Dwr Cymru Welsh Water, Wales, 2000 - 2008 (ongoing)
Rehabilitation and ongoing maintenance of Hydrometric network for monitoring water abstraction and compensation flow gauges across the whole of Wales.

Hydro-Logic has been commissioned by Dwr Cymru Welsh Water to install, operate and maintain a large network of telemetry enabled reservoir level and compensation flow gauges across the whole of Wales. The initial contract covered five years and following an EU OJEC re-tendering process, a new contract for six years was awarded in April 2006.

Dwr Cymru Welsh Water
Design, supply and installation of a compensation flow gauge at Cwmystradllyn Reservoir, North Wales. 2006

Hydro-Logic have been engaged by Dwr Cymru/Welsh Water since 2000 to operate, maintain and improve their hydrometric network. One of the projects involved the feasibility, design and installation of a new ultrasonic transit-time flow gauge on the discharge compensation flow channel from Cwmystradllyn Reservoir in North Wales.

Scottish Water, 2007 ongoing
Improving reservoir yield assessments and compensation flow monitoring

Scottish Water commissioned HL in 2007 to deliver two separate flow monitoring contracts to help improve the water companies understanding of the yield and low flow conditions at several water supply catchments across Scotland.

EA Southern Region (via Halcrow)
Design and supply of ultrasonic transit-time flow meter at a complex site on the Kent Ditch

HL was commissioned by the EA Southern Region, as sub-consultants to Halcrow Consulting Engineers, to undertake the feasibility and hydrometric design of 6 sites on streams feeding the Romney Marsh. On one of the streams, the Kent Ditch, it was necessary to design a two section/stage gauging station for which a Sarasota 2000 ultrasonic transit-time meter was installed.

Wessex Water,
Design, supply and installation of low-flow environmental impacts monitoring system on the River Yeo in Somerset, 2005-2008

Wessex Water contracted HL to install a new flow-gauge to provide flow data on the environmental impact of abstraction upstream and downstream of a riverside borehole for public-supply. Due to the channel and hydraulic conditions at the site on the River Yeo in Somerset, HL selected a horizontal ADCP Channelmaster device from Teledyne RDi for providing accurate velocity profiles at one elevation at a convenient section under a footbridge, so that a velocity index rating could be established.
