Blok-Aid ® Sewer / Stormwater Overflow Monitoring and Alarm System Every water authority has experienced the issue of a sewer overflow at some stage. Spills can now be prevented and blockages detected early with the sewer overflow monitoring and alarm device called Blok-Aid ® . How does it work? By installing Blok-Aid ® in sewer or stormwater manholes, high sewer and stormwater levels can be detected as the level rises. An alarm is then automati- cally activated which identifies the manhole either through the Supervisory Control and Acquisition Data (SCADA) system or direct to a mobile phone or email address. Field maintenance can then be dispatched to rectify the situation before a spill occurs. With a 10 year battery life and the ability to configure the unit from your desktop, Blok-Aid ® is low voltage and completely sealed, so not only do you have peace of mind that your network is being monitored, but the device is certified Intrinsically Safe (IS). Blok-Aid ® Features • Ultra low-power with 10 yr. battery • Certified Intrinsically Safe (IS) • Proven on three continents in critical applications (USA, Australia & Asia) • Alarms via Text (SMS) Message and website in real time • Actually predicts overflows • The alarm can be escalated if not confirmed within limits set by user • Configuration downloaded to the customer site via FTP • Licensed Google Maps access for extensive geospatial information Blok-Aid ® Avoids Hassles and Expense • No special sewer lids • No local AC/DC required • No risk of explosion • No phone lines or radios to install • No antennas that snag on debris, your tools and sewer personnel • No special training classes or certification of any kind • No confined space training, certification and expense required to install • No weirs or flumes to install in sewer • No data-loggers that require on-site downloading or sync'ing • No programming or special computer software required Blok-Aid ® helps to insure against Sanitary Sewer Overflow (SSO) events and allows Sewer Managers to respond. Blok-Aid ® is so fast acting that the contact closure could operate Bascule gates downstream to prevent disaster. In Kuala Lumpur, Malaysia, Blok-Aid ® was used to control the flood gates for the Smart Tunnel - a 43.3 Ft (13.2 Meter) diameter tunnel that is used for both auto traffic and as a tunnel for flood water in storm events. In Queens, New York City, Blok-Aid® is currently being used to predict Storm Surge and unusual tidal events like Hurricane Sandy. In Singapore a network of 950 Blok-Aid® devices were installed. Each device provides early warning of possible sewer overflow conditions throughout the country. Blok-Aid® can do this for your district.
