BrandywineBrandywine Hundred Sewer Rehabilitation Utilizing UV CIPP; New Castle County, DE

To service the sanitary sewer needs of its 118,000 residents, New Castel County, DE maintains over 150 pumping stations, 43,000 manholes and 1,700 miles of sewer main pipes according to the counties website.  A significant concentration of the counties sanitary sewer infrastructure exists within the area commonly known as Brandywine Hundred.  This area, which includes the state’s oldest and largest port and industrial sectors, also claims one of our nation’s oldest operating sanitary sewer conveyance systems. As the system has aged, sources of ground water and surface water run-off have found its way into this system as inflow and Infiltration (I & I) causing a large problem in reoccurring basement overflows as well as unintended discharges into local waterways during storm events.  This event is commonly known as sanitary sewer overflows (SSO).  In 2002, through the mandates of the Federal Government’s Clean Water Act, the State Department of Natural Resources and Environmental Conservation (DNREC) issued a Secretary’s Order leading toward a goal set by the county’s Special Services unit to reduce SSO’s by 35%.  Since 2009, Abel Recon has employed the UV “Cured-In-Place-Pipelining” technology (UV CIPP) to provide structurally rehabilitation and renewed water tightness of over 195,000 lineal feet of sewer main pipe to seal out the I&I and bring about a solution to New Castle County’s failing infrastructure situation.  As a result of the efforts of Abel Recon and other methods employed, progress studies conducted by the county’s consulting firm show a reduction of approximately 28% in I&I.  Abel Recon is proud to have a role in this success.
