Water quality improvements in South Yorkshire have been strengthened following completion of an £8.9 million wastewater treatment upgrade by Yorkshire Water at the Ingbirchworth and Hoylandswaine treatment works.
The investment focuses on reducing phosphorus concentrations in treated wastewater discharged into Banks Bottom Dike, a tributary that connects to the River Don. The project is expected to improve water quality along approximately 3.7 kilometres of the affected watercourse.
Phosphorus is commonly found in domestic wastewater through products such as detergents and shampoos, as well as from agricultural runoff. While phosphorus plays an important role in aquatic ecosystems, excessive levels can contribute to nutrient pollution and ecological imbalance in rivers and streams.
Joe Summers, project manager at Yorkshire Water, said the improvements are designed to help protect local waterways.
“It’s important that we keep looking at ways in which we can better take care of our environment, and we know that it matters to our customers too. Reducing the phosphorus levels in our treated wastewater is one way in which we can improve the health of our rivers.”
South Yorkshire wastewater upgrade targets phosphorus reduction
The South Yorkshire wastewater upgrade forms part of a wider programme of environmental investment across the region aimed at reducing nutrient pollution and improving river ecosystems.
Phosphorus is present in many household products that enter sewer systems through washing machines, showers and kitchen waste streams. It can also reach waterways through fertiliser runoff from agricultural land and natural soil erosion.
In controlled quantities phosphorus supports aquatic life. However, excessive concentrations can stimulate algal growth, which reduces oxygen levels in water and can harm fish, invertebrates and other organisms.
The upgraded treatment processes at the Ingbirchworth and Hoylandswaine facilities are designed to remove greater amounts of phosphorus before treated effluent is released into surrounding waterways.
According to Yorkshire Water, early monitoring indicates that final effluent phosphorus levels from both treatment works are now well below limits set by the UK Environment Agency.
WINEP environmental investment programme
The projects contribute to a broader environmental improvement programme being delivered under the UK’s Water Industry National Environment Programme (WINEP), which sets regulatory requirements for water companies to protect rivers, habitats and water quality.
Yorkshire Water has invested approximately £500 million in phosphorus removal schemes across the region under the current WINEP cycle. The utility plans to invest a further £2 billion in environmental improvements focused on wastewater treatment and storm overflow management.
These investments form part of Yorkshire Water’s wider £8.3 billion infrastructure and environmental programme scheduled over the next five years.
