When we visited the town of Bekasi then we will see a river that runs in
the middle of the city of Bekasi. River length of Purwakarta Jatiluhur to the
area of East Jakarta, Kalimalang river its name. The road along the time
makes a very strategic area for residential and even commercial. Kalimalang
itself actually is not the time or the nature of the river, but a man-made
time, which aims to supply clean water from the reservoir. Since that time the
water quality in the area of Bekasi to Jakarta is not suitable for
consumption. Then, why is called Kalimalang? Average time nature in West Java
was always flows from South to North or North to South, because the coast of
West Java in the north and the south. But Kalimalang river from east to west
and transversely between existing natural time. Kalimalang made with natural
position above the river that flows from South to North. Can be seen in the
area Cipinang Melayu, Kalimalang position is above the position of crossing
times Sunter Sunter Kalimalang toward the North and to the West. Kalimalang
which has a length of 20 km, from Cawang (Jakarta) to Bekasi, village or region
that covers along the river is New Cawang - Cipinang Melayu - Pondok Bambu -
Coconut Cottage - Lampiri - Sources Arta - Transito - Jaka Permai - galaxy -
Earth Dating Satria, Bekasi and Metropolitan Mall continues until the Bekasi
area.
Kalimalang River watershed is derived from Jatiluhur dam in Purwakarta is
essentially used to supply water to the Water Company (PAM). In addition to
irrigate agricultural areas, the flow of the river flowing past Kalimalang some
areas which eventually empties into the sea is also used by the surrounding
communities as a means of domestic interests such as washing, bathing, to
dispose of human waste. Habits of the people who are always taking out the
trash, and defecating coupled with other activities such as bathing children
make Kalimalang become unhygienic water again. Though Kalimalang water is a
source of raw water for the water needs of the majority of the river’s flow
into the territory of East Jakarta and Bekasi area. Coupled with the presence
of a mound of rubbish on the edge this time resulted in complete already
Kalimalang river water pollution problems. The pollution of the river water is
usually brownish Kalimalang, suddenly turned into a solid black and oily.
The water in the channel Kalimalang obviously been contaminated waste even
there is also a result of chemical waste polluted river banks made a lot of
shelter thrift. E-coli contamination levels there ranged from 80,000 to 100,000
MPN per 100 miles of water. Though e-coli threshold for raw materials clean
water only Rp. 1,000 MPN/100 miles of water. But as has been said that the next
Mayor of Bekasi will be held jobs related to flood management in Bekasi. One of
them is the development pengerjaaan Sifon Kalimalang the budget using state
budget funds as well as funds from the Asian Development Bank (ADB). WTC
irrigation canal that divides the city of Bekasi, the river flow will be
resting around the weir Bekasi, Bekasi. From Bekasi Weir, Water Kalimalang
already united with water piped times Bekasi west to Jakarta. In addition to
maintaining the quality of raw water from Jatiluhur, irrigation channel
separation with time Bekasi WTC can also minimize flooding to urban areas.
Imperative in planning the construction of culverts required careful technical
planning. In accordance with Law no. 11 1971 on irrigation in chapter 8 says
that the arrangements for water and irrigation system as well as the
construction of water prepared on the basis of planning and technical planning
in the public interest.
Apparently, Public understanding of the importance of preserving the
environment seems to be still lacking. Evidenced by the many buildings
constructed defecation along the river. While in addition to this, a variety of
activities that lead to environmental pollution seems with the advent of junk
collectors who cleans junk former mill waste containing chemicals. Including
second-hand goods that have been ragged and certainly pollute streams. In fact,
the water in the river WTC as a feedstock for clean water for people in Jakarta
including the City and Bekasi. The level of contamination in the raw water
content in the Kalimalang river will increase. Therefore, the role of local
governments plays an important role to minimize and even eliminate pollution of
streams. But until now, Kalimalang into rivers that supply water from the
reservoir. The river never dry season despite drought came. Uniquely, each of
our Independence Day Celebration, this Kalimalang river into a party of the
people to hold a traditional competitions.
