The company currently provides commercial and project management across Welsh Water's capital programme, and the extended contract will see it aim to streamline core service delivery. • Energy and environ- mental consultancy Ricardo-AEA has clinched two new flagship UK contracts. The first project is a three-year deal to manage the UK Water Technology List fopr Defra and HM Revenue & Customs. The second contract is a two-year project for industry research body UKWIR to explore attitudes and perceived barriers to the use of biodegradable products containing sewage sludge. Scottish Water earmarks £3.5B for capital delivery • Improving drinking water quality and tackling wastewater discharges top Scottish Water's agenda for 2015-21 S cottish Water plans a £3.5B capital investment programme for the six years to 2021, as it aims to improve drinking water quality as well as tackle wastewater discharges. The overall cost of deliver- ing the plan is expected to be £8B, which will be met through £7B of customer charges and net new government borrowing of £720M. The company is proposing to invest £340M on improving drinking water quality; almost £115M on its sewer infrastructure; and more than £174M on tackling wastewater discharges, including reducing the impact of more than 60 storm overflow discharges to the River Clyde Scottish Water has also earmarked almost £66M to lessen the impact of discharges from two Glasgow wastewater treatment works. The company said its asset maintenance costs are rising and are forecast to do so over the next ten years, and the investment will sustain the significant improvements it has made to customer service and statutory compliance over the past 12 years. Its assessment indicates capital maintenance demand will increase from £272M a year in 2012/13 to £285M annually in 2020/21, an average of £280M a year over the2015 to 2021 period. Scottish Water's plan to improve drinking water quality entails adopting a mix of innovative and proven solutions. Operational solu- tions include mains flushing to remove iron and manganese deposits; and sustainable land management activities. It is also planning reservoir mixing to control manganese levels entering treatment works. Also, £177.9M of the £340.1M earmarked for drinking water quality improvements will be used to address statutory requirements including replac- ing 6,500 lead communication pipes; rehabilitating 397km of water mains and cleaning; and 26 water supplies that do not comply with current standards. Almost £115M will be invested to improve Scottish Water's sewer network to remove all customers from the internal sewer flooding register as quickly as possible. The company said it is con- tinually assessing and deploying new techniques to more accurately locate poten- tial leaks in its water supply network, allowing early inter- vention before supplies are interrupted and speeding up the repair process. It uses non-destructive testing devices in live water mains to allow the integrity of the pipe walls to be inspected and pipes repaired before services are interrupted or leaks begin. Commenting on its plans for 2015-21, the company said: This plan builds on the transforma- tion in service levels and effi- ciency that we are proud to have delivered over the past 12 years for our customers. We are now delivering services that are comparable with the best companies in the UK at an average cost to household customers of over £50 a year below the average in England and Wales. "We are now delivering services that are comparable with the best companies in the UK" Scottish Water • The third and final part of Thames Water's 'super sewer' has been put out to tender, with successful bidders to be announced in 2015 Tideway Tunnel final section out to tender T he tender for the third and final section of the Thames Tideway Tunnel has been released by Thames Water, with the successful bidders expected to be announced in May 2015. Thames Water has sent out the invitation to tender (ITT) for the Central package of work to construct the 25km tunnel in London. The project has been split geographically into three main construction works con- tracts, with the ITT for West sent out in December 2013 and East in January 2014. The three main works pack- ages are worth up to £2.3B – West (£300M-£500M), Central (£600M-£950M) and East (£500M-£800M). The Development Consent Application for Thames Tideway Tunnel is currently being consid- ered by the Planning Inspectorate and, subject to consent being granted, construction on the pro- ject is due to start in 2016. It will involve 24 construction sites across London. Mike Gerrard, Thames Tide- way Tunnel managing director, said: "We are making excellent progress with the tender process and we are confident that we will receive competitive bids that will result in the best value for our customers. "We are building for 22nd Century London to create a cleaner, healthier River Thames. The Thames Tideway Tunnel is needed to tackle the tens of mil- lions of tonnes of raw sewage which discharge into the tidal River Thames every year. The river needs cleaning up and it needs to be cleaned up now." Alongside the environmental improvements to the tidal River Thames, the tunnel will create more than 9,000 jobs. Already, around 500 people are working on the pro- ject. The project will be financed and delivered by an independ- ent Infrastructure Provider (IP), with its own licence from Ofwat. Procurement of the new IP is expected to begin next month.
