dc.description.abstract | Background
The non-technical summary outlines the findings of the Environmental Impact Assessment of
the relocation of sewer outfalls near Indira Gandhi Memorial Hospital and West Park Area of
Male’. The outfalls are planned to be relocated to the industrial village area of Male’. The
proponent of this project is Male’ Water and Sewerage Company Pvt Ltd. The total estimated cost
of the project is MRF 10 million.
The project involves relocation of the outfalls for the Pump Stations PS5 and PS6 which were
located near West Park and the outfalls for Pump Stations PS3 and PS4 which were located near
IGMH. The pipes from PS3, PS4, PS5 and PS6 will be re-routed to the four new Pumping Stations
at the MWSC plot at Male’ Industrial Village (on the southern side of Male’). The proposed sea
outfall is from these stations to the the southern side ocean.
Key impacts, mitigation measures and al ternatives
Impacts on the environment from various activities of the project development work
(constructional impacts) and operational impacts have been identified through interviews with the
project management team, field data collection and surveys and are also based on past experience
of consultant in similar projects. Impacts were analysed for their significance with the aid of a
Leopold Matrix.
In any development project, major direct impacts to the environment occur mainly during the
construction phase. Potential direct or indirect impacts on the environment from the proposed
project include:
Minor to moderate impact on groundwater due to dewatering required during trenching
works for rerouting of pipelines;
Impact to marine habitat due to physical damage to live coral due to trampling during
pipe laying works;
Minor impact due to air and noise pollution during construction work
Impact on traffic flow and road use
Minor impact on marine environment due to sewage disposal
Mitigation measures are discussed for the activities which would have potential impacts during
the construction and operational phase of the project. In general, during the construction stage it is
important to use a method of construction which has the least impact on the environment. Specific
x
measures highlighted include following of established guidelines when carrying out excavation
works and dewatering. Detailed mitigation measures are discussed in Section 11 of the report.
Alternatives have been considered for various components of the project and are given as
possible options that may be either more practical or less expensive to the preferred options. The
proposed alternatives also have taken into consideration the environmental consequences resulting
from these options as compared to the preferred options. The following components of the project
have been discussed in providing these alternatives:-
Outfall pipeline arrangement
Outfall pipeline routing options
The no-project scenario is also considered, which would mean that all environmental impacts
due to the project would no longer be an issue. However, this also means that the current issue of
sewage pollution of the lagoon of the western side of Male’area, namely the Rasfannu swimming
area, will have the chance of being polluted with sewage, thus effecting the health and well-being
of the recreational swimmers and beachgoers.
The environmental impacts predicted for the project are primarily minor to moderate, hence the
benefits of continuing the project, though with a cost to the environment, is seen to be far more
beneficial than the cancellation of the project; as the health risks faced by the large number of
population using the Rasfannu area is not something that should or can be overlooked. Therefore,
the “no-project” scenario is not a feasible solution and it is recommended that the project be
continued, but with the proper implementation of all mitigation measures proposed in the report.
Details of the various alternatives considered and the selected alternatives are shown in Section
of the report. | en_US |
