Septic Solutions installs a variety of systems. The two most commonly used are:
1. CONVENTIONAL SEPTIC TANK SYSTEM
In this system, wastewater flows from the house to the tank where settling occurs. Heavier solids (e.g. organic waste) sink to the bottom of the tank forming the sludge layer. Lighter solids (e.g. grease, soapsuds) float to the top forming the scum layer. The clearish liquid in the middle layer is the effluent.
After settling out for 24 or more hours, the effluent flows out of the tank to the leach field, where it is discharged into the soil for the final treatment and disposal.
Maintenance requires routine pumping of the tank.
This system is preferred if the soil and terrain conditions allow it.
Average cost of installation is $2700. to $3000.
2. AEROBIC, ADVANCE TREATMENT SYSTEM
This system may be needed if the soil is rocky or hard clay, or if the terrain is steep.
Aerobic systems consist of a tank with 3 compartments. Pre-treatment compartment receives wastewater, treats it physically and biologically. The aerator provides mixing and injects fresh air into the Treatment Compartment contents. The wastewater flows through the plant receiving treatment as it flows to the Settling Compartment. Here, fine particles settle and return to the treatment compartment for further processing, leaving only a clear, odorless liquid for final discharge.
For the first 2 years after installation, Septic Solutions provides, free of charge, an inspection service policy, which includes repair, service and maintenance (does not include chorine products). It is recommended that you renew this policy, at your expense, after 2 years.
Average cost of aerobic system installation is $5500. to $7000. depending on soil, terrain and access.
3. A third system, known as EVAPOTRANSPIRATION (ET) may be required in sensitive areas when a conventional system is prohibited and an aerobic system is not appropriate or desired, or when surface water or ground water pollution is a concern.
An ET System is unique in its ability to dispose of wastewater into the atmosphere through evaporation from the soil surface and/or transpiration by plants, without discharging it into the surface water or ground water. In certain cases, the ET system concept offers flexibility by combing seepage with evaporation. This system requires a pre-treatment unit (septic tank or aerobic unit) to remove settleable and floatable solids and an ET sand bed with wastewater distribution piping, a bed liner, fill material, monitoring wells, overflow protection and a surface cover. Vegetation should be planted on the surface of the bed to enhance the transpiration process.
Maintenance in minimal, involving typical yard upkeep and pumping tank as needed (important).
Average cost of this unit is $7000. to $10,000.
