    1> Recharge Tubewell Technique
    The purpose of recharge tubewell to directly feed depleted aquifers with fresh rain water from surface so that the recharge takes place fast and there is no transit or operational losses.

    What is the "Need"?
    • To improve that quality of ground water.
    • To augment the ground water storage and decline of water level.
    • To meet the ever increasing demand for the water.
    • To reduce ground water pollution.
    • To reduce the cost for pumping of ground water as it raises ground water table.
    • To reduce the soil erosion in urban areas.
    • To reduce salinity ingress in ground water.
    • To reduce evaporation losses as water storage in under ground.
    • To recharge rainwater in zones directly & immediately in which we draw ground water for Agriculture, Drinking & Industries.
    • To reduce flood peaks & to store surplus rain water for future uses.
    • To supplement domestic water requirement during summer, drought etc.
    • To reduce the runoff which chokes storm drains.
    • The new latest system is totally transparent.

  • Geohydrological Investigation for Rainwater Harvesting System

    • A. Collection of Hydro geological data
    • B. Geological & Hydro geological Maps, Soil Maps, Water Quality data
    • C. Drilling of bore holes
    • D. Water Table Zones
    • E. Porosity & Hydraulic conductivity
    • F. Hydraulic Gradient
    • G. Calculating Ground water flow & Direction, cone of Depression
    Why Pump Test?

    • 1. To find out the Hydraulic Properties of an Aquifer
      i.e. Aquifer Test
      a) Transmissivity (T)
      b) Storage co-efficient (S)
      c) Hydraulic conductivity (K)
      d) Well Performance
      e) Safe yield

    • 2. Pumping test which provides information about the yield and draw down of a well
      i.e. Well Test & Efficiency of well
      To evaluate the following parameters
      a) Formation loss (BQ)
      b) Formation loss co-efficient (B)
      c) Well loss (CQ2)
      d) Well loss co-efficient (C)
      e) Efficiency of the tubewell
      f) Specific capacity Vs Discharge relationship
      g) T & S Value

    • For above instigation data one discharging well (Size 250mm dia. X 200 mts depth) and one piezometer tubewell (Size 150mm dia. X 200 mts depth) required.
