Best Rainwater Harvesting Service and Consultants Bangalore

Rainwater harvesting is a sustainable practice that involves collecting and storing rainwater for later use. This method helps address water scarcity issues, especially in regions with irregular rainfall patterns or limited access to freshwater resources.

Hamsa Enviro Energy Solutions has been a leading Rainwater harvesting service and consultant provider across south India since 2009.

  1. Roof based Rainwater Harvest System(RWHS)

Rooftops: If buildings with impervious roofs are already in place, flat & and sloped roofs, the catchment area is effectively available free of charge and they supply the point of consumption. This water can be stored by filtering water, with adequate filtration systems, depending upon the available catchment area, such as wall mount mechanical filters,(for independent houses and small apartments) ancient sand bed filtration systems with settlement tanks for big apartments, commercial complexes, and industries. The same can recharge the Earth or Bore well.

   2. Land-based 

    A. Groundwater recharge in rural areas

  • Gully plugs

  • Contour bund

  • Gabion structure

  • Dug well recharge

  • Bore well recharge

  • Groundwater dams e Percolation tank

  • Check dams / Cement plugs / Nala bund e Recharge shaft

  • Sub-surface dykes

  • Lake

  • Pond

    B. Groundwater recharge in urban areas

  • Recharge pit

  • Recharge trench

0 Trench with recharge well 0 Stormwater recharge well

  • Footpaths

  • Landscape e Parks

  • e Roads

        Benefits of Rain water Harvesting 

  • Rainwater is relatively a clean and free source of water, at the point where it is needed

  • It promotes self-sufficiency and conserves water

  • It uses a simple technology which makes it easy to maintain

  •  Provides safe water for human consumption after proper treatment with low running costs

  • Can supplement other sources of water supply

  •  Reduces flood flows & and dependency on groundwater

  •  Improves the quality of groundwater through dilution when recharged

  •  Reduces soil erosion as the surface runoff is reduced

  •  The structures required for RWH are simple, economical, and eco-friendly.

  • RWH System can also be set with the already existing infrastructure

  •  Yields high-quality water - pure, soft, with low minerals, free of organic matter and chemicals

  • In coastal areas, where the water is saline, RWH is the panacea

  • Saving of energy to lift groundwater(One-meter rise in water level saves 0.40 kilowatt hour of electricity)

Importance of the RWH system

Water scarcity has become a major problem due to varied reasons. An ideal solution to combat water scarcity is to reuse and recycle the available water. In tune with this, it is cost-effective and environment-friendly to install the RWH unit in every household. RWH unit captures the rainwater which will otherwise flow down the drain and makes it reusable for any purpose whatsoever. The efficacy of RWH lies in making the rainwater even potable which means rainwater can be used for drinking and even to cook after scientifically treating it.

RWH is most suitable where -

  • Groundwater is scarce

  • Groundwater is contaminated

  •  The terrain is rugged or mountainous,

  • Seismic & and flooding events are common,

  • The aquifer is at the risk of saltwater intrusion,

  • Electricity & and water prices are rising

  • Water is too hard or mineral-laden

The potential of the RWH system

The total amount of water that is received in the form of rainfall over an area is called the rainwater endowment of that area. Out of this, the amount that can be effectively harvested is called the water harvesting potential. Among the several factors that influence the RWH potential of a site area, climatic conditions especially rainfall quantity, pattern (region, dry period & and storage structure), and catchment characteristics are considered to be the most important.
