What are the costs of constructing water harvesting facilities?
A.Water harvesting techniques are site specific and hence the cost of installation varies from place to place. Moreover the cost depends on the amount of water to be harvested. Typically, installing a water harvesting system in a building would cost between Rs 3,000 to 30,000 for buildings of total plot area of about 300 sq. m. Some basic rates of construction activities have been given on table given below which may be helpful in calculating the total cost of a structure. (If the rooftop rainwater outlets are widely scattered around the building, the amount of pipe required in connecting these outlets to the recharge or storage structure would be more. Thereby increasing the cost.) Table: Unit cost of construction activities.
