Bastrop, Louisiana

The challenge

Long-term operations partnership facilitates startup of newly upgraded wastewater treatment facilities.

The project challenges are:

  • The City of Bastrop needed to find qualified operations staff for its newly upgraded wastewater treatment systems to address long-standing environmental compliance problems, regulatory sanctions and odor issues.

  • In 1996 Veolia North America assumed responsibility for Bastrop's wastewater treatment facilities: 4-MGD rotating biological contractor (RBC) tertiary treatment plant, 1.4-MGD post-aerated lagoon plant, 300-mile collection system, eight lift stations and 92-dry-tons per-year biosolids disposal operation.

The solution

Innovative solutions:

  • Employ RBC technology to treat wastewater prior to discharge.

  • Use an accelerated facultative lagoon system to handle average daily flow of 1.4 million gallons and peak capacity of 2.7 million gallons.

  • ​Maintain flow equalization system consisting of one 35-acre and one 5-acre cell; all flow is pumped to the West Pond facility via a 13,000-foot force main for final treatment.
