Septic System Design

Depending on the availability of the public sewer system near a project site, some projects may require a septic system to treat sewage from a home or other building. There are many different types of proprietary treatment systems out there which could be a good fit for your project, but the conventional septic system (septic tank and drainfield) is the most common. The septic tank separates oils and grease from the solids, and effluent from the septic tank is discharged into a leach field or other chamber where it slowly infiltrates into the nearby soil. Many systems are gravity fed, but oftentimes a pump is necessary in a septic design. Each project is unique, not only in the soil characteristics of the site (percolation rates), but also in the site constraints such as topography or limited area.

We will take into account the system demand (estimated sewage flow rates) with the site conditions to design your system. Plans and calculations will be prepared in order to pull a construction permit with the Health Department. We do not do percolation tests (or “perc tests”), but we will coordinate and give recommendations for subconsultants that we work with to do that.
