HKM DRAFT SEPTIC SYSTEM IMPACT STUDY REPORT

The SCCD-NRCS Septic System Improvements program is a local improvements program that provides voluntary, locally-directed, financial and technical assistance for repair or replacement of existing septic systems that likely impact water quality.

During 2003, SCCD was awarded Federal grant monies to initiate a local program geared towards the repair or replacement of faulty septic systems which may potentially be contaminating local streams. 

Many existing homes, new developments, and their associated septic systems within Sheridan County are located in areas with very shallow water tables as is often the case near a stream.  Local regulations require that the bottom of septic system leachfield stone be at least four feet above the seasonal high water table (Sheridan County Regulations for a Permit to Construct, Install or Modify Small Wastewater Facilities and Related Design Standards).  In areas of shallow ground water, this requirement often cannot be met without constructing a mounded leachfield.  Construction of a mounded system ensures regulatory compliance, allows for proper function of the system, and protects the quality of local groundwater.  As part of a demonstration project, SCCD provided funding assistance for a landowner to construct a mounded leachfield system located along the Tongue River.  A video of this project was produced to help educate landowners with similar systems and locations about the proper design and construction of a mounded leachfield system.  This video is available through the SCCD office and the Sheridan County Engineer’s Office.

Funding for the program is provided by a combination of Federal and State grants administered by the SCCD, and landowner contributions..  Federal grants come from US EPA through section 319 of the Clean Water Act and are administered through the Wyoming Department of Environmental Quality.  State grants come from the Wyoming Department of Agriculture.  Approximately 50% cost-share is available on contracts at this time.   

INFORMATION PACKET

The Septic Information packet will provide the homeowner with a starting point on the considerations for installing, replacing, and maintaining a septic system, in addition to providing some basic summaries of alternatives for locations where a conventional system will not protect human health and the environment.  The material presented is for general information purposes only.  Please contact the Sheridan County Engineer’s Office or the Wyoming Department of Environmental Quality for specific requirements regarding any situation.  Not all of the alternatives and requirements presented will be suitable or applicable for all situations.  Nothing in this packet can replace the advice of a qualified professional.
