CULTEC Contactor® and Recharger® septic chambers replace conventional pipe and stone or concrete leachfields. They may be installed in trench or bed configurations according to acceptance by local regulations. Contact area is maximized by the fully open bottoms, perforated sidewalls, and the use of CULTEC No. 410. Filter Fabric. Units may be configured in trench or bed installations using gravity feed or pressure distribution. Due to their greater contact area, CULTEC chambers are commonly allowed to reduce the overall system sizing requirements up to 50% when approved by the local authority.

CULTEC offers the largest variety of chamber sizes and therefore is able to accommodate almost any site parameter.
Sizes range from 8.5” to 30.5” tall. Leaching capabilities range from 3.03 ft²/ft to 9.8 ft²/ft.*
