Water Treatment Plant Improvements and Operations Assistance

Orleans, Massachusetts

Overview

Environmental Partners was retained by the Town of Orleans to identify performance limiting factors, develop effective solutions, and design improvements for their 4.5 MGD ultrafiltration membrane treatment facility.  Environmental Partners provided design, bidding, and construction administration, start-up assistance and training services for the improvements project.

Approach

After conducting a flow balance through the facility, and completing various field activities including settleability tests and soil percolation tests, Environmental Partners developed an implementation plan for addressing operational deficiencies.

After construction was complete, a facility audit was conducted to confirm that process equipment was in compliance with the designed scope of work.  Deficiencies were identified, and solutions developed.  In addition, Environmental Partners assisted in the review of SCADA programming and testing.

Services

Environmental Partners completed the design of the following recommended improvements:

  • New reverse flow pump for backwashing the membrane racks
  • New recycle flow pump for the decant chamber
  • New control valve and well pump modifications
  • New source water flow meters at the supply wells
  • New lagoon decant infiltration network
  • Associated instrumentation and electrical work

Construction phase services for the project included construction administration, part-time resident observation, preparation of record drawings, and start-up and training assistance.  The facility improvements were completed in November 2007.

Environmental Partners also provided on-site training and operations assistance including:

  • Development of a Preventative Maintenance Program
  • Preparation of daily water quality testing procedures
  • Preparation of daily chemical usage reports
  • Preparation of a process treatment schematic diagram

In addition, the following services were provided during the plant start-up period:

  • Coordination of performance testing requirements
  • Review and evaluation of SCADA programming under both routine and alarm conditions.
  • Review and evaluation of residuals handling facilities.
