Several of the Water and Sewerage Authority's Water Treatment Plants will remain out of operation due to issues such as turbid river conditions, clogged intake screens and power failures caused by heavy rainfall over the past 48 hours.
The affected areas include Tacarigua, Toco, Santa Rosa Heights in Arima and Delaford in Tobago.
The impacted facilities will return to service based on the normalization of conditions at each location, WASA stated.
"In light of this, customers are advised to manage their water use efficiently, as it may take up to 24 hours after restart of operations for the restoration of their scheduled pipe borne water supply," WASA stated.
"The Authority wishes to assure customers that the water currently being supplied complies with the Guidelines for Drinking Water Quality of the World Health Organisation and is safe for use," it stated.
For further information or assistance, customers are asked to contact WASA’s Customer Call Centre toll free at 800-4420/26.
A limited truck-borne water service will be available with priority given to special homes and health care institutions.
