General practice(s)
Random decision of depth and slotted portion
Our efficient practice(s)
Geophysical study & Groundwater Level Measurement
Drawbacks
  • No proper recharge
  • Clogging of slots likely
  • Chances of contamination
Benefits
  • Proper recharge ensured in good aquifers
  • Less chances of clogging of slots
  • Contamination can be minimized

General practice(s)
No attention paid
Our efficient practice(s)
Recharge test done in existing borewell
Drawbacks
  • Either insufficient or more than required capacity structure leads to improper recharge or overexpenses
Benefits
  • Proper estimation of design and capacity of recharge structures

General practice(s)
PVC SWR Non-ISI pipes are used as casing
Our efficient practice(s)
PVC Pressure pipes conforming to ISI and atleast 6kgf/cm2 rating are used as casing
Drawbacks
  • Surrounding pressure of gravels may result in pipe collapse leading to failure of recharge borewell
Benefits
  • Strong casing prevents pipe collapse, thus providing success and long life to recharge borewell

General practice(s)
Casing pipes have round holes or are manually- slotted parallel to length, with no particular attention to slot width, length, arrangement and distance between slots
Our efficient practice(s)
Casing pipes are company slotted and transverse to length with adherence to parameters as per IS:12818-2010 and IS:4985-2000
Drawbacks
  • Less recharge rate due to less available open area
  • Hindrance to water flow as water has to change direction to enter vertical slots
  • Round holes are not only unable to prevent finer impurities from entering the borewell but also highly susceptible to clogging
Benefits
  • High recharge rate due to more slots per unit surface area
  • Free flow of water as it doesnot have to change direction to enter transverse slots

General practice(s)
Ordinary crusher gravel with pointed ends or ungraded & unwashed river gravel with organic impurities is used as gravel pack in recharge bore well
Our efficient practice(s)
Rounded or sub-rounded, graded and washed silica gravel of standard size (3-6mm) is used as gravel pack in recharge bore well
Drawbacks
  • Clogs easily
  • Proper development not possible
  • Percolation rate not sufficient
Benefits
  • Less chances of clogging
  • Better development of borewell
  • Better percolation rate

General practice(s)
Due emphasis not given on development of recharge bore well before final commissioning of rainwater harvesting system
Our efficient practice(s)
Development of recharge bore well by bailing machine is done before final commissioning of rainwater harvesting system
Drawbacks
  • Mud and other foreign matter remains lying inside the recharge borewell as well as clogging pipe slots, thus reducing recharge rate
Benefits
  • Ensures removal of silt and any foreign matter which might have entered recharge bore well during drilling, thus improving recharge rate

General practice(s)
Portion of casing pipe in recharge pit is manually- slotted parallel to length to allow entry of rainwater into recharge bore well
Our efficient practice(s)
V-Wire Screen is fitted with portion of casing pipe in recharge pit to allow entry of rainwater into recharge bore well
Drawbacks
  • Scattered, less no. of slots lead to slow recharge process
  • Highly susceptible to clogging leading to hindrance during recharge process
  • Hindrance to water flow as water has to change direction to enter vertical slots
Benefits
  • Continuous slots in V-Wire screen increase open area significantly so as to accelerate recharge process significantly
  • Very less chances of clogging due to inwardly widening V-shaped slots leading to sustained recharge process.
  • Superior flow properties due to transversely arranged slots in V-Wire screen boost recharge process along with low turbulence

General practice(s)
Not enough attention is paid on providing ventilation in rainwater harvesting structures
Our efficient practice(s)
Proper ventilation of filter pit, recharge pit and recharge bore well is done by making provision for air pipes
Drawbacks
  • Air displaced by water is trapped in the system and with no place to escape, tends to hinder proper movement of water
Benefits
  • Air is not trapped in the system,thus proper flow of water is maintained during entire process
