This subcontract opportunity for the Leucadia Wastewater District involves the installation of cured-in-place pipe lining to rehabilitate existing sewer mains in Carlsbad, California.

The project falls under NAICS code 237110 and requires all participating contractors to maintain valid DIR registration. Interested parties must submit their responses by November 12, 2026, to deliver fully cured and operational lined sewer mains as specified in the project requirements.
