FEATURED PRODUCTS

Enigma® loggers are deployed at multiple positions, typically on valves or hydrants, during normal working hours. They may be programmed for either daytime or night-time operation. The loggers record the actual leak sound. When retrieved the leak sound is transferred to the host software where it is processed to display all leak positions between loggers.

The Enigma3m correlating loggers transmit daily leak noise data via the 3G or GPRS communication networks. This data is sent to a server. The data provides leak alarms and also enables the user an opportunity to listen to the noise thus helping to confirm it is leak noise. Furthermore, correlation can be performed from many loggers to accurately locate leak positions. To enable accurate correlations a daily logger time synchronization is carried out by new patented technology.

Enigma3hyQ is a variant of the Enigma3M multi-point noise correlation system utilizing 4G/3G/2G or IOT communications.

CASE STUDIES

  • Installation was completed by Farilie District Council, a rural water authority located in the central South Island of New Zealand. With a number of water supplies in the South Canterbury region, they required the latest digital noise correlation and signal coherence frequency analysis processing software. The Enigma solution was chosen to overcome challenges such as limited recoding and process capabilities.

  • The water network management team in Nantes, France is responsible for maintaining supply from a highly complex system of underground water supply pipes. Constant road traffic and restricted access make monitoring, troubleshooting, and upgrading the water network exceptionally challenging. The La Dopea (Direction des Opérateurs Publics de l'Eau et de l'Assainissement) leakage team was tasked with assessing the supply to one particular area of the Nantes Metropole area. Initial investigations indicated substantial losses, but traditional leakage detection methods had failed to identify where these were. The business challenge was identifying and preventing these leaks.

  • United Utilities supplies water to 3 million homes and 200,000 businesses in North West England. Within the Winscales and Scilly Banks service reservoir zones where the trial was to take place, local United Utilities NCI / NIA had previously split the main and quantified losses of 4 liters/sec and 2 liters/sec in the respective halves. Leak detection on trunk mains using correlation techniques has always had potentially limited success for reasons of poor sound propagation and scarcity of accessible fittings. The business challenge was to exceed these limitations, improve efficiency and reduce leakage.

  • The State of Texas and the region around Abilene in particular has been experiencing an ongoing drought. Abilene takes the region’s need for adequate water supplies seriously and has been analyzing the short-term water needs (5-10years) as well as the long-term water needs (+50years) for its service area. The ongoing drought had pulled the three primary water supply reservoirs for the region down to extremely low levels. In the autumn of 2014: Lake OH Ivie was at 15% capacity; Hubbard Creek Reservoir was at 16% capacity; Lake Fort Phantom Hill was at 32% capacity.

  • Leak location on large diameter mains is difficult because the pipe becomes more elastic as the ratio of pipe wall thickness to diameter increases. This results in more rapid absorption of leak energy into the pipe material, with resultant attenuation as distance from the leak increases.

  • Ten Enigma3m loggers were installed in less than two hours on sites located in the city of Lyon. The devices are equipped with a roaming SIM allowing the Enigma3M to select the best GSM network. Some holes were created in the chamber for fitting the aerial and optimizing the GSM data for transmission.

  • The Ventura River County Water District in Ojai, California required a new SCADA system but they were keen to ensure that a computer did not have the ultimate destiny in the dispatch of very necessary alarms.

    The customer wanted a solution that provided “fail safe” operation whilst minimising the impact of single and multi component failures during system operation. Here, the business challenge was to reduce downtime and improve efficiency and situational awareness for the Ventura River County Water District.

  • Ranhill SAJ Sdn Bhd, a subsidiary of Ranhill Holdings Berhad, is an integrated water supply company in Malaysia, involved in the process of water treatment and distribution of treated water to consumers right up to billing and collection. It serves around 3.1 million population and manages 22,175 km of pipes over an area of approximately 19,000k m².

  • Anglian Water has reduced leakage by 20% since 2010 and has committed to a further 23% reduction by 2025. Overwhelmingly, customers have told Anglian Water that leakage is a high priority and that they want to see it reduced to well below the Economic Level of Leakage (ELL).

    The aim was to develop, own and utilize a system that enables cost-effective, smart, real-time leakage monitoring at an individual asset level for Anglian Water's entire network. The team was faced with a multitude of challenging conditions; the sites consisted of a large range of materials, including but not limited to Cast Iron, Ductile Iron, Asbestos Cement, MDPE, and PVC.
