The 1st Response sewer overflow prevention/backup monitor from Eastech Flow Controls alerts municipal personnel within seconds of an impending overflow condition. A level switch combined with cellular text technology is installed within the suspect manhole, and upon wastewater levels reaching a specific user-defined height, a text message is dispatched alerting field crews of the possibility of a surcharge event. To confirm that an alert was received, a user response must be activated, otherwise the alert will be re-sent on a continual basis. All electronics are self-contained within a corrosion-resistant Nema 4, 4X enclosure, submersible-rated to IP-67 standards. The unit mounts securely to the top of any ladder rung without the need for confined-space entry. Installation within the manhole is accomplished in approximately five minutes. 800/226-3569; www.eastechflow.com.
