MODULE-4 WATER CONSERVATION
INTRODUCTION
Water conservation is the practice of using water
efficiently to reduce unnecessary water usage. According to Fresh Water Watch,
water conservation is important because fresh clean water is a limited
resource, as well as a costly one.
The aim of a water reservoir is to serve as a vital resource
for storing and regulating water supply, ensuring reliable access to water for
various purposes such as irrigation, drinking water, hydroelectric power
generation, and flood control. Additionally, reservoirs contribute to
environmental sustainability by supporting aquatic ecosystems and providing
recreational opportunities for the surrounding communities.
VISIT TO HARANGI RESERVOIR
Located in the Hedgers village
near Kushinagar. Har dan makes ton lasoting
visit. The dam has
been butt across the tributary of River Cauvery
and has a height of 47 maten
and length of $46
meters it is one of the popular picnic spots with a mesmerising natural setting
and relaxed atmosphere. Located at a distance of approximately 36 km Gum
Maliken, Harang dan is the fint Dam to have been built across River Cauvery
The place is comparatively len crowded and thus is perfect for those looking for
some seclusion and private time with nature Soothing environment with gentle
breeze greets as you enter the area around the darn. The best time to visit the
dam is during the months of August to September
Harangi Hydroelectric Project 9MW (2×4.5MW)
1. Catchment: The catchment
area of the Harangi River at Harangi dan site is 419 58 sq- km. (162Sqmiles).
The head reaches of the catchment area Hilly
with step valleys and forest interspread with plantation of coffee, orange
and wet land patches on the bank of
river where the average rainfall is nearly 3810 mm per annum The rainfall
gradually decreases to 1234.00mm as it approaches the dam site. The bulk of the
rainfall occurs in the months
of June to September and the river
will be in floods during
these months when almost the
entire yield is received
2. Yields The maximum and
minimum annual virgin yields at Harangi dam site is 39.3 Meft. At
dependability.
3. Storage The dam is designed
to pass a probable maximum flood of 2973.66cumecs (105000 Cusecs). The gross
storage capacity at FRL of 871.42m is 8500 Meft(8.50TMC) and a live storage of
8073 Meft. (8.073TMC) and a dead storage 427 Mcft (0.427 TMC) atMDDL of 846.734
m. The crest level is proposed to be at R.L860.755m
4. Water Spread: The reservoir
water spread submerges an area of 1900 На (4717 acres) displacing a population
of about 13 villages.
Harangi Hydroelectric Project
9MW (2×4.5MW)
EDCL owns and operates a
run-of-the-river 9 MW (2X4.5 MW) Hydroelectric Power Project at Harangi River.
The 9 MW Project was set up by the company in 1999 on the left bank of Harangi
Dam(parallel to left bank irrigation canal), District Kodagu in Karnataka State
Power Generation using existing Irrigation Dam
Harangi River is one of the major tributaries of River Cauvery
originating from Pushpagiri Hills in Kodagu District, Harangi
Dam was built in 1970s across the river near Hudgar village of Somawarpet taluk in District Kodagu
to cater to irrigation requirements of the commandarea
The Harangi
HEP was built in 1997 downstream at the toe of the Dam by EDCL
It utilizes the head between
FRL of Harangi Dam and the NWL of the left bank canal for power
generation. After generation, tail waters from this power plant are released
into the left bank irrigation canal to serve the irrigation requirements in the command area. The Harangi HEP is
our first project and exemplifies our commitment to environment-friendly and
sustainable development of energy by optimal utilization of existing
infrastructure.
