The state-controlled National Water and Sewerage Authority (NAWASA) has embarked on the development of a new treatment plant at Mt. Agnes, St. David.

The new water facility is aimed at solving some of the water shortage problems encountered by residents in area such as Pomme Rose, La Tante, Belle Vue, Requin and Marlmount.

Residents in these areas are currently being serviced by the Pomme Rose Water Treatment Plant, which stands at an elevation of 810 feet above mean sea level and is being served by two intakes via ductile iron pipeline located approximately 2 km and 3 km up stream of the treatment plant.

The plant has rapid gravity filters, as well as a storage reservoir and disinfection system but during the rainy season, it is affected by excessively high turbid water from its intake, thus causing immediate shutting off of its entire distribution system to customers.

NAWASA has decided to address the problems of the water woes in the affected areas by vesting 4000 square feet of lands at Mt. Agnes at an elevation of approximately 1090 feet above mean sea level for the construction of a new treatment plant at a cost of EC$1.4 million dollars.

Speaking to reporters during a recent site visit, NAWASA’s Project Manager and Engineering Assistant, Dave Marquez said, the project, which started on May 25th involves the construction of a slow sand biological filter, operator’s quarters, a retaining wall (170 feet long), road works, a storage reservoir and disinfection system “close to 100ft in length” that will be able to hold a capacity of “250, 000 gallons of water per day.”

He said the hope is that residents who will be serviced by the plant would be provided with portable, reliable water in accordance with the standards of the World Health Organisation (WHO) during torrential rainfall.

The project, which has been contracted to Barriteau Enterprises, has a 9-month duration, and is expected to be complete by February 15, 2016.

Even though this is the first time Barriteau Enterprises has been contracted to work on a project of this nature, owner Alistair Barriteau expressed confidence that his workers would be able to complete the works in a timely manner, despite the one week setback experienced recently, due to heavy rainfall in the area.

According to NAWASA officials, the new water plant will have the ability to serve consumers as far away as Red Gate in St. David.
