Pipeline Design, Condition Assessment & Rehabilitation


Over the last two decades, LAN has designed more than 700 miles of urban and rural large diameter water pipelines ranging up to 144-inches in diameter. Our team can readily identify and implement the best solutions using the latest technologies and innovations to solve pipeline issues. We are well-versed with the use of PCCP, ductile iron, carbon steel, stainless steel, HDPE, PVC and fiberglass pipe materials, and understand pipelines from the manufacturing process through design, installation, and operation. LAN is one of the few consulting firms that performs detailed structural design of piping materials as opposed to just writing a performance specification. We have provided custom designed fittings for our clients up to 168-inches in diameter. Our team members can provide piping designs in accordance with AWWA or ASME criteria.

Condition Assessment

Pipelines experience extensive wear and tear due to age and improper installation. Assessing their condition is critical to estimating their remaining useful life and cost efficiency. LAN’s “Condition Assessment Plus” is a proactive approach to evaluate the structural integrity of pipelines before failures occur. In addition to the initial condition assessment activities, LAN evaluates system operational characteristics, supports the development of capital improvement projects, identifies future monitoring/assessment requirements, and prioritizes rehabilitation or replacement recommendations.


Recent technological advancements provide opportunities to extend the service life of pipelines with rehabilitation at a fraction of the cost of system replacement. We have evaluated and designed the rehabilitation of more than 1 million linear feet of various water, wastewater, and stormwater pipeline ranging up to 114-inches in diameter. Our experience and knowledge of rehabilitation technologies allows us customize the most appropriate rehabilitation method based on economics, functionality, and public impact.


LAN’s portion of the Integrated Pipeline (IPL) project serving North Texas includes 15 miles of 108-inch diameter pipeline

As Program Manager for the Clear Lake City Water Authority’s Sanitary Sewer Rehabilitation Program, LAN has rehabilitated nearly 50 miles of sanitary sewer.
