Donaldson Crossroads Water Pollution Control Plant Replacement Project

Background

The Donaldson’s Crossroads Water Pollution Control Plant, located at 166 Oakwood Road, McMurray,  serves the southwestern portion of Peters Township, including most of the Route 19 commercial corridor. It provides service to approximately 2,600 equivalent residential households.

The treatment facility was originally constructed in 1962 and its most recent major capacity expansion was in 1982. Portions of the facility are now 50 years old, and in need of major upgrading. The treatment plant is approaching its design organic treatment capacity, and the Authority has established a Tap and Organic Management Plan in order to manage the remaining treatment capacity until a replacement plant can be constructed.

Project Status

  • Act 537 Sewage Facilities Planning: The Pennsylvania Department of Environmental Protections (PaDEP) requires a detailed sewage planning document be prepared documenting the need for plant expansion upgrade projects, and identifying the type and approximate cost of the proposed improvements. The Peters Township Council adopted the Act 537 Sewage Facilities Plan Update for the project in September 2010, approved by PaDEP in March 2011. In summary the Sewage Facilities Plan findings include:
    • Construct a new treatment plant on the adjacent 3.9 acre property abutting West McMurray Road, purchased by the Authority for that purpose.  
    • Provide for a treatment capacity of 1.75 Million Gallons per Day (MGD), using the Conventional Activated Sludge treatment process, with aerobic digestion. The capacity would provide for 500 additional customers during the 20-year planning horizon to 2030.
    • Estimated the treatment plant project costs at $13.2 million in 2010 dollars
    • Projected users fees would need to increase to $47/month for the average users from the existing $35/month to pay for the improvements, based on obtaining a low interest state loan.
  • Special Exception to Zoning: The plant replacement property is Zoned R-1A Single Family residential, with several existing residential dwellings located within 175 feet of the proposed replacement treatment facility. The close proximity of residential dwellings required special efforts to ensure the proposed facility would be concealed from view as much as reasonably possible, and that odors be controlled to the maximum extent possible. The Authority applied for Special Exception to zoning and the Zoning Hearing Board held a public hearing on June 21, 2011. The Authority proposed, among other efforts, the following:
    • The treatment facility would consist of primarily in-ground tanks, with several buildings situated to shield the view of the tanks as much as possible
    • The primary source of odors, consisting or the headworks where the wastewater enters the facility and the aerobic digesters, will include odor control and odor treatment facilities. The headworks will be within a building, and the aerobic digesters will be covered with flat covers, and air from both treatment processes will be treated in odor treatment facilities.
    • All buildings will have a residential appearance, and the security fence fronting West McMurray Road will be black aluminum fence that emulates wrought iron fencing.
    • Noise will be controlled by housing equipment within buildings for the most part, and for the limited equipment located outdoors, if any, would be housed in sound attenuating enclosures.

The Zoning Hearing Board approved the Authority’s application for a special exception. Special Exception Application (PDF) and Zoning Hearing Board Decision (PDF)

  • Treatment Plant Design and Permitting Phase Engineering Services: The design of the replacement treatment facility is a complicated process requiring specialized expertise, and a team of professionals consisting of process, mechanical, structural and electrical engineers, plus substantial input from the Authority’s Management and Operational staff. The Authority developed a detailed Request for Proposal for Design and Permitting Phase Engineering Services, and in October, 2011 invited seven pre-qualified engineering firms to submit competitive technical and cost proposals for the design work. Four firms subsequently submitted proposals.  After reviewing the proposals in detail, which included Management visiting treatment plants recently designed by each of the engineering firms, the Authority Board at its March 27, 2012 regular meeting awarded the Design and Permitting Phase Engineering Services to the project team of Lennon, Smith, Souleret Engineering, Inc (LSSE) and Hazen & Sawyer for the  estimated fee of $951,000. 

LSSE is a local engineering firm that has been providing project engineering services to the Authority since 2000. Hazen & Sawyer is a national engineering firm specializing in water and wastewater engineering. Links to LSSE and Hazen & Sawyer

Project Schedule

 The project schedule has fallen somewhat behind the schedule identified in the Act 537 Sewage Facilities Plan. The following are the current milestones:

  • Complete Plant Design, Obtain All Permits                February 2014
  • Award Construction Contract                                         May 2014
  • Construction Begins                                                        August 2014
  • Construction Complete                                                   June 2016 

Financial

The Authority is using surplus funds to pay for the engineering associated with the planning, design and permitting phases, and thereby postpone borrowing for the plant replacement project for as long as possible. The Authority received a Washington County Local Share Account Grant in the amount of $85,000 towards the facility design.The construction project, when bid in 2014, is expected to cost $12 million. The Authority plans to apply for a low interest state loan for funding the construction phase, and may have to supplement the low interest loan with a revenue bond issue. The Authority will be able to retire the existing Brush Run Plant Expansion Revenue Bonds, original issue 1993, at approximately the same time as the borrowing will be required for the Donaldson’s Crossroads Water Pollution Control Plant Replacement Project in 2014, thereby helping to minimize the financial impacts to our customers. However, since the 2014 borrowing will be approximately 50% greater than the bond issue being retired, a user fee rate increase on the order 34% from today’s user fee is anticipated.
