Hydro-BPT Project Team visit Cefni Reservoir and Water Treatment Works
As part of the quarterly Hydro-BPT project team meeting which took place in December 2012, a visit to Llyn Cefni Reservoir and Treatment works was organised. The site is located outside the town of Llangefni in Anglesey, Wales. The treatment works is one of the many sites in Wales run by Dŵr Cymru Welsh Water.

Cefni Reservoir and Water Treatment Works which treats and supplies 6,900 m3/day (80 l/s) using approximately 7250 kW/day. As part of the tour of the water treatment works, the team got to see the current pumping facilities (as shown in the next figure). Six Large pumps are located on site and ensure the continuous supply of water to the local communities on Anglesey.

A pressure reducing valve (PRV) is also located on the site, but is currently not in use. The purpose of the PRV is for water supply from other parts of Wales due to any failure on site to supply water to Anglesey. This PRV is one of over 170 PRVs located in Wales and the majority of these PRVs are currently active. The Hydro-BPT project aims to assess the feasibility of replacing these PRVs with micro-hydro turbines, which could generate power and could feed into the local grid.
