Plan for flood management approach on Trinidad

The Corporación Andina de Fomento (CAF Development Bank of Latin America) has tasked Witteveen+Bos, together with local partners Trintoplan and Ecoengineering, with preparing the definitive design for measures against flooding on Trinidad.

This island of Trinidad experiences significant flooding during heavy rainfall. On 18 and 19 October 2018, heavy rain caused serious flooding and related damage on Trinidad and Tobago, affecting around 80 per cent of the country.

In 2019, Witteveen+Bos was involved in a quick scan for the rebuilding and improvement of Trinidad’s drainage. In order to implement the suggested improvements, the Ministry of Works and Transport elected to develop a plan to improve the drainage system and prevent flooding.

Witteveen+Bos will now take the first step and, together with the local partners, create a strategic plan for identifying both short- and long-term measures for the various catchment areas.

The issue of flooding is not being approached as a purely technical challenge: the involvement of stakeholders and the integration all affected sectors are important elements in our approach. A set of short- and long-term measures for each catchment area will be included in the strategic plan.

The second step will involve creating a definitive design for the chosen measures, following which tender documents will be drawn up. The entire project will run until the start of 2022, with the strategic plan being realised in June 2021.
