A8-18075-DA – LA 27 Water Line Replacement
R P Construction completed the LA 27 Water Line Replacement Project for Beauregard Parish Waterworks District No. 2 to improve reliability and capacity within the district’s potable water distribution system. The project involved replacement and installation of new water transmission infrastructure along the LA 27 corridor. Work included installation of new 12-inch PVC and HDPE water mains, service line connections, valves, hydrants, and associated system components. Trenchless construction techniques, including Horizontal Directional Drilling (HDD), were utilized to install portions of the pipeline while minimizing impacts to roadway traffic and surrounding infrastructure.
Project Overview
The LA 27 Water Line Replacement Project (MA Project No. A8-18075-DA) involved replacement and upgrading of an existing potable water transmission line serving the Beauregard Parish Waterworks District No. 2 service area. The project required furnishing all labor, materials, equipment, supervision, and construction services necessary to construct the new water main and integrate it with the existing distribution system. Construction included installation of approximately 15,000 linear feet of 12-inch PVC water main along with additional segments of 12-inch HDPE water main. These improvements were designed to increase system reliability and improve water delivery capacity within the district. The project also required installation of new gate valves, mechanical fittings, tapping sleeves, thrust blocks, and fire hydrants. Existing water services were transferred from the old main to the newly installed pipeline, and multiple connections were made to existing water mains of varying sizes throughout the system. Portions of the pipeline installation were completed using Horizontal Directional Drilling (HDD) to safely install water mains beneath roadways and other sensitive areas where open trench construction was not feasible. Additional work included relocation of existing fire hydrants, installation of service lines, system testing, and disinfection of the completed water mains. Site restoration activities included turf reconstruction, fencing repairs, installation of marking posts, and final grading to restore disturbed areas. Upon completion, the project provided a modernized transmission line that improved system reliability and water distribution efficiency for customers served by Waterworks District No. 2.
Key Highlights
- Installed approximately 15,000 linear feet of 12-inch potable water transmission main to improve system capacity and reliability.
- Utilized Horizontal Directional Drilling (HDD) and conventional trench construction to install pipelines along the LA 27 corridor.
- Installed system infrastructure including gate valves, fire hydrants, service connections, and mechanical fittings to integrate the new main with the existing distribution network.
Delivery Challenges
- Performing pipeline construction within an active highway corridor (LA 27) while maintaining safe traffic operations and minimizing disruptions.
- Integrating the new transmission main with multiple existing water mains and service connections across the system.
