Water tankers being hijacked in Bangalore!

Water tankers being hijacked in Bangalore!

Do not be surprised if you read / hear this as headlines in your news.

Save Water Save Bangalore

Many citizens of Bangalore have not felt the heat of water crisis looming large in the next one or two months. No exaggeration. The water available in Cauvery river and the KRS dam is at its lowest in decades! Most of the borewells / tubewells have gone dry or are yielding very low water. 
New borewells are being drilled day in and day out, touching unheard of depths - 1000 feet and more.
However, we still see each day on the streets of Bangalore - 
Cars are being washed with hose pipes.
House fronts and roads being sprayed with water in buckets and hose pipes.
Overhead water tanks and underground sumps overflow with none paying heed. 
Are we blind to these acts?
Can we take the first step to stop these? 
Do we not have the social responsibility to save whatsoever available water, to conserve and share equitably among all sections of our society?

If not, WATER EMERGENCY may have to be declared???

Bengaluru Man Hasn't Paid Water Bill In 22 Years. Why That's A Good Thing
Bengaluru | Written by Maya Sharma | Updated: March 27, 2017 23:41 IST
 AR Shivakumar's house has a water storage capacity of 45,000 litres
BENGALURU:  The family of a senior scientist in Bengaluru has not paid their water bill for 22 years. Reason: AR Shivakumar is doing without a water connection, using treated rainwater not just for bathing and washing, but also for drinking. The senior scientist at Karnataka State Council for Science and Technology had designed his green home more than two decades ago - building in a water harvesting system that yields more than 400 litres of water daily. Which means the expected scanty rainfall this year - when the state is facing is second consecutive year of drought - will be enough for their needs.

"Bangalore receives around 900-1000mm of rainfall except for these very drought years," said Mr Shivakumar, whose work involves the field of renewable energy and rainwater harvesting. The amount, he says, is enough to collect 2.3 lakh litres of water a year. But 2.3 lakh liters is far more than an average family of four uses. Planned properly, tanks can be built into a standard 40/60 feet plot to store more than what a small family needs.

Explaining the rainfall pattern of the city, he said, there is 90-100 dry days between two successive rains in Bangalore. "Based on that calculation, we have a storage capacity for 45000 litres... effectively we need only around 40,000 litres - 400 liters a day for 100 days. But we have 45,000 litres for emergency."

AR Shivakumar had built his home over two decades ago
His family, he said, approximately uses 400 litres a day. "In a year, we need only 1 to 1.5 lakh litres, so much more than we require is coming here," he added.

The use of water, though, is careful, he said. Recycling plays a big part -- like collecting water from the kitchen sink in a can outside the kitchen to using water from the washing machine to flush toilets.

The water harvesting system is simple - water from the sloping roof is collected n underground tanks, where the purification process happens.

It is a family effort, said Mr Sivakumar - and his wife of 28 years, Suma, and his son, Anoop and daughter in law, Vamika, play their part as water conservation becomes a way of life for them.

Save Water Save Bangalore Campaign 2017

“Save Water Save Bengaluru” Campaign

The failure of rains in the monsoon and depleting water availability in KRS dam and also ground water in Bangalore may cause sevier water shortage in the summer months. Bangalore Water Supply and Sewerage Board (BWSSB) with the technical support of Karnataka State Council for Science and Technology (KSCST) initiated the programme to bring in awareness in Bangalore for water conservation to avert drinking water crisis in and around Bangalore.

Save Water Save Bengaluru” Campaign was flagged off on 22nd March 2017, Wednesday on the occasion of “World Water Day” at Vidhana Soudha, Bengaluru.

Honorable Chief Minister of Karnataka Sri Siddaramaiah with Minister Sri K. J .George, Sri Tushaar Girinath, IAS, Chairman, BWSSB, Sri Kemparamaiah, Engineer in Chief, BWSSB, Sri A.R. Shivakumar, PI, RWH, KSCST, IISc , Sri P. N. Ravindra, Additional Chief Engineer, New Initiatives and Public Outreach, BWSSB, Smt. P.G. R. Sindhia and others inaugurated the awareness campaign organized by BWSSB and Government of Karnataka. He also flagged off a 4 km rally to create awareness about water conservation.

Over 300 participated in the awareness campaign “Save Water Save Bengaluru”. BWSSB Team, KSCST Team, Scouts and Guides team, Children from various schools, NGOs, Press, and Media were present. Rally started at Vidhana Soudha and passed through K R Circle, K G road and successfully concluded at the Sewage Treatment Plant at Cubbon Park. A Street Play was also organized a performed by Abhinaya Taranga team.

KSCST provided technical support for educating NGOs and others to run the campaign till the end of May. To conserve water Sri A.R. Shivakumar suggested following three points for the city of Bengaluru and are being advocated by campaign partners:

“Save Water Save Bangalore” - YOU can do it....
1. Used Kitchen sink water can be reused for watering plants.
2. RO reject water can be as high as 70% which can be used for moping and cleaning the floor.
3. Toilet flushing requires 27% of your daily water need and washing machine discharges 22% of  
your daily water need. YOU can save at least 20% of fresh water daily.

Here's how Bengaluru can look beyond Cauvery for water

Here's how Bengaluru can look beyond Cauvery for water

Thippagondanahalli Dam (EPS | S Manjunth)

BENGALURU: Bengaluru is once again facing the prospect of shortage of drinking water, highlighting our heavy dependence on Cauvery river water for drinking. Amidst the emotional scenes witnessed over the past few days over sharing of Cauvery waters, is our own unwillingness to adopt even minimal measures to conserve and recycle water.
At present, Bengaluru requires 1,450 million litres per day (mld) and about 19 tmcft of water per year from Cauvery alone. As population expands, it is difficult to sustain drinking water supply to the city, which is already facing a shortfall.
It is estimated that Bengaluru has the potential to harness 22 tmcft per year from its sewage and storm water drains. Every water conservation technique that is implemented can cut down the use of piped water considerably. 
“Any city, in the future, cannot depend on rivers or dams alone for water supply. There has to be better planning. About 50 per cent of it can come from dams and rivers, 20 per cent from rain water harvesting (RWH), 20 per cent from recharged borewells and 10 per cent should be recycled water. This is the only way we can sustain our supply,” says A R Shivakumar, a scientist at the Karnataka State council for Science and Technology at the Indian Institute of Science.
Despite Bangalore Water Supply and Sewerage Board (BWSSB) making it mandatory for building constructed in 30x40ft and bigger dimension sites to have RWH mechanisms,  there are only a few takers. Also, there has been no punitive action against those who have failed to implement it.
Shivakumar says that around 1,00,000 homes in Bengaluru have adopted RWH. “It is not a big number compared to more than 20 lakh properties in Bengaluru. But it is a good effort and hopefully will catch on,” he said.
Water recycling in bigger complexes is now catching up in new buildings, but the old ones are hesitant. Recycled water can be used for secondary purposes like gardens, construction and washing vehicles. “A place like Cubbon Park has a state-of-the-art recycling plant and the water is used for gardens. The results are there for all to see. It will not hurt the government to set up treatment plants to recycle the waste generated around its office buildings like M S Building and Vidhana Soudha. This sets a good example and will encourage people to follow suit,” Shivakumar said.
He also blames the unaccounted water that comes via pipelines and then just disappears. According to BWSSB’s own admission, these losses are between 40-45 per cent. “Norms specify that these losses should be around 15 per cent. But, despite the civic agency’s best efforts, these levels have not fallen to below 40 per cent,” says former Chief Secretary A Ravindra.
He also said that protection of groundwater resources is one of the major tasks to be undertaken to improve the situation in the city.
“RWH needs more compliance. The government can also encourage people by constructing large ponds to collect rainwater. Restoration of tanks and lakes and groundwater recharging can help meet the drinking needs of the population to a large extent,” he adds.
Message on BWSSB website
A message on BWSSB website reads: “Since there have been drought conditions prevailing in Cauvery basin which have resulted in minimal flow into the reservoirs in the month of August and September, enough Cauvery water may not be available in the coming months. As the rainfall prediction is meager, the BWSSB requests all its consumers to consume and use water judiciously.”
5 ways to save water
Water conservation experts say that by following these simple steps, the city can save a lot of water over time
Rainwater Harvesting
It could be as simple as placing a bucket below the pipe that channels the rainwater in your house, but BWSSB rules make it a little more comprehensive and mandatory. It is the simplest and most essential form of conservation residents can adopt and works on the premise that there should be 20 litres or more tank capacity per square metre of roof area. Unfortunately, at present, there are only an estimated 1 lakh homes which have implemented this but wider application can easily solve our water woes. We can save around 23 tmcft per year this way.
Recharging lakes and groundwater
Recharging lakes is a crucial component of ensuring self-reliance in terms of water supply. Not only do we manage to fill our lakes, but we can also recharge the groundwater and aquifers. However, the city’s lakes are composed of silt consisting of sewage, waste chemicals, organic waste, dead vegetation and heavy metals turning the bottom of the lake into a cement-like impermeable layer. Even if the water permeates, it will poison the underground water table. Stopping sewage inflow into lakes and clearing out catchment areas is very essential.
Sewage Treatment Plants
Almost every lake in the city has copious amounts of sewage flowing into them, turning them into a frothy nightmare. Not only are STPs necessary to stop this, they can be adopted on a smaller scale in apartments, commercial and government buildings. Even if people are not comfortable using this recycled water for domestic purposes, there are plenty of uses like watering gardens, washing vehicles and reusing them for flushing toilets.
Unaccounted losses
According to BWSSB, around 40-45 per cent of the Cauvery water is lost and pegged as ‘unaccountable losses’. That is around 650 mld. The water lost due to leakage in pipes is negligible. Most of this water is pilfered, which means illegal water connections are drawn right from localities to large industries and hotels. Efforts to control this form of losses are lukewarm. Politicians do not want to upset their vote banks and only strong political will can bring this under control.
Tariffs and incentives
At the lowest slab, water supply from BWSSB means that a house gets 1,000 litres of water for a measly `8. The higher slabs are not much of a deterrent either. An expert on water conservation techniques says that the government should take the bold step of providing around 10,000 litres per month (going by WHO’s recommendation of 100 litres/person/day) at a low rate and then hike the tariffs exorbitantly. That would make everyone sit up and take notice and consequently choose water conservation methods to avoid paying a higher tariff.

ARS @ TEDx Bangalore on 16th July 2016

AR Shivakumar @ TEDx Bangalore on 16th July 2016

Water is one of the most important components of all living beings.
We use around 100 to 150 litre per person per day directly.
Virtual use is as high as 11,500 litre per day per person - 37 lt for 1 lt milk, 2500 lt for 1kg sugar, 100 lt for 1 unit of electricity....which looks scary..

I do not buy the statement that there is water scarcity in this world.
There is plenty of water to fulfil all needs, not only human but for all other living creatures on this earth. Unfortunately we have not been able to keep up a sustainable and equitable distribution of clean and safe water for all.
We moved from decentralised and sustainable to centralised and unsustainable and may be to -water as a commodity..
Water on this earth has remained same in quantity for ages - not a drop less not a drop more. Water we use is the same water molecules what dinosaurs drank. water cannot be manufactured nor destroyed. Can anyone destroy a drop of water or bring a fresh drop of water to this earth - NO. Have you heard of a factory or a mill to produce water anywhere in the world.

Water is a wonder fluid which occurs naturally and rain is our only source for purest form of water. All other source / forms of water are derived from rainwater.
Living with nature and making nature to work overtime for you - not to abuse
All our needs can be met from the gifts of nature around us

Here is an example - doable and also sustainable:
Sourabha my house in Vijayanagar, Bangalore derives most of the daily needs from nature. Built during 1994, has sustained by harvesting rainwater for all our needs including drinking water for over 20 ecofriendly years. We do not have city - BWSSB water pipe connection to our house, we have not paid a rupee water bill in the last 20 years.
Rainwater from the roof of our house is filtered at four locations and stored at various levels in tanks and underground sumps. We have 45,000 litre total storage capacity and we use around 400 litre per day for our family. Studying 100 years daily rainfall data, I found out Bangalore has only around 100 dry days between two good successive rains. For 100 days 400x100=40,000 litre is good enough and we have 5,000 lt extra making it 45,000 lt storage of rainwater. In a plot of 2400 sqft (40ftX60ft) around 2,20,000 litre can be harvested in Bangalore. Around 1,50,000 lt is harvested from roof for storing and the rest is recharged in to the ground for a social cause. This way not a drop of rainwater flows out of Sourabha.
Though we have plenty, we reuse used water in our house - washing machine discharge soap/detergent water is used to flush toilets, kitchen wash water is used for watering plants and trees around the house, plants are healthier with vitamins and mineral rich organic kitchen used water. Around 20 to 30% of water is reused each day.
All organic waste is treated on site - earthworms convert all the organic garbage into manure  for hundreds of plants and trees around Sourabha. We have not contributed to the city garbage collection other than recyclables and rejects like plastics, glass bottles and metal cans.
Tons and tons of organic garbage for years is now beautiful green plants and trees around the house. Fresh and clean air encapsulates our house and also keeps the environment cool. We do not use air conditioners nor fans even in deep summer (except rooms on first floor). The green curtain of plants and trees not only provide fresh and clean air but also home to number of chirping birds, colourful butterflies, insects, bees and many more. Sourabha looks like their home and we are guests of nature inside Sourabha.
Sun is the provider of energy through solar water heater, solar electricity for lighting and natural light through sky lights.
Rattrap design of walls to keep the house thermally insulated, bright whit painted roof to reflect solar radiation and keep the house cool, water bodies around the house to add moisture to the air and also home for aquatic life like lotus, fish, turtles and many more. Water bodies on the roof as bird bath and to provide water to a number of birds. Coconut husk and shell as pots for plants and many orchids. A micro environment to fill nature to our life at Sourabha in the central district of Bangalore city.

These are doable and simple concepts for each one of us to adopt.

The bottom line for a nature friendly sustainable living in an urban environment - 400 lt of water per day per family, around 100 units of electricity per month to fulfil all our luxury, one gas cylinder to support cooking for 75 days and most important only 2.5 kg of dry / recyclable waste per WEEK.
Several of these water conservation and rainwater harvesting concepts are now policy guidelines provided from my organisation KSCST at Indian Institute of Science and are being implemented by the Government for a better tomorrow. Two help desks, one at IISc campus and other at Jayanagar 5th block supported by BWSSB are providing training, awareness and consultation for individuals, institutions and corporate houses.

Hundred thousand Bangalurians are harvesting RAINWATER, why not you?
