Pollution watchdog to support apartments for better STPs

Residents are worried that builders are not ensuring that the STPs function well and comply to standards. KPSCB chairman Sadashivaiah promises to redefine STP norms and STPs certification by March.

Apartment associations in the city have got assurance from the state Pollution Control Board (KSPCB) that Sewage Treatment Plant (STP) norms for apartments will soon be re-defined. An informal group of residents from various apartments across Bangalore, have been in talks with the Board for over six months, many of them having faced issues with STP quality and adherence to regulations.

Board Chairman A S Sadashivaiah said that the new processes will be finalised by March and will be implemented by June. Board will redefine aspects such as stringent checks before approving STPs, holding builders accountable for STP quality etc.

Sadashivaiah announced this after a meeting with the residents on November 26th. “A team of 4-5 experts including STP consultants and Board officials will be formed. Builders’ association representatives will also be involved in the process,” he said. The committee is yet to be formed.

Residents had complained that builders set up STPs that do not meet the requirements of apartments. These are handed over to residents even before the apartments are fully occupied. “Only when the apartments are fully occupied, residents find that the STP is not equipped to handle the load. Many problems are due to faulty design and engineering. But since they are already handed over, residents end up paying for repairs,” said one of the citizens, giving a presentation at the meeting.

Aras said that Board should certify STPs on their quality before giving the builder consent to start operating them. Currently KSPCB does not certify STPs on their design and operation, but only checks the quality and quantity of treated water. Hence additional checks are needed, said residents.

Currently, a Consent for Operation (CFO) is required before starting operation of the STP. Residents say that the CFO process should be in two stages – before operation starts, a Provisional CFO (PCFO) should be issued; a Final CFO (FCFO) should be issued after ensuring that the STP runs successfully over a period of time.

“PCFO should be made mandatory for getting Occupancy Certificate (OC) for the building. And only after getting the FCFO, builder can hand over the STP to residents,” they say.

They also demanded that a checklist be used to record the STP components and verify design while giving consent to builders. This information should then be passed on to residents so that there is transparency on the STP’s status.

“Currently these (components and design) aspects are not recorded. If there are flaws, Board later demands that resident make design changes. But these should be checked in the initial stages itself,” said Dr Ananth Kodavasal, STP expert, who was also present at the meeting. Residents also demanded that the Board should take action against builders under the Water Act if flaws are found during independent audits.

Another demand was to waive the fee for renewing CFO annually. Instead of having to pay this fee, apartments should be incentivised for treating sewage; independent houses do not treat their sewage and dump it in lakes, but are not required to pay any fee. So there is no rationale for collecting huge fee from apartments, and there is no clarity on how this money is being used, felt the citizens.

Apartments with area more than 20,000 square metres in non-core areas are classified under ‘Red’ industries (most polluting), and correspondingly high fee is collected from them. This fee also goes up according to the capital investment of the project ie., a luxury apartment may have to pay more than a regular apartment even if the number of residents in both are the same.

Speaking to Citizen Matters, Sadashivaiah said that fee collection cannot be stopped suddenly as this was a huge revenue source for the Board. “We will decide on that later; for now other processes will be strengthened. We will insist that the builder will have to operate the STP for at least five years before handing it over to the associations, and will make sure that they comply,” he said.

Board also plans to publish a list of empanelled STP consultants in its website, so that public and builders can use their services.

    This will be yet another source of income.

  2. S Srinivasan says:

    Having STP in an apartment complex is very expensive and the residents have to bear the perennial nuisance from the pollution control board of repeated inspection and penalties. Instead, the PCB themselves should have a centralised STP system and charge the Multistorey complexes according to the usage. Presently, only those who have STP are issued notices and thousands of apartment complexes have no such facility. The builders are equally responsible for not handing over a fully functional STP and the burden falls on the association who have no means to meet such a high continuous expenditure. There are many Industries who do not have such a system and the highly polluted water is let into the lakes and drains. No action is taken against the defaulters due to rampant corruption. I do not see any need for domestic STPs while all the Industries should have in their premises. This is because the industrial effluents are heavily toxic. I suggest that Domestic STPs should have solid filters and clarifiers with less stringent treatment due to low toxicity.

New look, old problems: Residents question Rs 43-crore Retteri Lake restoration plan

Residents want the government to urgently address the problem of sewage contamination and encroachments on the lake.

As the population of metropolitan cities like Chennai continues to grow, the government faces an uphill task β€” coming up with alternative solutions to provide drinking water for the city. While schemes such as desalination plants aim to meet water needs, the public seeks more natural and environment-friendly water sources. This is where Retteri Lake, one of the major lakes in Chennai, plays a pivotal role. When Chennai faced a major drought in 2019, water from Retteri Lake was used to meet the shortfall in drinking water supply. The lake also remains a source of groundwater recharge for the neighbourhood.…
