Blacks Run Interceptor

Wiley|Wilson worked with Harrisonburg-Rockingham Regional Sewer Authority (HRRSA) to develop a master plan to evaluate the major HRRSA interceptors, provide a plan to achieve a 10-year Level of Service (LOS), and support growth in key areas important to HRRSA’s member localities. Existing interceptors range in size from 24” to 54”. The project included preparing a Preliminary Engineering Report (PER) to upsize the main interceptors with 48,700 LF of proposed lines ranging from 48” to 72”.

In response to the environmental concerns, Wiley|Wilson completed a PER for the Division 1 and Division 2 projects identified in the LOS Master Plan. The PER included preliminary design, environmental due diligence investigation, and stakeholder coordination for Blacks Run Interceptor Divisions 1 and 2, which included 11,300 LF of 48” interceptor installation and 2,900 LF of 36” sewer lining and manhole rehabilitation. We also assisted HRRSA in securing state revolving fund financing.

We assisted HRRSA with extensive coordination with both private and local government stakeholders. The project will impact a City park, a major intersection, transfer and recycle station, and a mixed use trail system in the vicinity of James Madison University. In addition to design and construction phase services, we are providing survey, geotechnical investigation, and easement acquisition.
