We provide specifications for residential and commercial septic systems. We specify the requirements for conventional septic systems, low-pressure septic systems, aerobic treatment-drip irrigation septic systems and nitrogen-nutrient-reduction-septic-systems.
Nutrient reduction septic systems are designed specifically for environmentally sensitive areas or to achieve reduced setbacks and/or drainfield reductions. Treatment products that we utilize in our designs include HOOT,FAST®, AquaKlear and Singulair Aerobic Systems. These products span a wide application and price range for small to large residential projects as well as small to relatively large commercial sites.
We know that each project site has different needs; some with various difficulties and constraints to overcome. It is therefore necessary for us to be involved in the site and soils assessment in order to understand what alternatives may need to be considered. We are active throughout the project up through system installation.
We design conventional septic systems for residential and small commercial sites where installation space is not an issue. Low pressure septic systems are required when the drainfield square-footage exceeds 1000 square feet. Low pressure systems require a fairly substantial amount of space because of the large drainfield that is required and are labor intensive for the installer. Aerobic treatment (ATU)/drip irrigation septic systems are usually more cost effective. Aerobic treatment drip irrigation systems are often designed when space constraints exist or when a mounded septic system is required. Aerobic treatment drip irrigation systems require significantly less space than a conventional septic tank drainfield system; especially in a mounded scenario. Reduced setbacks to property lines and foundations as well as reductions in the required drainfield square-footage are applied.
We also provide system specifications for nutrient reduction septic systems and performance base treatment systems (PBTS). These systems are required:
1. to achieve a specific nitrogen reduction in environmentally sensitive areas
2. on those sites where severe space constraints exist
3. in order to obtain reduced setbacks to ditches, swales, retention ponds or surface water
4. in order to achieve up to a 40 percent reduction in the required drainfield square-footage
5. if a hardship exists where a conventional septic system cannot be permitted through DOH
