Who Pays for Restoring a Polluted Lake or Pond?

The person or body that damaged the lake or pond pays first. Under the polluter pays principle, which the National Green Tribunal must apply under section 20 of the NGT Act, a factory, builder, dairy cluster or encroacher that fouled or filled a water body can be made to bear the full cost of putting it right, not just a fine. Where the damage comes from a town's sewage or years of neglect, the municipality or state that controls the water body is answerable. Public schemes fill the gap after that. The hard part is proving who caused what, fixing a real cost, and seeing the money spent on the lake.

This guide is for panchayat members, RWAs, farmers and residents who want a damaged water body brought back and are being told there is no money. It is also for builders, units and municipal officers who have been asked to pay.

If your problem is that the pond is being occupied or filled right now, start with our guide on getting an encroached village pond restored and the topic page on lake, pond and wetland encroachment cases. This page deals with the money question that follows.

The essentials

Who actually pays to clean up a polluted lake or pond?

Liability runs in layers. At the top is whoever caused the damage: a unit discharging effluent, a builder dumping debris, a colonizer who filled the edge to sell plots, a dairy cluster draining dung water. Indian environmental law does not stop at fining such a person. Since the Supreme Court's decisions in Indian Council for Enviro-Legal Action v Union of India and Vellore Citizens' Welfare Forum v Union of India (both 1996), the polluter pays principle has meant paying for the harm and for restoring the damaged environment as well.

The second layer is the custodian. Every lake and pond belongs to, or is managed by, somebody: the gram panchayat or gram sabha for most village ponds, the municipal corporation or council in towns, a development authority in planned sectors, the irrigation or forest department for some reservoirs and wetlands. That body has a legal duty to protect the water body. If its own drains feed sewage into the lake, or it watched the lake being filled and did nothing, the NGT can direct it to restore the lake and pay for it.

Only after those two layers does public money come in. Officials sometimes present schemes as the only answer: we will clean it when funds come. That gets the order wrong. Scheme funds can supplement recovery from the people responsible. They do not let those people off.

Who pays, by the cause of the damage

Most damaged lakes have more than one cause. Work out which of these apply before deciding whom to pursue.

A lake on the edge of a growing town often has all of these at once. That is normal, and the tribunal can divide the cost.

The legal basis for making someone pay

When a factory has polluted the lake, how much can it be made to pay?

More than the board's penalty. Environmental compensation levied by a board under the CPCB method is worked out from factors such as the industry's category, the days of violation, the unit's size and location. It punishes and deters. It is not designed to measure what it will cost to remove contaminated sediment from the bed of a particular pond, treat the water, and restore what was lost.

The NGT can go further. Under section 15 it can direct the unit to pay for actual restitution, and it commonly asks a joint committee (the CPCB, the State Board, the District Magistrate, sometimes an expert institution) to assess both the damage and what restoration will cost. The unit can then be directed to deposit that amount, or to do the work itself under supervision, in addition to any compensation already levied.

Units often argue that the lake was already dirty or that their effluent met the standards on the day of sampling. A fair case deals with that. A sediment test near the unit's outfall showing the same metals or chemicals the unit uses is often more telling than a single water sample, because sediment holds what the water has carried over months.

Our lake is dying from the town's sewage. Can the municipality be made to pay?

Yes. A municipal body is not exempt from the Water Act, and letting untreated sewage into a lake through its own drains is a continuing violation. In recent years the NGT has directed state governments to pay large amounts of environmental compensation for failing to treat sewage and manage waste, and has asked that such money be kept in a separate account and spent on fixing the problem. The same logic applies to a single lake: the authority whose drains foul it can be ordered to intercept and divert them, treat the flow, and fund the clean-up.

The practical difference from a factory case is that you are asking one arm of government to spend public money, so what the NGT usually wants is a time-bound plan: which drains will be tapped, where the sewage will go, which STP has capacity, and who is paying for each part. Asking only for compensation gets you less than asking for that plan with costs attached. The mechanics of the outfall itself are covered in our guide on municipal sewage entering a lake or river.

Someone filled part of the pond. Who pays to dig it out again?

The person who filled it. Removing earth, debris and structures from a water body costs money, and state revenue laws and the NGT both allow that cost to be charged to the encroacher. In practice the tehsildar or SDM orders eviction, the administration carries out the removal, and the cost is recovered from the occupant, sometimes as arrears of land revenue. Where a builder or colonizer filled a pond to sell plots, the restoration cost can be large, and it should be claimed specifically rather than left to a general order to remove encroachment.

The difficult cases are those where the filling is old and the land has been sold on to families who built small houses in good faith. The tribunal and the courts have generally refused to treat a water body as lost just because people now live on it, but they do look at who profited. Our guide on legal action against illegal filling of a lake or pond covers the eviction side; for restoration, the useful step is to trace the chain from the person who first filled and sold.

What if many people polluted the lake and no single culprit can be named?

This is the usual situation, and it does not defeat a claim. The NGT can apportion. It asks the committee to identify the sources (drains, outfalls, dumping points, encroachments), estimate how much each contributes, and divide the cost of restoration accordingly. A unit responsible for heavy-metal contamination may be charged for sediment removal near its outfall; the municipality for sewage interception; an encroacher for removal of fill. The figures are rarely exact, and the tribunal does not demand that they be.

Where part of the damage is historic and cannot be tied to anyone, the state carries that share. Indian courts treat the state as a trustee of lakes and rivers for the public, and a trustee that lets the property decay cannot plead lack of budget. That is the argument for including the state and the relevant department as respondents. Our guide on an NGT case against an authority that will not act explains how.

Which government funds can be used for lake and pond restoration?

Several, and their names and rules change, so check current guidelines. The Centre's scheme for lakes and wetlands (now the National Plan for Conservation of Aquatic Ecosystems) shares costs with the states. Urban water body rejuvenation has been part of AMRUT. Village pond desilting is often taken up under MGNREGA, and the Amrit Sarovar campaign revived ponds in every district. District Mineral Foundation funds in mining districts and company CSR spending can also pay for this work.

Two warnings. Desilting a pond under a labour scheme while sewage still flows in is wasted effort. And public funding does not cancel the liability of whoever caused the damage. Where a polluter has been ordered to deposit money and a scheme also funds work on the same lake, tie both to one restoration plan so nothing is paid for twice.

How is the cost of restoring a lake worked out?

From a restoration plan, not a guess. A proper plan for a lake or pond usually covers stopping the inflows (intercepting drains, diverting sewage to an STP, closing illegal outfalls), removing fill and encroachments, desilting, dealing with contaminated sediment as waste where needed, restoring inlets and outlets so the water body fills and drains as it used to, fencing and a walkway or buffer, and catchment work so silt and garbage stop arriving. Each item has a cost, and the plan should say who pays for which item.

The NGT often asks the committee or an expert institution to prepare or vet such a plan. Residents can add what they know: where the old inlet ran, how far the water spread in the monsoon. Revenue maps and old satellite imagery are the best proof of original extent. A plan that restores only the shrunken lake that exists today is a plan that rewards the encroachment.

How to make the responsible parties pay for restoration

This is the order that usually works for a gram panchayat, RWA or group of residents. The early steps cost little and build the record the NGT will want to see.

A common mistake is to ask the tribunal only to order the lake cleaned. Ask who should pay, how much, into which account, and who will check the work. Our page on compensation for pollution damage explains how damage claims sit alongside restoration.

What to collect to show who should pay

The NGT ordered restoration. How do we make sure the money is spent on the lake?

By building safeguards into the order. Ask for the amount to go into a separate account used only for this water body, a named nodal officer, a staged timeline and periodic reports to a monitoring committee. Without this, money deposited with a board can sit unused for years.

When Advocate B.K. Singh drafts the relief in a restoration case, he asks for the stages to be tied to the order of work, because desilting a pond before the drains are diverted simply means paying to desilt it twice. If deadlines pass, an NGT order is executable as a decree of a civil court under section 25, and wilful non-compliance is punishable under section 26. Our guide to the NGT execution application covers that step.

For units, builders and panchayats facing a restoration demand

If a board or the tribunal is asking you to pay for restoring a water body, look first at the basis of attribution. Is there a sample from your outfall, or only from the lake? Does the committee report distinguish your contribution from that of others? Were you given a hearing before the amount was fixed? Environmental compensation levied by a board without proper notice can be challenged, and a restoration share fixed without a breakdown can be questioned in objections to the committee report. Our guide on challenging or claiming environmental compensation explains the routes.

Panchayats and municipal bodies can be respondents too. Their best protection is a record of having acted: resolutions, complaints, eviction proceedings started.
