Yorkshire Water is upgrading its Leyburn wastewater treatment facility with a £3 million investment aimed at reducing phosphorus levels in the River Ure. The project will introduce single point ferric dosing and replace the existing sludge tank. Completion is expected in spring 2026.
The initiative is part of a regional programme targeting 85 wastewater sites with a total investment of £350 million over five years. Previous upgrades, funded with £500 million, reduced phosphorus in treated wastewater by 68%. Additional plans include improvements to 14 storm overflows on the Ure and the construction of a £6 million service reservoir in Hunton to strengthen drinking water resilience.
Phosphorus originates from household products, agriculture, and soil run-off. While small quantities support ecosystems, higher concentrations can harm water quality and aquatic life.
