LEAK DETECTION

Applying the latest technology and expertise gained from working in the water industry, water leak detection on underground mains is carried out by non invasive acoustic methods. A site survey will typically commence with manual sounding of the mains fittings on the site, such as valves and fire hydrants. Once a leak noise has been identified specialised electronic equipment is used to pinpoint the location of the leak.

As high consumption is not always due to a leak on the underground pipe work the main cold water risers for buildings are also sounded to establish whether there is any unaccounted for consumption by faulty fittings.

Step testing can also be carried out to quantify the flow rates along each section of main to identify which sections of main have consumption and/or leaks.

WATER CONSUMPTION MANAGEMENT

In order to monitor consumption for a site or a specific area of a site a flow data logger can be attached to the revenue meter or sub meters within the site. A logger can be a temporary installation to record flow data for several weeks to identify whether there is a high constant underlying use of water which could indicate a leak, or a logger can be installed permanently which will download data on a daily basis to a website which can be viewed by the client to monitor the meter reading and the flow profile, there by quickly identifying increases in consumption.

We also offer advice on how to cut water consumption by fitting water saving devices which are specific for the site circumstances and therefore save you money.

NETWORK ANALYSIS

A full network analysis of a site includes tracing the route of the underground mains, accurate mapping of the mains and all the external fittings, condition survey and recommendations on how to rationalise the network to lower the risk of underground leaks and to eliminate the risk from stagnant water in the mains.

Pressure logging of your network can also be carried out to identify high pressure areas where the pressure can be decreased to lower consumption and reduce wear and tear of fittings. Pressure logging can also identify areas of low pressure within a site which may indicate leaks or poor internal main condition.

PRESSURE AND FLOW TESTING

Pressure logging and flow testing of fire hydrants can be used to ascertain the pressure and flows available for fire fighting purposes in order to ensure compliance with insurance company terms and conditions.

Pressure logging and flow testing of fire hydrants can also ascertain the pressure and flows available if increased consumption within a site is required.
