RAIN WATER HARVESTING

Rain Water Harvesting (RWH) & Ground Water Recharge (GWR)

Approach: – Our all designs track latest Standards / guide lines and Techniques for development of efficient RWH & GWR systems.

  • Roof top Rain water Harvesting

Basic Requirements:-

  • Type of roof.
  • Roof top area.( Catchment )
  • Slope of roof.
  • Drainpipe arrangement & Lay out.
  • Present outlet position.
  •  Space for Filter & Sump.
  • Storage/ Collection Tank or Bore well for recharge.
  •  Annual rainfall & monsoon rainfall data with Intensity & duration with average rainy days in a month & Peak rainfall data.
  •  Assessment of total demand of water and what percentage of available rain water needs to be stored or diverted for recharge.

RWH System is designed adopting following methodology:-

  • From monsoon/ annual rainfall data, area & type of   catchment, the quantum of available water is estimated. Technical Design of pipe line, filter is done to accommodate peak rainfall flows.
  • Design of gutter size/ length / pipe size and rain water carrying channels up to storage/recharge facility are designed.

 

  • Storage or recharge facility is designed as per availability or as per Demand.
  • Instead of conventional filter pit system adoption of latest filter paraphernalia are adopted.
  •  First Flush system is provided.
  • If storage is required measures for dis-infection are proposed. Incase of GWR adequate measures were suggested to keep inflow rain water free of pollution & impurities.
  • Only conceptual drawings (Line diagram) of works required along with tentative cost estimate and specifications along with anticipated benefits and economic analysis is supplied.

  • OUR EXPERTISE ALSO WORK ON DEDUCTING LEAKAGES / WASTAGE IN YOUR PLANT PREMISES AND SUGGESTS FOR THEIR REDUCTION AND IMPROVEMENT TO EXISTING WATER DELIVERY INFRASTRUCTURE TO ACHIEVE EFFICIENT AND ECONOMICAL WATER USE.

 

B. Ground Water Recharge:-
Basic Requirements:-

  • Type and total area of catchment (field or Factory yard etc.)
  • Drawing/ Map of total land area (Catchment) preferably with 0.5 m counter interval indicating arrangement of buildings, roads, boundaries & other utilities. Slope of land area & direction of sloping in case counters are not provided to assess direction of natural flow of rain water over the land .Details of existing Drainage arrangement & its  Lay out and final  outfall  position.
  • position of existing tube well/bore well and open wells with size, depth & present yield ( Outflow discharge) with normal running in hours and drawdown in meters ( lowering of water table) and time and height of recoupment.
  •  Space for Filter & Sump and location of Recharge Bore wells and Recharge shafts.
  • Annual & monsoon rainfall with intensity, duration and average rainy days in a month and peak rain fall data.
  • What percentage of available runoff needs to be recharged?.
  • Type of geological formation in area and permeability /infiltration rate etc.  

GWR system is designed mainly adopting following methodology:

      • Total annual & monsoon rainfall & rainfall intensity & duration data are collected.
      • Based on local geological formation and rate of recoupment an provisional assessment of   permeability and infiltration rate / (Recharge rate) is done to design filter system and to estimate number and type of recharge structures required for recharge.
      • Design of water carrying channel (Drainage system).
      •  Technical Design work of filter system, recharge shafts/ recharge trenches, injection well etc depending up on site specific requirement.
      • Design of recharge system for existing bore or open wells.
      • Assessment of total recharge volume and benefits of recharge with economic analysis.
      • Only conceptual drawings (Line diagram) of works required along with tentative cost estimate and specifications are supplied.
