Cabbiness Engineering provided construction plans and specifications for a 10-inch water transmission main to serve a new Oklahoma Municipal Power Authority (OMPA) electric power plant near Ponca City, Oklahoma. The water transmission main will provide domestic water and fire protection to the new facility. As well as a secondary source for the make-up water for the plant’s cooling towers.

​

The project consisted of the installation of 31,425 LF of 10- inch PVC (C900) waterline and 4,182 LF of 10-inch Restrained Joint PVC (C900) waterline. Both open cut trench and horizontal directional drilling construction methods were utilized to best fit particular sections of the project and environmental constraints. The majority of the water main’s alignment utilized the public right-of- way of Kay County and the City of Ponca City. Thus, permitting for each public entity involved required our design to be flexible and feasible. Additionally, the requirements of the Oklahoma Department of Environmental Quality (ODEQ) new water main design and construction guidelines were strictly maintained.

​

To accommodate the OMPA accelerated electric plant construction schedule, the new 10-inch water transmission main needed to be in service by January 1, 2014. Thus, with our notice to proceed for the project’s design being given on July 1, 2013 the Cabbiness Engineering team looked for innovative ways to cut down on the normal design time and not sacrifice engineering quality. Additionally, our design had to have the ability to be constructed in a very short period of time to accommodate the normal design-bid-build project delivery method utilized by the owner and adhere to the OMPA construction timeline. We also worked hand-in-hand with the ODEQ to streamline the normal permitting process for a quick, one (1) time, and project design submittal approval. Cabbiness Engineering also handled all of the Oklahoma Department of Transportation (ODOT) permitting process for the owner where the new waterline crossed an active state highway.
