USA – LOG N3 & GT3-S Mobile Remote Network – GPS synched Mobile Solution with Online Correlation & Theft Guard

Miami-Dade Country FL
Professional water loss reduction (1)

GPS synchronized remote monitoring

Description
In 2019 the Miami-Dade Water Department began using the
GT3-S network for water conservation efforts.
SebaKMT provided the water department with a solution for
heavily trafficked corridors throughout Miami-Dade County.
The GT3-S network was immediately received with high marks. Very much like the Sebalog N-3 network it also provided
accurate leak data via the SebaCloud platform. A significant reduction in deployment time was readily apparent due to the ease of installation of the LOGN3 + GT3-S network. Sound files were clear and audible.
Another excellent feature of the GT3-S is the integrated GPS. It allows for options such as theft protection to help track unauthorized movement of devices. SebaKMT has engineered a quality product in the GT3-S that provides clients with the ease of on-site troubleshooting of the GT3-S transceiver and therefore prolonging the life of the remote network and its components. SebaKMT continues to provide accurate, efficient and technologically advanced solutions for any department that is aggressively engaged in water conservation efforts.
The Miami-Dade Water Department has been deploying the
LOGN3 + GT3-S network since beginning of 2019.

Professional water loss reduction (2)

Permanent remote monitoring

Description
In 2015 The Miami-Dade Water Department was in search of remote leak monitoring solutions for their water distribution system in heavily trafficked areas.
The department was introduced to the Sebalog N-3 remote monitoring system that could be deployed throughout the water network. While piloting the product, the system provided crucial and time saving information for areas with heavy traffic within Miami-Dade.
Since then operators were able to monitor areas via the user-friendly SebaCloud platform. Setup and installation were manageable. Miami-Dade was pleased with the systems performance and its ability to meticulously provide leakage data.
Sound files were clear and audible.
The installed leak monitoring system Sebalog N3 provided leak  data that would have gone undiscovered otherwise and saved millions of gallons of water.
This system was deployed for 4 years.

Erwin Utilities, TN
Professional water loss reduction

Advanced and efficient leak locating

Description

In June 2019, Erwin Utilities purchased the latest SebaKMT leak detection equipment. They began using the equipment and have located and repaired 39 water main breaks since that time.
The utility’s AWWA M36 water audits show that real losses added up to 135.691 MG in FY19, just prior to the implementation of SebaKMT leak detection equipment.
In FY20, the utility was able to reduce real water losses to 79.333 MG, a savings of 56.361 MG for the Fiscal Year. According to the water audit which uses variable production costs, the utility achieved savings of $36,558 using SebaKMT’s state of the art leak detection gear to reduce real losses. Erwin Utilities is in the process of implementing an Automated
Meter Infrastructure (AMI) system with a SebaKMT fixed base leak detection system (Leak Spy). The remote monitoring acoustic system will help the utility to reduce real water losses further with less manpower.
Jim Divido with SebaKMT trained the utility personnel and located 5 main line leaks during the demonstration and training period. The customer service, training and personal attention that SebaKMT has provided to help Erwin Utilities improve their water loss reduction program has been second to none.

Water loss reduction at the City of Clyde
(Kansas, USA)

Leak locating

Description

The City of Clyde, Kansas, contacted Kansas Rural Water Association (KRWA) Circuit Rider Greg Metz requesting assistance for a leak investigation. Greg Metz made himself available the same day on site.

The City of Clyde is located in Clay County in north-central Kansas.

The City uses groundwater as the main source of water supply. The water plant provides continuous disinfection.

City operators had noticed an excessive amount of water coming out of a storm drain into a creek and the usage at the water plant had significantly increased the day before.

Circuit Rider Greg Metz was able to utilize Kansas Rural Water Association equipment (SebaKMT HL 7000 ground mic) to identify a leak sound on a four-inch main just up the street from the storm drain. Greg returned the next day and with the help of the SebaKMT P1 / HL6000 pinpointing correlator and the wind protected ground mic HL 7000, he was able to pinpoint the leak within 1 inch. The leak was estimated to be more than 20 gallons per minute of lost drinking water.

Following the repair of the leak, the discharge from the storm drain discontinued. The cost of drinking water is approximately $2.00 per 1,000 gallons (production cost). The daily loss was more than 20,000 gallons. The annual cost of the leakage would be approximately $20,000. The loss of water revenue is much higher. The KRWA helps cities with less than 10,000 people to keep their water supply under control.

USA - Sebalog N-3 Network - Smart Network Noise Loggers

You simply magnetically attach a logger on top of the operating unit, and then close it,
and it does its job! (Angel Bustamante, water systems division manager for EPWater)

 

Sebalog N-3 Network

Smart Network Noise Loggers

Description

El Paso Water is on the hunt – for leaks. Since 2004, EPWater has purchased and installed thousands of sensors to track
down leaks and make repairs before a main break can occur. With more than 2,600 miles of water distribution lines, the sensors,
known as loggers, have proven to be a valuable asset in maintaining lines and improving the reliability of water
service. In the past four years, EPWater saved an estimated 183 million gallons of water thanks to the technology.
“We have 12,000 of these loggers that are deployed around the city,” said Angel Bustamante, water systems division manager for EPWater. “In the street there are a series of valve boxes that can be opened; you simply magnetically attach a logger on top of the operating unit, and then close it, and it does its job.” The waterproof loggers are programmed to “listen” for frequencies and decibels specific to leaks in all types of water lines. The contractor will investigate further with headphones and a well-practiced ear to confirm the leak at the site. “It sounds a little bit between a mix of a humming noise and a running water kind of noise,” explained Bustamante.

Switzerland - Sebalog N-3 Network - Network of correlating noise loggers

Leak found through precise pinpointing: Sustained minimisation of drinking water losses

Sebalog N-3 Network

Network of correlating noise loggers

Description
In December 2015, our Swiss sales partner Riwatec installed noise loggers at the Bern train station to detect leaks in the
station’s drinking water supply. The loggers send data wirelessly on a daily basis to the GSM box with integrated SIM card. From there, the data is sent to an FTP server which the user can access online in the SebaCloud.

Directly following the installation, three leaks were detected in this way. One of these was a constant 30 l/min “continual leak” that for years had caused visible moisture damage in the Underground passageways to the platforms. The leak was able to be precisely located through the services of the Riwatec company. Since this leakage was directly under a track bed at platform 6 and the repairs turned out to be very costly, this line was taken out of service until repaired. For the SBB this was a complete success, since leak localisation is made extremely difficult by the constant background noise.

Australia – Sebalog N-3 – Correlating network noise loggers

Sebalog N-3

Correlating network noise loggers

Description
Monitoring of trunk mains in remote areas can be very expensive, due to the amount of time that is needed to access the site before leak inspection can begin. Furthermore, the large diameters of trunk mains represent a problem for many conventional acoustic leak detection systems. Despite these challenges it is important to closely monitor trunk mains, as leaks on such pipes can lead to great water losses, and in the worst case, to pipe bursts. SebaKMT’s fixed network of correlating noise loggers enables both the remote monitoring of trunk mains and the exact location of leaks, even on large diameter pipes.

» Remote leak monitoring and pinpointing
» Transmission of acoustic recordings for correlation
» Advanced web-based evaluation software
» Adaptable to existing SCADA systems
» Cascading repeater functionality

Within the first months of the installation for Wingecarribee Shire Council several leaks were identified by the N3 system and later verified in the field, saving the community a lot of water, and a lot of money.

Germany – Sebalog HydroCorr – Correlating noise loggers with hydrophone sensors

Sebalog HydroCorr

Correlating noise loggers with hydrophone sensors

Description
In mid-November, flow measurements by the regional water supplier in Stuttgart revealed the likelihood of a major leak in a DN 900 grey cast iron water main. Pressure measurements were carried out along the pipeline and the location of the suspected leak was narrowed down to a section of approximately 250 metres. To find the exact position of the leak, a Sebalog HydroCorr system was used, consisting of correlating noise loggers with hydrophone sensors. Although the pressure in the pipe was only around 1.5  bar, it was possible to carry out a successful measurement and receive a definite correlation result. The following pipe excavation confirmed the correlated leak location, revealing a 5 metre-long crack in the bottom of the pipe.

Sebalog N-3

Correlating network noise loggers

Description
In 2004, the public utility company Gleisdorf employed the firstnoise level loggers in its water pipe network, thus initiating the electronic age of permanent water loss monitoring. 156 Sebalog N-3 units are currently in use in the Gleisdorf water pipe network. In the 8 years of operation, annual water loss was able to be reduced from 30% to 2%. This spares a yearly water loss of approx. 29,000 m³ which would cost around € 19,000. This reduction in the loss was possible because the noise levelloggers can detect the smallest leak immediately. By detecting these early, greater damage is prevented and thus unnecessarily long leakage durations avoided.

Leakages detected with minimal expense using the starter set

Sebalog N-3 & Sebalog Corr

Noise level logger starter set and multi-correlator

Description
While searching for drinking water losses of 20.4 m³/day in the upper section of the town of Wächtersbach/Hessen, the powerful duo Sebalog N-3 (noise level logger) and Sebalog Corr (multicorrelator) turned out to be a real stroke of luck.

The noise level loggers as well as the multi-correlators were planted in the zone on valves in the drinking water pipeline for the purposes of measurement so the data recorded could be analysed the following day. By using these devices, approx. 3 km of the pipe network was able to be checked with one measurement.

Using the analysed data, the leakage was able to be clearly isolated to one pipe section. Using the correlation function of the Sebalog Corr sensors, the leak was able to be measured and located with precision.

Sebalog N-3 Network

Noise level and frequency logger with remote reading and correlation

Description
The community of Mömlingen needs to reduce the high costs of commissioning the tracing of leaks in the drinking water network. The duration of the leaks must also be minimized because preparing drinking water is an expensive process. With this in mind, a network of 25 Sebalog N-3 loggers was installed at the beginning of March 2013 for trial. After running for 7 weeks and a sudden increase in night-time consumption by 120 m³/day for a total pumped quantity of 480 m³, two leakages could be detected directly using the remote reading. The correlation function of the network was even able to identify the faulty house connection. It only took 7 days, from the time the leaks began until they were repaired. With the knowledge gathered on how modern leak monitoring can function today, the system was extended to 100 permanently installed network loggers.

Correlux P-2 and HL 5000

Correlator and ground microphone for pinpointing leaks

Description
The leak detection team in Dubai have become experts at detecting leaks with SebaKMT equipment. Leaks that are very close to each other are often hard to identify. But using the SebaKMT Correlux P-2 correlator they were able to locate two leaks neighbouring each other. The following excavation work showed how accurately they had pinpointed both leaks. The correlator Correlux P-2 is used for leak location on pipes for portable water. Water escaping from a leak under pressure creates a noise which travels into both directions of the pipe. This noise is recorded by two sensors attached to the pipe (valves, hydrants), amplified and transmitted to the correlator. The Correlux P-2 compares both signals (correlation) and calculates the exact distance to the leak by use of the signal delay, the sensor distance and the sound velocity. With the Hydrolux equipment HL 5000 you can find leaks particularly quickly, easily and reliably. The equipment uses modern digital signal processing technology to clearly recognise the leak sound, even when there is a lot of noise in the environment.
