Harford Park is also in the midst of an upgrade to its potable water infrastructure. The first stage of the project is the replacement of the main lines which is almost completed. The next stage will tie in the individual houses to the main lines. As main lines are completed, they will be chlorinated to kill pathogens, flushed, and tested, before connecting to homes. Each homeowner will be notified by letter when their connection will occur as service will be briefly disrupted.
