In part-2 of “Does Bangalore face Waterless Future” series presented by ApnaComplex, Mr. S.S.Ranganathan elaborates on ‘REDUCE’ part of his ‘mantra’ – REDUCE, REUSE and RECYCLE. He goes on to recommend installation of water meters for every flat/villa in a gated community based on his studies/experience. Read “Does Bagalore face Waterless Future? Part – 1”
This refers to current water consumption which needs to be monitored carefully so that it can be reduced. Water consumption guidelines are laid down by the CPHEEO (Central Public Health Engineering & Environmental Organisation) which is a central govt.organisation is as given below:
How much water does a person need per day?
This is the suggested quota applicable to urban areas, while the quota applicable to the 4 metros is 150 litres. Litres used per person per day is known as “ litres per capita daily”(lpcd). I can say that it is possible to live with a quota of even 90 lpcd ( I have tried it out myself).
First measure your consumption
I have worked with a few RWAs who wanted to monitor water consumption and were willing to spend money to get some realistic data. The results showed that the actual consumption was anywhere between 200 to 450 lpcd!! Another interesting figure that became clear when doing these studies was that approximately 20 to 30% of the homes accounted for almost 80% of the consumption. Currently, RWAs charge each flat an amount for water useage which is simply total water useage & cost divided by number of apartments. In this situation, it is the careful, frugal users of water who subsidise the heavy users of water. This has lead to unpleasant confrontations amongst residents and created the awareness that water consumption to each and every apartment/villa must be monitored by installing a water meter for each flat and apartment.
By installing Water Meters, association can mandate charges to be collected on actual useage using a slabwise tariff which makes it very expensive for users of large volumes (in fact such charges should be punitive and thereby penalise profligacy in water use). Single homes like the one I live in who get Cauvery water from BWSSB which gives a water connection through a water meter. Users have to pay for every 1000 litres of water consumed slabwise. Depending on the slab the rate per 1000 litres doubles and triples as the slab goes up. It is therefore highly essential that apartments spend the money that will be needed to meter the water supplied to each apartment. Better still, the state government should enact laws which make it compulsory for builders to design and install plumbing to supply water to every apartment with a single water meter.
I have on occasion given presentations on the water situation to certain RWAs who wanted to create awareness on water amongst their residents. After such presentations there is usually a question from some economically well off persons saying that they are prepared to any price to get water, but my reply has always been that such individuals are in a minority and that when the water crunch hits the city, water will not be available for love or money, so, once again I urge residents of this city to REDUCE their usage of water.
