Agar Nullah, which flows closely on southern side of the proposed site of this Colony, has much grater perennial flow to meet relatively meagre water demand of this Colony i.e. 65, 000 gallons per day. Incidentally it was a rainy day and water was too turbid on 20-02-2009 when water sample from flow of Agar Nullah was collected, which shows turbidity of 295 PPM Silica Units or N.T. U, refer Chemical Analysis Report of water collected from Agar Nullah at Annexure-III. This turbidity in surface water of Agar Nullah during moderate rains on 20-02-2009 will increase many folds during heavy Monsoon and winter torrential rains requiring a costly water treatment before supply for human consumption. This water source is, therefore, not considered to be suitable and cost-effective.
