The award-winning Integrated Pipeline (IPL) Program consists of more than 150 miles of raw water pipeline to connect several North Texas reservoirs in the Tarrant Regional Water District (TRWD) and Dallas Water Utilities (DWU) systems. The program represents a large scale collaboration between the two agencies in an effort to realize significant long-term construction and operational savings for constituents.

LAN designed Section 15-1 which includes more than 15 miles of 108-inch diameter raw water pipeline, spans more than 70 private parcels, and includes 15 stream crossings, 15 road crossings, and one railroad crossing. Seven crossings were designed with tunneling methods which required design coordination with TxDOT, Navarro County, and Union Pacific Railroad.

The project was completed $19 million below the preliminary project budget.
