Onsite Wastewater Regulations Database

Want to know the regulations for onsite wastewater systems in your state? Now you can search the National Environmental Services Center Database online.

This collection can help customers seeking information for a particular state or those who want to compare regulatory structures between states. It is particularly useful to states seeking assistance in revising regulations.

The Regulations Database allows customers to review copies of onsite wastewater regulatory documents and helps the NSFC determine if it is meeting the growing and changing needs of the regulatory community. It should be noted that while information from the database is provided to customers, the NSFC does not interpret regulations for customers. For additional information, please contact your state's onsite wastewater regulatory contact. A list of contacts is on the Web at National Environmental Service Center Contacts.
