Residential Wastewater Treatment System
CHERTS is a compact, prefabricated biological wastewater treatment system designed specifically for installation after existing septic tanks to provide advanced secondary treatment and enable safe water reuse. It is an ideal solution for homes and small communities without centralized sewer systems, particularly in areas where groundwater contamination is a concern or where water resource recovery is desired.
By integrating CHERTS downstream of a conventional septic system, property owners can upgrade from basic primary treatment to a complete nutrient-removal solution - achieving effluent quality suitable for irrigation, landscaping, toilet flushing, or groundwater recharge.
Product Highlights
Perfect Retrofit Solution
Easily connects after existing septic tanks to upgrade treatment performance without replacing the original system.
Groundwater Protection
Reduces BOD, nitrogen, and suspended solids to prevent leaching and protect aquifers from nutrient pollution - a major concern in rural and suburban areas.
Enables Water Reuse
Produces high-quality effluent suitable for non-potable reuse applications, helping reduce freshwater demand.
Compact & Efficient
Treatment capacity options from 500–1500 gal/day (2–5.7 m3/day) per unit, ideal for single-family homes, vacation properties, or small communities.
Low O&M & Smart Monitoring
Equipped with integrated aeration, automated control, and remote monitoring for low-maintenance operation (sediment removal ~every 2 years).Detailed Specifications
