Sustainability Projects
There are several exciting projects getting started in 2010 at the wastewater treatment plant.
- The largest project has the City working with an engineering consultant to evaluate design options for the wastewater treatment plant Headworks Building. The Headworks Building is the first step of the wastewater treatment process. As raw wastewater enters the plant influent, large debris is removed by screens and smaller debris is removed by aerated grit basins. This debris is removed to prevent damage to downstream equipment. The debris is processed by grinders and washers before it is discharged to a conveyor that deposits the dry material in a dumpster. The existing Headworks building was constructed in 1976 and much of the equipment, HVAC and electrical systems have reached their design life expectancy. The engineering consultant will be evaluating whether it is more economically feasible to construct a new Headworks building or to retrofit and rehabilitate the existing building.
- The four primary clarifiers are also being evaluated by the engineering consultant to determine the extent of structural and mechanical repairs needed. The primary clarifiers remove a large portion of the settleable solids in the wastewater. Most of the equipment and concrete structures exist in a very corrosive environment which causes structural and mechanical deterioration requiring frequent rehabilitation.
- Other smaller improvements that will increase the efficiency of the plant operations are being evaluated by the engineering consultant. The design phase of these projects is scheduled to be completed during the first half of 2011 and construction immediately following.
