Section 12VAC5-570-170 - Sewage treatment

A. Public or municipal sewerage systems and treatment works should be used if there is reasonable access to sewers. When such municipal means of disposal are not available, the owner shall have designed and installed an approved sewerage system or treatment works. An approved sewerage system or treatment works is (i) a system for which a certificate to operate has been issued jointly by the department and the Department of Environmental Quality, (ii) a system approved by the Department of Environmental Quality in accordance with Title 62.1 of the Code of Virginia, or (iii) a system approved by the commissioner in accordance with Title 32.1 of the Code of Virginia.

B. The sewage design flow for each slip shall be 25 gallons per slip per day. Where dry storage is provided, each dry storage space shall be equivalent to one-third of a slip. The sewage design flow for each live-aboard slip shall be 50 gallons per slip per day. When marinas or other places where boats are moored are constructed in conjunction with another structure or facility, the sewage design flows prescribed in this section shall be added to the sewage design flow governing the associated structure or facility.

C. For marinas or other places where boats are moored that have a boating access facility, the design sewage flow shall be increased by 10 gallons per day per boat trailer parking space.

D. The division may approve a reduction in the sewage flow requirements specified in subsection B of this section if the owner provides documented flow data sufficient to justify the reduction.
