Dŵr Cymru Welsh Water spent £483 million to maintain and improve its assets in the last 12 months to improve services and to protect the environment, according to the company’s financial results for 2023/24.
The investment includes seven investment schemes totalling £53 million to help improve the quality of the River Wye as well as good progress being made on the River Teifi and other Special Areas of Conservation (SAC) Rivers.
Welsh Water said its financial results also restate the company’s sound and stable financial position, with the highest credit ratings in the sector and low levels of gearing compared to the rest of the sector.
Last year, the not-for-profit company published its Manifesto for Rivers in Wales outlining how it would be investing to improve river water quality in its operating area. The company will spend £840 million in the five years to 2025 (AMP7) and a further £2 billion proposed between 2025 and 2030 (AMP8) to improve its wastewater network and protect the environment, subject to approval from Ofwat.
With growing public interest in the quality of rivers, the Manifesto responded directly to the then First Minister of Wales’s call for every sector to reduce their impact on Welsh rivers. Additional investment was committed specifically by Welsh Water to reduce phosphorous in the five failing SAC rivers – the Wye, Usk, Teifi, Cleddau and Dee rivers. It says its not-for-shareholder business model has allowed it to accelerate this programme by an extra £100 million.
In addition, Welsh Water has confirmed it has agreed 145 new environmental permits with Natural Resources Wales to reduce phosphorous at its treatment works and other assets to improve river water quality.
In total, Welsh Water has completed 50 major capital schemes – those of more than £1 million – in the year across its network, both waste and clean water, to improve its service to customers and lessen the impact on the environment.
Chair of Glas Cymru, Alastair Lyons, said:
“Our strong financial position has allowed us to maintain our focus on improving our services to our customers and communities and delivering on our promises to reduce our impact on river water quality. Our plans have to find the right balance of being financeable, deliverable and affordable for our customers without storing up problems for future generations. Whilst there’s still much more to do, we are making good progress against the commitments we’ve made.”
Looking to 2024/25, the company will continue to deliver on the promises set out in its Manifesto. In May Welsh Water took a further step towards starting work on its brand new £20 million wastewater treatment works for Cardigan by submitting its plans for planning approval. This significant scheme, which is set to start in April 2025, will provide increased capacity at the works and materially reduce the number of discharges from the site, in turn benefiting the River Teifi. The company has also confirmed investment in its wider network across the Teifi catchment which will include spending over £5 million on three treatment works by the end of March 2025.
As well as investing in conventional engineering solutions, the company is also progressing with delivering green infrastructure to improve river water quality. At New Inn near Pontypool, a £13 million scheme has just got underway which is set to become the first of its kind in the UK. The project will create a 1.8-hectare wetland for the local community that will also serve as a green filtering system for stormwater discharged from the nearby storm overflow during heavy rain. Once completed, the stormwater will pass through the wetland before it is released into the Afon Lwyd which will help improve the quality of the river and also the main water body it flows into, the River Usk.
Welsh Water Chief Executive, Peter Perry, said:
“We’re delighted to be creating this innovative wetland that will mitigate the effects of wastewater from a storm overflow by naturally removing the phosphorus. In line with Welsh Government policy, we are prioritising investment in the storm overflows that cause environmental harm rather than those which spill the most. Our investment in our wastewater system – which will total £1.4 billion in the decade to 2025 – has delivered real improvements and helped ensure Wales has over a quarter of the UK’s Blue Flag beaches while only having 15% of the coastline and that 44% of our rivers and waterbodies meet good ecological status. We have a lot more work to do and we look forward to Ofwat’s Draft Determination on our Business Plan for 2025-30 expected in July which could bring record levels of investment to tackle the issues our customers are concerned about.”
