vi UK Focus - Water / Wastewater New £4m camera contract helps manage fl ood and coastal risk
Following a competitive tendering process, Meteor Communications has been awarded a four-year contract by the Environment Agency to signifi cantly expand their estate of low-power remote image collection cameras. Installed at strategic locations, the cameras will provide critically important information on the status of water management assets involved in reducing fl ood and coastal risk.
Under the contract, Meteor will provide the Agency with hourly images of remote assets such as grilles, screens, storm overfl ows, channels, culverts, pumps, gates and automated structures. The images will be captured by Meteor’s remote cameras (MRC) and delivered to Agency staff via the company’s web-based MeteorCloud service.
This award builds on previous contracts under which Meteor has installed around 1,500 remote cameras for the Environment Agency. Images from the MRC cameras provide Agency staff with an early warning of potentially harmful or dangerous conditions. For example, the immediate visual confi rmation of rising water levels in storm drains or blocked trash screens allows a rapid and timely response. Equally, for asset management regular real-time images from site
reduces the number of site visits, saving time and money. It has been estimated that by avoiding unnecessary journeys, each MRC camera saves around 0.5 tonnes of carbon dioxide emissions per year, and each camera’s fi nancial payback is just 9 to 10 months.
Explaining the particular advantages of the MRC cameras, Meteor’s Managing Director Matt Dibbs says: “Our main focus in the development of these cameras was the ability to operate unattended in remote locations where normal power and communications may not be available. The MRC cameras therefore operate on ultra-low power, requiring just a small battery and a solar panel for year-round operation, anywhere in the UK. This dramatically reduces installation time and cost.
“Transmitting single high-resolution images, the cameras are able to operate via any mobile network connection. This means that high-quality, real-time images can be provided even in areas with poor mobile coverage, and with an extremely robust design, they are suitable for long term, unattended operation with minimal maintenance.”
In addition to the scheduled images, users are able to request additional pictures via the MeteorCloud® web portal, directly by SMS or email. This includes requests for an enhanced (faster) polling mode for a set period of time, which can also be prompted automatically – by a connected water level sensor for example. This means that rising water levels can cause the camera to raise an alarm with an accompanying image to provide visual confi rmation of conditions.
To ensure that the system is resilient and futureproof, Meteor also provides full integration of the MRC camera system (via the Meteor Data Centre) into the Environment Agency’s current SCADA platforms and future visualisation systems.
Andrew Pearce, the Environment Agency’s deputy director for asset management systems, said: “Our new fl ood defences have already better protected 314,000 homes since 2015 and we’re going further, delivering a record £5.2bn investment to protect hundreds of thousands more properties.
“Working with Meteor Communications and these new remote cameras will help us to maintain defences to ensure communities remain protected, as well as save money, improve effi ciencies and lower the carbon footprint of our operations.”
Meteor Communications currently has around 2,500 MRC cameras operational in the UK.
MRC camera systems are in use across the Water Utilities sector, Local Authorities and Network Rail for remote operational and asset management purposes.

Using Valeport’s world-leading high accuracy sensor technology to combine sensors for multiple profi les in a single drop, the SWiFT Deep CTD can operate to 6000m, delivering directly measured conductivity, temperature and depth. In addition, the SWiFT Deep CTD will provide computed salinity, density and sound velocity, calculated using the UNESCO international standard algorithm and Chen and Millero equation. Data can be quickly and easily downloaded wirelessly, and instantly shared in industry standard data formats.
Ease of use is at the heart of the SWiFT range and the new SWiFT Deep CTD not only makes any problematic battery changes a thing of the past and delivers fully automated data transfer with no user input required, it also features Valeport’s signature SWiFT magnetic switch ring. The switch ring is easy to operate even with cold hands, it simply turns through 90 degrees and reassuringly clicks into position. The end cap features user-friendly LED status indications for GNSS, battery and communications.
With an operational battery life of up to fi ve days and the convenience of charge via USB, the SWiFT Deep CTD is designed to cope with the harshest conditions and intended for offshore, coastal, harbour and inland environmental and hydrographic survey use.
Providing unmatched durability, the SWiFT Deep CTD is constructed from titanium and the CTD sensors are housed in a strong acetal sensor guard.
