The Capital Improvement Program (CIP) is OCSD’s continuous effort to keep our facilities operating at optimal levels. We plan, design, and prepare for the future by making sure that we meet our commitment of protecting public health and the environment. As our 65-year old plants age, we evaluate and determine how to prolong the life of those assets, or how best to replace them with improved technology and innovative solutions. We are working towards being fully prepared to deliver on the commitments made to the public by achieving the goals identified in our master plans. We are focusing our efforts on executing those projects and ensuring we continue to protect the environment and public health.

OCSD plans to invest over $2.7 billion in our infrastructure over the next ten years.
