Sewage Treatment Plants

The HC Hydroclear range of sewage treatment plants, which we are featuring at Cereals 2022, are suitable for domestic use where mains drainage is not available. They areHarlequin Hydroclear HC6, Harlequin Sewage Treatment Plant, Effluent Holding Tank 1-6 people, Sewage Treatment Plant 1-6 pop, HC6 Hydroclear designed to treat waste so that the water is pure enough to be safely and legally discharged to a watercourse. We will be showcasing the HC6 which is suitable for up to 6 people. There is a range of sizes, from this one – which is the smallest – through to HC50, a size which would be suitable for small hotels, self-catering accommodation sites, campsite toilet blocks, etc.


An alternative type is the CAP range. CAP stands for Continuously Aerated Plant, and it works very efficiently for domestic sewage treatment. This range offers a more compact design for ease of installation. Sizes range from CAP6 (for up to 6 people) to CAP9. However, Harlequin have just increased the range up to CAP18, which is suitable for up to 18 people.

Please ask us for information if you are interested in the larger sizes.


Waste Oil Tanks

This type of tank is specially designed to collect and store waste oil ready for recycling or other specialist waste processing and disposal. The tanks come complete with strainer and a large tundish; and with lockable access lids. There are plastic or steel versions available, depending on what is best suited to your site.

We are featuring the new design ORB1200 from Harlequin at Cereals 2022.

Talk about Tungsten

If you can’t find quite what you are looking for, we can build steel waste oil tanks to order, or even plastic in steel.

These provide the best of both worlds, with an environmentally safe (non-rusting) plastic tank inside a sturdy steel outer shell which provides protection, security and the bund area.
