Protecting the community's infrastructure while improving the environment through one of the industry's most comprehensive asset-management programs.

CHALLENGE

In 2005, the Gresham City Council chose to partner with Veolia North America based on our experience, bench strength and track record of elevating programs to best-in-class status. The City Council needed a partner who could implement a world-class wastewater program, with the goal of protecting Gresham's infrastructure assets while improving the environment for this community of more than 100,000.

SOLUTION

  • Under a seven-year, $21-million contract, Veolia manages all operations and maintenance of the city's 20 million-gallon-per-day sludge-activated wastewater treatment plant, a beneficial use biosolids management program, industrial pretreatment program analyses, cogeneration operation, laboratory services and 9 lift stations.
  • Purchased PC-sized server to interface with the plant's SCADA system to assist operators with plant monitoring and process controls.
  • Designed land-application program that meets state and federal criteria for disposal by applying stabilized sludge to agricultural land as a soil amendment. As a result, the need for onsite biosolids storage has been significantly diminished.
  • Provides the Gresham community with innovative operations and environmental programs that have earned numerous regional technical awards and recognition.
  • Implemented comprehensive asset manage program designed to preserve and protect the city's valuable assets.
  • Installed video cameras throughout gravity belt press area and streaming current detectors to reduce manpower requirements and improve response to chemical feed areas.
  • Made numerous lift station improvements that include intrusion alarms, enhanced instrumentation and controls, upgrades of backflow prevention equipment and removal of out-of-service equipment.

RESULTS

  • Anticipated to reduce capital maintenance and replacement costs of the city's assets by 15 to 25 percent over the term of the agreement, saving Gresham several million dollars for other municipal priorities.
  • 75 percent anticipated reduction in preventive maintenance by basing service on equipment run-time rather than calendar time,
  • Cogeneration power system generates half of the plant's daily power usage, saving approximately $18,000 per month.
  • Green-tech system generates electricity on site by using the methane gas that is produced naturally by the wastewater treatment process, thereby reducing demand from the local power grid.
  • The green-tech system has reduced emissions at the facility and saved the Gresham community $625,000 - and counting - since it commenced operation in November 2005.
  • Recognized numerous times by the National Association of Clean Water Agencies and the Water Environment Federation-Pacific Northwest Clean Water Association.
  • Earned Julian Award for Sustainability (2006) from the American Public Works Association.
  • Earned the GREAT Business recognition from the city for our resource conservation efforts - energy usage, waste reduction, recycling and stormwater and wastewater practices.
  • Nationally recognized with the 2008 Public-Private Partnership Award from the National Council for Public-Private Partnerships (NCPPP), an award that recognizes best practices and innovative approaches.
  • In 2013 received Energy Savings Recognition from the Energy Trust of Oregon.
  • Earned the Silver Award (2011) by the National Association of Clean Water Agencies, an award presented to wastewater facilities that have had five or less National Pollutant Discharge Elimination System permit violations during a calendar year.
  • U.S. Conference of Mayors and Pacific Northwest Clean Water Association each honored facility with the Sustainability Award (2012).
