Case Studies

Barratt David Wilson Homes Flood Warning System

The semi-rural Romans` Quarter development in the market town of Bingham situated in the Vale of Belvoir is located 9 miles east of Nottingham and 15 miles west of Grantham. Over a thousand 2,3,4 and 5-bedroom homes form part of the new Barratt Home development. 

As part of the region’s re-development, Barratt Homes appointed Peter Brett Associates (now part of Stantec) to oversee the construction of a new reservoir, associated dam and the re-routing of water courses. 

Archers Lake Flood Storage Reservoir was constructed with a 100,000 m³ void capacity to accommodate a one in a thousand-year flood. A deepened lake was constructed in the southern portion of the reservoir as part of planning requirements. The reservoirs spillway and Car Dyke water course was constructed from Armorloc, a concrete block revetment system of rugged composition, used for its durability to withstand all weather. 

Telemetry suppliers Lee-Dickens Ltd, working with Barratt Homes Engineering Manager Mark Potter, have introduced a Low Powered, Cloud Based, Water Level Monitoring System to help protect the new development. A tamperproof Sitewatch® remote monitoring system was installed on the newly constructed Car Dyke Culvert along Bingham’s Chapel Lane. 

“The Sitewatch system has enabled us at Barratt Homes to provide the local Water Management Team Telemetry that long term will aid their management and monitoring of the Car Dyke water level. 

An animated mimic of Car Dyke Water Course, on screen alarms, automated SMS and Email alerts will allow the reservoirs supervisory team to be proactive and not reactive enabling them to respond to any potential high-water event in good time. The monitoring systems graph will enable the management team to view historical water level data, in time building up an archive that will enable them to forecast seasonal water level activity.” 

For the Flood Warning System to retain low visibility in its public environment, battery power was preferred over renewable solutions such as wind or solar power with the battery concealed within the Telemetry’s roadside kiosk. 

Water level is monitored using a non-contact Vega C11 radar sensor located within a heavy-duty stainless-steel housing. The sensor mounted centrally over the culvert tunnel is loop powered from the Telemetry housed in a nearby roadside kiosk. 

A secure, tamperproof route for all cables was achieved using a combination of galvanised fixed and flexible conduit above ground and cable duct below ground. 

The System will provide a minimum 12-month operation between services, providing 15-minute water level updates. For differing applications, the operational period can be easily extended by selecting a larger Ampere Hour battery for service. 

The Flood Warning System self-monitors its circuits and is capable of automatically adjusting the frequency of water level updates, helping to further extend the system's operational life, until a recharged battery is introduced.
