Large Diameter Pipelines
L.H. Woods & Sons has been constructing large diameter water, sewer and storm drain pipelines since 1958. We have built some of the largest pipeline projects in California including over 13 miles of the Inland Feeder Project for the Metropolitan Water District of Southern California. L. H. Woods is known for the superior quality of its work, having almost zero call back for warranty work.
We have been rehabilitating large diameter pipelines since the late 1980’s. LHWS has rehabilitated over 30 miles of pipelines for its clients. Since the first rehabilitation project was completed, we have work to improve the design and have manufactured several specialized pipe carriers to install new steel pipe inside of the existing deteriorated pipelines. Our fleet of pipe carriers has the ability to install a variety of pipeline diameters and lengths and permit the installation of pipe on steep grades and through sharp corners. Our experience in rehabilitating pipelines is second to none in the United States.

Our expertise includes installation of the complex mechanical systems of a pump station to the installation of specialized quaga muscle filtering systems. We are experienced in constructing subterranean pump stations as well as above ground facilities.
LHWS has successfully completed numerous design/build projects for its clients. The design/build process has permitted us to develop construction solutions for our clients that address all project complexities while saving money and time to complete the projects. L H Woods takes pride in its ability to develop innovative solutions to complex problems and its ability to effectively work with its clients to develop the ultimate project design and to efficiently construct the project.
