Overview
On 1st April 2013, Natural Resources Wales (NRW) was formed from an amalgamation of three separate bodies in Wales namely, Environment Agency Wales (EAW), Forestry Commission Wales (FCW) and Countryside Council for Wales (CCW). The role of the Enforcement Authority for reservoirs (under the Reservoirs Act 1975) transferred as part of a previous two-year transition programme.
Once formed, NRW also acted as Undertaker for 11 registered reservoirs, predominantly flood risk management assets. During the early years NRW identified a number of potential reservoirs in their ownership or management. The in-house Supervising Engineers carried out initial investigations to determine whether they were likely to possess a raised volume capacity in excess of the new 10,000 cubic metres threshold and the likely risk classification for these structures.
Initial studies showed that NRW had 47 sites that required assessment. This soon rose to 74 as the project started. 19 sites were identified as being over the 25,000m³ threshold and duly registered with a further 12 sites registered once confirmed to be over the 10,000m³ threshold. NRW’s current reservoir stock has a variety of purposes including flood alleviation, water supply, nature reserves, historical structures and amenity.
This presentation tells the story of the challenges of forming a new organisation running in parallel with legislative changes to the Reservoir Act. From the initial investigation of numerous potential reservoirs and registration to investigative work, outcome workshops and final scheme delivery. NRW has delivered multiple construction schemes over the past 10 year to uphold reservoir safety standards which have included several discontinuance projects. Speakers will provide examples of works undertaken and the challenges ahead for NRW with regards to managing its reservoir portfolio.
