Wastewater Historical Information . Septic Stats by State
The National Onsite Demonstration Program (NODP) used this historical information from their integrated database to encourage the use of alternative, onsite and wastewater treatment technologies. The NODP program helped to protect public health, ensure water quality, and sustain the environment in many small and rural communities. The topics of onsite wastewater information provided about each state are: contacts, regulations, statutes and state codes, quick facts, and septic stats, onsite demonstration programs, and onsite management communities.
