Dear All,
IUWASH
(Indonesia Urban Water Sanitation and Hygiene) Program is the program
for Water, Sanitation and Hygiene of Indonesia Urban which lasted for
five years, which has the term for five years, funded by the US Agency
for International Development (USAID). IUWASH makes the effort to assist
the Government of Indonesia to make a progress to reach the Millennium
Development Goals by expanding the access to clean water and safe
sanitation services. Developing the access to water and sanitation
services for the poor Indonesian urban, especially those having very
limited access to such services is the IUWASH main goal. The expected
results are: (a) Two million people living in urban areas have access to
safe drinking water services; (b) 250,000 people living in urban areas
have access to adequate sanitation; and (c) the cost of water per unit
borne by low-income people is decreased at least 20%.
Based
on the results of the study and general analysis has been done by
IUWASH on all PDAMs are becoming partners IUWASH shows, that the entire
resources of raw water PDAMs have experienced a serious decrease in
discharge and quality of raw water resources, so if no protection
measures and prevention are done , then PDAMs can not provide water
service to its customers in the future. Problems of discharge reduction
and quality of water resources will increase by climate change events
including rainfall patterns that will be shorter with high rainfall
intensity (heavy rain or storms) and the incidence of drought are
getting longer and more dry. As a result of a combination of changes in
land use and climate change in the form of rainfall intensity, it will
affect stability of the slopes and land which can lead to the occurrence
of landslides which may damage key infrastructure, including raw water distribution facilities.
Total
processing capacity of PDAM Kab Bandung is currently 740 L / s (with
76% utilized), of which the sources are surface water 80%, springs 12%
and shallow wells 8%. One of the major constraints faced by PDAM Kab
Bandung to provide clean water services to the community is the
availability and continuity aspects of proper raw water supply to be
treated. One of the recommendations of the CCVA study conducted by
IUWASH is the long-term adaptation by optimizing the utilization of
surface water as raw water and evaluation on high-risk infrastructure.
The construction of a pre-sedimentation basin in Nagrak intake will
provide a solution in addressing the existing problems, namely the
service continuity. This activity is relation with IUWASH outcomes
HR-1 (Increased access to safe water supply) and IC-4 (local government
institutions implementing climate change adaptation measures).
I. TECHNICAL DATA OF NAGRAK INTAKE
Nagrak
intake is one of the raw water sources used by PDAM Kab Bandung to
provide water services to the Bandung surrounding area. Geographically
Nagrak intake is situated at 07o06'81.41" S and 107o55'17.45" E, and
administratively it is situated in Nagrak Village in sub-watershed of
Cisangkuy. According to its topography, most areas of sub-watershed of
Cisangkuy, Kab Bandung is mountainous or hilly areas with the altitude
vary from 630 to 2,602 meters above sea level. Geologically, the area of
sub-watershed of Cisangkuy Kab Bandung, is Alluvial and Colluvial
sediments, a lump of igneous rock, sandstone and tuffaceous clay;
Fluvial Sand sediment, consists of combination of volcanic breccia and
tufa; Kosambi Formation, is a lake sediment which its rocks consist of
tuffaceous clay, tuffaceous silt and tuffaceous gravel; Cikidang
formation, is dominated by sandy tuff consisting of melted basalt lava,
volcanic conglomerate, coarse tuffs and volcanic breccias;
II. OBJECTIVE
To relocate Nagrak intake through pump and generators housing renovation by a contractor determined through open bidding.
For
the above mentioned purpose, we would like to invite potential bidders
to submit proposal, detail Scope of Work (SoW) etc, please see :
Thank you very much for your kind attention
Sincerely yours,
Procurement IUWASH
