Leominster, Massachusetts

The challenge

As one of the nation's oldest public-private partnerships, Veolia North America and the City of Leominster have set standards for cooperation, cost savings and an amazing 25 years with only one single lost-time accident. This is a safety milestone few, if any, U.S. or Canadian municipal water facilities have achieved.

The project challenges are:

  • Veolia entered into a design/build and operate/maintain/manage (O&M) agreement with the City of Leominster in 1983.
  • After startup, we phased out the existing wastewater treatment facility, the second activated sludge plant in the United States. Under the current contract, Veolia operates a 4-MGD surface water treatment plant, 1.2-MGD surface plant, chlorination station, two clear wells, a 9.3-MGD advanced secondary activated sludge wastewater treatment plant and nine pump stations.
  • We also are responsible for an industrial pretreatment program, security vulnerability assessment, septage receiving and sludge hauling.

The solution

Innovative solutions:

  • Help city evaluate alternative sludge-disposal options.

  • Manage major rehabilitation of Notown Water Treatment Plant, including replacement of all mechanical and electrical systems and extensive architectural improvements.

  • Provide instrumentation upgrades to Fallbrook plant.

  • Build fully automated, off-site contact tank facility to ensure consistent water quality throughout the distribution system.

  • Conduct a Security Vulnerability Assessment and develop Emergency Response Plan to identify areas of water security risk and recommend mitigation measures.

  • ​Provide hazardous materials and emergency response training for city's water and wastewater facilities as well as routine operations and maintenance training.
