In the fullness of time, the works had become unable to meet increased population demands and was failing to comply with ever-stricter river quality discharge requirements.
Due to the location of Lydbrook WwTW within the Wye Valley area of outstanding natural beauty - adjacent to Offa's Dyke (scheduled ancient monument and national trail) - and with the River Wye being a Site of Special Scientific Interest (SSSI), Black and Veatch worked very closely with the Environment Agency (EA) and local archaeological services to ensure that a large number of sensitive environmental requirements were adhered to.
Improvements made by Black and Veatch in its ongoing role as a partner in the Dwr Cymru Welsh Water Capital Alliance, included the installation of a new inlet screen, upgrading of the primary settlement tanks, provision of two new humus settlement tanks and automated de-sludging facilities.
In addition, a new storm tank was installed, as well as a storm return system, increased capacity in the site electrical supply, new MCC and process instrumentation including flow measurement of the final effluent, which is now well within the EA discharge consent.
