( ' Carol on ,�"Ci ty Secretary Posted this the i,r,/, day of L ,/,-y/2 .--V , 19W , at M. Staff Report to Mayor and CityCouncil DATE: SUBJECT: NO: 8-5-88 SEWER TAP FOR ONE LOT IN LAKE RANCH ESTATES A Home Builder has approached the City of Wylie with a request to connect a new home he is currently planning to build in Lake Ranch Estates to the existing sanitary sewer line in Washington Place within Presidential Estates Subdivision. As you are aware the Texas Water Commission (TWC ) has issued an Enforcement Order against the City of Wylie which requires the elimination of the "Pump and Haul " method of wastewater transportation. This connection to the existing sewer with a new sewer service would increase the amount of wastewater which the City would have to transport . I feel that the addition of this one household to the Presidential Estates sewer system would not have a significant impact on our operations , nor would it be any different from adding a new household within Presidential Estates . I do not feel that the TWC will have a negative response to including this household because it will help put an end to the numerous septic system pollution loads on the area drinking water supplies. Therefore, I recommend that the sewer service be approved. ORIGINATING DEPT.HEAD DISPOSITION BY COUNCIL Ron Homeyer, Assist. City Engineer FOR ADD.INFO. CONTACT: OTHER: Ron Homeyer, Assit.
