24x7 Water Supply & Distribution Jain Irrigation’s Experience
Venue: India Water WeekDate: 9th April 2013
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 24x7 is Sustainable & Successful ? No Leakages in the network No Contamination of water Assured Water supply to all levels of society Negligible Wastage of water by public Unauthorized connections can be restricted Consumption is reduced - effective use of water Pay As You Go charging basis Regular Revenue Generation ULTIMATELY - Customer is HAPPY
Experience of Jain Irrigation in 24x7• Supplied, Installed, Commissioned 24x7 Water Supply & Distribution Systems in the state of Karnataka (Year 2008) Four major cities in Karnataka: Hubli, Dharwad, Belgaum & Gulbarga
24 x 7 System is working satisfactorily since 4 years

Water Tariff for Volumetric based BillingWater consumption up to 8,000 liters = Rs 48 per monthWater consumption up to 15,000 liters = Rs 120 per monthWater consumption up to 25,000 liters = Rs 250 per monthWater consumption beyond 25,000 liters = Rs 300 per month
for Gulbarga City (Karnataka)
Results of 24x7 Water SupplyWater consumption is reduced by 40% to 50% (with assured water supply, LPCD demand is reduced in 8 months)
Operation and Maintenance Cost is reduced by 30% to 40%
Revenue of Corporation increased by 4 to 6 times
Loss of Water reduces from 50% to 11%Belgaum: 11%, Gulbarga: 3%
Safe, Corrosion & Contamination free Continuous Water Supply is assured to Customer

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)
