WASA: Restrictions still in place, reservoirs remain low

Tuesday, November 5, 2019 - 13:45

The Water and Sewerage Authority (WASA) says the water-use restrictions implemented in January 2019 remains in effect.

This as the three main impounding reservoirs in Trinidad remain considerably low for this time of year, a statement by WASA notes.

WASA says the levels of storage and respective Long Term Averages (LTAs) at the authority’s impounding reservoirs as at today – Tuesday 5th November 2019 are as follows.

· Arena: 52.01%, LTA - 80.89%
· Navet: 36.42%, LTA - 80.30%
· Hollis: 44.75%, LTA - 78.71%
· Hillsborough: 100%, LTA - 92.75%

"The recovery of the impounding reservoirs in Trinidad after the harsh 2019 Dry Season, continues to be negatively impacted by below-average rainfall throughout this wet season," the WASA statement said.

WASA adds that this trend has continued during the month of October 2019 where deficits in rainfall levels were as follows:

Navet - 32.6%;
Hollis - 26%;
Arena - 8%;
and Hillsborough - 5.8%.

The cumulative shortfalls in rainfall at each reservoir in millimetres (mm) over the period January to October 2019 have been: 297 mm at Hollis; 294 mm at Navet; 120 mm at Arena; and 168 mm at Hillsborough.

"Notably, the Hollis and Navet Reservoirs, which had the highest percentage deficit in rainfall during October 2019, also have the highest cumulative shortfall for the year. As a result, production levels at both the Hollis and Navet Water Treatment Plants (WTPs) are still being maintained at approximately half of their respective capacities."

WASA: "In light of this, customers in parts of Arima (served by the Hollis WTP), as well as parts of Tableland, New Grant, Princes Town and Mayaro (served by the Navet WTP) continue to experience a reduced regularity of pipe-borne water supply. In recent days, customers in some parts of North, Central and South West Trinidad, served by the Caroni Water Treatment Plant, may have also experienced some irregularity in their water supply where production at the Plant was reduced due to reduced water availability. Adjustments have been made and operation normalized at this facility.
The Authority remains committed to minimizing the impact on customers. As such, the Authority has been closely monitoring distribution schedules and making minor adjustments where possible, as well as working with local government and other representatives, towards providing a supplemental truck borne water supply to customers in affected areas."
