It has been another momentous year for Cary's wastewater utility. Within the last year, our three wastewater treatment facilities have been optimizing their operations. As charter members of the American Water Works Association's Partnership for Clean Water we are dedicated to fulfilling the organization's focus on self-assessment, optimization and continuous improvement of our wastewater collection and treatment operations. This program for wastewater utilities is very similar to the Partnership for Safe Water program in which Cary has participated for 15 years with our drinking water utility. This June, two of our wastewater facilities received Director's Awards for completing their optimization plans. Our wastewater system, or what is often called the sewer system, is an extensive network of approximately 990 miles of pipelines and 40 wastewater pumping stations that has captured and conveyed more than seven billion gallons of wastewater without losing more than a tiny fraction of a percentage to overflows or spills. Our three wastewater treatment facilities have also performed exceptionally well in removing organic materials and nutrients without incurring any federal or state violations. We are very proud to report that highly treated water returned to creeks and streams from our treatment facilities is noticeably cleaner than the water in the streams. The nutrients recovered from wastewater treatment are heat dried and made into Class A, Exceptional Quality biosolids pellets. Our high quality biosolids are beneficially reused for soil conditioning and nutrients to improve soils in agribusiness applications. We also recover a portion of the treated water from our facilities to provide high quality reclaimed water for irrigation, cooling towers and numerous reuse applications. Our report highlights the ongoing efforts underway to preserve and protect the Town's infrastructure investment through rehabilitation and replacement of critical pipelines and infrastructure systems. Protecting Cary's infrastructure is essential to the wastewater utility operations as we work to shape the future as outlined in Cary's Community Plan. We invite you to study this report and experience how well Cary's wastewater systems are meeting current and future needs to protect the environment with sustainable wastewater services. Jamie Revels, P.E. Director of Utilities
