4 WET NEWS FEBRUARY 2016 News+ CONTRACT WINS Good monthT- Bad month Veolia has picked up one of the longest water industry deals – 20 years, and it's with Irish Water. Lanes' expansion continues, this time with the takeover of Irish group Arlo. For Thames Water and Yorkshire Water, both of which incurred fines in pollution incidents. Thames received a record-breaking £1M fine for polluting the Grand Union Canal in Hert- fordshire, and Yorkshire Water was hit with a £600K fine for a sewage pipe burst that killed fish in a Wakefield lake. New supply source needed to meet South-east demand • ICE report reveals three options, including wastewater re-use, that are under consideration at Thames Water. A new source of water supply is needed in the South-east to combat demand from a growing population and more adverse weather conditions, according to the Institution of Civil Engineers' (ICE) London and South East regions. A report by ICE's London and South East Expert Water Panel examines the three options being investigated by Thames Water as part of its Water Resource Management Plan (WRMP). These are: a reservoir at Abingdon; the transfer of raw water from the River Severn; and a wastewater reuse site at Deephams or Beckton Sewage Treatment Works. The panel's initial analysis of the options has shown that an "Abingdon Reservoir would ensure a long-term water supply" and is inevitable at some point. However, the reservoir is not deliverable before 2027/8, when a gap in supply is predicted. A preferable medium-term solution, said the panel, would be wastewater re-use at Beckton. However, the energy intensity and cost of the scheme means it should be used as a last resort, rather than regularly, without energy efficient technologies being developed. The panel also recognised that "public acceptability will be a big hurdle" to implementing wastewater reuse. As a result, it has urged Thames Water to consider other In AMP6, Thames Water is committed to investigating various options as part of WRMP14 A level 4 drought order requiring rota cuts would cost between £236M and £330M a day Water supply demand is forecast to exceed by 10% in 2025 A consistent data period exceeding 90 years should be developed by Ofwat for water companies • MEICA contractor Nomenca "is proud" to have secured a framework agreement with Wessex Water Services to deliver a range of projects during AMP6. Nomenca managing director Andy Langman said it was a great opportunity to continue investing in growing teams in the South-west. • Avtar Jirh, managing director of Doosan Enpure, is "delighted" at the company being appointed principal contractor for the £22M upgrade of Sutton and East Surrey Water's Woodmansterne WTW at Chipstead, Surrey. • Mott MacDonald is "pleased" to be carrying out a water resilience project on behalf of Water UK. The project, called Water Resources – Planning for the Long-term, aims to provide a planning framework that will shape water resourcing strategy in the UK for the next 50 years at least. • United Utilities' Business Solutions has been appointed to build an anaerobic digestion plant at The Glenmorangie Company's Tain distillery. options and to continue its programme of water efficiency savings. Dave Wardle, chair of the London and South East Expert Water Panel, said: "Due to climate change and an increasing population, it is essential that we prepare for higher water demand over the next two decades. Thames Water is considering three options to increase water supply, each with different benefits and costs. "The panel's analysis suggests that, at some time in the future, we will require a large scale water resource, such as the Abingdon Reservoir. The other solutions screened by Thames Water, the wastewater treatment site and the raw water transfer, can be provided in a shorter timeframe, but require further evaluation. Thames Water must continue with this open and transparent process to determine what solution is best." Over the next 35 years, London's population growth is expected to rise by 37% to more than 11 million people and demand for water is expected to exceed supply by 10% in 2025 and by 21% in 2040. "With the demand to live and work in the South-east continuing to rise, these predictions looking increasingly accurate," said the report. It added that a level 3 Drought Order would result in a £4.3M-£9.5M a day cost for London. www.teekaycouplings.com tel: +44 (0)1494 679500 • More than 200,000 people and businesses set to benefit from the improved water supply network. S cottish Water is investing £120M to improve the water supply network by installing 30 miles of new water mains to connect the system in Ayrshire with the Greater Glasgow area's network. More than 200,000 people and businesses in much of Ayrshire and parts of East Renfrewshire will benefit from the investment. Customers across a large part of Ayrshire currently receive water from the Bradan Water Treatment Works, south of Straiton in South Ayrshire. The water is supplied via a 34-mile- long trunk water main installed from the Bradan WTW to the north of Irvine. The construction of 30 miles of new strategic water mains will connect the Bradan water supply network to the network served by the Milngavie and Balmore water treatment works. The investment will enable Scottish Water to transfer water from Glasgow to Ayrshire, and vice-versa, if required. This will create a more robust and connected supply zone that will Wastewater re-use at Beckton STW would be a medium-term solution Scottish Water plans multimillion-pound investment on new water mains benefit customers in areas such as Ayr, Prestwick, Kilmarnock, Troon, Irvine, Fenwick, Galston, Stewarton, and Hurlford. Another key part of the investment will deliver improved water quality to about 56,000 people as the existing water supply from three small water treatment works in East Ayrshire and East Renfrewshire is replaced with water supplied from the Glasgow network. Douglas Millican, Scottish Water's chief executive, said: "This major strategic investment scheme, which will deliver a more resilient water supply network for Ayrshire, is the first stage in our investment to improve connections between water supply networks across Scotland. We have invested significantly in improvements to water quality in parts of Ayrshire in recent years and now, as proposed in our strategic projections, we will improve much of the area's water supply resilience by creating a new link between the supply systems."
