Our robust selection features sludge tanks, settlement tanks, and mixing tanks and each equipped with self-draining functionality for enhanced maintenance ease.
Popular among sewage treatment plants, our tanks ensure optimal efficiency and superior performance across various applications. Choose Camplas Technology for reliable, high-quality solutions that deliver lasting value.
Fully customisable
BS4994-1987(formerly BS4994-1973) with a minimum factor of safety of 8/1
Custom built tanks from 10 to 300 cubic metres capacity and in diameters from 2500 to 4000mm with flat, dished or conical bases
Our tanks feature a dome-based design with a Geodesic-shaped base, which facilitates complete drainage without the ‘bridging’ often seen in conical silos. This design not only enhances the aesthetic profile with its lower and more streamlined appearance but also includes a supportive skirt to ensure stability and prevent tipping.
Standard tanks are between 30 and 100 cubic meter capacity and 3500 mm internal diameter with varying heights, but other shapes and sizes can be custom built for specific applications. Extensively used on effluent treatment plants for settlement of sludge and suspended solids, food and chemical process plants for mixing of batch quantities and fish.
Camplas are proud to have played a small part in the Hardington Mandeville project for Wessex Water. For more information please click this link https://www.wessexwater.co.uk/news/rural-upgrade-helping-to-keep-it-clean-in-somerset

Camplas manufactures GRP sewage treatment tanks in capacities from 10 to 300 cubic metres. Every tank is built to order, with diameters from 2.5 m to 4 m and the height set to suit the required capacity and the space available. Vertical tanks are supplied up to 200 cubic metres. For capacities between 200 and 300 cubic metres, tanks are manufactured in a horizontal configuration and can be installed above or below ground.
Camplas sewage and sludge tanks are built with a dished base rather than a flat or cone-shaped one. Sludge settles and thickens over time; on a flat base it collects in the corners and has to be cleared by hand, whereas on a dished base it moves continuously towards the central sump and drains completely when the tank is emptied. The smooth curved profile also stops material sticking to the walls or bridging across the outlet, which can be a problem with steep cone bases. The tank sits on a supporting skirt, which gives a stable footprint and raises the sump clear of the base for the outlet connection.
Yes. As sludge settles, the clarified liquid (liquor) collects above it, and a set of decant valves allows this liquor to be drawn off at different levels as the sludge thickens. Decant valves can be built into the tank at the heights required for your process, so the liquor can be removed in stages without disturbing the settled sludge. This reduces the volume left to be dewatered or tankered away, which lowers handling and disposal costs. The number and position of the decant points are specified for each project.
Camplas sewage treatment tanks are available with a 600 mm diameter side manway with a bolted cover, or a roof manway with a hinged cover.
Yes. Camplas tanks can be designed to accept your chosen mixer, with the roof and supporting structure engineered to carry its weight and operating loads. Camplas has built stirrer-mounted tanks for mixers of up to 1 tonne, including the steel support structures. Provide the mixer specification (make, model, weight and mounting details) at the quotation stage and the tank will be designed around it.
Camplas sewage and sludge tanks are built to order, so they can be specified with a range of options. These include side or roof manways, decant valves at specified levels, mounting for a mixer or stirrer, additional flanged connections for inlet, outlet and overflow, access ladders, platforms and handrails, odour control vents, double-skin construction with leak detection, insulation, and any RAL colour.
If you have a requirement that is not listed here, please contact us with your specification.
Camplas sewage treatment tanks are designed for a 25 year service life. In sewage and sludge service, hydrogen sulphide from the settled sludge forms sulphuric acid on the tank walls and roof, which attacks concrete and corrodes steel; tanks in those materials depend on protective linings that have to be checked and renewed. GRP does not rust and is resistant to sulphuric acid, so a Camplas tank keeps its strength without relying on a protective coating.
Routine maintenance is limited to periodic inspection of the tank, fittings and seals.
