We can't run without it.
You'll hear in the morning if there's a cancellation.
WPS website has the following:
MAJOR WATER MAIN BREAK MAY IMPACT SCHOOL FOR TOMORROW!
A major water main break in the city this afternoon may require an extended period of low or no water pressure throughout the city. This may impact whether we can open schools tomorrow. At 7pm, no decision has been made about school operations for tomorrow. It is possible and likely that a decision is not made until tomorrow morning. The Worcester Public Schools is in close communication with city officials regarding the repair and time frame. Once we have a better sense of the time for the repairs we will make a decision about school opening for tomorrow. Please keep updated with local media, our website, and our Twitter feed for any announcements. We will also send a Connect Ed message to homes if we cancel or delay schools. Thank you for your patience and understanding as we assess the impact on school operations.
