NOVEMBER "Changing is about innovating, it's about listening, it's about doing things differently – because how can you cope with a changing world, how can I be here for you as my customer if I am not going to change in response to a changing environment and your changing expectations?" Thames CEO Steve Robertson tells Utility Week the company is ready to evolve £21M Northumbrian Water is spending £21 million on two new water treatment works in north Northumberland to help improve tap water quality for more than 25,000 people 50% Changing the material used in pavements to travertine – a form of limestone – could reduce flooding by 50 per cent and purify stormwater at the same time, according to researchers from Xi'an Jiaotong- Liverpool University "Pillow packer lining is ideal for fast, safe, and sustainable repair of large-diameter pipes and culverts with minimal disruption to assets, services and the wider environment" Lanes Group plc's Mark Scott on the use of the technology to rehabilitate a pipe that that will play a crucial role in creating Europe's largest man-made nature reserve "Our thorough analysis of the raw data from five DERAGGER trial sites clearly demonstrates the impact this innovation can have in the wastewater sector" WRc head of technology Dr Leo Carswell on DERAGGER, which was found to cut energy consumption by up to 80 per cent, significantly reduce maintenance requirements and help extend asset life Y orkshire Water is to in- vest £30 million in its wastewater treatment works in Saltend, Hull, to im- prove the site's operation. MMB (Mott MacDonald Bentley) will carry out the work, which will begin in December and is due to be completed in late autumn 2020. Existing anaerobic digestion (AD) at the site will be extended and upgraded, helping to produce more biogas, which is used to fuel combined heat and power (CHP) engines, heating water and generating electricity. This electricity will be used to power the site and any surplus electricity will be transferred to the electricity grid. Yorkshire Water is also looking at alternative uses of the biogas, such as injecting in to the gas grid to provide renewable energy to homes and businesses. The site will also have a new inlet works, which will make the site more resilient by giving the firm greater ability to remove unwanted items from the incoming wastewater. Yorkshire Water senior project manager Mike Smith said: "We are delighted to announce this investment, which will make a huge improvement to the performance of the site. "This investment shows our commitment to invest in renewable energy and benefit the environment as we look at ways of becoming more efficient and self-sufficient and help keep customers' bills low." IN A NUTSHELL 2 WET NEWS DECEMBER 2018 | wwtonline.co.uk £219M Welsh Water announced record capital investment in the six-month period from April to September, and expects that to rise to £460 million in the year to March 2019 S ustainable drainage sys- tems (SuDS) will become mandatory for new prop- erty developments in Wales from next year, following regu- lations introduced by the Welsh Government. SuDS make use of landscape and natural vegetation to control the flow of surface water and reduce the risk of flooding. Designs can include ponds, permeable paving and swales, which slow down the discharge of surface water more than conventional piped drainage. Surface runoff water can also be a major source of pollution, both directly and from overwhelmed sewers discharging into rivers. SuDS are designed to improve water quality while being more resilient and longer lasting than conventional drainage. As part of the regulations, SuDS Approving Bodies (SABs) will be set up within every local authority to approve drainage plans. The SAB or local planning authorities will have powers to issue enforcement notices to a developer who breaches the requirements. Developers will have a right of appeal to Welsh Government against the decision of a SAB. Environment Minister Hannah Blythyn said: "Surface • SuDS Approving Bodies and local planning authorities will be given powers to issue enforcement notices to any developers that breach the new Welsh Government requirements • Mott MacDonald Bentley project will help the water company process more sludge and use it to generate energy Wales makes SuDS compulsory in new developments from next year Yorkshire Water announces Saltend WWTW investment water flooding can have a devastating impact on communities and our economy. The recent flooding we've seen in parts of Wales have underlined the need to adapt to the challenges of climate change. "Around 163,000 properties in Wales are at risk of surface water flooding. Employing sustainable drainage systems are estimated to reduce flood damage by up to 30 per cent. "Until now, the uptake of SuDS has been low. These regulations will help reduce flood risk and improve water quality, while also introducing homes for wildlife within new housing developments."
