Water Leak Detection

Cutting leakage from underground water pipes can have a significant environmental impact. Preventing, finding and repairing leaks reduces extraction from natural sources and cuts demand for more treatment plants to be built. In many countries, reducing leakage can alleviate drought measures. Find out more by visiting the Palmer Environmental Ltd, Hydreka SAS and Fluid Conservation Systems Inc web sites.

Pinpointing underground pipe leaks

Our latest leak location instruments use state-of-the-art digital signal analysis to pinpoint the location of an underground pipe leak to within 1 metre. Acoustic detection instruments let water companies trace underground leaks with a minimum of digging. Here an engineer listens for leak noise with a highly sensitive ground microphone

Saving water, saving money

Permanently installed leak noise loggers can dramatically cut leakage water loss. These instruments attach to underground pipe fittings and transmit leak data by radio signals to a handheld or vehicle-mounted radio receiver. During 2004 Halma leak noise loggers installed throughout the city of Las Vegas, USA, detected 253 leaks, saved 65 million gallons of water and cut $100,000 in electricity costs.

Reducing the likelihood of pipe bursts

Water companies in many countries use Halma electronic pressure controllers to prevent bursts in underground water pipes. These instruments measure and locally adjust water pressure to protect distribution networks from damage.

Using Halma automatic pressure controllers, Bristol Water, UK, maintains a continuous supply for customers in its hilly territory while preventing high water pressures that could burst pipes.
