Hillsborough Reservoir

The Hillsborough Reservoir is the only constructed reservoir in Tobago. Standing one hundred (100) feet above sea level, it was built by impounding the waters of the Hillsborough East River.

Although construction of the Hillsborough Dam has significantly changed the landscape, the catchment area and the reservoir still teem with wildlife. Around the reservoir area, twenty-eight (28) species of birds can be identified in the Canadian Pine trees surrounding the lake.[Read more...]
Caroni Water Treatment Plant The Caroni Water Treatment Plant (CWTP), commissioned in the year 1981. This treatment plant extracts water from the Caroni River which is then distributed via two major pipelines to North and South regions of Trinidad.
On the compound of this facility are two (2) sludge lagoons. These lagoons are used to hold the sludge derived from the treatment process from this plant. Each lagoon has an area of seven (7) acres and is approximately 10.5 feet deep.

Over time the lagoons have provided a suitable habitat for a number of species such as, Southern Lapwings, Wattled Jacanas, Plover, Herons, Egrets, Ducks, Purple Gallinules, Pied Water Tyrant, Kiskadees and Caimans. There are also a variety of fresh water fishes such as, “Guabine” and Guppies (Poecilia sp.) [Read more...]
Beetham Wastewater Treatment Plant Beetham Wastewater Treatment Plant was constructed in the early 1960's and was designed to collect and treat wastewater from the greater Port-of-Spain area and its environs.

Since the Beetham Wastewater Treatment Plant is located in the vicinity of the Laventille Swamp, different species of mangrove can be found here. The black mangrove is the most dominant species of mangrove found in this area. Patches of white mangroves are also found here, but are only on elevated parts of the forest. The other vegetations that can be found in the Laventille Swamp as well as around the sewage lagoon are described in Table 5 and Table 6 respectively. The fauna around this area are documented to be mostly birds, insects and some species of reptiles. (Table 7) [Read more...]
Edinburgh Wastewater Treatment Plant The Edinburgh Wastewater Treatment Plant was constructed by HDC (Housing Development Corporation) formally known as NHA (National Housing Authority) in 1983. It was designed solely to treat wastewater from Edinburgh 500 Housing Scheme. This facility was eventually adopted by WASA in 2004.
Located on the plant's compound are two treatment ponds. One of these ponds is an aeration pond and the other is a polishing pond. Both ponds cover a total area of 1.5 acres. This wastewater plant can found on 5th street Edinburgh, Chaguanas.
