Advantage of Rain Water Harvesting

Advantage of Rain Water Harvesting

Advantage of Rain Water Harvesting
• Rainwater can be utilized as natural resources.
• Ground water table can be increased particularly in the city area.
• Ground water potential and storage can be increased substantially.
• Bore wells and open wells of urban area can discharge sufficient yield.
• Ground water can be utilized as a water supply source during water scarcity.
• Major part of runoff is absorbed by constructed rain water harvesting pits which reduces the discharge flowing through existing runoff earning gutters and avoids over topping of existing gutters.
• Due to reduced runoff, the possibility of submergence of road and other structures lying at lower level of city are minimum, which reduces the possibility of settlement and wear and tear of roads and other structures.
• The water stored in harvesting pit can be utilized during water scarcity particularly in case of factories, and the production activities which could not be hampered.
• Re-circulation of rainwater is possible which maintains proper hydrological cycle, by maintaining proper infiltration rate, in city areas.
• In case of foundation of structures in black cotton soil, the presence of soil moisture can be reduced with constructed harvesting pit and avoids the waiting of building walls due to capillary action of water.
