How Evaluations Work

Your soil is the most important factor in determining if your property is suited for an on-site sewage treatment system. Your soil evaluation is a prerequisite for any on-site treatment system design.

The soil evaluation examines soil properties and site characteristics that are critical in site selection, design, system selection and installation. Some key soil properties and site characteristics include permeability, seasonal high water, depth to bedrock or other restrictive horizons, and slope.

Soil evaluations provide repeatable results regardless of the season, soil moisture and weather conditions.

Determining soil drainage is critical in evaluating sites for the treatment and disposal of effluent. This process can identify limiting layers that inhibit water movement and the depth that they occur. With this information, systems can be designed and sized accordingly.

In many areas the soil profile consists of gravelly material, gravel, flagstone and, in some areas, shallow bedrock. A soil evaluation can determine if enough soil material is present for treatment and disposal of effluent. This information is critical for groundwater protection.

Your On-Site Soils evaluation also includes:

A computer generated site map locating the soil boring or soil pit locations, present building site features, present drainage patterns, and any restrictive areas (existing wells, ponds, streams, parking areas, livestock areas, etc.) Also, if known, the site map will locate future buildings, any future well site and the property lines.

If needed, several sites on your property will be evaluated. This
allows flexibility in determining the most favorable location for your absorption field.

We will provide a site photo for each project. The photo is for general site review purposes and to assist your county in the review process.
