Tankers and life - water woes in bangalore


If you do not pay attention to the water problem now, you would have to survive on water tankers and God knows where they get their water from and how.  The other alternative is to opt for the Samskruti Way and don't depend on bore wells, tankers and Cauvery water but build systems to store, purify and use rainwater and focus on recycling grey and black water. 
Prashanth G N's article in Deccan Herald shares the growing problem in Bangalore. Read on. 

One of the most crucial factors to consider while buying a house should be the availability of water, writes Prashanth G N

Availability of water is the most crucial factor while deciding to buy a home — be it an independent house or an apartment. South Bangalore, ironically, is the most vulnerable region to water shortage despite the Cauvery River being closest to it. Scores of residents in and around J P Nagar 8th Phase and Sarjapur are put into hardship because they have no Cauvery connection or even borewells.

In general, with no option left, people continue to stay where they are and even go to areas where houses are being built with no guarantee of water. The need to have a permanent house in Bangalore is very crucial and hence people are willing to take houses wherever they are allotted, even if it means facing acute water shortage.

Industrialist and a resident of J P Nagar 8th phase, B Y Ramesh says, “We live in an independent house in T K Deepak Layout in J P Nagar 8th Phase. And our house is just 500 metres from the Cauvery water pipeline, but we still have no Cauvery connection and we don’t get a drop of water despite the water line running so close. On top of this, borewells have gone dry. So we have to depend on water tankers, which have become our lifeline.”

Ramesh’s family needs a water tanker every three days. “When the tank is 3/4th empty, we seek a tanker, which on average works out to every three days. Over a month, we roughly need 10 tankers. Each time we get a tanker, we pay Rs 350. The water that we and our tenants consume amounts to about 3,000-4,000 litres.” 
The absence of water is not just Ramesh’s plight, but of almost all the houses in Deepak Colony of J P Nagar 8th Phase.

You ask people in the area as to why there is no connection, they tell you the reason is obvious: “People in the middle have to be paid the moolah and since it is for the whole layout, the money to be handed out would be high. Otherwise, how can you explain why we don’t have the Cauvery water connection when the water line runs just 500 metres from our houses. We don’t think it’s a technical issue. It’s a ‘financial’ issue,” say the residents.

Nagaraj Reddy of the Confederation of Real Estate Developers Association of India (Credai) says Bangalore South is one region hit by water problems despite the Cauvery pipeline running in the area. “Bangalore North anyway doesn’t have the Cauvery pipeline coming into the region, but in the South, there are some regions which get water and some regions which don’t.”

South Bangalore is typically identified with Jayanagar and J P Nagar, but when you take into account the entire region up to Kanakapura and Marathahalli, the belt falls under the southern region. And the worst area hit by lack of water is Sarjapur, home to WIPRO. There are hundreds of flats and gated communities in the area which depend on water tankers because borewells are dry and there’s no Cauvery connection.

A resident of Sarjapur area, Shravanthi S, says the region they are staying in is a rocky terrain where borewells cannot be dug. A cluster of apartments around 500 depend purely on water tankers and the number is nearly 70 to 80.

There is yet another cluster of over 1,000 apartments which depend on water tankers. The average rate of water is higher than in J P Nagar with tankers charging anywhere from Rs 450 to Rs 600, resulting in a spending of over Rs 3,000 to Rs 5,000 per month by an average four- member family.

While the crisis with regard to apartments has been highlighted well, the water shortage for independent houses is also severe and has not received due attention. A youngster, Anurag Rakesh, answers to why his family is still staying in J P Nagar despite water shortage, “This is our own house. How can we sell it?”. Further adding, he says, “ We will stay here till we can afford this. The water problem may get addressed soon.”

Tanker mafia

Shravanthi points to a very deep malaise in Sarjapur. “My assessment is that the water tanker owners pay off the corporators to pile pressure on the BWSSB not to provide Cauvery water supply to residents. This increases dependence on tankers, who make a killing selling water. In our complex, we need 20 tankers a day. But in the heart of summer, an artificial scarcity is created and we now get only five tankers a day. There are blocks a little away from my complex which require 50 to 70 tankers a day. You can estimate the money that is flowing into the pockets of tanker owners.”

“There is actually a tanker mafia in operation. They pay the water owner a sum, who may be a farmer. They then draw water, fill tankers and supply the same to residents. Nobody knows how much they pay the farmer who has water. There is also no guarantee that the tankers will keep coming. So there are plenty of issues with water in Sarjapur area.”

Water problems!

DNA: Healthy pre-monsoon trends have indicated that Bangalore will have a good monsoon.

The city is expected to get more rain in the days to come, as part of the pre-monsoon showers before monsoon hits the city. Strong winds, an upper-air cyclonic circulation coupled with a low pressure area in the Arabian Sea, has set the perfect tempo for the monsoon to arrive in the city.

Speaking to dna, an official from the Bangalore meteorological centre said the city has had 89mm of rain so far in the pre-monsoon season and that another 29mm of rain is expected in the coming days.

“Bangalore’s normal pre-monsoon rainfall is expected at 118mm. We have had healthy pre-monsoon season and it has cooled the city sufficiently,” the official said.

The city is expected to receive 110mm of rainfall in May alone.

“This is because, as we approach monsoons, the pre-monsoon activity goes up and then dips. This is a regular phenomenon,” he said.

The Southwest monsoon is expected to be about three days late this year.

“Usually, monsoon hits the Kerala coast on June 1, but this year, the meteorology department has declared that it will arrive on June 3. All climatic conditions are healthy and monsoon should hit the city by June 7,” he said.

The temperature is also expected to go up by two degrees according to the department officials. “By the end of the month, we are expecting the temperatures to go up to 36° C,” he said.

Things are looking better on the water front, as the scenario  might improve in the coming days. Rain is expected to be normal in the catchment areas of the Cauvery, which supplies water to the city.

Normally, from March 1 to May 15, Mandya, where Krishnaraja Sagar is located, is expected to receive 99mm of rain, but it has already received 101mm.

In Kodagu, which is the upstream area for Cauvery river, there has been near-normal rainfall, and although the average pre-monsoon rain in this catchment area is 171mm and has received just 141mm so far, the met officials are confident of more rain in the coming days.

Bangalore & Rain Water Harvesting

According to a study conducted by the Centre for Symbiosis of Technology, Environment and Management (STEM), a Bangalore based research group, the demand supply gap is met by groundwater exploitation. It is estimated that 40 per cent of the population is dependent on groundwater, whereas the remaining part is pumped from the Cauvery river through a distance of 95 kilometres and a head of 1000 metres.

Bangalore receives 970 mm rainfall annually and the number of rainy days is 59.8. Highest amount of rainfall is received during April to November, while the rest of the months receive scanty rainfall. Peak runoff is 50 millimeters per hour. Due to the availability of rainwater throughout the year, water is basically stored in these rainwater harvesting systems and used for non-potable purposes. Water from the rooftops is led into storage structures. First flushing is normally done by providing an extra length of pipe to collect the polluted 2.5 mm of rainfall. Filters are made of sponge and a mixture of sand, gravel and charcoal. After first flushing and filtration water is led into under ground sumps (which are very common in Bangalore) or to a new storage tank.

The overflow from this tank is taken to an open well to recharge the aquifer.The geological formations are predominantly granite and granitic gneiss, with joints and fractures in abundance due to intense chemical weathering of rocks. The depth of weathering varies from 0.2 m to 20 m. This geological set-up offers an immense scope for recharging of ground aquifers.

The undulating terrain with gentle slopes draining into lakes offer an ideal situation for water harvesting. In the urban area of Bangalore waterbodies cover about 5 per cent of land. A study made by the Centre for Ecological Studies and Indian Institute of Sciences revealed that out of 262 lakes in 1960 only 82 exist now of which less than 10 have water.
