Description

Unfunded Amt

67 Geo-Thermal Hvac Conversion Project would include the conversion of the HVAC system to Geo-Thermal. Installation of Geo-thermal loops, new pump systems, new chiller, and improved controllers required to operate the system.

$300,000

68 Secondary Calrifier 5300-5400 Repairs

This project will replace the rake mechanisms and drives for Calrifiers C5300 and 5400 that were new in 2002 and part of WWTP upgrades. Project would require the addition of natural gas fired area heaters. Initially the heat load would be enough to keep the building above freezing. When the digester rehabilitation project proceeds, glycol heating from the digester boilers would be included that project. Glycol piping would be routed under the parking lot and drive to the building to new heating units. Replace the remaining mixers in the aeration trains 1 - 4 with high efficiency mixers matching those placed in Cell 9 of trains 1-4 and replace mixers in the high strength tank. This would be total of 30 mixers. Replace Lamson 300 HP Centrifugal Blower with a High Speed Turbo Blower including any ancillary equipment, pipe modifications and PLC programing. We currently utilize service contract for yearly maintenance for two existing high speed blowers installed. We would want to require service contract for hte new high speed blowers once the warrenty period had expired. Rehabilitation includes demolishing the existing building, converting the station to a wet-well valve vault with surface hatches for pump access, basket screening, new standby generator, replace 20 year old pump, new controls, valve vault with bypass capacity, new security fence, landscaping and access road improvements. The station would be plumbed for future expansion, but would not include additional pumps. The project includes the replacement of the control panel and aquisistion of a redundent pump. Install a fourth Effluent Water Pump to serve the in plant distribution system and soccer park irrigation system. Work includes rebuilding of the Amiad filtration system. Build a 40' x 60' structure over Ultra Violet disifection structure for protection and for storage of the UV bank modules during the off season. Project will include buillding heat and electrical supply. Funds requested below are for design with construction to follow in 2029.
