Attenuation & Soakaway Tanks

Hydro WMS’ offer a unique approach utilising our extensive industry experience in design, supply and installation of SuDS solutions.

Our in-house design team allows us to provide a tried and tested practical approach to drainage design. We can often identify cost savings by rationalising designs, reducing storage volumes or simply selecting the most appropriate product.

Hydro WMS can model drainage networks and offer Professional Indemnity (PI) insurance allowing us to take on design responsibility.

We have a range of products and solutions to suit all design criteria, this includes:

  • Shallow installation
  • Deep installation (5m+)
  • Irregular shapes
  • Prefabricated
  • Inspection and maintenance

All Hydro WMS attenuation tanks are fully welded using proprietary wedge welding techniques in accordance with CIRIA guidelines.

Hydro WMS soakaways are modular systems designed and installed utilising the same high quality injection moulded units combined with a non woven geotextile.

Flow Controls

Including Orifice Plates

A Vortex Flow Control Unit or Orifice Plate is designed to regulate the flow of water before it discharges into the water course or sewage network. Choosing the right Flow Control can have a dramatic effect on the volume of water required to be stored on site.

Hydro WMS offer a range of Vortex Flow Control Units and Orifice Plates which can be tailor made to suit any application. Hydro WMS can check the suitability of each Flow Control using industry standard software.

All Vortex Flow Controls supplied by Hydro WMS are manufactured to the highest standards using Grade 304 or 316 stainless steel.

Sewage Treatment Plants

Independent systems

For any application, domestic, residential, commercial or industrial, where there is no access to a mains sewer by gravity or by pumping, Hydro WMS sewage treatment plant provides an extremely safe, efficient, reliable and cost effective solution to sewage disposal.

All treatment systems meet and exceed Environment Agency and all regulatory requirements for process efficiency and final effluent quality.

The design of the system takes into account all those aspects which we have found to be important to domestic and commercial customers alike. Products are tested and CE certified to BSEN12566-3, which achieving industry leading test results in both process and structural efficiency and, as such, has achieved a worldwide reputation for quality and efficiency.

For gravity systems there are no mechanical components within the treatment plant itself thereby ensuring that maintenance is minimal, simple and safe.

Pumped versions are available, negating the need for a separate pump chamber.
