Environment Management
Plan and Water Quality
Environmental Management Plan
E
nvironmental
Management Plan
(EMP) aims to develop
a framework for
incorporating the mitigation measures
in the project cycle and monitoring of
the environmental performance. The
EMP is expected not only to reduce
the negative environmental impacts
both due to the project components
and caused by exogenous factors on
the services delivered by the project
but also helps to enhance the
environmental benefits of the project.
The environmental protections such as
source protections, surface drainage
improvement, protection of pipeline,
fencing works and overflow and waste
water management are most common
works proposed at the scheme levels.
Environmental Management Plan of
the scheme is prepared during the
development phase which is further
incorporated in design and estimate of the
scheme and implemented accordingly
during implementation phase.
The Board has been contributing for
catchments protection and drainage
improvement works under EMP in
Batch-V, Batch-VI and Batch-VII.
In this connection, water quality test
of Batch V implemented schemes are
completed and the test reports have
been already sent to the respective
communities through SOs. The test
results of Water Quality of Batch V
have been discussed and shared
among the concerned staffs of the
Board. The concerned SOs are also
being formally informed to go to the
communities to aware them for any
pollution risks that Batch V water
quality test (Implementation) results
have shown and suggest them to take
measures like source protection,
pipeline leakage control and
appropriate water treatment in
household level like boiling, sodis,
filtration, use of water guard and/or
use of water purifying substances like
Piyus and Nirmal Chakki.
The water quality tests of Batch VI
implementation phase schemes are
being carried out by water labs in the
field. The required protection
measures from water quality aspects
have been already applied in the
design of Batch VI schemes. Similarly,
the water quality test results of Batch
VII development phase are being
received and being taken care in the
design of Batch VII schemes.
Moreover, the standard formats of
community water quality monitoring
have been sent to the Batch V
communities and 48 filled-up formats
have been already received at the
Board with Batch V post
implementation phase reporting.
The Board has carried out water
quality test of 333 schemes of Batch-
V with 427 samples at the proposed
sources in the Development Phase
and it has been done in three major
categories: sanitary inspection;
physical/chemical parameters and
bacteriological test.
Results of the water quality test of
333 schemes of Batch-V with 427
samples have been summarized in
4 categories: no risk; less risk;
medium risk; and high risk. Only 1%
sources are found to be of
considerable risk through sanitary
inspection and physical/chemical
parameters test results.
Water Quality Test
and Improvement
The Board has been carrying out
water quality test of the proposed
water sources to ensure the quality
of drinking water supply. The water
quality test of the proposed sources
is conducted during Pre-feasibility,
Development Phase as well as after
implementation of the scheme.
