Conner Creek CSO Control Facility – LGC built the CSO control facility to mitigate environmental concerns and satisfy Federal specifications for release into the Detroit River. The project consisted of temporary retention systems, installation of a 30M gallon reinforced CSO detention basin, pile-supported foundations with reinforced concrete and influent channels connecting the basin to existing outfalls.

Rehabilitation of Existing Circular & Non-Circular Sewers – Reaching depths exceeding 90 feet, we located and repaired construction joints in all 4 walls of the 6 low-lift discharge flumes of the Northeast Water Treatment Plant. With precision accuracy, we pressure-injected them with polyurethane grout. Completed project totaled 3.3k LF of discharge flumes.

Design-Build Outfall Rehabilitation – Rehabilitated outfalls within the ageing 80 year-old infrastructure system, so they properly discharged and continued to run over a period of time.

The work involved ~500 hydrants within an accelerated completion time, to include the restoration of pavements and streets with original landscaping in each of the affected areas.
