The population of New Cairo, Egypt, is expected to grow from about 350,000
people to 5 million by 2020. With a budget of $3 million, the Egyptian
government is using public-private partnerships to improve and expand water
service to New Cairo. To this end, CH2M HILL was contracted to evaluate the
hydraulics of the New Cairo Raw Water System.
CH2M HILL built a hydraulic model of the system. WaterGEMS performed
extended-period modeling simulations for pump cycling evaluation, and
HAMMER performed hydraulic transient (surge) analyses to size surge tanks for
the system. Information from the analyses will allow appropriate modifications
to the surge protection system and operating procedures, and ensure a
sustainable water system.
Analyzing Complex Stormwater Systems With Holding Ponds Below High-Tide Levels
Navi Mumbai, India
Dronagiri is a growing metropolis and one of 14 nodal townships of Navi
Mumbai in India. Three creeks and the Arabian Sea surround it, and 99 percent
of proposed land development is below sea level. CIDCO was charged with
designing the critically important infrastructure to manage stormwater runoff.
CivilStorm was used to model the stormwater system, including rainfall, runoff,
inlet capture and bypass, gravity and pressure piping, detention ponds, outlet
structures, open channels, and culverts. CIDCO constructed holding ponds for
water accumulation during high tides and heavy downpours, and for the release
of water from these ponds back into the sea during low tides.
