East rocky view regional Wastewater System
East Rocky, Canada
this project provided a centralized wastewater collection and treatment
system for the hamlets and towns in the east side of East Rocky, Canada,
affecting about 90,000 inhabitants. A challenge was to model 18 lateral lift
stations tying into a regional force main. Using WaterCAD, every tie point of
the lift station was assigned a node and the nodes were isolated from the
regional force main with residual pressure at the tie point.
Once the horsepower of the pumps and the size of the lateral force main for
every lateral lift station were determined, the disconnected nodes at the
tie points were connected to the force main to confirm whether the residual
pressure at the nodes before connecting is similar to the residual pressure
after connecting the nodes.

Hydraulic Model of Water Network
Chełm City, Poland
the goal of this project was a full diagnostic of the water network system,
analysis of water demand for Chełm City in Poland, optimization of water
networks, and connection to a SCADA system. The challenge was the scale of
the project, short time for implementation, lack of data, and mixed formats due
to data acquisition from many sources.
The project involved 300 kilometers of water systems and 15,000 pipes. With
WaterCAD, MPGK built one of the first complete hydraulic models of the water
network in Poland. WaterCAD helped MPGK save money, analyze the demand
for water, save water, and preserve the environment, helping to sustain society
as a whole.
