Help! Someone else’s sewage in our pipes

While the apartment complex residents worry about untreated sewage in their drain pipes, the issue points to the larger problem of lack of sewage lines in the entire 7th and 8th phases of JP Nagar.

Residents of Elita Promenade, an apartment complex in JP Nagar 7th phase, are a worried lot. Elita has a strange problem – a sewage pipeline runs within the apartment’s compound, but it carries sewage not from the complex, but from other layouts.

The raw sewage flows in to the pipeline located along the compound wall and finally joins Jaraganahalli (Sarakki) lake located behind the complex. The sewage is from Uma Sanjeevini apartment and Guru Raghavendra Layout located next to Elita complex, outside its compound wall. The apartment however has its own Sewage Treatment Plant (STP) to process its sewage.

Elita residents complain that the line was laid without their knowledge. In addition to the threat of action by government for polluting the lake, they are concerned about health issues. "Since the line goes through our compound we may be held responsible," says Nagendran, a resident and an IT professional.

According to the Raghavendra layout residents, the pipeline arrangement to carry sewage from outside was made in 2005. The builder had encroached a rajakaluve (arterial storm water drain for Bangalore) which was running across the site marked for Elita. This cut off the sewage paths of the layout’s residents.

Raghavendra layout residents claim that they complained to the then Bommanahalli CMC Commissioner Udayshankar, who then ordered the compound wall to be demolished. "After this the builder said they would build a pipeline within their compound and we could connect our sewage pipes to it," says M S Nadakatti, former Secretary of Raghavendra Layout RWA. Nadakatti however adds that this was only verbal agreement. Citizen Matters has the pictures of the demolition provided by Nadakatti.

"After this the builder said they would build a pipeline within their compound and we could connect our sewage pipes to it," says Nadakatti. "There was a proposal to let our sewage be treated in their STP, but they said it would require more government permissions for higher capacity STP, and we dropped that proposal." Residents pooled together about Rs 4 lakh to build proper channels and connect them to the Elita line.The RWA is now disbanded due to lack of participation.

In Elita compound, sewage from Raghavendra Layout enters a closed pipeline, while that from Uma Sanjeevini apartment directly enters a storm water drain running along the compound. The sewage in this drain is visible. About 50 houses in Raghavendra layout are using this pipeline, says M M Green, former RWA President.

The builder for Elita Promanade is Keppel Land – a Singapore-based company – in partnership with Puravankara Builders. Keppel Land hasmajority share in the project and construction was entirely done by them. The apartment residents noticed the pipeline only recently as the line passes near the newly constructed B block. Nandakumar, a B block resident says that he noticed the pipeline about six months ago. For now, the builder is in charge of the complex as its construction is not yet complete and no apartment owners association has been formed. "The builder may be here for another year or so, but after that it will become our responsibility," he says. Keppel Land could not be reached for comment.

While the residents are worried about action from Pollution Board, sewage disposal into the lake is not a new phenomenon in this area. Being a new BBMP area, most of the houses do not have (Under Ground Drains) UGDs here. Most layouts were also not BDA-approved and are awaiting regularisation.

The nearly 69-acre lake, has been receiving sewage from the entire area for years. It is almost entirely covered by weed, emanates foul stench and causes mosquito menace.

What government agencies say:
BWSSB acknowledges that there are no proper sewage systems in the area. A few years ago BWSSB had laid a main sewage line from Chunchghatta, which enters the lake itself.

This line carries sewage from Chunchghatta, and many small layouts nearby. Even the BDA-approved RBI layout’s sewage line (also built by BWSSB) connects to this main line. RBI Layout’s line itself is used by Eswara layout, a part of Raghavendra layout etc.

"It is an open secret here that BWSSB lines and other sewage go into the lake. No action was taken so far. Most builders of layouts want to utilise entire space and don’t leave any space for making sewage pits, so residents are left with no option," says Jagdish, President of Federation of JP Nagar 7th and 8th phase RWAs. There are 43 layouts under the association.

Lake Development Authority (LDA) is aware of the situation. LDA’s CEO U V Singh says, "there is no other option for the residents in that area. They cannot let the sewage be in their premises, so we allow it."

Will the lake get some respite?

Jaraganahalli is one of the two lakes that LDA is supposed to develop, according to High Court’s directions in a PIL filed by the NGO Environment Support Group (ESG). According to this, LDA is supposed to complete rejuvenation of lake by 2014, but LDA has not formed an action plan yet. It says nothing can be done until sewage flow is stopped.

"We are co-ordinating with BWSSB on this. In the last meeting held about four months ago, BWSSB said that the works will start soon," says Singh.

BWSSB Assistant Executive Engineer (AEE) Mohammed Arief, who is in-charge of the UGD project, says that work will start in another month. "Contract has been given already. Konankunte, Puttenahalli, Jaraganahalli wards etc will be covered under this package. It is part of the larger project for setting up UGD in entire Bommanahalli zone at the cost of Rs 300 cr. It will be complete in two years," he says.

With this, 90% of sewage entry into Jaraganahalli lake can be stopped, says Arief. Singh agrees. "Sewage enters the lake mainly from this area; once it is stopped, cleaning the lake will be simple and cheap," he says. Currently LDA cleans area around the lake once in a while, but de-weeding is not done.

The last time LDA had cleaned up the lake was about 5-6 years ago, with funds from centre under the NLCP (National Lake Conservation Project). More than Rs 2 crore was spent to clean the lake at the time, but it became completely ineffective as sewage entry was not stopped. Only the fence that was built at that time remains now.

What is the ‘smartness’ quotient of Chennai?

The Smart City Advisory Forum was convened in Chennai only 5 times since 2016, showing minimal participation by elected representatives.

Chennai is among the first few cities to get selected under the Smart City Mission programme in 2016. As many as 48 projects under different categories were taken up under the scheme. With only a couple of projects left to be completed, isn't Chennai supposed to look 'smart' now? The much-hyped Central government scheme, launched in 2014, was envisioned to build core infrastructure and evolve 'smart' solutions that would make cities more livable and sustainable. But, a decade since, the reality on the ground may be a little different. While some of the facilities provided under these projects are under-utilised,…

Scenes from a community walk in Mumbai

When I moved to Mumbai, the city felt extremely 'walkable,' but a walking tour in Dadar broadened my definition of walkability.

When I moved to Mumbai in June 2023 for work, I found myself going for sight seeing to the city's tourist destinations. Though the city appeared to have consistent and wide footpaths almost everywhere, vehicular right of way seemed to be prioritised over the pedestrian right of way. This struck me as very strange, even as I continued to enjoy walking through lanes of Mumbai very much. On one hand, there is excellent footpath coverage, utilised by large crowds everywhere. On the other hand, speeding vehicles create obstacles for something as simple as crossing the road.  "Though Mumbai appeared to…
