Rainwater Harvesting Seminar and PPT with pdf report: Our earth is covered with 75% of water and 25% of land but water scarcity is a global. This is to certify that the Project Report entitled “RAINWATER HARVESTING AT. NATIONAL INSTITUTE OF TECHNOLOGY, ROURKELA” submitted by Mr. Ranjit. Narula Institute of Technology / Civil Engineering Dept / Agarpara. 1. Draft Project Proposal on Rainwater Harvesting at. NIT Campus. By. The Civil Engineering.

Some of these ponds are centuries old and are treated with great reverence and respect.

Until in Colorado , water rights laws almost completely restricted rainwater harvesting; a property owner who captured rainwater was deemed to be stealing it from those who have rights to take water from the watershed.

Now, residential well owners that meet certain criteria may obtain a permit to install a rooftop precipitation collection system. Up to 10 large scale pilot studies may also be permitted. In colorado you cannot even drill a water well unless you have at least 35 acres. In New Mexico, rainwater catchment is mandatory for new dwellings in Santa Fe. In Australia rainwater harvesting is typically used to supplement the reticulated mains supply.

Need for Water Harvesting The scarcity of water is a well-known fact. In spite of higher average annual rainfall in India 1, mm, 46 inches as compared to the global average mm, 32 inches it does not have sufficient water.

Most of the rain falling on the surface tends to flow away rapidly, leaving very little for the recharge of groundwater. As a result, most parts of India experience lack of water even for domestic uses. Surface water sources fail to meet the rising demands of water supply in urban areas, groundwater reserves are being tapped and over-exploited resulting into decline in groundwater levels and deterioration of groundwater quality. This precarious situation needs to be rectified by immediately recharging the depleted aquifers.

Hence, the need for implementation of measures to ensure that rain falling over a region is tapped as fully as possible through water harvesting, either by recharging it into the groundwater aquifers or storing it for direct use.

Science of Water Harvesting In scientific terms, water harvesting refers to collection and storage of rainwater and also other activities aimed at harvesting surface and groundwater, prevention of losses through evaporation and seepage and all other hydrological studies and engineering inventions, aimed at conservation and efficient utilization of the limited water endowment of physiographic unit such as a watershed.

Rain is a primary source of water for all of us.


There are two main techniques of rainwater harvesting: Storage of rainwater on surface for future use. All the secondary sources of water like rivers, lakes and groundwater are entirely dependent on rain as a primary source.

The term water harvesting is understood to encompass a wide range of concerns, including rainwater collection with both rooftop and surface runoff catchment, rainwater storage in small tanks and large-scale artificial reservoirs, groundwater recharge, and also protection of water sources against pollution. The objective of water harvesting in India differs between urban and rural areas.


In urban areas, emphasis is put on increasing groundwater recharge and managing storm water. The system mainly constitutes of following sub components: Documents Similar To rain-water-harvesting-Seminar-Report-pdf.

Trinh Huu Tung. Bekir Karaca. Yogendra Rana. Methods of harvesting water: Tanks and reservoirs are used to store the water.

By building pits, dug wells and by recharging ground water. Rainwater can be harvested from the following surfaces: Surface runoff Harvesting: In towns and cities, rainwater flows as surface runoff and this could be stored for the future use by implementing correct methods.

Rooftop Rainwater Harvesting: In this method, the rainwater is directly stored, at where it falls. The components needed in this type of harvesting are: Catchment First flush Filter Catchment: The surface which takes the rainwater is called catchment and the catchment may be a terrace, open ground area etc.

Transportation: The water from the catchment is taken down through the pipes to the harvesting place. First flush: the First flush is a machine provided at the outlet of transportation pipes and used to flush the water to avoid any contamination.Components of Rainwater Harvesting system 5.

Provides self-sufficiency to your water supply and to supplement domestic water requirement during summer and drought conditions. There are two main techniques of rainwater harvesting: Storage of rainwater on surface for future use. Recharge wells: Hydro Geological Surveys in the locale were completed by Central Ground Water Board, amid , and and point by point hydro geographical and water adjust ponders were completed under Ghaggar and Upper Yamuna Projects.

Silt deposited on the filter media should be cleaned regularly by removing the top deposited silt. Now, residential well owners that meet certain criteria may obtain a permit to install a rooftop precipitation collection system. Annual Rainwater Harvesting Potential: Storage tanks should be covered to prevent mosquito breeding and to reduce evaporation losses, contamination and algal growth.
