The Carson Loop Pipeline is a multi-phased project running from the Carson Filter Plant in Pinson, Alabama to the Cahaba Valley distribution system in the south region of our coverage area.  The primary purpose of this pipeline is to provide an alternate source of potable water (filter water) south of town.  The pipeline will ease the demand on Lake Purdy, the Cahaba River, and the Shades Mountain Filter Plant as the sole source of water for this area.

The Carson Loop project involved the installation of approximately 3,650 feet of 36-inch ductile iron cement lined (DICL) pipe and fittings; construction of a 600-foot pipe bridge across the Cahaba River; construction of an access roadway on either side of the bridge; and other related site improvements.

Schoel partnered with Russo Corporation to navigate complex environmental concerns associated with the project.  Construction was scheduled to begin in the Summer of 2023.  The maternity roosting season for several endangered bat species typically occurs in the summer months.  To ensure the project did not adversely affect any endangered species, Schoel conducted a habitat assessment to evaluate whether suitable summer roosting habitat existed within the project area.  The assessment concluded suitable habitat was not present and the report was provided to the U.S. Fish and Wildlife Service for their concurrence.

The physical location of the project demanded careful planning, implementation, and maintenance of Best Management Practices to protect the Cahaba River during construction.  Schoel provided erosion control design, stormwater permitting, and compliance inspections during construction.  Schoel also conducted turbidity monitoring before and during construction to document the effectiveness of Best Management Practices.

Schoel also provided Land Surveying services, which included construction stakeout of the BWWB easement, clearing limits, water main in 50’ increments, and access road centerlines at the bridge approaches.  As-built locations were also collected on the water main as it was installed.
