The intent of this ongoing Program is to review and manage the capacity of Phoenix's wastewater collection system to avoid sanitary sewer overflows. Managing capacity is a basic tenet of the City's Capacity Management, Operations, and Maintenance Program. The primary trigger for identifying capacity concerns is when the City's sanitary sewer model indicates that sewer segments are flowing at or above 80 percent of the maximum capacity during peak dry weather conditions. Sewers in this Program are "bottle necks" in the Wastewater Collection System and are the first to show up with capacity problems. Increased capacity is provided by installing new parallel sewers or larger replacement sewers. In some cases, diversions can be constructed to re-route wastewater flows into other sewers that have more excess capacity. If flows increase in the future, segments upstream and downstream may reach the 80 percent trigger point and need to be added into the Program. Work includes replacing approximately 4,500 linear feet of existing 8-inch sanitary sewer with new 12- inch and approximately 1,200 linear feet of existing 12-inch sanitary sewer with new 15-inch, in the area of 27th Avenue and Camelback Road. The method of Contractor Selection has not been Determined at this time.
