Storm Pipe Relining (Cured-in-Place Pipe Lining) FY 2017

  1. 1. Storm Pipe Relining (Cured-in-Place Pipe Lining) FY 2017 Countywide Project No. SD-000034-018 Department of Public Works and Environmental Services Working for You! A Fairfax County, VA, publication July 2017 1
  2. 2. Project Details Description: The Maintenance and Stormwater Management Division completed 7,883 linear feet (1.5 miles) of stormwater conveyance system cured-in-place pipe lining projects during Fiscal Year 2017. Liners from 15 to 48 inches in diameter were installed within 55 deteriorating storm pipe segments, as old as 68 years. Trenchless technology methods were used on these pipe segments avoiding land disturbance, tree removal, and eliminating conflicts with underground utilities. This method of renewal extends the service life by at least 50 years and minimizes potential failure of the storm pipes in residential areas. In some cases, the soil type and pipe depth would have resulted in excavating near dwelling foundations if the pipe segment was replaced. Project Overview:  Install cured-in-place pipe liners in 7,883 linear feet of storm drainage pipes Project Team:  Design: Jack Meritt, P.E. (MSMD), Pleasants Construction, Inc.  Project Managers: Jonathan Murray (MSMD), Amy Linderman (MSMD)  Contractor: Pleasants Construction, Inc.  Construction Inspection: Tom Cameron, MSMD Maintenance and Stormwater Management Division 2 FY 2017 Storm Pipe Relining
