The City of Tulsa has identified over 120 miles of 2-inch waterlines servicing the customers around the city. These 2-inch waterlines require updating due to their age and inability to supply fire hydrants with adequate flow and pressure. The City divided the replacements into smaller localized project areas of approximately 2 miles of waterline each. CGA Engineers was awarded a section of the project in the neighborhood between 41st and 45th and Riverside and Peoria in Tulsa, OK. The project goal was to replace the existing 2-inch with 6-inch waterlines
Our first priority was to survey the areas where construction was to take place. This was accomplished with or in-house survey crew. The crew surveyed approximately 10,00 feet of streets in the neighborhood. We used this survey and the City as-builts as a base to design the new waterline.
In the design process of the waterline, care had to be taken to avoid encroaching on property not included in the right of way. The City had also given us the guidelines not to replace driveways and to avoid digging under drip lines of trees. We accomplished this in our design by providing for the waterline to be bored under the existing driveways and trees wherever possible. Our design also took into account construction activities. We placed valves and fittings in such a way as to make constructing the job easier for the crews.
In total, the design included 11,200 feet of 6-inch waterline, 17 three-way fire hydrants, and serviced 251 customers in the neighborhood.
Estimated Construction Cost - $1,150,000.00
