Wastewater Engineering:
Sewer Lift Stations
|
|
|

|
WEI has designed many sewer lift stations, including submersible, surface and recessed wet well mounted lift stations, and flooded suction wet well and dry well stations. Designs include variable frequency drives and harmonic distortion suppressors, sewage aeration, well and chamber ventilation, and web-based SCADA ethernet radio and telemetry monitoring, SCADA, and warning systems, and manual and automatic power transfer backup systems. WEI is very experienced in force main design, evaluating flow velocities over a full range of operation to balance self-cleaning velocities with pressure head. WEI provides innovative cleanouts on force mains for easier maintenance. WEI has prepared most of the State required site applications associated with the lift stations and force mains. Gerald Williams, owner of WEI, has developed a software application to assist in the design of lift stations, providing 19 pages of analytical results.

15-1/2 Rd. & I-70 LS's, Fruita, CO
Preliminary evaluation and design of 5 lift
stations and final design and state health
dept. approval of 2 lift stations, one a 583
gpm recessed wet well mounted station, the
other a 994 gpm dry pit with wet well.
Both stations have variable frequency
drives and web-based SCADA ethernet
radio monitoring system and back-up
power systems. A special design
consideration was the potential future
reverse flow direction to a new WWTF.
The 994 gpm station could pump the
opposite direction in the force main
designed for the 583 gpm station. Both the
station and force main were designed for
the two flow direction conditions.
Limekiln Gulch Lift Station, Grand
Junction, CO
Abandonment of one lift station and the
design of a new 388 gpm surface wet well
mounted lift station.
Hwy 6 & 50 RV Park Lift Station,
Grand Junction, CO
Designed a small package lift station for
approximately 50 residences.

Redlands Village North Lift Station,
Grand Junction, CO
Abandonment of one lift station and design
of a larger 273 gpm surface wet well
mounted lift station.
Country Club Park Lift Stations, Grand
Junction, CO
Designed 11 individual lot effluent pump
stations to provide centralized sewer to
property owners of 2 subdivisions.
Connected Lakes Lift Station, Grand
Junction, CO
Abandonment design of two lift stations
and design of a larger 288 gpm recessed
wet well mounted station lift station.
Rosevale Lift Station, Grand Jct. CO
Designed a 313 gpm recessed wet well
mounted station.
North Delta Lift Station, Delta, CO
Designed a two phase lift station, with a
submersible grinder for Phase I and a 229
gpm recessed wet well mounted for Phase
II.
