Delta 3 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 3 sewage treatment plant extremely easy to install and to have.

Delivery Information


The delivery of a tank can be confusing as each manufacturer offers a slightly different service and lead time. Please refer to our Delivery Information page.  Standard tank deliveries are "kerbside" which means the tank will be delivered to the kerb only and not positioned further. Should you have specific delivery requirements or restrictions, please contact us to discuss.


Most accessories will be delivered within 1-3 working days. If you require them quicker, we can on occasions offer a next day service (please contact us to discuss). If the item(s) are out of stock we will advise you of the expected lead time and you will of course have the opportunity to cancel with a full refund.
