A new system for automatically flushing water lines can be controlled by chlorine residual levels or water quality management devices. The system can be directed to flush water lines only when it is critical for the maintenance of water quality standards and should help municipalities who are challenged by the need to flush their distribution lines but are restricted by the existence of local or state water conservation legislation.

Environmental Enhancement & Technologies launched its Hydro-Guard® S.M.A.R. T. (System Management Assisted by Remote Telemetry) Flushing System during the American Water Works Association’s annual conference in June.

The flushing system allows for two way communication and remote flushing unit management via either a secure web portal or an interface with the utility’s existing SCADA. By way of this two way communication, operators can receive real-time updates from each Hydro-Guard-equipped S.M.A.R.T. unit in their system.

The flushing system can be integrated with a chlorine residual analyzer and a variety of other water quality management devices, including pH and turbidity monitors. This integration will allow the system to flush when the disinfectant residual drops below the parameters established by the end-user as opposed to flushing on a time based schedule. As an added benefit, time based programming functionality is included in the flushing system so that the end-user can have maximum control over the flushing program from on-site or a remote monitoring location.

Supervisory software is available to integrate multiple controllers into an overall system. The software will allow users to view data from multiple controllers, store data to a local database, display all S.M.A.R.T. system units on a map, and more.

“As has always been true for Hydro-Guard’s line of products, the Hydro-Guard® S.M.A.R.T. flushing system will increase thee amount of water, time and money a utility can save as part of the management of its flushing program,” said Thomas M. Taylor, P.E., President and CEO of Hydro-Guard®.

The flushing system is available in two primary models: one battery powered and the other powered by 120-volt AC. The low-power battery operated model uses a C-type battery that offers a two year life span and has been designed with a redundant battery too reduce the chance of a power failure.

Both models are compatible with most residual analyzers and SCADA technology. Utilities operating without SCADA can use cellular communication to implement two-way communication between the operator and the Hydro-Guard® via a secure web based portal.

The system has been designed so that the controller can be retrofitted to any existing automatic flushing system, with the exception of the Hydro-Guard® HGG-6 Hydrant Based Flushing System.

Environmental Enhancement and Technology USA Inc. was founded in 1998 in Naples, FL. That same year, the company patented its first automatic and programmable flushing system, the Hydro-Guard® HG-1. Today, the company offers 10 flushing system models and has thousands of flushing systems in operation throughout the U.S., Canada, Guam, the Virgin Islands, and Puerto Rico.
