Numerous repairs to the OU waterline have also occurred causing further disruption to the neighborhood.
Staff coordinated with OU and we each agreed to replace our 14-inch waterlines by constructing parallel to and directly adjacent to each other.

The waterline improvements will be managed and paid by each entity under separate contract with the same contractor. Generally, 14-inch water piping is no longer available so the waterline was upsized to 16-inch PVC to increase flow capacity and improve system reliability by using a more common pipe diameter and material.
