Black & Veatch Ensures Long-Term Security and Quality of Water in North East Wales

Black & Veatch Ensures Long-Term Security and Quality of Water in North East Wales

Project Name
Llwyn Onn Water Treatment Works Rebuilding
Wrexham, UK
Dee Valley Water

What Black & Veatch does isn’t always visible to the people and communities where we work. However, to families and businesses in and around Wrexham, UK, clean, clear drinking water is readily apparent today. Dee Valley Water’s Llwyn Onn Water Treatment Works provides the people of Wrexham colourless, odourless drinking water free of manganese, a naturally occurring mineral that is prevalent in the rocks and soil in Wales.

Llwyn Onn Water Treatment Works had reliably supplied raw water quality since World War II, when it was built to supply water to a munitions factory; however, the aging structure and prevalence of manganese necessitated replacement of the treatment system. Dee Valley Water called on Black & Veatch to replace the aging works while keeping the existing works operating.

Modular Approach

Black & Veatch delivered an integrated design-build solution that accommodated Dee Valley Water’s need for optimised structures within a severely constrained site, without affecting the integrity and operation of the existing plant during construction. Through a modular approach, the new structures were designed and constructed off-site to accommodate the challenging constraints of the working environment.

The upgrade, including the introduction of a technologically innovative secondary water treatment process to better manage the levels of manganese in the water supply, improved Llwyn Onn’s treatment capabilities.

Black & Veatch has partnered with Dee Valley Water for more than 20 years. The project has been Dee Valley Water’s largest project ever and will ensure the supply of quality water to the 98,000 domestic and commercial customers in and around Wrexham.

Black & Veatch’s use of 3-D building design allowed Dee Valley Water to “walk through” the building even before foundations were constructed.
