This milestone goal is important for several reasons. Mostly, it insures the physical and environmental integrity of our sanitary sewer system for decades to come. Through the process of Cured In Place Pipe lining, (CIPP) and limited pipe replacement, the reliability and efficiency of the sanitary sewer system continues to measurably improve.
In the last 15 years, we have seen the average number of sewer blockages or back-ups in the City owned system drop from 10 per year to 1.5 per year currently. We have been able to greatly reduce the amount of infiltration or ground water entering in to the sewer pipes which have increased the capacity within the system as well as saving significant costs to the Denver Metro Wastewater Reclamation District for treatment.
The completion of this milestone by 2023 will allow our focus and resources to be directed to any needed improvements on larger sewer lines to insure capacity and integrity to meet the needs of all future growth within the City.
