DELRAY BEACH, FL (Boca Post) (Copyright © 2026) — A construction mistake near Delray Beach’s water treatment plant Friday forced the city to juggle repairs, water-use limits, and a temporary shift in how drinking water is disinfected.
City officials said a contractor working on a deep injection well “mistakenly caused a pipeline break.” Water showed up on the west side of the Water Treatment Plant along SW 4th Avenue. Not a great sight.
Until repairs are finished, the city is asking residents and businesses to ease up. Limit non-essential water use. Skip irrigation. No car washing. The idea is to keep pressure steady while crews deal with the damage.
To hold the system together, Delray Beach said it is temporarily using an interconnect with Palm Beach County. Along with that comes a change in treatment. The city began using free chlorine immediately, earlier than planned, to support system reliability during repairs.
That free chlorine period had already been on the calendar. It was supposed to run from Monday, Jan. 5, 2026, through Saturday, Jan. 24, 2026. Instead, it started right away.
Most customers probably won’t notice much beyond a possible change in taste or smell. The city said that can happen when disinfectant practices shift. It’s normal, but noticeable to some.
Later in the afternoon, another update went out as the situation widened. Because of the raw water main break, Delray Beach temporarily opened emergency water interconnections with the City of Boca Raton and the City of Boynton Beach to maintain service.
Water coming through those interconnections is disinfected with chloramine rather than free chlorine, which is what Delray Beach normally uses. The city described the notice as precautionary. Officials said there are no known health effects tied to the temporary change, and that the water continues to meet state and federal drinking water standards. Most customers, they said, won’t notice a difference.
Still, there are exceptions. Always are.
Residents who use home dialysis machines, keep aquarium fish, or operate stores or restaurants with fish and shellfish holding tanks were urged to get professional guidance on how to remove chlorine from tap water. Chlorine and aquatic life don’t mix well, and dialysis systems can be sensitive too.
The city said it will keep customers updated as repairs move forward and will notify the public once normal operations are restored.
For now, it’s a waiting game. And a conservation ask.

UPDATE (Thursday, Jan. 8, 2026 — 6:18 a.m.)
Delray Beach is asking residents and businesses to keep irrigation systems off for another 72 hours, through Saturday, Jan. 10.
It’s a precaution while crews keep working on repairs near the city’s water treatment plant, off SW 4th Avenue. Outdoor water usage reduction helps protect water system pressure while preventing the need for boil water notice requirements. Nobody wants that.
The city maintains service continuity through its establishment of emergency water supply lines which connect to Boca Raton and Boynton Beach. The planned free chlorine period also started early — Saturday, Jan. 3 — instead of Jan. 5, to help stabilize the system during repairs.
Most people won’t notice much. The experience would result in a minimal change of how things taste and smell. That happens.
Home dialysis users and aquarium owners and fish and shellfish tank operators need to follow safety protocols when they receive guidance about chlorine removal.
City officials state that construction work remains active while they will distribute additional project information in the future. For now, conserve.
