6 | INNOVATION 2018 A VK UK Limited was awarded a contract for the provision of four DN800 Series 55 Resilient Seated Gate Valves along with nine DN900 Metal Seated Gate Valves by the Caledonia Water Alliance (Morrison Utility Services Limited and AECOM) on the Dalmacoulter Resilience Scheme for ulti- mate client Scottish Water. The valves are the first of their kind ever to have been supplied on a UK scheme hav- ing only been available and supplied up to DN600 before this order. Discussions began early 2016, and the valves were delivered to site in Octo- ber 2016. The Caledonia Water Alliance, formed by Morrison Utility Services Limited and AECOM, was named in 2014 as the preferred bidder to sup- port the delivery of Scottish Water's water infrastructure element of its capital invest- ment programme. The contract included programme management, together with the design and construction of works associ- ated with the water network across the whole of Scotland along with new assets, renew- als, modifications, mainte- nance and refurbishment of water networks and pumping stations. The Dalmacoulter Resilience Scheme is for the construction of a 1000mm diameter HPPE pipeline ap- proximately 6km in length running from Cumbernauld to Airdrie. The pipeline is being con- structed in duplication to the existing pre-stressed concrete pumping main to ensure the resilience of supply to 185,000 people. The pipeline is being con- structed in duplication to the existing pre-stressed concrete pumping main to ensure the resilience of supply to 185,000 people. It was established that on two of the DN800 Gate Valves, there would not be enough headroom for the valves to sit in the vertical position. One of the key advantages of the AVK Series 55 Resilient Seated Gate Valve is that you can install them vertically or horizon- tally as standard without any modifications required to the valve. This allowed us to eas- ily overcome this challenge whilst giving the customer the flexibility to install in either position."
