United Utilities has created new woodlands and restored peatlands across more than 2,200 football pitches’ worth of land at its North West water catchment sites, signalling a major landscape-scale intervention in source protection. Large-scale peatland preservation and tree planting in upland catchments can materially reduce peak runoff, improve raw water quality by cutting colour and turbidity, and stabilise slopes, with long-term implications for reservoir yield, treatment costs and geotechnical performance of adjacent infrastructure.

United Utilities has announced a £30M programme to retrofit sustainable drainage across Liverpool, aiming to make the city “spongier” by intercepting and attenuating rainfall before it reaches combined sewers. Measures are expected to include permeable paving, rain gardens and other SuDS features on highways and public realm to cut surface runoff volumes and peak flows during intense storms. For civil and drainage engineers, the scheme signals more retrofit SuDS design in dense urban streetscapes, with a premium on hydraulic modelling, utility coordination and constructability in constrained corridors.

Ofwat has accepted a £44.7M enforcement package from Dŵr Cymru Welsh Water to remediate wastewater network failures and cut sewage spills across Wales. The measures will target storm overflows and underperforming treatment works, with investment directed to upgrading sewer infrastructure, increasing storage capacity and improving process control at key wastewater treatment plants. For civil and environmental engineers, the programme signals near-term demand for hydraulic modelling, network rehabilitation, and construction of additional attenuation and treatment assets under tighter regulatory scrutiny.
