Upper Moreland-Hatboro Joint Sewer
Authority (UMHJSA), Willow Grove, PA
Effluent Pump Station/Ultra-violet Light
Disinfection System (2003-2007)
Permitting, design and engineering support during construction was provided
for the Authority. The project construction cost was $5.9 million and consisted of the
following:
- Effluent pump station and control system, consisting of four (4) submersible propeller pumps capable of pumping 43 MGD with 1 pump out of service;
- Replacement of the existing low pressure UV disinfection system with a new medium pressure system and controls capable of disinfecting 30 MGD;
- Construction of a new UV and effluent pump station control building.
A pre-engineered metal building was designed and constructed to house a new
Trojan 4000 Plus UV disinfection system. The building also contains the necessary
electrical components and controls for the new effluent pump station.
The effluent pump station was designed and constructed to fit inside the
existing disinfection tank. The station consists of four (4) 60 H.P. Flgyt submersible
propeller pumps, on variable frequency drives. The new pump station and associated slide
gates in the disinfection tank, gives the plant the ability to better handle peak flows during
storm conditions.
