RWH is the technique of collecting, storing and distributing rainwater for multiple uses. The collected water can be stored for direct use or diverted for borewell/groundwater recharge. In simple terms it is a way to capture the rainwater when it rains, for later use.


Water Crisis is common in Urban and Rural areas in India. This is more felt in urban areas due to population concentration. In hilly regions, even though water is available in limited quantities, crises are handled due to the drying up of the sources. Rainfall is one of the important source of fresh water is a significant throughout the Country. Rainwater Harvesting is one of the important solution to mitigate the water crisis as the copious volume of water goes waste during the rainy season.
Thus Rainwater Harvesting and Artificial Recharge of Groundwater have to be adopted to provide sustainability to the water supply.


Any Rainwater Harvesting system has three components: Catchment, Conveyance, and Storage. There are two classes of Rainwater Harvesting systems:

  • Systems which collect roof runoff for household use.
  • Systems which use in field or adjoining catchment to provide supplemental irrigation for Agriculture.

Following are the advantages of implementing Rainwater Harvesting in Industrial Premises;

Availability of WaterAssured water availability at the time and place of need.

Sustainability to existing Wells– It increase sustainability of wells and reduction in failure of wells due to decline of Groundwater levels.

Improvement of Groundwater Quality– It improves the Groundwater quality as dilution is the best solution for Groundwater pollution.

Reduction in Hazards-It will reduce hazards due to water stagnation and flood during the rainy season.

Reduction in Damage Cost-The damage to roads due to stagnation of water will reduce, thereby reduction in the cost of maintenance and better mobility of vehicles.

Cost-Effective– it is very cost-effective measure to conserve water.

Maintain Water Level– By adopting Rainwater Harvesting and Artificial Recharge.

Thus, Rainwater Harvesting and Artificial Recharge to Groundwater is the need of the hour as it is the most environment-friendly solution for augmenting water availability. Everybody can adopt these measures in their building of any kind or size.


Rainwater Harvesting and Artificial Recharge system are influenced by numerous site-specific parameters and factors to avail maximum efficiency and effectiveness. A few factors influencing the design of RWH & AR systems are as under: –

  • Physical & climatic parameters Hydro-meteorological data.
  • Hydrological parameters. 
  • Hydro-geological parameters.
  • Chemical quality of source & groundwater.

NEER offers its services in the following aspects:

  • To assess the requirement of Rainwater Harvesting and Artificial Recharge system.
  • To assess the confluence point of any other type of water with rainwater and suggest its handling.
  • Assess the lithology within the premises to develop the most effective, efficient, and economical Rainwater Harvesting and Artificial Recharge system.
  • To prepare a technical report on desired Rainwater Harvesting and Artificial Recharge system.
  • To design the Rainwater Harvesting and Artificial Recharge system.
  • To prepare the BOQ and cost estimates to develop a suitable Rainwater Harvesting system.
  • In the case of the development of the RWH & AR system in any of the premises, the development of the RWH & AR system attracts the consideration of the following factors that influence the cost and its implementation.
  • Channelization of rooftop rainwater up to recharge shaft.
  • Recharge shaft, which again depends upon the catchment area of the recharge shaft.
  • Availability of land for development of proper rainwater retention trench;
  • The injection method and depth of Injection well again depend upon the geological condition and aquifer parameters.
  • Expected Source water and Groundwater quality.
