Justification for approval of the PCM Is presented in the following paragraph. The Village Creek Reclaimed Water Eastern Delivery System Pump Station No. 1 is located at the Village Creek Chlorine Contact Basin 2 effluent. Chlorine disinfected water from the CCB supplies the reclaimed water pump station. Chlorine Contact Basin 2 has two parallel plug-flow chlorination basins, each with gates at the influent and effluent ends of the basin. Either or both sides of the CCB may be in service as required to treat the plant flow. To properly operate the CCB and to provide chlorinated water to the Reclaimed Water Eastern Delivery System, the gates within the CCB must be functional. The effluent sluice gate on the eastern half of Chlorine Contact Basin 2 was damaged during a storm event on September 8, 2010 and cannot be operated. The required repair will involve replacing the stem, stem guides, electric operator and associated items. We have reviewed the proposed costs and are of the opinion the costs are reasonable and fair . Please feel free to contact me should you have any questions. Sincerely yours, CP&Y, Inc. Michael F.

P275-70530023183 PCM-004 Wet Well Modifications CP&Y Project No. CFW08085 Dear Ms. Goderya: CP&Y recommends approval~ Justification for approval of the PCM Is presented in the following paragraph. -~ Future upgrades at Village Creek Wastewater Treatment Plant will involve adding UV disinfection of filtered effluent to better ensure a high reuse water quality. Water that is reclaimed and provided to reuse customers connected to the VIiiage Creek Eastern Delivery System will lnitlally be disinfected in the existing chlorine contact basin, but this will change when the future UV disinfection system ls installed. A change order is necessary to modify the Reclaimed Water Wet Well to provide isolation of reclaimed water from flow in the Chlorine Contact Basin and to provide adequate wet well volume. The current wet well is located near the effluent of the CCB in a single pump bay originally designed for an expansion CCB high-flow effluent pump. However, the pump was never installed and this bay was converted for installation of the three reclaimed water pumps that will feed the Eastern Delivery System. The size of the reclaimed water wet well will be increased by connecting a second bay which contains a CCB high-flow effluent pump. The pump in this second bay has been out of service for several years and Is not needed. The pump and motor shall be removed and this bay shall provide additional volume to the reclaimed water wet well. The walls of the two existing bays will be modified to create the reclaimed water wet well. Portions of the walls that form the outer perimeter of the wet well will be raised 11 feet to a he ight of 472.7 ft, which is equal to the height of the walkway platform above the CCB. The outer walls of the wet well will also be strengthened with concrete columns and beams to withstand the potential water depth differential between the wet well and the CCB. A 6 ft x 7 ft slide gate will be added on the opening between the CCB and the Reclaimed Water Wet Well. Initially the wet well wiU receive flow from the CCB through the slide gate which will be open for normal operation. In the future, the proposed influent pipe to the wet well will be connected to the UV system .--....ai~M-slfffe1~!"111,tf. I be closed for normal operation.
