Specialized Main Cleaning on School Street

The Ice Pigging project is complete and went extremely well.  The total project took 4 days and cleaned approximately 2 miles of pipe.  The picture below from right to left, shows the progression of 2 hours of cleaning 1 segment of the pipe.  For more information please visit and A youtube video is available on this process.

Service Outage notice

The Acton Water District will be conducting some necessary improvements to your drinking water supply on School Street beginning the week of October 26, 2015 from 9 am-3pm.  This procedure is an alternative to flushing mains, especially mains that might be causing issues with discolored water.  Ice Pigging is a technique that is more effective than flushing in removing particles and sediments from pipe walls.  An ice slurry is pumped through a section of main to “clean” it.  A youtube video is available for more information on this process.  While this is being done, that portion of pipe must be removed from service.  Therefore, your water service will be off while cleaning is in progress. 

During the flushing process, a small amount of sodium chloride (table salt) may enter your service line.  Customers should avoid using water during the time of the main cleaning and should run their taps for 2 to 3 minutes prior to using the water for drinking or cooking after the completion of the procedure.

If a salty taste is detected, run your tap for a longer period of time.  Generally, if you detect a cooler temperature of the water from your tap, you have sufficiently flushed out your service line.  If the water becomes very cold, continue to run your tap for an additional 2 to 3 minutes.

For Healthy individuals, the sodium intake from water is not important, because a much greater intake of sodium takes place from salt in the diet.  However sodium levels above the recommended upper limit of 50 milligrams per liter may be a concern to individuals on sodium restricted diet, or those on dialysis.
 If there are any further questions or concerns, please contact The Acton Water District
