Welsh Water has started work on a £31 million pound investment scheme which will ensure nearly 100,000 customers in Llandudno, Colwyn Bay, Conwy and surrounding areas continue to receive a top quality drinking water supply.
Work to expand the water treatment works at Bryn Cowlyd in Dolgarrog started this week and is expected to be completed in December 2017. There will be no impact on water supply to local customers during the work.
The scheme is the largest investment on a treatment works by Welsh Water in the current AMP6 investment programme.
The current treatment works at Bryn Cowlyd was built in 1998 and draws water from Llyn Cowlyd in the Carneddau Mountains. It has supplied 44,000 homes and businesses in the Conwy Valley for nearly 20 years.
The utility said the £31 million investment to expand the treatment works will ensure the work continues to supply high quality drinking water to its customers as well as meet water quality standards as set out by the Drinking Water Inspectorate.
Welsh Water’s Project Manager at Bryn Cowlyd, Ron Durrans said:
“Our £31 million investment is essential to ensure we continue to provide customers in the area with a first class drinking water supply. As a not for profit company we continue to invest in our assets to strengthen our resilience and continue to improve the service to our customers.”
The expansion to Bryn Cowlyd will be built on the current site next to the existing treatment works and although will be mostly concealed from the road by trees, the buildings will be sympathetic to their surroundings and similar to those already on site.
