SENSOR DDS® leak location systems in water industry
In the water industry there are many applications for SENSOR DDS® leak detection & location systems.
Dirty water:
- Covered Anaerobic Lagoons
- Evaporation ponds
- Waste thickeners
- Storm tanks
Clean water:
- Service reservoirs / Potable Water Storage Tanks
- Lakes / Impounding Reservoirs
- Chemical Free Water Treatment Lagoons
For special requirements in potable water industry we have developed a system design which meets all high standards required in this industry. We call it SENSORLINE®
Sensorline® is a potable water system that is Regulation 31 Approved for contact with potable water, the use of Sensorline® enables the detection and location of leaks from potable water storage facilities. Sensorline® is available in thicknesses ranging from 0.75mm to 2,5mm and comes in smooth or non-slip finishes.
In addition to potable water storage applications Sensorline® can be deployed for the protection of raw water storage facilities such as impounding reservoirs and lakes due to its wide roll format that serves to increase the speed of installation by minimising site welding.
Sensorline® rolls can be cut down to any required width dimension for use on smaller sites where handling of large rolls is inappropriate or where the rolls must be manoeuvred into storage tanks for deployment.
Non-slip versions of Sensorline® can be used on the floors of potable water tanks to prevent slips and falls of maintenance operatives during cleaning operations.
Sensorline® is a tough material that is highly resistant to punctures which allows surfaces lined with Sensorline® to be cleaned using high pressure water jets without fear of damaging the liner.
The following case study of the Cal Lagoon demonstrates the effectiveness of Sensorline® in providing long-term containment integrity and early leak detection
CAL Lagoon in England – SENSOR DDS® Fixed Installation (SENSOR DDS® RMS)
General project info:
- Industrial waste from manufacturing facility
- Area of 20 000m²
- SENSOR DDS® RMS 24/7 monitoring installed with Sensorline®
- Sensor grid 5x5m (leak resolution cca 25m²)
- 800 sensors and 78 km of cable used
- Double lining system Sensorline® 1.00mm
CAL lagoons are specifically designed to control odours and must satisfy a number of design criteria like for example:
- Stop rainfall to the lagoon
- Eliminate effect of the wind
- Ability to de-gas covered lagoon
- Eliminate accumulation of scum, fats, oils and grease under the cover
- Prevent leakage
We applied our standard SZLP (Sensor Zero Leakage Philosophy) at this lagoon, which included installing a permanent leak monitoring system and monitoring lagoon construction and filling, consisting of:
- SENSOR DDS® FIXED – buried components installation in grid of 5x5m
- SENSOR DDS® MIT – survey of both layers of geomembranes after their installation to locate any pinholes made during installation or transport
of Geomembrane. Both Geomembranes were monitored 24/7 during lagoon filling up process and during operations using SENSOR DDS® RMS.
SENSOR DDS® RMS installed on site has following features:
- Online remote connectivity
- 24/7 geomembrane monitoring
- Live alerts by SMS/Email
- Full access via Sensor Cloud
- Rapid resolution of leaks
- Security camera
- Weather station
- 10″ full HD touch display
- 12 months events list
- Battery backup for 3 days
During the lagoon filling process, our system detected a leak within the secondary geomembrane and automatically triggered an alarm, subsequently notifying the client. The precise location of the leak was then reported to the client within 48 hours, where it was determined to be a pre-existing client test hole.
Since installation in 2018 SENSOR DDS® RMS leak detection and location system monitors the lagoon 24/7.
Sensor's zero leak philosophy can be applied to water reservoirs, lakes, lagoons and other industrial and non-industrial water storage ponds.
