DOH / EPA Septic Smart Week
As you may know, in the past several years recognition of on-site systems has been elevated nationally through the
EPA’s SepticSmart program that educates homeowners about proper septic system care and maintenance all year long. In addition, its online resource for industry practitioners, local governments and community organizations provides tools to educate clients and residents about proper care and options for onsite wastewater systems.
The program has been growing nationally and you can look for more detail about it  in your WOSSA Pipeline next week. You can go to the WOSSA website to check out some links and information that you can use to educate your customers with flyers and other informational resources available at no cost.
Our state Governor has signed on and has supported the program with a proclamation declaring next week "Septic's Week" !
Let's go out and raise a stink about it!
