These photographs and specifications are from a three bedroom residential system, that had a failure to its original drainfield. The available area with suitable soils was extremely limited. Design called for a shallow placed pad installed at 12".

The owners requested an AdvanTex Treatment System so as to be able to use the minimum area available, and to increase the residential size from a three bedroom to a four bedroom residence in the future. Installation consisted of a single 1,500 gallon baffled concrete tank to be used as both the primary treatment (septic tank) and the processing tank for the AdvanTex Treatment System. A 1,000 gallon concrete top seam tank was used as the pump chamber, allowing for an 18 hour operating volume and a quarter day reserve capacity.

Specifications:
Peak Sewage Flow:	600 gallons per day
Estimated Percolation Rate:	20 minutes per inch (Class IIa Soils)
Treatment Tank:	1,500 gallon baffled, concrete top seam
Pump Chamber:	1,000 gallon - top seam
AdvanTex Module:	AX-20 - one unit Module is time dosed for 30 seconds and rested for 9.5 minutes
Disposal Method:	Single 20'x 20' Gravel Bed = 400 square feet Bed is time dosed for 1 minute and rested for 90 minutes
