Stormwater Basin Construction

At the former Edwards Generating Station, BCC constructed a new stormwater basin to reroute water from the soon to be capped coal ash pond. This project included erosion and sediment control, surveying, and excavation for the basin, along with installation of a pretreatment basin designed to capture sediment and debris before stormwater enters the main basin and associated gate valves. The team also managed unusable coal from our previous project at Edwards Generating Station by stockpiling it with other unsuitable materials at another portion of the site outside of the basin design. The BCC team provided engineering support for basin redesign to improve basin performance. Following construction, the site was restored and stabilized through seeding, ensuring long-term environmental protection and regulatory compliance.

​

The scope of work included:

​

• Relocated 20,000 CY of unusable coal

• Excavated 57,000 CY of soil

• Installed stormwater piping system

• Installed pretreatment basin and gate valves

• Removed existing asbestos discharge pipe

• 9.5 acres of seeding
