No. A limited number of drainfields are not located in the CBPA. If you like, you can provide information to Hanover County documenting that your on-site sewage disposal system is not located within a CBPA or call the Department of Public Works at 804-365-6181 for assistance.
Also, a few systems have plastic filters permitted by the Virginia Department of Health. These systems are also not required to pump-out every 5 years because they routinely require more frequent maintenance. If you have an approved plastic filter, you may submit evidence and request being removed from the program. The Virginia Department of Health does not have a list of systems with approved plastic filters. Regular pumping and maintenance will save you money and protect the environment.
