Water Supply

Recently the State Pollution Control Board (KSPCB) slapped heavy fines on multiple apartments in the city. The reason: "STP is not running properly", "treated sewage does not meet some quality parameters". Some apartments have rightly questioned KSPCB's sampling method, the inordinate delay in sending test reports, and the fact that the apartments' own monthly tests (conducted at NABL-accredited labs) had never shown any problem with the treated water quality. While these objections are valid, the ugly truth is that many STPs may really be unable to treat sewage fully. In a previous article, I explored why this happens, and how some reforms…

Today, a large number of apartment complexes, malls and tech parks in Bengaluru have their own STPs (Sewage Treatment Plants). If an STP is working properly, its treated water would look just like tap water - clear, without any odour. In addition, it must meet the specifications set by the State Pollution Control Board (KSPCB). If the treated water looks dark brown, or stinks, the STP owner knows that the STP has some trouble. But even if the treated water looks clear and odour-free, it may still not meet specifications; and the owner may not be even aware that his STP…

Translated by Sandhya Raju 2019-ம் ஆண்டில் ஏற்பட்ட கடுமையான தண்ணீர் பிரச்சனையை தொடர்ந்து சென்னை பெருநகர  குடிநீர் மற்றும் கழிவுநீர் வாரியம் (CMWSSB) சில இலக்குகளை வெளியிட்டுள்ளது. இது நிறைவேறினால் நம் நகரம் தண்ணீர் பாதுகாப்பு உறுதி பெறும். இது வரை முற்றிலும் தண்ணீர் வசதி பெறாத பகுதிகளுக்கும் , போதிய அளவு தண்ணீர் பெறாமல் இருந்த பகுதிகளுக்கும் இந்த ஆண்டு குடிநீர் வாரியம் தனது சேவையை அளிக்க உள்ளது. இதனுடன் கீழ்கண்ட முயற்சிகளையும் முன்னெடுக்க உள்ளது: 1. கழிவு நீர் மறுசுழற்சி நகரத்தில் அதிகரித்து வரும் தண்ணீர் தேவையை பூர்த்தி செய்ய, கழிவுநீர் சுத்திகரிப்பு நிலையங்களை அதிகரிக்க குடிநீர் வாரியம் திட்டமிட்டுள்ளது. கொடுங்கையூர் மற்றும் கோயம்பேட்டில், ரிவர்ஸ் ஆஸ்மோசிஸ் சுழற்சி முறையில் இரண்டு சுத்திகரிப்பு நிலையங்கள் தற்போது உள்ளன. இவை தலா 45 mld அளவு நீரை தருகின்றன. அருகில் உள்ள தொழிற்சாலைகளுக்கு இந்த நீர் பயன்படுத்தப்படுகின்றன. இதன்…

Chennai’s water security has been a hotly debated issue, ever since the city saw alternating incidents of devastating drought and destructive floods over the last five years. The floods were the result of thoughtless urbanisation while the drought came about due to the city’s poor adoption of water conservation. An answer to the conundrums surrounding water in Chennai may well lie in turning towards nature-based solutions, according to the proposals put forth by a promising initiative titled City of 1000 Tanks. City of 1000 Tanks is a multi-stakeholder effort, including the Corporation of Chennai and 100 Resilient Cities, that involves…

As the rejuvenation of Bellandur and Varthur lakes is underway, the NGO Bangalore Environment Trust (BET) has written an open letter to the state government, requesting course correction. The expert committee on lake rejuvenation had recommended that both the lakes be desilted, but BET's letter points out that it'd take 53 years to remove the toxic silt-cum-slush in Bellandur lakebed, and 20 years for Varthur lakebed! This is because toxic waste has flown into the two lakes, unimpeded, for the last 50 years. BET's calculations are based on a recent study by the Indian Institute of Science (IISc). More importantly, the…

This article is part of our special series on Delhi Elections 2020 Round the clock supply of clean drinking water and continuation of the free 20,000 litres per month water consumption per household that is currently in place, comes second (only after Jagmag Delhi -- subsidy on power bills) in Delhi chief minister and Aam Aadmi Party chief Arvind Kejriwal’s list of 10 “Guarantees” to the people of Delhi if they return him to power. Supplying free water, especially to areas that had no water supply, was one of AAP’s key promises when the party made its foray into electoral politics.…

In view of the severe water crisis that gripped Chennai in 2019, the Chennai Metropolitan Water Supply & Sewerage Board (CMWSSB or Metro Water, in short) has unveiled a set of goals for 2020, which if met could help make the city water secure. The agency plans to extend its services to the underserved and unserved areas in the city this year, and ensure the following: 1. Reuse of Waste Water In order to meet the growing water needs of the city, Metro Water plans to expand the number of wastewater treatment facilities in Chennai. The city has seen two…

Chennai found itself in the grip of an acute water crisis last summer. The city saw a deficit monsoon the previous year and the reservoirs had all but run dry. Thus began a period of acute hardship for Chennaiites that lasted months. Long queues for tanker lorries across neighbourhoods became a common sight. Families survived on a mere three pots of water a day and women bore the brunt of the crisis, having to forego time at work or school to gather water. The crisis was however not without warning. Signs of scarcity had been looming for a while, but little…

Urban growth and expansion of cities is increasing the demand for land and water, increasing pressure on resources available not only in urban, but also in peri-urban areas. State policies often use peri-urban spaces and resources to meet the needs of urban populations; for instance, they use grazing lands for urban infrastructure, sewerage and water treatment plants or for special economic zones. Water is another resource that continues to be scarce in urban areas because of the growing population and competing domestic and industrial water needs. Public infrastructure and utility services are unable to keep pace with the growing water…

Pune’s No 1 ranking in the Ease of Living index contrasts sharply with ground realities, especially when one considers the most basic requirement of all, water. Despite recording one of its heaviest rainfalls this season (561.8 mm, according to Dr Anupam Kashyapi, Head, Weather & Air Pollution Monitoring Unit, India Meteorological Department), and the district’s four dams -- Khadakwasla, Panshet, Varasgaon, and Temghar -- being nearly full, the city is facing a shortage of water and inequitable supply. “In our area, we have seen flooding in some societies while we queue up for drinking water”, said a distraught Arvind Vichare…
