Onsite program records project nearing completion

 
DEQ’s Onsite Program is wrapping up an ambitious project to put more than 100,000 files online. The project will benefit real estate professionals, septic installers and homeowners searching for septic records in the counties where DEQ administers its onsite program. The online files provide information on the types, sizes and locations of septic systems across the state and will be free to the public. The program expects to have all files online by the end of March.
