A Modern Solution - Sewage Treatment Plant

All sewage treatment plants operate on a common principle: fostering an environment conducive to the production of aerobic bacteria. The introduction or availability of air prompts the development of microorganisms, facilitating the breakdown of sewage in diverse treatment and settlement zones. The effluent quality from top manufacturers consistently exceeds 95%, ensuring clean effluent throughout the sewage treatment process.


Infinity Environmental excels as installers of leading package sewage treatment plants, adhering to the latest standard EN 12566-part 3. As independent installers, we are committed to recommending the most effective product on the market to address your off-mains drainage challenges.
