West Norfolk innovation keeps Welsh water clean
09:38 03 September 2014
Customers in Wales will enjoy better water thanks to new technology to keep reservoirs clear, imported from more than 10,000 miles away.
King’s Lynn-based Gurney Environmental fitted giant aerators with 5m blades to Welsh Water’s Pontsticill Reservoir, in the Brecon Beacons.
They were part of a £1.5m investment in the reservoir and its treatment works by the customer-owned utility.
The technology circulates water around the reservoir, improving the quality of the raw water which has fallen on the nearby hills before it enters the works for full treatment.
The water management system, constructed by WEARS Australia, was shipped 10,333 miles to the UK from Toogoolawah in Queensland, Australia, before being assembled on the banks of the lake.
Due to its size and weight, it had to be installed into the reservoir using a helicopter which positioned it in the water.
Pontsticill Reservoir, north of Merthyr Tydfil, was built in 1927 and holds more than 15bn litres of water – the equivalent to 6,000 Olympic swimming pools.
It supplies more than 106,000 customers in the Merthyr area and South Wales valleys.
Welsh Water’s Capital Delivery Manager for South East Wales, Roy Samuel said: “We are very pleased to be using this innovative management system in the reservoir at Pontsticill. This investment will improve the water quality for customers in the area and ensure they continue to receive a top quality supply of drinking water long into the future.”
