SewTreat – Your Sanitation Specialist!
Sanitation Solutions
SewTreat designs, manufactures, and installs a wide range of innovative and eco-friendly onsite wastewater treatment systems throughout Africa. Our dependable modular plant design has made us a leader in innovative design, value, and service.
Through comprehensive field testing, our wastewater solutions have consistently met and overcome challenges within the African market. Thanks to our proprietary bacterial strain, developed for use in easy-to-install modular units, our plants successfully transform wastewater into clean, clear, odourless treated water.
We specialise in biological wastewater treatment plants through our superior biological technology, developed in-house by our team of experts. Our treatment process is based on return-activated sludge technology, incorporating submersed aeration media. The enhanced bacterial action ensures a highly effective treatment process with a very small footprint, low capital requirements, and minimal maintenance.
All plants are constructed at our 2,500m² manufacturing facility, cold commissioned, and fully tested to ensure quality and efficiency before delivery to the site for installation.
