HRSD stands for the Hampton Roads Sanitation District. They are the regional processor of the wastewater produced from your home.
No, they are entirely separate. They accept the wastewater from Hampton and process it at their own facilities. You receive a bill for their services directly from the HRSD office every two months.
It covers the cost of processing your wastewater once it is delivered to the HRSD facility through the City sewer system.
No they do not. All repairs, maintenance, opening of stoppages, construction, and monitoring of the sewer system is done by the City of Hampton.
Their customer service telephone number is (757) 877-2019 and the general office number is (757) 460-2261.
Items that will clog the sewer system such as rags, sponges, small toys, any household chemicals, automotive chemicals, flammable liquids, or paints. These materials are not only a danger to people, but cause processing problems at the HRSD facility. Dispose of all your household chemicals safely through Hampton's collection program.
Cross connections are ones between the sanitary sewer system and the storm water system and are not allowed, ever. Wastewater must be treated at HRSD facilities and storm water is just rain run-off that goes directly to the Chesapeake Bay through a ditch system.
