CULTEC Recharger® and Contactor® underground septic chambers offer an effective wastewater management alternative to concrete galleries and conventional pipe and stone systems, especially for sites with space constraints. The Recharger 150, 180, 280 and 330XL models are high-profile, high-capacity septic chambers. The Contactor EZ-24, 100, 125 and Field Drain C-4 models are lower-profile, lower-capacity chambers, typically used for septic installations with depth restrictions or where larger units may not be approved by the local authority. The CULTEC chambers are accepted in most parts of the US for gravel-less septic leachfields. The Recharger and Contactor series are IAPMO R&T-certified and heavy-duty models meet HS-25 wheel load requirements. They are also included in several nationally accepted hydrology models.www.cultec.com, (800) 4-CULTEC
