Providing water and wastewater services uses energy, chemicals, materials and natural resources.
Using these carefully helps reduce environmental impact, manage costs and support a more circular economy.
Our approach is to reduce what we use, recover value where we can and avoid waste wherever possible.
Reusing materials already in our processes
We are finding practical uses for materials produced through our day-to-day operations, helping reduce waste and avoid unnecessary disposal.
Treated biosolids from our wastewater processes are recycled to agricultural land where appropriate, supporting soil health and reducing reliance on manufactured fertilisers. Over the last three years, we have applied an average of 25,641 tonnes of biosolids to land annually.
We also repurpose around 36,000 tonnes of grit from wastewater treatment each year in land reclamation projects at Seal Sands, delivering annual cost savings of approximately £1.8 million.
