WEDNESDAY'S rains led to major flash flooding which affected houses, businesses and public spaces.
While people were making their way home in heavy traffic, some contemplating the worst, including flooded-out homes, another stress awaiting them could be dry pipes.
WASA warned in a release that the downpours, caused by a tropical wave, have affected operations at some of its surface water treatment facilities.
Facilities in Trinidad's northern region, as well as two in Tobago, were affected up to press time.
Most water treatment plants were shut down because of high turbidity as a result of flooded rivers while others were operating with reduced production.
In its release, WASA said it was making every effort to resume normal service and promised to provide updates.
