All of the above
photos show a depiction different drainage systems in urban cities in Trinidad.
The first photo was taken in an area in Tunapuna. This picture showed the lack of
proper infrastructure to cope with an intense rainfall event. The drain
contains a limited amount of water that is stagnant as well as a green
substance. The green substance was a chemical improperly disposed of into the
drain by someone. This chemical may have gotten their as a result of runoff by
an industry. As the chemical is unknown it may be hazardous to human and animal
health.
The second photo was
taken on the bus route at UWI St Augustine. The photograph showed a drain
containing concrete and stones that were broken off of the culvert as well as
other debris that made its way into the drain. This drain has been at this deplorable
condition for quite a long while as I first noticed it upon entering UWI and
currently I’m in 2nd year. This showed that no one was responsible
for monitoring and maintaining the drainage systems in Trinidad.
The final picture
displayed an image of a man-made river or a drain in Belmont during the dry
season. As can be seen the river is not maintained and cleared to prevent
flooding. The river contained several patches of grass as well as numerous
debris which probably arrived as a result of surface runoff into the river. Upon
questioning a resident of the area I was told that when an intense rainfall
event occurs the river is unable to hold all the water and flooding occurs as a
result.
As seen in all the
photos, the drainage system is very inefficient and needs to be upgraded and
cleaned regularly as flooding is one of the impacts of polluted drains. The links below show how serious flooding can affect the urban city of Port of Spain. Due to the poor drainage systems and the problem of pollution in P.O.S. a short intense rainfall event leads to the severe flooding of the city.
