CW take the high road to Rannoch hydro scheme


CW Engineering have completed a purpose built weed screen cleaning system at the new hydro scheme on the Rannoch River in Morvern, part of Scotland’s North West Highlands, a scheme that will power 750 homes when it is fully operational.

When the scheme was approved in 2009, Energy Minister Jim Mather said "Renewable energy developments will help Scotland's economic recovery. Working in harmony with the environment, this scheme will generate clean, green energy, reduce emissions and create 12 new construction jobs - a model of the low carbon opportunities that exist the length and breadth of Scotland. "We will continue to support sustainable hydro power developments to tackle climate change and help increase sustainable economic growth."

Scottish Government targets are to meet 50 per cent of electricity demand from renewables by 2020, and an interim target of 31 per cent by 2011.

Main contractors Donald MacDonald Contractors Ltd and engineering consultants Hydroplan UK are working on

behalf of Ardtornish Estate Company Ltd on the construction of the Rannoch River hydro electric station with a generating capacity of up to 1.5 megawatts. They approached CW Engineering to design, manufacture and install a weed screen cleaner to keep the turbine intake screen clear of trash. This has been installed directly above the intake screen on the dam upper platform.

The Weed Screen Cleaner is fully programmable and has drawn compliments from the Ardtornish Estate Manager regarding its robust construction which will

“withstand the local weather conditions”.

CW Engineering will be exhibiting at the Energy Now Expo Scotland 2012 exhibition in September.

CW Engineering is probably the industry’s leading designer and manufacturer of weed screen cleaners. In recent years their innovative designs have solved numerous site challenges. Their services encompass design, engineering, controls, installation and maintenance. They also specialise in the refurbishment of weed screen cleaners and lock gates/ sluices.

Fish friendly pumps fulfil dual purpose for kempsey


The village of Kempsey, just South of Worcester, has hit the headlines on many an occasion over the years as a consequence of its extreme misfortune to be the casualty of repeated flooding.

The Environment Agency has just completed a Flood Risk Management Scheme at a cost of £1.7M to reduce the risk of flooding to over 150 properties in the village that have been affected by floods 23 times in the past 30 years.

A 180m long earth retention embankment has been constructed downstream of the village to stop flood water from the River Severn. A large penstock will allow the Hatfield Brook to flow freely into the river during periods of low flood risk. During high risk periods the penstock will close to prevent flows backing up the Hatfield Brook into the village. A new pumping station has been constructed by Galliford Try and Bedford Pumps was awarded the subcontract to supply the pumps which will discharge water from the brook to the other side of the embankment, thus reducing the risk of flooding to the village of Kempsey.

The pumps however, manufactured by Bedford Pumps Ltd, the UK’s leading manufacturers of large submersible and conventional pumps to
