Flushing the Waterworks System

Flushing consists of increasing the flow and reversing the direction of the flow in order to clean the underground pipes in a particular area, which maintains the quality of the drinking water distribution service. This does not affect the quality of the water, which can still be safely consumed.

Sometimes the water may be less clear when you first turn on the faucets or washing machine. To correct this, just turn on all the cold faucets for a few minutes until the water runs clear.
