The District’s capital improvement program (CIP) has been designed to correct structural and hydraulic deficiencies in the collection system. The sewer system was evaluated using criteria based on operation costs, frequency of maintenance, structural conditions, risk of failure and hydraulic adequacy. Pipelines within the system are compared and those exhibiting a higher risk of failure based on the evaluation criteria are given a higher priority for repair.
The District’s CIP is also used as a predictive tool to determine which pipelines in the system may be approaching their useful lives. Pipelines with a higher priority rating are placed on an increased maintenance schedule and are monitored more closely by the District.
The CIP condition assessment program identified 35 projects throughout the system. Most of the identified projects are required to correct structural problems and a few deal with hydraulic deficiencies.
The District owns and maintains equipment valued over $425 million dollars. Given the magnitude of this investment the District uses a comprehensive asset management program to ensure the equipment is maintained in a way to minimize overall lifecycle costs. The scheduled plan to repair and replace this equipment forms the basis of a long range capital improvement program or “infrastructure master plan”. Over the next 50 years the District plans to invest an average of approximately $2.5 million dollars per year in the repair and replacement of its current infrastructure and an additional $1 million dollars per year average on the installation of new equipment to meet the future needs of the community.
