Delta 4 is a sewage treatment system from Clearwater’s Delta Range that’s fully compliant with building regulations and certified to BS EN 12566 Part 3. The tank will treat effluent from a domestic or commercial property to a certain level for domestic applications, tested for a specific standard. Thanks to fluidized fixed-film biozones, Delta sewage treatment plants are made more efficient and are quieter when in operation. The inclusion of biozones also helps to make the effluent cleaner, allowing the effluent to be discharged into a public watercourse when permission is secured from the various authorities involved.

Desludging for this sewage treatment plant takes place very easily thanks to an easy access chamber underneath the lockable cover. Minimal maintenance is combined with a shallow excavation thanks to a low-profile tank to make this Delta 4 sewage treatment plant extremely easy to install and to have.

This Delta 4 sewage treatment plant is designed for domestic properties and will treat the effluence of up to 25 people. It has a 750mm inlet invert.
