In reviewing our request for a surface water attenuation system SDS were able to custom engineer a smart solution that also met our requirement to recycle water on the site. SDS became the clear choice for us once we understood that they would manufacture all of the elements in-house rather than out-source them and could supply so many of the components required.
Take Control of Water

Water is the world’s most precious asset – but also our greatest challenge.
As we face the growing pressure of water scarcity and unpredictable climatic events, water security is no longer a nice-to-have, it’s a necessity.
SDS Infrastructure’s overarching purpose is to deliver total water security.
Whether that manifests itself in the mitigation of drought through the conservation and recycling of water, in the provision of safety from danger to life and livelihoods through flood prevention, or in the protection of our environment and ecosystems by the treatment of pollutants, our mission holds true.

What People Say
Despite the very short timeframe in which to complete the installation of the drainage system, the unfavourable weather and the requirement to work under floodlight, we were able to rely upon SDS, once more, to get the job done in time and to the high standards we expect and which they consistently deliver.
The combination of diligent project procurement and planning saw a pioneering excavation, final assembly and installation period of only 11 days. Off-site manufacture and a studious design phase ensured reduced health and safety risks and improved environmental credentials over the construction and future operation of this asset, thus delivering to Severn Trent a highly successful end product.
We have been working with SDS on this project for a number of years now and will continue to do so until the site is completed in six or seven years’ time. We appreciate the way in which the SDS team takes responsibility not only for ensuring the delivery of every aspect of their involvement but also for always going the extra mile to help us resolve issues on-site that sit outside of their control.
We’re working with the best and brightest innovators and technology to make the water and water recycling network smarter, by saving water, fixing problems before they happen and protecting the environment. Our key goals include zero flooding and pollution and reducing customers’ water usage to record lows of 80 litres per person per day. The ‘Smarter Drop Street’ project with SDS is one of the UK’s first comprehensive trials of retrofitted smart water tanks that will help us achieve these aims.
The Health & Safety aspect of thne Weholite system has been a huge benefit. Since the chambers were supplied pre-formed, there was no need for site gangs to provide formwork onsite in the trench. Due to their light weight, the units could be easily handled without the requirement for specialist lifting plans, again reducing time and risk within the trench. By using Weholite, the first system has been installed in less than three days.
