apartment water management

Two years ago, Sobha Daffodils -- an apartment in HSR Layout -- decided to do something about their water footprint. Over 420 houses in the apartment adopted smart water flow meters that monitor water usage in real-time. Since then, Radhakrishna Kurup’s average water intake has dropped by about 20%. Kurup is the President of Sobha Daffodils Apartment Owners’ Association. The use of water globally has increased by roughly six times over the past 100 years, and is expected to rise further. The available freshwater resources have declined by more than 20% per person over the past two decades, according to…

Apartment residents often are unaware of how much water they consume in their household. A common water meter installed by the BWSSB (Bangalore Water Supply and Sewerage Board) measures consumption of the entire apartment complex, but not of individual flats. The monthly water bill based on this meter is usually split evenly among all residents. But, in May 2020, BWSSB introduced a new regulation that mandates internal water meters for every flat in apartment complexes. Each apartment is responsible for installing these meters within their premises. Individual water meters compulsory, but no penalty yet According to the new regulation 43-A…

In the past few years, most borewells in our apartment The Greens had gone dry due to depleting groundwater levels. We are a 10-year-old apartment community in east Bengaluru, off Outer Ring Road, with 171 flats spread across four blocks. We also have a swimming pool, a small clubhouse and a gym. Our water expenses had skyrocketed, and we had to increase our maintenance charges regularly to cover the cost. So in early 2018, we implemented three measures - water metering, reusing treated water, and rainwater harvesting (RWH) - to reduce our water use. The outcome was that our water…

Bengaluru is rapidly losing its groundwater. The city’s water bodies have shrunk, to give way to buildings and infrastructure projects. Come summer and Bengalureans can be seen obsessively discussing water, or rather the lack of it. Though rains bring momentary relief, what about the long-term demand? Access to water is a human right - how can we provide every citizen with enough water for their needs, at a price they can afford? Little has been done to find local solutions. Rainwater harvesting had been implemented in just 1.2 lakh buildings as of May 2019, according to the BWSSB. Meanwhile, big…

This summer, Bengalureans faced another gruelling water crisis. So much so that residents even in core areas of the city had to start buying water from private tankers. And in outer areas, even private tanker supply was inadequate. We had earlier published a guide on building recharge wells to capture rainwater this monsoon. Another way to meet your water requirement is by treating and reusing the greywater generated in your household, especially if you live in an independent house. What is greywater? Greywater is simply soap water; it's the wastewater from bathrooms, washing machines etc. Greywater does not contain much…

The Karnataka State Pollution Control Board (KSPCB) has been serving illegal notices to apartment residents, threatening to disconnect electricity and water, with the malafide intent of extortion by corrupt officials, says a press note from Bangalore Apartment Federation (BAF). Apartment associations are reportedly refusing to bribe the officials who want to “settle” matters, and have joined hands under the aegis of Bangalore Apartments’ Federation (BAF) to fight against these unlawful and malafide practices, informs the notice. The KSPCB notices cite conditions which are completely against the rules laid down by the Central Pollution Control Board (CPCB) and Ministry of Environment…

Three communities in southeast Bengaluru - Rainbow Drive, Adarsh Palm Retreat and Renuka School adjacent to Kaikondarahalli Lake, have created individualised water management plans to solve problems like water shortage, reliance on borewells and flooding. Knowledge and understanding of their groundwater system has allowed these communities to make smarter decisions when it comes to withdrawing groundwater and making the conscious effort to recharge water back into the earth. Biome Environmental Trust, ACWADAM and Mapunity with funding from Wipro Ltd. spent three years researching the water that lies beneath the surface in a research project called Participatory Aquifer Mapping (PAQM). An…

Tariffs are the single most important economic tool to control individual resident’s water usage. Many apartments often bundle water charges into a single maintenance account. But this keeps the expense of water consumption invisible. RWAs must have a Cost Account for water separately. RWA Management Committees need to consider various parameters to arrive at the tariff. What cannot be measured cannot be managed. The first step is to measure water consumption and calculate the total cost for getting water into a resident's flat.

We all depend on groundwater. The single largest source of water that Bangalore has created apart from Cauvery, is actually a hole in the ground! We are pulling water that has been down there for hundreds of years, that is somebody else's right as much as it is ours. Some use Cauvery water or groundwater to flush the toilets, while some others are not getting water even to drink. Where does ground water come from? We all live above common aquifers – spaces between soil particles and cracks, fissures and faults in the rocks. The spread of aquifer is independant…
