    Integrated Pipeline Project– Tarrant Regional Water District (TRWD)

    LAN played a key role in the Integrated Pipeline Project (IPL), specifically as the lead designer for Section 15-1. The IPL is a major raw water conveyance system developed by the Tarrant Regional Water District (TRWD) to deliver over 350 million gallons per day to the Dallas/Fort Worth Metroplex. The full program includes approximately 150 miles of 108-inch diameter pipeline, multiple pump stations, pressure reduction facilities, and complex interconnections with existing infrastructure.

    Northeast Transmission Line – City of Houston

    LAN served as Program Manager and Technical Advisor for the City of Houston’s Northeast Transmission Line (NETL) project—the largest water transmission project in the city’s history. The NETL was developed in response to the Harris-Galveston Subsidence District mandate to reduce groundwater pumping and mitigate land subsidence and flooding risks in the Houston region. The project was divided into 13 construction segments, each with unique challenges, including 56 tunneled crossings totaling approximately 13,400 linear feet under major highways, railroads, and bayous. 

  • Surface Water Transmission Program – City of Houston

    LAN has served as Program Manager for the City of Houston’s Surface Water Transmission Program (SWTP) for more than 30 years. The SWTP is a $660 million, multi-decade initiative designed to transition Houston’s water supply from groundwater to surface water, reducing land subsidence and supporting the region’s long-term water needs.
