Anglian Water has unveiled plans for a "hugely ambitious" wetlands programme, comprising 26 sites across its region that will be used to naturally remove nitrates and phosphates from wastewater without the need for chemical dosing. The plans were announced as the company reported its largest ever single-year capex programme in its financial results for 2021/22, which also included a net penalty of £8 million on outcome delivery incentives after it missed pollution and flooding targets.
