IV. THE PHASE II SEWERAGE PROGRAM <br />A. Existing Sewerage Facilities <br />Sewerage facilities in the UDU area consist of a small collection <br />• system, a 200 gallon per minute lift station and a deteriorated treat- <br />ment plant of indeterminate capacity. Location of the facility is <br />shown on Exhibit 2 and is assessed in detail in.the December 1974 <br />report. <br />The Phase II program provides for County purchase of the existing <br />system (see Section III.A.). <br />A total of 183 living units are presently connected to the sewage <br />collection system. In 1974, an average flow of 23,400 gallons per <br />day was measured at the treatment plant, or an average flow of 128 <br />gallons per day per connection. This flow rate is considerably less <br />than the average daily water consumption and below the rates normally <br />acceptable to the regulatory agencies. Asta consequence, we have <br />estimated the average flow rate to be 250 gallons per day per living <br />unit, giving a present flow of 45,800 gallons per day. The Phase II <br />program does not include extensions to the collection system, but <br />reserve treatment and disposal capacity is essential to system <br />growth. A treatment and/or disposal system rated at 100,000 gallons <br />per day is recommended for the proposed improvement program. <br />The Phase II sewage system improvement program will consist of <br />construction of adequate treatment and/or disposal facilities. Two <br />alternative methods are considered: (1) construction of a new 100,000 <br />0 <br />8 <br />A©o3CU <br />311 OCT 2 0177 <br />J <br />
