An innovative solution that could save Welsh Water two tonnes of carbon per year through transforming the management of organics during the treatment of drinking water, is one of the winners of a £40 million competition from Ofwat, the economic water regulator.

Welsh Water provides safe and reliable drinking water to over 1.4 million homes and businesses, making it the sixth largest of the 23 water companies in England and Wales. The not-for-profit water company has water treatment works where raw water is treated to make it safe enough to drink, which supplies over 800 million litres of water every day through a network covering 27,000km. By the time water reaches rivers, reservoir or aquifers, water already contains a wide variety of substances including organics which determines its quality. It absorbs dirt, dust and gases from the air, debris and bacteria from the ground, and soluble minerals from rocks.

At a water treatment works, the main objective is to remove bacteria and other unwanted substances from raw water through a drinking water treatment process. Granular activated carbon (GAC) is used during this treatment process to remove organics from the raw water– an exhaustive process that means the GAC requires thermal regeneration every three years.

The current process is carbon intensive, creating around two tonnes of carbon per year costing around £1m per year to manage. The solution proposed by Welsh Water’s innovation team and partners including Swansea University and Panton McLeod, seeks to investigate ways to regenerate GAC in situ, reducing both financial costs and carbon footprint before proposing a recommended solution that can be adopted by Welsh Water and shared with the wider industry.

Paul Gaskin, Research and Innovation Manager of Water Services at Welsh Water said:  “We are excited to be leading this project to investigate transformative ways of regenerating granular activated carbon locally. This project is an example of Welsh Water’s commitment to finding innovative solutions to environmental challenges, whilst bringing the wider industry along with us. This project ties in with our 2050 vision to become a truly world class, resilient and sustainable water service for the benefit of future generations. Along with our partners working on this project, this funding will help us tackle a key challenge faced by the entire water industry.”

Helen Campbell, Senior Director, Ofwat said: “There are big challenges in the water industry that must be solved, some are well known, and others are less so. In our fourth Water Breakthrough Challenge we called for solutions with potential to deliver wide-scale, transformational change for customers, society and the environment – and that’s exactly what today’s winners have done. From raingardens to prevent flooding to green energy from treated sewage, innovations to cut the water sector’s carbon footprint to robots that patrol the pipe network, the winners are all helping shape a more sustainable and efficient water sector.” 

Welsh Water is also partnering with others in the industry on other innovative projects including rainwater harvesting, robotic solutions for rising water mains and no-dig leak repair.

The Water Breakthrough Challenge is part of a series of competitions from Ofwat, run by Challenge Works with Arup and Isle Utilities, designed to drive innovation and collaboration in the sector to benefit individuals, society and the environment.  

It supports initiatives that help to tackle the biggest challenges facing the water sector, such as achieving net zero, protecting natural ecosystems and reducing leakage, as well as delivering value to society.

PEMBROKESHIRE-BASED Ascona Group has announced the rebranding of two of its Pembrokeshire service stations to the Valero brand. The rebranding process is set to commence next week, starting on 20 May 2024.

The two sites undergoing transformation are the Ascona – Pelcomb Service Station located at Pelcomb Cross and the Ascona – Ivy Service Station in St Clears. The company has assured that the rebranding work will be completed by the end of the week.

Ascona Group expressed their excitement about the upcoming changes and look forward to unveiling the newly branded sites to their loyal customers. In a statement, the company said, “We can’t wait to share these rebranded sites with our loyal customers. Stay tuned for more updates and thank you for your continued support.”

Customers with queries regarding the continued use of loyalty cards or fuel cards under the new Valero banner are encouraged to visit the respective stores, where options will be available to ensure a seamless transition.

The puffin, a beloved seabird and symbol of Pembrokeshire, is caught in a heated dispute over the UK’s post-Brexit fishing rules. Recently, the UK banned fishing for sandeels in the North Sea, the puffin’s main food source. But the European Union (EU) wants this ban lifted, saying it breaks the terms of the UK’s post-Brexit agreement.

Both the UK and EU need to find a solution by Thursday to avoid further problems, like potential sanctions against Britain. Conservationists argue that this is about the UK’s right to decide how to protect wildlife in its own waters.

This is the first time the EU has used its dispute resolution process in the Trade and Cooperation Agreement since Brexit. Wildlife groups across Europe strongly oppose the EU’s demand. Thirty-eight conservation organisations, including the RSPB, ClientEarth, Oceana UK, Birdlife International, and the Marine Conservation Society, support the UK’s ban.

Brexit supporters also back the ban, saying it would have been hard to achieve while the UK was in the EU due to bureaucracy and opposition from other EU countries. David Davis, a former UK Brexit minister, told the BBC that the policy serves both national and global interests, and Brexit allows the UK to make these decisions independently.

Sandeels are small, silvery fish found in large numbers in the North Sea. They are crucial for endangered seabirds, as well as seals, whales, and dolphins. Danish fishing boats are most affected by the ban, catching around 250,000 tonnes of sandeels in UK waters each year for fish oil and animal feed, especially for pigs and farmed salmon.

The RSPB has been calling for a ban on sandeel fishing for over 25 years, warning that sandeels are under pressure due to climate change. Kirsten Carter, RSPB’s head of marine policy, expressed shock at the EU’s challenge, stressing the importance of sandeels for seabird survival.

On the other side, the EU argues that the UK’s ban doesn’t consider the needs of fishing communities or marine ecosystems enough. They say the ban prevents EU fishing vessels from accessing important fishing grounds and goes against the UK’s commitments under the Trade and Cooperation Agreement.

A spokesperson for the European fishing industry defended their practices, mentioning existing quotas and protected areas. Espen Sverdrup-Jensen, president of the EU Association of Fish Producers, disputed the UK’s ban, saying there’s no scientific evidence linking it to seabird breeding success.

If the UK and EU don’t settle the issue by Thursday, it will go to an arbitration panel. If the panel rules against the UK and the government refuses to comply, Brussels could respond with tariffs or other actions
