Starting with a great idea, our GEOlight® geo-cellular stormwater attenuation and infiltration system, SDS has grown in size over its 20 year history to become the UK’s leader in sustainable drainage systems. More recently, to meet the increasing importance of water quality, we have extended our portfolio to include new water treatment systems. We are committed to the continuing development of innovative new engineering solutions to meet forthcoming market requirements and to meet the demands of our growing base of customers. In every project we handle we are fully aware of the commercial constraints of our clients and strive to deliver best value. Often we may advise prospective customers on ways in which they can reduce cost or add value without impinging on the performance and reliability of the desired solution; indeed this principle has both attracted new customers to us and contributed to the extremely high level of customer loyalty we enjoy. By taking responsibility for each element of the project, from specification, design and manufacture to delivery, installation and maintenance, we can ensure that our systems will always operate to their maximum efficiency potential.
