AquaTreat Surface Water Treatment (SWT) Separator Range FAQs

What does SuDs mean?

SuDs stands for Sustainable Drainage Systems. They are systems designed to be environmentally beneficial, to ensure minimal or no long-term detrimental damage to the surrounding environment. It is a term used to describe control strategies or products that allow the efficient and sustainable drainage of surface water, to help minimise pollution and manage the impact on water quality in local water bodies.

 SuDs help to manage surface rainfall run-off by controlling the rate and volume of the runoff. This helps to relieve pressure on sewerage systems, imitating natural drainage as closely as possible. SuDs can help local authorities, planners, architects, and developers deliver greener infrastructure.

What are the advantages of a SuDS?

Sustainable drainage systems (SuDS) present an opportunity to add value to a project, while meeting  local planning requirements around increasing sustainability and managing flood risk. They can help save you time and money but that’s not all.

SuDS reduce the impact of urbanisation on flooding, by managing runoff and flow rates from hard surfaces. They provide opportunities for using runoff where it falls, such as rainwater harvesting, that in turn helps to reduce both the flow into sewers and our dependency on mains water. Some SUDs can help to reduce pollution, protecting the quality of downstream water bodies such as streams, rivers, lakes, bathing, or shellfish waters. They preserve the natural flow regimes in watercourses and, by being sympathetic to the environment and the needs of the local community, create better places to live, work and visit. Urban watercourses can provide an attractive habitat for wildlife, as well as providing opportunities for evapotranspiration from vegetation and surface water.

What types of SuDs are available?

Bypass and full retention separators

 Sometimes known as petrol interceptors, bypass and full retention separators are designed to manage runoffs and spills, whether that’s from large amounts of rainfall or the accidental spillage of oil or fuel. These separators will protect your local environment from pollutants and help reduce the risk of large fines from the Environment Agency. Full retention separators are used when there’s a medium to high risk of contamination caused by spillage or flooding, for example in large car parks, industrial workshops, and recycling centres. Bypass separators are used when the area has a low risk of contamination, such as roadways or commercial areas that would only get light contamination. It can cope with water flow generated by rainfall up to 6.5mm per hour.

Domestic rainwater harvesting

Rainwater harvesting is an eco-friendly way of reducing water usage in your home. There are two types of systems available – direct and in-direct. In a direct system, harvested water is pumped directly to the appliances, whereas in an in-direct system, the harvested rainwater gets stored in a holding tank and gravity feeds the appliances. The harvested water can be used for a variety of appliances, including toilets, showers, baths, sinks and washing machines.

Surface water treatment separators

Surface water treatment separators (SWT) reduce pollution in line with SuDs Mitigation Indices by removing metals, hydrocarbons, and suspended solids from surface water. Our SWTs are lightweight and easy to install and can be maintained and serviced from ground level.

Vertical and horizontal flow control solutions

 Designed to control the flow of water into local watercourses, flow control solutions reduce the risk of flooding on natural habitats and prevent bank erosion.

Vertical and horizontal pump stations

 Used in housing estates, hospitals, and commercial sites, sewage pumping stations transport sewage or wastewater when gravity cannot naturally carry it, such as where a sewer line may travel up an incline or over a ridge. They work by collecting wastewater and storing it in a chamber. When the chamber is full, a high-pressure integral pump lifts the sewage through a discharge system before pumping it into a sewage treatment works.
