INNOVATION IN WATER RESOURCES
National Water and Sewerage Corporation
gulu intervention Program
the goal of this project was to improve the water supply and sewerage services
in the Gulu municipality of Africa. Challenges included security issues, lack
of data, limited funds, lack of experience, few references, procurement and
financial regulations, and Uganda Electricity Board regulations.
Using WaterCAD, the National Water and Sewerage Corporation was able to
complete its project, providing a reliable water supply, improved sanitation,
increased service coverage and sales, and reduced nonrevenue water loss.
It expects a full return on investment within three years. Already, WaterCAD
has saved the corporation a year’s time and $50,000.

Use of Hydraulic Model for the Optimization and Losses Reduction Planning – The Passagem Funda Water
São Paulo, Brazil
the Passagem Funda Water System is located in Brazil, where it uses 274
kilometers of pipe to serve 240,000 inhabitants. It suffered from topographic
differences of up to 100 meters and a total loss of about 880 liters per service
connection daily. Hydraulic simulation by the team of engineers of Sabesp was
important both for diagnosing and redesigning the system.
WaterCAD enabled Sabesp to diagnose the system of distributing water and
helped to determine actions to reduce losses of water in areas that had the
greatest indicators. From the model, it was possible to identify the critical
areas of water losses and propose solutions to eliminate leakage. The project
succeeded in reducing water loss by 57 percent, saving $170,000 per month to
produce potable water.
