Problem Statement and significance
Georgetown, the capital of Guyana, is located at the mouth of the Demerara River and North of
the Atlantic Ocean. Flooding is a major problem in Georgetown. The city is a major hub for
commercial activities, schools and other infrastructures. Whenever flooding occurs in the city,
this result in loss of income for businesses and the daily routine of the education sector is
interrupted.

According to data recorded from the Ministry of Agriculture Hydrometerological Services, when
Georgetown receives a minimum rainfall of 4.1mm, it is flooded; for example in 2008;
Georgetown received a maximum of 3365.2 mm of rainfall. The existing canals and drainage
system cannot accommodate this large volume of water nor poor solid waste disposal
management, which clogs up drains and causes an increase in flooding .
Flooding in the city has a tremendous effect on the residents and civilians since it causes a
setback on the regular schedules of the participants in that area. It was noted that on
December 17th, 2013 the compound of the Saint Stanislaus College was submerged
Figure 1.0
along with the roadways and other high schools, businesses and market vendors as shown in
figure 1.0, therefore resulting in a number of crisis such as the loss of stored goods, damage to
electrical appliances, the outbreak of leptospirosis along with the absentia of students, teachers
and other business personnel.
Excess rainfall and sea level rise are two of the most prevalent climate changes and as a result,
flooding will continue to affect the habitat of the mentioned region if a proper drainage system
is not implemented. According to the fourth assessment Report of the Intergovernmental Panel
on climate change (2007), global sea level have risen by approximately 1.5 mm per year,
between 1961 and 2003 and by 3.1 mm per year between 1993 and 2003. Guyana’ annual
rainfall prior to 1960 is a relative sea level rise of 10.2mm per year and the average rainfall is
225 mm per year.
Objectives of the Project

To convince engineers and other stakeholders that the project is more efficient and
economical.

To allow society members and school attendants to carry out their daily tasks even
when it is raining heavily.

To minimize the risk of flooding.

To show the viability of the project.
Proposed Solution
In Guyana our population is being confined to modern day living, hence the demand for house
lots have to increase. So the government sought it good to abolish the cane fields and create
house lots and housing schemes; on the population’s behalf it is a good idea but on the climatic
behalf it is detrimental to the coastland residents. Since the cane fields had to be converted to
housing schemes and the land and canals were filled up, culverts had to be removed thus
leaving no path and exit for drainage when there is heavy and continuous rainfall. Therefore, as
a result the remaining drains in the town sites have to accommodate large volumes of water to
exit or dump into other larger drains, then into the river.
With this being observed, the researcher has come up with a plan to solve this situation which
is basically the modification of the Georgetown’s water pump system;
The main function of the pump is to keep the water level in the drain at a minimum level of
25% of the total drain height. The pump is designed to discharge the water in the river when
there is Heavy Rainfall. When there is enormous rainfall during high tide, the koker doors
would have to be closed because pumping this large volume of water will put the pump under
tremendous pressure. When the pump is not in operation, there is an amber light on the panel
indicating that the pump is at rest. The float switch sensor is responsible for activating the
engine start relay; it is installed in the drain to relate the signal to the control panel where the
water level is at. As long as the water is at its minimum level (25%) the pump will not be
activated because the float switch is in its open position. When the water level begins to raise
in the drain the float is being carried upwards by the water and closes the switch at a maximum
height of 75% of the drain height. When the switch is closed it completes the relay coil circuit in
the control panel, shuts off the amber light and turns on the green light; the green light
symbolizes that the pump is in operation.
When the relay coil is closed, it transfers the source power (12 volts D.C) to the starter motor,
henceforth starting the engine and putting the pump in operation. The pump therefore will
discharge the water through the discharge pipe into the sea until the water level starts
decreasing. As the water decreases the float moves downward to its minimum level re-opening
the float switch and deactivating the pump once again.
This system can be implemented in schools and communities which experiences flooding. The
pump will be installed in the schools and community by placing the suction section into the
main drain and discharging it through large pipe lines into the sea. In areas located far from the
sea, the water can be discharged into the closest canal and then into the sea with the
inspection of these canals to be free from blockage of any materials. It must be noted that
pump size varies according to volume of water recorded in different areas. For example, in
schools a 4 inch pump is more likely to be used because of the small drain size whereas a 6 inch
pump will operate better in a community.
The Competition
The project proposed was already attempted by others, however due to the Automatic system
designed, it is much more preferable to use rather than the manual system that was already
implemented by others.. Individuals would rather a pump system that can operate on its own.
