People in communities across Trinidad, attempting to rebuild their lives in the aftermath of last week’s flooding, remain stunned by the deluge and destruction and are now questioning whether the Government is doing enough to mitigate the impact of flooding in the country.
While hundreds of millions of dollars have been spent over several years in an attempt to mitigate flooding–through studies and some infrastructural work–thousands of people in central and south Trinidad, as well as areas along the East-West corridor, are yet to see the full effects of those flood relief plans.
Approximately $636.6 million was spent between fiscal years 2018 to 2022 on attempts to improve drainage infrastructure and reduce the impact of flooding, according to Public Sector Investment Programmes documents. But not even this large amount spent could help stop the catastrophic deluge.
In fiscal 2022 alone, $130.6 million was spent.
Here is a breakdown of how the money was spent for some of the major projects:
*Of that figure, $3 million was expended on the advancement of projects under the Programme of Upgrade to Existing Drainage Pumps and Gate Inventory.
*The Tulsa Trace (Penal) pump house/gate structure was advanced to 95 per cent completion, gate structures in St Augustine to 25 per cent completion, and gate structures at Trinidad Point in Woodland to 80 per cent completion, while tender documents for the upgrade of gates at Bamboo No 2 were completed and awarded.
*Another $1.5 million was spent to advance the Major River Clearing Programme for the Caroni River Improvement Project to 90 per cent completion, while three pumps were purchased to help mitigate the impact of flooding on properties located along the Caroni River.
*$6.3 million was spent on flood mitigation measures through the Management and Flood Control (Orange Grove Food Crop Project) aimed at providing water management interventions to enable sustainable farming in selected project areas, as well as the Rehabilitation and Development of Physical Infrastructure at Plum Mitan.
*In addition, $2 million was allocated to purchase and install two new sluice gates to control the flow of water at the Plum Mitan Project.
The amount spent on projects listed was $13 million, and some of these still remain incomplete.
Comparatively, in fiscal 2018, $133.1 million was spent; in fiscal 2019, $143.4 million; and in fiscal 2020, $223.9 million. In fiscal 2021, $5.6 million was spent, according to the PSIP 2022 document.

100 years since T&T did any major drainage works
But despite the millions allocated and spent, it has been about 100 years since the country did any major drainage works, according to civil engineer and President of the Joint Consultative Council (JCC) for the Construction Industry Fazir Khan.
He said an example of the failure to upgrade was the fact that the dry rivers in Port-of-Spain were paved many decades ago and nothing has been done since.
While global warming is a contributing factor to the flooding, Khan claimed that it only accounts for ten to 20 per cent of the increase, with other factors such as development, drainage, legislative, administrative, and infrastructure issues accounting for the rest.
Even though there were many studies done, there would not have been a commitment to implementing or making investments into the infrastructure, Khan added. "This is not just today. The development wasn’t commensurate with the development of the systems and the infrastructure wasn’t commensurate with the development of the land and the increase in population and so forth."
Khan lamented that while millions have been spent on flood mitigation studies by successive governments, there has been minimal implementation.
“There are many studies done by many different people and I think the Government needs to review all these documents, and get serious about an implementation plan. The capital investment would be significant, but it’s not something we can fix in a very short time, but we have to have a working plan moving forward,” he said.
Flood/drainage studies conducted by governments between 2012 and early 2019 cost $66 million, according to engineer Deoroop Temal, chairman of the Joint Select Committee on Land and Physical Infrastructure on an Inquiry into Flood Alleviation and Control Measures for Major River Basins and Drainage Catchments in T&T.
Among the studies conducted were the North Oropouche River Basin Study by the IBI Group in 2008; the Feasibility Studies and Detailed Design for Ortoire River Basin Drainage Study by Lee Young and Partners in 2009; the Caroni River Basin Study by Royal Haskoning Caribbean in 2011; the Caparo River Basin Study by Royal Haskoning OHV/Haskoning Caribbean in 2012; as well as the Feasibility Studies and Detailed Design Consultancy Services for South Oropouche River Basin done by Royal Haskoning DHV/Haskoning Caribbean in 2012.
The Sunday Guardian was not able to get access to these studies, however.
Last week, businessman Ishan Ishmael called on the Ministry of Works to disclose a series of official reports on flooding in the Bamboo, and he has instructed his lawyer to make a request under the Freedom of Information Act for the information.

3 years after Sinanan's claim, questions about Govt's operational plan and its effectiveness
In 2019, when announcing another flood study, Works and Transport Minister Rohan Sinanan admitted that the State had spent large sums of money on drainage plans and studies.
“We spend a significant amount of money doing studies and we never implement anything. What we are trying to do now is take all these studies, create one national study and create an operational plan going forward…Every year we just keep going out there and handing out cheques and we just can’t continue like that,” Sinanan said in 2019.
Three years later, there are questions about the operational plan that Sinanan spoke about and its effectiveness.
The National Drainage Plan
In 2020, the Development Bank for Latin America (CAF), as part of the T&T Government’s attempt to prepare a national drainage plan, selected Dutch urban development consultancy and engineering bureau Witteveen+Bos, as well as local partners Trintoplan and Ecoengineering to prepare a final design of measures against flooding.
According to Witteveen+Bos’ website, the project started in February 2021.
Witteveen+Bos said that a strategic drainage plan, an economic analysis, as well as a set of short-term and long-term measures for each river basin present in the plan were completed by August 2021.
In 2022, according to the dutch engineering consultancy bureau, they were expected to make designs for drainage measures that could be “applied immediately”.
“These are improving embankments, upgrading drains and a pumping station; dredging, hydrological check; and establishing a frame of reference for more detailed surveys and studies.
“The implementation of these measures is the first step towards an improved drainage system, but short and medium-term measures are also needed to limit the consequences of flooding,” the dutch company said.
Earlier this week, the Sunday Guardian wrote the communications department of Witteveen+Bos seeking further updates about the project.
However, this was their response: “Thank you for reaching out to us, we appreciate the opportunity. In this case, however, we have to refer you to the T&T Ministry of Works and Transport, through the Permanent Secretary for more information.”
On Monday, the Sunday Guardian spoke with Sinanan, seeking an update about the national drainage plan.
He said he addressed the subject earlier in the day at a press conference.
We asked him if the five-year timeline that he gave in May 2020 for the national drainage programme to possibly eradicate the financial burden of flooding was still achievable.
“Well, it’s an ongoing programme that we have started and as weather patterns change, we will keep upgrading the programme. So, yes. Things are on the way,” he said.
At Monday's press conference, Sinanan said that the plan was ongoing.
“Our main plan is to move this water...once it gets into the major water course and so, how we move the water out. Yes, there’s an element with Town and Country, with the local government authorities and so, to make sure that the localised surface water and the infrastructure for that are improved to a certain code and a certain standard,” he said.
In June 2020, the Development Bank of Latin America (CAF) requested bids for a consultancy service to prepare the final design of immediate measures for flood control and a drainage action plan in T&T.
The bid, according to CAF, was put out at the request of the Government of Trinidad and Tobago, with the Andean Development Bank financing the consultancy services at an expected cost of US$450,000.
In the bid, a detailed work plan for every major river basin in Trinidad to mitigate flooding was outlined.
No approximate costs were given.
*According to the bid request, the Caroni River Basin required embankments to protect the critical flooded towns, a swamp inlet regulator, dredging of the estuary, an upgrade of remaining pump sites in the catchment, detention dams which have the most flood reduction impact with the least land acquisition, improvement works on the Malick River, as well as silt traps in recommended areas.
*The North Oropouche River Basin required an upgrade of the drainage system in the vicinity of Genda Road, an upgrade of the channel from Shivan Road to the river outlet, channel improvement works to the tributary to Guaico River, an upgrade to the Bamboo river channel, upper watershed management/stormwater management of Bamboo river, as well as the replacement of crossings and culverts where channel upgrades were undertaken.
*The South Oropouche River Basin required improvement works on the Coara River and associated access, embankment reconstruction works on new cut channels and tributaries, and a flexible flood barrier system where feasible.
*And the Ortoire River Basin required a flexible flood barrier system and a replacement of underperforming structures, such as culverts and bridges.

Repeated recommendations by experts
Over the past week, the Sunday Guardian’s research of available studies found that most of the issues that likely cause or exacerbate flooding have been identified, with many recommendations repeated in the studies. Most of them have not been implemented.
In June 2020, the 10th Report of the Joint Select Committee on Land and Physical Infrastructure on an Inquiry into Flood Alleviation and Control Measures for Major River Basins and Drainage Catchments in Trinidad and Tobago Subjected to Major Flooding over the Past Few Years was laid in Parliament.
Among its more than one hundred findings, the report found that the Planning and Facilitation of Development Act do not sufficiently treat flooding; Flood Management legislation needs to include high penalties for breaches and adequate resources for enforcement; Drainage infrastructure in T&T is generally aged and is not sized to accommodate current rainfall patterns.
Also, frequent siltation is occurring because of poor land use practices; the Ministry of Works and Transport received insufficient funding in fiscal 2019 to upgrade and replace pumps and gates; There is a need to treat with deforestation given that it leads to soil erosion.
In addition, developers engage in developments with little inspection by the Municipal Corporations; and activities such as illegal quarrying, encroachment of river reserves, backfilling and illegal diversion of watercourses are challenges.
In the summary of the report’s recommendations, it was proposed that firstly, a comprehensive flood management act to incorporate all the various responsibilities for flood management should be enacted. And secondly, adequate funding should be allocated under the PSIP for the upgrade of existing drainage pumps and gates and that budget cuts should not be made from this priority item.
*In 2019, the United Nations Economic Commission for Latin America and the Caribbean (ECLAC) published an economic analysis of flooding in the Caribbean.
The report referenced findings of government-commissioned studies not available to the public.
“Flooding as other types of hydro-meteorological events have been exacerbated by developmental change and urbanisation patterns. Loss of protective vegetation caused by bushfires, indiscriminate clearing, and degradation of forests for housing and urban development are key drivers. Combined with agricultural practices, such as cultivation on steep slopes, slash and burn, and poor watershed management.
“These all contribute to soil erosion and increased sediment yields in rivers and canals that cause changes in the distribution of the total basin runoff over peak flows and baseflows,” the report found.
The ECLAC report said the development of new urban and agricultural areas has often not been accompanied by the expansion of appropriate infrastructure, especially drainage systems.
“Moreover, the urban development has progressively sprawled northwards and upslope into several valleys in the southern flank of the Northern Range, areas considered critical for soil and water conservation,” it said.
*In March 2001, a national report on Integrating the Management of Watersheds and Coastal Areas in Trinidad and Tobago by the Water Resources Agency found that while a sizeable sector of T&T’s economy depends on income generated by the agricultural and quarrying sectors, the practices have resulted in the wide-scale degradation of many watersheds within Trinidad and Tobago.
“The general consensus is that the hydrological response of rivers to rainfall has changed over the years due to such degradation…Higher sediment yields led to an increase in the cost of drinking water production and more regular maintenance of water treatment plants, together with increased incidences of flooding in areas along the east-west corridor and the Caroni Basin.
“The Caroni Basin is already under threat from poor land use practices, including the deforestation of the Northern Range, which results in perennial flooding in the lower regions of the Basin,” the report found.
The report also stated that alleviating flooding in the flood plains of the larger rivers such as Caparo, Caroni, South Oropouche, and North Oropouche called for substantial capital investments.
“There is generally an increasing concern about an apparent inability of the public authorities to institute satisfactory measures of flood control based on drainage engineering designs,” the national report by the Water Resources Agency found.
*In March 2003, the National Emergency Management Agency’s National Flood Contingency Plan found that proper zoning systems and the enforcement of land-use regulations were critical to water and flood management.
It said that various sub-plans ought to be developed to minimise the likelihood of flooding.
1. The first sub-plan was erosion control and runoff reduction methods.
The proposed methods included forest conservation and reforestation, preventing/minimising undesirable land clearing, promoting change in agricultural techniques, slope stabilisation, as well as regulation of post-development flaws as per design criteria and drainage requirements.
2. The second sub-plan involved coastal methods.
The proposed methods included beach and wetland preservation, seawall and dyke construction, construction of other near-shore and coastal protection mechanisms, wetland and reef preservation, as well as monitoring and maintenance of near-shore marine ecosystem health.
3. The third sub-plan was to reduce velocity flows.
The proposed methods included energy dissipators in high-velocity streams e.g detention ponds and hydraulic drops; as well as retention systems e.g construction and maintenance of dams.
4. The fourth sub-plan was flood control.
The proposed methods included maintenance of water courses, sea walls, sluice gates, and dams; capacity improvements eg paving, widening, and alignment of channels; mobile pumps for depressions and low-lying areas; permanent pumps in critical low-lying areas; as well as dykes and embankments.
Other proposed methods were flood-warning systems, public alerting systems, evacuation, relocation of high-risk communities, and the development of flood hazard maps.
We need to act now
According to Kegan Farrick, a lecturer at the Geography department at the University of the West Indies St Augustine Campus, with the growing threat of global warming, T&T is looking at the potential of more serious floods given projections of increased rainfall and heavier rains over prolonged periods.
He said that given this possibility, it is important that the country manages flooding factors under its control, like monitoring poor or illegal planning.
“There are tons of developments in a lot of hillside areas…and mountains and hillsides are natural stores of this type of rainfall, so what you see is when you pave those areas or you change how the water makes it down to the rivers and streams, you are reducing the capacity. It’s like a buffer. Those things will buffer and reduce how much water is coming down quickly.
“I think there’s limited capacity as well, as with many things…When we are looking at environmental issues, we have all the rules and regulations in place, but it’s the enforcement and the human power to be able to go out and monitor development to ensure it’s being done the correct way,” the former head of UWI’s geography department said.
In September 2020, former Planning and Development minister Camille Robinson-Regis said land developers whose projects worsen flooding and destroy natural habits could face the law.
“As Minister of Planning and Development, the Environmental Management Authority and the Town and County Planning Division, under my remit, are investigating a number of land developments being undertaken in various parts of the country, to guarantee that the responsible developers have the obligatory approvals and are meeting the necessary legal requirements.
“If it is discovered that none of the above has been met, then all actions available to the Ministry under the law will be implemented to either stop the developments or to ensure that the proper measures are being undertaken to safeguard the natural environment of Trinidad and Tobago,” she said in 2020.
In 2021, the former Planning and Development Minister claimed, once again, that environmental laws would be increasingly enforced to help manage flooding.
She said there must be a balance between proper use of the environment and expanding development.
“Legislation exists to regulate use and care of our environment and reinforcement will be enhanced to deal with flooding issues. Some of the regulations that will begin to be reinforced through the Environmental Management Authority (EMA) include the Water Pollution Rules, 2019 and the Water Pollution (Fees) Regulations, 2019, the Waste Management Rules, 2021 and the Waste Management (Fees) Regulations, 2021,” she said.
From enforcing environmental laws, Farrick said it was also important that homes and communities are adapted to deal with the changes associated with global warming.
Examples of physical adaptations, he said, were improving drainage systems, constructing homes on stilts, or making adjustments to the locations of major roadways.
“We have several different types of solutions that we can use. Right now, what’s becoming popular are these nature-based solutions where we build with nature and we utilise some of the natural structures in place. So trying to restore wetlands, for instance, because wetlands help with flooding. They store and retain a lot of water…We’ve lost a lot of those wetland areas in the country using things like more permeable pavements.
“We can make the correct adaptations. So if we have the correct planning and proper governance, for instance, then we can put all the things in place to reduce these sorts of impacts long term,” he said.
