Description

Unfunded Amt

$2,978,000

69 Aeration Eqiuipment

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. Replace RDT 1 and 2 with in-kind process equipment or a more efficient process equipment. This will include all ancillary equipment required to make this an operational and a direct replacement for the existing RDTs 1 and 2 and all of their ancillary equipment. The project includes the replacement of the control panel and aquisistion of a redundent pump. 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 buildng heat and electical supply. 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. Construction of a two million gallon ground or elevated storage reservoir with associated pumping station and generator west of US-218. Current land acquired for this reservoir is southeast of the Slothower Rd at Hebl Ave This project will be for the reduction of dissolved nutrients (i.e. nitrates) in the source water. The project is preceded by a study. The study will review treatment technology options (i.e. reverse osmosis, biological treatment) and the long-term viability of continued lime softening. Add underdrains, granular media, controls, and instrumentation to filter bay #6. This bay was left unfinished to allow for future expanded production. The project will also repair or replace a number of filter control valves. The project will be informed by the Treatment Study. Replace aging medium voltage (13,200V) cabling and install communication fiber to wells at the Water Plant and Peninsula sites.
