The Indiana State Department of Health (ISDH) is reminding Hoosiers to maintain their septic systems as part of SepticSmart Week, a national observance designed to educate homeowners and communities about the importance of caring for septic systems. Gov. Eric Holcomb has declared Sept. 18-22 SepticSmart Week in Indiana as part of the observance. You should avoid pouring fats, grease and solids down the drain, monitor water use and spread out laundry and dishwasher loads throughout the day.
