Outfall channels being dredged as rains threaten
A number of works are being urgently engaged as conditions related to the El Niño phenomenon wind down and rains threaten.
These works include the dredging of outfall channels around the city, since most of these channels were silted up during the prolonged dry period.
According to the Ministry of Agriculture yesterday, the interventions will allow for an improved gravity flow with greater hydraulic efficiency through the sluices, which in turn will help to faster discharging of larger volumes of water at low tides.
Pieces of equipment belonging to the Ministry’s National Drainage and Irrigation Authority (NDIA) are providing support to the Mayor and City Council (M&CC) of Georgetown.
A pontoon, with an excavator for the carrying out the critical works is already in operation and the M&CC has provided another excavator to facilitate the desilting works.
Dredging has begun at the Cowan Street outfall after which the equipment would move to the Kingston outfall. In addition, the NDIA through its Community Drainage and Irrigation Project has been working to clean and clear key drains and canals around the city. Workers under the project have also been providing support by cleaning parapets, weeding bushes along and around key canals and clearing garbage from critical drains and trenches. Areas where these works have taken place are Meadow Bank, Kingston, West Ruimveldt, East Ruimveldt, East La Penitence and North Ruimveldt.
According to the Ministry, the NDIA has also assisted the M&CC to ensure both the Liliendaal and Kitty pumps are fully operational which for the greater part would increase the drainage capacity in the city. In the past, the NDIA has supported the M&CC with mobile drainage pumps which have been deployed at various sites, along with excavation of drainage canals in areas such as Sophia, Turkeyen and Downer Canal.
Also, government has assisted the M&CC with the rehabilitation of the Liliendaal and Kitty Pump Stations to increase its discharge capacity, to the tune of $140M. NDIA yesterday also urged that garbage should not be dumped into drains and trenches since it could lead to blockage and minimize effective drainage, resulting in flooding.
