We offer a wide variety of Sewage Treatment Systems and Plants including the industry-Leading Harlequin Hydroclear, Klargester Biodisc, Klargester Biotec, Conder ASP Treatment Plants. All of our Sewage Treatment Plants meet or exceed all current legislation including the General Binding Rules 2020.
A Sewage treatment plant works by removing contaminants from wastewater and household sewage by circulating air within the unit to encourages the growth of bacteria to break down the sewage. They are designed to produce cleaner and more environmentally friendlier effluent. Domestic sewage treatment plants are used when it is not possible (or legal) to install a compliant septic tank.
