T.A.P Water

Water Conditions of Mumbai
Water is one of the most vital natural resources for all life on Earth. The availability and quality of water always have played an important part in determining not only where people can live, but also their quality of life. Even though there always has been plenty of fresh water on Earth, water has not always been available when and where it is needed, nor is it always of suitable quality for all uses. Water must be considered as a finite resource that has limits and boundaries to its availability and suitability for use.  Water is needed for various domestic as well as industrial purposes.  We use water for drinking, washing, cleaning, cooking, and farming, etc. Various agricultural as well as industrial processes like steel production require water at large amount. Electricity production, transportation also requires water in a considerable amount.
The balance between supply and demand for water is a delicate one. The amount of water in hand and in future will keep on depleting as the development proceeds. Water must be in sufficient supply for an area to develop.  
Mumbai receives its demand of water from various dams. Western Ghats traps most of the moisture and feed to these dammed rivers.
 Currently, these dams deliver approximately 3.4 billion litres of water to Mumbai daily. There are seven lakes that provide water to the population of Mumbai includes Bhatsa, Upper Vaitarna, Middle Vaitarana, Modak sagar, Tansa, Vihar and Tulsi. Mumbai city requires 4200 million litres of water daily. Mumbai municipality (BMC) supplies only 3500 to 3750 million litters of water per day. The gap between demand and supply is met by tankers, wells, bore wells, rain water harvesting, etc.
We have taken water for granted because it is normally available to us all the time. So people are using it very carelessly. With only 3% being available for drinking, wasting this precious resource has become a very careless & contagious habit leading us to a platform where we even lose its sight
Washing a car is more like a routine activity for all city folks. Water used for washing 1 car daily wastes approximately 302.83 litres of water per month. Swimming in the swimming pool takes 1000 gallons of water at a month. This water is too precious for our environment. Dish washing, sprinklers and fountains also waste large amount of water. Use of the flush in toilets takes 37.85 litres of water per flush which is not required. Use of the shower for bathing uses 1/5th amount of water which is required for bath. Leaky taps and faucets contribute to water wastage. According to BMC’s Rain Water Harvesting Cell leaving the tap water running results in wastage of 198.75 million litres per day.
Population of India is increasing at an alarming rate. As per 2001 census Mumbai has 11.98 million populations. Population graphs are continuously showing increase and this will lead to increased water demand. According to statistical data it is estimated that 6326 million litres per day water is needed to fulfil need of water upto 2050. As the resource is getting scarce there is ultimate need to store it and use wisely and also tap techniques of grey water recycling.
Why are we discussing all these stats on water in Mumbai? Stay tuned for more....
