Lee Creek Water Treatment Plant

Lee Creek Water Treatment Plant

Location: Fort Smith, Ark.

Client: City of Fort Smith

Completion Date: 2001

Burns & McDonnell worked with the City of Fort Smith to provide for the long-range water supply and treatment needs of the city and its wholesale customers. It was anticipated that increases in water demand would exceed the capacity of the two existing treatment plants before completion of the new facilities. In order to meet the short-term water demand, Burns & McDonnell completed a study to optimize water production at the Lee Creek Plant, which uses a lake for raw water supply. Peak production capacity grew from 15 million gallons per day (MGD) to 23.5 MGD.

Plant improvements included raw water pumping, flow metering, flow splitting, clarification, chemical feed, clearwells and high service pumping. The filters were successfully tested and approved at higher loading rates. As a result, the cost of installing additional filters was avoided.

Burns & McDonnell completed project design, received bids and completed construction in time to provide the additional capacity needed during the construction phase of the new water supply at Lake Fort Smith.

  • Optimization increase in plant capacity to meet demand
  • Compliance with drinking water regulations
  • Filter testing

Burns & McDonnell:

  • Determined the rated capacity of each unit process on the basis of state regulations.
  • Determined the actual capacity of each unit process based on plant operating records, interviews with operation personnel and on-site observations.
  • Determined the plant modifications required to provide sufficient capacity to meet water demand until the city's new water source and treatment were brought online.
  • Determined plant modifications required to comply with proposed and anticipated drinking water regulations.
  • Provided a site plan and general arrangement drawings of proposed improvements, an opinion of probable cost and a schedule for implementation.
