or blowers near the end of their life, and with the consent still in the builder's name or expired. The association inherits a plant it did not design and a legal position nobody explained. Our guide on running an STP without consent looks at the risks, and STP non-compliance and sewage cases at the remedies.

The STP notice: is the builder or the association responsible?

It depends on facts, and the board will look at three: whose name the consent is in, who was operating the STP when the violation was found, and whether formal handover had taken place. Before handover, the builder is usually the occupier responsible. After handover, the association running the plant generally is, though a builder who handed over a defective or undersized plant cannot simply walk away, and the association can pursue it under the sale agreements, the state real estate law and, where pollution is involved, before the NGT.

When Advocate B.K. Singh advises an association on a KSPCB notice, he first asks for the consent order, the handover documents and the STP operator's contract, because those three papers usually decide who the board can hold liable and who the association can turn to for the cost of repairs. An association that replies to the board without them often accepts responsibility it did not need to.

Papers an association should insist on when the builder hands over

How an apartment association should respond to a KSPCB notice on its STP

These steps also work, with small changes, for a hotel, hospital or commercial building that runs its own STP.

Bengaluru's lakes and sewage: what KSPCB can and cannot fix

Bengaluru's lakes were built as a connected chain of tanks, and much of the city's untreated or partly treated sewage now reaches them through storm water drains. The froth and fires on Bellandur and Varthur lakes made national news and have been before the NGT. Residents living around a polluted lake usually find that several agencies share the blame: the water supply and sewerage board for sewage lines and treatment plants, the city corporation for storm water drains and solid waste, the lake authority or owning department for the lake itself, and KSPCB for monitoring and enforcing standards.

KSPCB can sample inflows and outflows, act against apartment complexes, commercial buildings and industries discharging into drains, and direct the sewerage board to meet standards at its plants. It cannot itself build a sewer or desilt a lake. When a lake case reaches the NGT, the tribunal usually brings all these agencies in together. See who is responsible for municipal sewage in a lake and our page on lake encroachment and pollution.

Where to go in Karnataka for which problem

Factories and industrial areas: consents, renewals and inspections

Industrial units in Karnataka, many of them in KIADB industrial areas around Bengaluru such as Peenya, Bommasandra, Jigani and Doddaballapur, need consent under both Acts unless they fall in the white category. Applications go through the board's online consent system and are examined by the regional office, with red category and larger units scrutinised more closely. Consent periods, inspection frequency and the conditions imposed depend on the category and size of the unit.

Most industrial trouble comes from three sources: a renewal filed late, expansion or a new product without consent, and an effluent treatment plant or air pollution control system that does not perform when sampled. Electroplating, pharmaceutical, food processing and foundry units are frequent recipients of notices. Recent amendments and notifications have changed some consent requirements and exemptions, so a unit relying on advice from several years ago should check the current position.

Hospitals, clinics and labs: bio-medical waste and sewage

Every healthcare facility that generates bio-medical waste, from a large hospital to a small clinic or diagnostic lab, needs authorisation from KSPCB under the Bio-Medical Waste Management Rules 2016. Waste must be segregated into the colour-coded categories (yellow, red, white translucent and blue), stored safely and handed only to the common bio-medical waste treatment facility serving the area, with records kept for every pickup.

Hospitals also generate sewage and, in many cases, run their own STPs and DG sets, so they need consent under the Water and Air Acts as well. KSPCB inspections of hospitals typically look at the waste storage room, the treatment facility receipts, the STP and the annual report. Complaints from neighbours about hospital waste dumped in vacant plots are taken seriously, because the source can usually be traced from the waste itself.

Mining, fly ash, foundries and the coast

Outside the capital, KSPCB's work looks very different. Iron ore mining in the Ballari region, which led to Supreme Court-supervised restrictions after illegal mining came to light, and the steel and sponge iron plants around Ballari and Hosapete raise dust, water and waste issues. Raichur's thermal power plants bring fly ash and ash pond questions. See environmental cases in Ballari.

Mangaluru and the coastal districts have a refinery, petrochemical and fertiliser units, a major port and fishing communities, so effluent, air emissions and coastal regulation zone issues all arise there; CRZ matters themselves belong to the coastal zone management authority. Belagavi and Hubballi-Dharwad have foundry and engineering clusters, and quarrying in the Western Ghats districts brings dust and blasting complaints. See environmental cases in Mangaluru.

Show-cause notice, closure and disconnection: how KSPCB escalates

A KSPCB matter usually begins with an inspection and a sample, moves to a show-cause notice, and only then to directions under section 33A of the Water Act or section 31A of the Air Act. Those directions can order closure, regulate operations, or require the electricity supply company and water supplier to cut supply. For apartment complexes the board generally prefers time-bound directions to closure, since residents live there, but persistent failure can still lead to coercive steps and environmental compensation.

A reply should be specific and supported: what was wrong, what has been done, what remains and by when. Since the Jan Vishwas Act 2023 and the Water Amendment Act 2024, many violations also attract monetary penalties fixed by an adjudicating officer, so the reply may later be read in that proceeding too. Do not ignore a notice because the STP operator or consultant says it is routine.

How KSPCB orders are challenged

For the first-stage appeal, see appeals before the state appellate authority.

The NGT bench and High Court for Karnataka

Karnataka is covered by the NGT Southern Zone Bench at Chennai, along with Tamil Nadu, Kerala, Andhra Pradesh, Telangana, Puducherry and Lakshadweep. Filing is through the NGT's e-filing system, and hearings can be attended by video conference, so an association in Bengaluru or a village group near Ballari does not have to travel for every date.

The Karnataka High Court sits at Bengaluru with benches at Dharwad and Kalaburagi. Its writ jurisdiction remains for constitutional questions and matters outside the NGT's seven Acts, and it has heard many lake and urban planning cases over the years. Where the dispute is squarely about pollution under the Water Act, Air Act or EP Act, it will usually send parties to the NGT.

Complaining to KSPCB about a factory, building or hospital

Write to the KSPCB regional office for your area and keep proof of delivery. Identify the source precisely: the name and address of the factory, apartment complex or hospital, and where its discharge goes. Describe what you see and when, with dated photos and video. Ask for inspection, sampling of the discharge and a copy of the report. If a neighbouring complex is letting raw sewage into a storm water drain, photograph the outlet and the colour of the water in dry weather, when there is no rain to explain it.

Give the board a reasonable time, then use RTI to ask what was done. Advocate B.K. Singh's usual advice to residents' welfare associations is to send one well-documented complaint signed by the association rather than many individual ones, and to keep every acknowledgment. If the board does not act, that file supports an NGT application at Chennai.

What we do in KSPCB matters

• Apartment and building STP matters. We advise associations and builders on consent transfer, replies to notices and the respective liability of each.
• Industrial consents and notices. We review consent conditions against actual operations and prepare replies to show-cause notices with technical support.
• Closure and disconnection. We work on revocation and restoration of supply, and file appeals where an order is wrong.
• Appeals. We appear before the state appellate authority on consent decisions and before the NGT Southern Zone Bench on directions.
• Lake and sewage cases. We help residents bring the right agencies before the NGT when sewage or encroachment is destroying a lake.
• Builder disputes. We help associations recover the cost of defective STPs where pollution issues overlap with the sale agreement.

Mistakes we see in Karnataka

Associations accept handover without checking the consent, the STP's condition or its design capacity, then discover the problem when KSPCB samples the outlet. Some run the STP only during the day to save power, or bypass it when the plant is overloaded, which shows up in any surprise sample. Factories file renewals late and expand without consent, the same pattern seen in every state.

Residents complaining about lakes often write to one agency and give up when it says another is responsible. In lake cases, the useful step is to write to all of them together, and to KSPCB specifically for sampling.

When to get legal help, and related pages

An association can handle a routine query from the board with its STP operator's help. Legal advice is worth taking when a show-cause notice raises liability between builder and association, when the board threatens disconnection or compensation, when a factory faces closure or consent refusal, or when residents have complained in writing and the board has done nothing.
