The Kulgaon Badlapur Municipal is thankful to your team for suggesting and carrying out necessary measures for restoring our water supply which was badly affected by the 1-day cut on every Friday. Now we get water supply in time, which has avoided law and order problem in this area and saved expenditure on large number of tankers.
Thanking you and your team for this grand success.
WSSD, India47 Appreciation from Government/ Local Bodies
Due to measures as suggested, there is marked improvement in water supply of cities in MMA.
Venkat Kalyankar, Officer on Special Duty, Government of Maharashtra
WSSD, India48 Avoided law and order problem
. Millions faced water problem . water was not reaching in stipulated time . Our study- mitigated this crisis . Re-engineering of the system . Satisfaction of common people . All people get water now in time . Solved the law and order problem . Mitigated the crisis.
WSSD, India49 Time Saving
. Water-not reaching tail end of the system . It took 14 hours to fill the empty pipelines . 30 hours to fill storage tanks. . Our work- saved crucial time lag of 30 hours . Time value of this saving cannot be measured . Concerns life sustenance of millions of people..
WSSD, India50 Money Saved
. Normally, daily life sustenance of one person require 20 liters. . If we consider volume of 1 tanker as 10,000 liters, for 500 persons we require 1 tanker. . This means for 1 million people we would have required 2000 tankers . And to cater for all, we would have required total 14,000 tankers . Even assuming 25 % population get water from local sources . We would require Rs 70 million/week . Therefore, for 6 months we saved Rs 0.42 billion
WSSD, India51 Sustaining Water Infrastructure
. The quality of drinking water supplied by the tanker is not assured . Our work has improved quality of drinking water- no tankers . Supplying water in time has improved service delivery . Minimized health risks and mortality . Improved image of department and Government . Water Gems Simulation Technique- enhanced reliability and sustaining power of water infrastructure in the region
WSSD, India52 . Indigenous model prepared in-house . Full fledged GIS model first time in India . Hydraulically balanced EPS model with large number of dynamic controls (27 dynamic controls) . Length of pipe network = 734,953 m . Number of valves = 67 . Number of tanks = 66
WSSD, India53 Overcoming the hurdles MIDC ID . Complex demography 19 MMR (archipelago, rivers, dams etc) ULBs DA
. Data collection and collation Centralized MJP Integrated ZP Model . Pipe network in brain, not on
computer Diverse Data from different sources . No inter communication captured under single model amongst various water utilities . No interlinking
WSSD, India54 . Considering importance of our indigenous model, GoM decided to replicate the crisis management model for the entire state. . All satellite images and digitized maps of all 247 cities/ towns of the state are being acquired. . Full fledged GIS model shall be prepared for all these cities in the state of Maharashtra. . The hydraulic EPS model using Water Gems shall also be used for transformation of intermittent water supply to 24x7 systems besides this crisis management model. WSSD, India55 We This experimented area, when on calibrated MMA is a vast disaster hydraulic area with struck, does model built in state’s 22 % not allow us to Bentley Water population experiment on and and is a field WaterGEMS growth engine haphazardly which when for India which might implemented, cause nuisance mitigated the disaster.
Our solution using hydraulic model mitigated the disaster.
