Work to be performed under this Construction Services project requirement includes:

· Replace an extended aeration WWTP and associated infrastructure, that is more than 50 years old. The infrastructure includes two disposal ponds, a force main that connects the WWTP to the disposal ponds, and effluent spray field, and a recreational vehicle dump station;

· The existing plant will be demolished, one pond will be replaced with an enclosed holding tank, the other pond will be demolished, the force main will be replaced, and a recreational vehicle dump station replaced; and

· The existing treated effluent disposal spray field equipment will be replaced with new lower maintenance spray equipment.
