There will be “minimal disruption to normal traffic flows,” said Irene Haske, spokesperson
for the Stormwater Management Division in the Fairfax County Department of Public Works, and no disruption of sanitary sewer service. People
who live nearby and affected civic organizations are expected to receive
written notification before the project starts.

Approximately 2,237 feet of a sanitary sewer force main along Sleepy Hollow Road between
Dearborn Drive and Malbrook Drive will be rehabilitated. The project
is expected to take two months, “barring unusual weather event or a change by
VDOT,” Haske said.
Workers will use a trenchless,
cured-in-place pipe (CIPP) method to line a 20-inch wide sewer main. CIPP, the
primary method used by the county’s Wastewater Collection Division, is a
jointless, seamless, pipe-within-a-pipe that can increase the useful life of
pipes by up to 50 years, Haske said. CIPP
projects are less costly and can be done faster than the traditional dig-and-replace method.

The existing sanitary sewer line under Sleepy Hollow Road
was installed in 1959, she said. During a preventive maintenance inspection via closed
circuit television, defects were discovered that could cause unnecessary and
costly disruptions or failure of the sewer system.

The project is funded through the Fairfax County
integrated sewer fund, and the county is negotiating the project cost with the
lining vendor, Am-Liner East Inc.
