About Clenviro Ltd
Our Commitment to Quality and Customisation.
As a UK manufacturer of bespoke sewage treatment plants, Clenviro takes pride in its distinctive approach of handcrafting every unit. This unparalleled position enables us to design tailor-made sewage treatment systems that precisely cater to the specific needs of our clients and local authority regulations while adhering to BS EN12566-3 standards.
Our adaptability extends beyond wastewater treatment systems; we also specialise in producing grease traps, pumping stations and other custom fabrications, regardless of their intended application. International clients also enjoy lower shipping costs thanks to our containerised sewage treatment units and ability to design modular tanks that 'plug and play' for easy installation overseas and in off-grid locations.
Our dedication lies in offering our customers a personalised level of service and support, which is often absent in numerous larger corporate entities within our industry. Our enquiries range from people calling to discuss septic tank requirements to complex commercial builds requiring modular units.
Our extensive experience spans several decades, giving us a profound understanding of the field and valuable experience from many different types of projects. Our approach centres around providing accurate and practical advice, empowering our customers to make well-informed choices and consider the hidden maintenance costs associated with other wastewater treatment systems on the market that we do not have.

“We will never compromise just to 'make a sale' as we firmly believe that environmental issues, long term customer satisfaction and our own established reputation are of overriding importance.”
