Condition Report: The water treatment plant structures are in good overall condition. General maintenance of all buildings and structures is required on a regular basis.
Completed Improvements: The original structures of the water treatment facility were constructed in 1916. The facility was expanded with additional filters in 1954. Maintenance and improvements are planned and completed on the facility on an on-going basis. However, the following major improvements were completed in recent years:
- Added the carbon building and feed system.
- Replaced chemical feeders.
- Added pumps station and main to transport lime residual to the WWTP lagoon.
- Replaced low service intake pumps with more energy efficient pumps.
- Replaced chemical feed pumps with energy efficient peristaltic pumps.
- Replaced high service pumps with more energy efficient pumps.
- Added sodium hypochlorite feed system and storage to replace the use of chlorine gas.
Energy Conservation Efforts
- Change pumps and motors to more efficient ones when replacement is needed.
- Occupancy sensors (motion detection) lights in shop and warehouse.
- Boiler replaced with more energy efficient one for heating of main building (2004)
- Brick rehab on main building (2008-2009)
- Replacement of windows to double insulated glass
- Occupancy sensors (motion detectors) throughout the rest of the plant and buildings
- Replacement of shop roof and ammonia building roof
Needed Energy Efficiency Projects
- Construct 3-5 megawatt electrical generation facility at Hamm’s Landfill.
