New Jersey American water
representative source water Monitoring plan
Camden County, New Jersey, united States
new Jersey American Water prepared a representative regional stormwater
management plan for the Delaware river Basin to reduce the cost of complying
with the U.S. epA Ground Water rule. new Jersey American Water expended
approximately $33,600 per year to monitor 40 wells for eight events. The
$28,000 cost of the plan will be repaid in less than one year.
new Jersey American Water used WatercAD to develop a hydraulic model
that aided in reducing the number of triggered well samples, estimating the
composition of any water sample throughout the distribution system, and
determining total contact time for distribution system disinfection. once the
new Jersey epA approved the plan, the firm prepared plans for three other water
systems. The plans were projected to save $1 million over a 10-year period.

JIcA-Assisted Agra water supply project
The $250 million Agra Water Supply project will supply potable water to
the city of Agra, India, from the upper canal of the river Ganga. With a
maximum capacity of 375 million liters per day, the water supply will cater to a
population of 1. 5 million. one component of the project was distribution system
rehabilitation, which involved development of GIS-based asset management
and a hydraulic model for Agra.
Five pilot areas were selected for network design, water loss reduction, and
distribution management. The network model was developed with WaterGemS
for use in four activities: GIS-based spatial database creation, water network
modeling, GIS encoding and network programming, and web-based application
development. WaterGemS assisted in planning rehabilitation activities and
achieving equitable water distribution in pilot areas.
