Dŵr Cymru Welsh Water has invested £1.5m in its Pontsticill Water Treatment Works to ensure customers supplied by the works continue to receive a first class supply of drinking water for years to come.
As part of the investment, the company has installed a new water management system into the reservoir to improve the overall quality of the water. By using large stirrers (approximately 5 metres in diameter) to circulate the water in the reservoir, the system will improve the quality of the raw water before it enters the works for full treatment.
This is the first time that Welsh Water has used a water management system of this type. After being shipped 10,333 miles to the UK from Toogoolawah in Queensland, Australia, the structure was assembled on the banks of Pontsticill reservoir. Due to its size and weight, it had to be installed using a helicopter which positioned it in the water.
Pontsticill reservoir is located in the Brecon Beacons, north of Merthyr Tydfil and was completed in 1927. It holds over 15 billion litres of water – which is equivalent to 6,000 Olympic sized swimming pools - and serves over 106,000 customers in the Merthyr area and other parts of the 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.”
Welsh Water is currently investing over £200 million to upgrade and expand water treatment works throughout Wales between 2010 and 2015.
