A.L.F. is a cost effective, automatic, programmable, 

solar charged water line flushing device that 

operates independently and helps ensure safe, 

high quality drinking water that meets or exceeds 

federal and state regulations. A.L.F. is especially 

suited for:

•Long, low-demand water mains
•Dead-end water lines
•Looped water lines
•Intermittent use water lines
•Any water line where water may become stale

A.L.F. eliminates the need to provide staff and 

vehicles to manually flush water lines. It can be 

programmed to flush on a specific day(s) of the 

week, time of day, and duration desired without the 

need of special tools.

Automatic Waterline Flushing Device

This appurtenance is designed for installation onto the end of a waterline, or installed intermittently along low demand sections of water distribution mains. It is designed to automatically flush the line at a preset time and duration, and record gallons flushed (optional). Regulations require all distribution authorities to flush their water lines annually to ensure removal of sediment and biofilm growth. Select waterline segments are required to be flushed more frequently to ensure fresh water in sections of low or nonexistent demand. Regulations also require authorities to record the gallons flushed as part of their unaccounted water report. Previously, water distribution systems have scheduled personnel to physically actuate valves and hydrants and estimate gallons flushed. A.L.F. meets the goals by automatically flushing the waterline and recording the gallons flushed without the need for maintenance personnel.

How It Works

A.L.F. is programmed to flush on a specific day(s) of the week, time of day, and for the specified duration (up to 99 minutes per flush) based upon the site requirements to maintain fresh water within the distribution line. Programming can be accomplished prior to installation or changed at any time in the field. This is accomplished with the self-contained controller – without the need of a computer or special tools. In the event of power failure, a backup battery retains memory of preset values. The controller is conveniently located inside the lockable control panel. The 12-volt battery is maintained by a solar or photovoltaic panel. At the programmed time, the controller opens the solenoid valve and waterline flushing commences. After the programmed duration, the controller closes the solenoid valve and waterline flushing ceases. Water sampling of the waterline may be accomplished by manually operating the A.L.F. and performing the sampling, without disrupting the programmed schedule. An optional water meter can be installed in the line to monitor gallons flushed or gpm, and readings can be recorded by meter readers.
