WRF Lift Station

This project consisted of a single microtunnel drive of 310-feet 60-inch diameter x 0.75-inch wall thickness Trinity Press Fit Steel Casing through a composition of poorly graded clean sand, clayey sand, and lean clay, including non-cohesive flowing sands. The microtunnel was installed under a roundabout intersection of Morro Bay Blvd and Quintana Rd. with shafts approximately 20 feet deep, at 12 feet below the groundwater table, and with numerous overlying critical utilities, critical surface improvements, and heavy traffic through the roundabout.
