The Regional Residuals Facility (RRF), located at HRSD’s Nansemond Treatment Plant, was developed and constructed to receive and process residual material captured during maintenance and cleaning operations of the public sanitary sewer collection system within the HRSD service area. It is intended to receive solid residuals, with minimal liquid, that are non-hazardous by definition and can be easily dewatered using gravity separation. 
 
Residuals generated from maintenance and/or cleaning of sanitary sewer systems are regulated as liquid industrial waste by the Virginia Department of Environmental Quality (VDEQ). Collection system maintenance and cleaning results in liquid and solid residue that contains pollutants that can harm human health, degrade water quality and aquatic habitat, and impair ecosystem functions. Regular and frequent cleaning of wet wells and sanitary sewer systems are required for proper operation of the infrastructure to reduce sanitary sewer overflows (SSOs) from occurring due to blockages or leaks in the system. Elevated bacteria levels impair water quality and can lead to restrictions on the use and enjoyment of natural resources such as shellfish beds and swimming areas. Understanding the sources of these pollutants and their impacts can help inform municipal planning and assist in identifying priority goals and objectives when managing and/or operating a sanitary sewer collection system.
 
The objective of this Best Management Practice (BMP) is to provide an understanding of the facility and its operation and administration, assist with training, and promote guidance for the disposal of sanitary sewer system residuals from municipal and HRSD collection systems. Every RRF user is required to follow the requirements of the BMP when using the facility.
