When a flash flood hits the West Bayou Oak subdivision in Houston, residents have only minutes to remove their vehicles from the parking area. In the past 10 years, the townhomes have had several vehicles totaled or severely damaged plus numerous repairs. In South Texas and Louisiana, spring ’16 had severe flooding. Curtiss Beinhorn, a resident, reports that “approximately 70 cars were totaled in the April 18, 2016 flood. “Insurance claims and rates are out the roof.” Turkey Creek is a tributary that comes off some major rivers. Houston’s weather pattern ‘sandwiches’ the area from two directions: San Antonio Hill Country (north) and from the gulf (south). Flooding has always occurred at night; residents only have minutes to move their cars. Curtiss decided to explore various flood systems. Working with ELTEC, it was determined that a pressure sensor (creek debris could wash it away) or cell modem (overkill) was not the best solution. “We needed a real time alarm system in the form of a siren.” The two pole system is solar powered: sensor unit with power accessories and sirens, wired to a second pole on higher ground containing a toggle switch inside a secured cabinet allowing a resident to disable the sirens. ELTEC’s unique water sensor (immune to trash and debris) is mounted on a pole placed at the lower end of the parking area. The creek’s rising waters triggers the sirens alerting residents 24/7. The sirens are ON for 10 seconds, OFF for 10 seconds, until someone flips the toggle switch to turn OFF. Every ELTEC flood detection system is customized. Between customer service and product technology, the residence now have an effective flood warning system. Contact ELTEC to work with you on a flood system quote.

High Water (IMSA Jan-Feb ’09)

Electrotechnics’ (ELTEC) High Water Warning System with Alert Messaging

It seems with every national weather forecast, some state is experiencing extreme weather of some type: record high or low temperatures, record number of tornadoes, and/or tremendous flooding breaking all previous accounts in recorded history.

High water kills and when it’s ‘raining cats and dogs’ it’s difficult to see if the road is truly swamped. Every state has areas or roads that experiences occasional flooding. For those sites, ELTEC has developed a low maintenance HIGH WATER WARNING SYSTEM.

ELTEC’s system (FS-2AHW) utilizes pole mounted sensors housed in galvanized piping positioned at the desired high water detection point. When water touches and rises above the sensor level, the two stain-less steel electrodes send a signal to the transmitter, which in turn actives the solar powered flashing road beacons. The LED’s flash continuously as long as the flood waters are detected.
The benefits of ELTEC’s ‘better mousetrap’ are:

  • No moving parts; mechanical float switches can jam
  • Immune to trash and debris
  • Doesn’t wear out (no mechanical float switches)
  • Immune to corrosion/won’t rust
  • Operates in salt/sea, brackish and fresh waters
  • Waterproof pole housing; wires not exposed to water
  • Stand-alone: solar powered

An optional feature is available enhancing its’ value. The system can be equipped with a radio service which connects to the internet and then sends alerting emails. It can also be programmed to make phone calls with a recorded message announcing the specific site that’s flooded.

Each system is sized and customized to insure optimal performance.
