Why BWSSB’s notification on STPs is illegal, impractical and illogical

Residents of many old apartments in Bengaluru were shocked to see a notice that asked them to install sewage treatment plants. Bengaluru Apartments Federation calls it completely illogical. Here's why.

The Bangalore Water Supply and Sewerage Board (BWSSB) issued a notification in March 2016, mandating apartment complexes with 20 units or more, to install Sewage Treatment Plants (STPs) and dual-piping with retrospective effect. The absurdity of the notification can be summarised with three ‘I’s – it is illegal, impractical and illogical!

Why is it illegal?

Firstly, all the enforcement authorities like Central Pollution Control Board (CPCB), Karnataka State Pollution Control Board (KSPCB) and Ministry of Environment have directed BWSSB to mandate new apartments with 50 units and more to implement STP with prospective effect.

But the BWSSB has chosen to ignore the directives and taken a unilateral decision on retrospective application, which is in violation of its own Act under which it has been constituted. Section 122(2) of the BWSSB Act states that any rule with retrospective effect can be made only after the reasons for the same are laid down before both Houses of the State Legislature and an approval is obtained. In the absence of the above, the notification is completely illegal.

Why is it impractical?

Apartments constructed in 1970s, 80s and 90s are not likely to have the right kind of space alignment required to retrofit a STP. Digging the ground near the foundation pillars to construct STP and breaking open walls for a dual-piping might compromise the safety of the buildings.

A properly-designed and constructed STP, together with dual-piping, for a 150-apartment complex would cost over Rs 1.25 crore. This would need an upfront investment of Rs 80,000 per apartment unit together with a running cost of about Rs 800 per month. Most of the older apartments would have elderly residents. They would have very likely invested their life’s savings to buy the apartment and may not be in a position to afford this extra burden.

Finally, the city already has many STPs many of which are dysfunctional or semi-functional, including BWSSB’s own STPs, owing to limited available technical expertise, ineffective guidelines, impracticality of enforcing compliance on thousands of STPs etc. The addition of a few more thousand STPs with retrospective effect is a perfect recipe for an environmental disaster.

Why is it illogical?

Old apartments are not causing any lake or water pollution separately, since they are already connected to the underground sewage drain (UGD) provided by BWSSB. In addition, old apartments might not be able to reuse much of the waste water, unlike newer apartments, so bulk of the treated water has to be let out into the UGD or storm water drain. This just does not make any sense since BWSSB has centralised STPs that are connected to the UGDs to treat the sewage. The retrospective implementation just does not serve any purpose.

The directives from CPCB and KSPCB have not been about retrospective STPs. Instead, they have directed BWSSB to provide UGD to cover the entire urban area of Bengaluru and then treat and dispose the sewage safely. But then, doing that probably means getting work done which must be a lot of effort. Passing absurd notifications asking citizens to do BWSSB’s job must be a lot easier!

In a nutshell, BWSSB has passed a notification beyond its constitutional purview asking residents of old apartments to find space where none exists, find huge amounts of money which they don’t have, put their buildings to risk which is probably the only asset they own, to implement thousands of STPs which could be a huge environmental hazard, for something that is not going to address either the lake pollution issue or water availability!

It is time for apartment residents to unite and fight these illogical and unreasonable demands thrust on them continuously by civic agencies!

Srikanth Narasimhan is General Secretary of Bangalore Apartments’ Federation (BAF). BAF represents the interest of apartment residents & is also trying to find reasonable solutions to the city’s problems.

Study shows TNPCB ill-equipped to monitor the environmental impact of pollution

The scientific team of TNPCB is working at half its strength, affecting the Board's ability to carry out inspections in Chennai and other parts of the State.

The Central Pollution Control Board and the State Pollution Control Boards are the primary custodians for preventing and controlling all forms of pollution in our country. Despite their significant role in environmental protection, the public is mostly unaware of the functions of these regulatory bodies, due to insufficient research. Therefore, we at Citizen consumer & civic Action Group (CAG) have attempted to understand the functions of the Tamil Nadu Pollution Control Board (TNPCB), through a study titled ‘The Tamil Nadu Pollution Control Board in Retrospect: An Examination of Selected Parameters from 2017 to 2022.’ Read more: Fisherfolk lament as environmental…

Why the national programme for clean air failed a gasping Mumbai

Mumbai has seen an alarming decline in air quality. A look at the limited impact of the National Clean Air Programme on mitigating pollution.

October 2023 was a shocker for Mumbai. The coastal city has historically recorded lower AQI levels as compared to Delhi, which is notorious for its poor air quality. But the tables turned in October 2023, with AQI in Mumbai reaching dangerously high levels of up to 300, surpassing Delhi for several days. This led to a slew of respiratory ailments, more so among the vulnerable populations. PM2.5 levels have, in fact, seen a consistent increase in Mumbai over the past three years. Dr Jui Mandke, a paediatric surgeon practising in Mumbai, says, “In October 2023, we encountered the maximum number…
