Total Solution Provider For All Your Piping Needs Concept To Commissioning

Present Water Supply Systems in India is Un-sustainable

Intermittent, operation of valves zone-wise Irregular, no assured water supply Leakages Possibility of contamination during No Supply time Low supply pressure, requires individual pumping Free of Cost or per Yearly Fixed Cost Tendency of public to waste more water Maintenance results in stoppage of water supply for entire ward

24 x 7 Water Supply & Distribution System

Only Solution to Current Scenario !!

What is 24 x 7 ?

Continuous Water Supply with Constant Positive Pressure so that user may draw the water 24 hours a day & 7 days a week

Why only PE pipes ? PE (Poly Ethylene) Pipe available in coil form hence number of joints are reduced Joints are Monolithic (no external filler material is added at joints) Leak & Contamination-free supply Life of pipe is 100 years Corrosion free water is available Easy for taking branch connection (for taking new connections) House Service Connection is also an integral part of PE system Acidic or Alkaline soil-state environment do not affect PE pipe (pH ranging from 1 to 14)
