Don't forget to contact Digger's Hotline at least three (3) business days prior to any excavation.
 
 
Over 21,000 homes and businesses in Vilas County are served by septic systems.  Septic systems work by first separating liquids; solids; and fats, oils, and grease in a septic tank.  The liquid is then moved through a filter and moved by gravity or a pump to a leach bed where it is disbursed into the ground.  The leachbed material and native soils clean the liquid effluent before it is returned to the groundwater.  For more information on how septic systems work, contact the Vilas County Zoning & Planning Department at (715) 479-3619.
