Installation of Fire Hydrant/Valve - Water Service Interruption: Milford Rd/Pennichuck Square Area


July 6, 2023

MVD recommends filling tubs and/or buckets for sanitation purposes prior to the service interruption.
Water may be discolored when restored. Discolored water is typically caused by sediment, such as iron. Although discolored water is not aesthetically pleasing it is not unsafe* and can be easily resolved by flushing the water service line to the property. Flushing allows a larger than normal quantity of water to flow through the service line, which helps, clear out the sediment. You may notice the discoloration return after the water has sat in the lines for a period of time, such as overnight or during the day if it’s not being used – this is to be expected. When the water is not used for a longer period of time the sediment settles, when water is turned on it is agitated and the discoloration returns. If this happens, you may repeat the flushing process. If your water is discolored, we recommend avoiding the use of hot water until the cold water is clear. If you have used hot water prior to/during flushing and are noticing discoloration in the hot water, the water heater may need to be flushed – refer to the manufacturer’s manual for instructions or contact a licensed plumber.
*Some people may be more vulnerable to contaminants in drinking water than the general population. These people should seek advice about from their health care providers.
