Constructing a Pipeline to Partnership

The Otay Water District, located in San Diego, California, identified the need to replace 3,000 feet of deteriorating pipeline. As the Inter-Connection Project was developed, the pipeline grew from 3,000 feet to over 12 miles. The modified project allows the transfer of water between two distinct service areas. This pipeline, both eliminated and delayed construction of additional reservoirs in both service areas. Through the utilization of a pipeline, the District optimized their storage capacity of potable water, and increased service reliability to their customers. The project has provided several opportunities for partnerships through the creativity of the District. The District developed a construction philosophy of "Construction Manager/Constructor" (CM/C) for the project. The CM/C philosophy employed the construction manager as the general contractor, in a not-at-risk relationship, who in turn was responsible for securing, through public bidding, subcontractors to complete specific aspects of the work. The project was divided into 54 distinct construction contracts, creating increased opportunities for small and local contractors to participate in what has become the single largest capital improvement project undertaken by the District.
