the Brl 110 million Jardim damasceno pump Station in the far north region
of Sao paulo, Brazil, was designed to solely and exclusively supply water to
the 330,000 inhabitants of the Jaragua sector. the pump station will also help
to normalize chronic water distribution problems in the sector where poor
communities receive intermittent service due to water shortages in the Jaragua
reservoir for up to 12 hours per day.
Sabesp used Watercad to perform hydraulic modeling of multiple supply
scenarios to find a solution. the pumping station was designed with four
motor-pump sets of 2,500 horsepower each, divided into two phases of
implementation. the goal of full supply in the region was achieved and 550
liters per second were added to the average flow at an increased profit.
Water Supply in Risk Area
Sao Paulo, Brazil
When the Jardim da conquista pump station shuts down due to power failures,
approximately 240,000 people in Sao paulo, Brazil, remain without water
overnight until Sabesp restarts the pumps the next day. to solve this problem,
Sabesp performed modeling with Watercad that simulated the hydraulic
conditions. By understanding the operation of the entire system, the company
was able to define a cost-effective solution.
construction of a new reservoir with an oversized volume provided sufficient
autonomy to ensure water supply until the morning after a power outage.
Watercad determined existing operating conditions, tested new pump setups,
and determined how long the pumps would take to fill the new reservoir. the
total project cost was Brl 20,000, and with resulting savings of Brl 1. 1 million,
the return on investment was 55 times the project cost.
