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.
