Combination system reduces footprintProblemThe drainfield had failed on the onsite system serving a three-bedroom home in Juneau, Alaska. The lot was too small for a replacement drainfield, and direct discharge was not an option.SolutionSloan Swendsen, co-owner of Juneau Septic Services, installed a Platinum submerged aerated filter for secondary treatment with Puraflo peat fiber biofilters from Anua. The aerated filter has a pump package in the clarifier, eliminating the pump tank and reducing the footprint. The two biofilters, on an in-ground gravel dispersal bed, further reduced the footprint.ResultEffluent averages 5 mg/L BOD and 5 mg/L TSS with 95 percent fecal coliform
