Other Measures taken in Water Conservations
Various measureare already taken and some
are in the pipeline for effective conservation of
Water. NALCO, CPP is continually putting its effort
to bring down the resource consumption by adopting
new technology and retrofitting new system in place
of old one. Some of them are
1. In order to further reduce the water requirement
in ash transportation NALCO, CPP is shifting
towards dry evacuation of ash from the present wet
type and already installed have taken the dry system
in their Unit no-7 & 8. For Unit 1 to 6 dry disposals
road map prepared and will be completed by 2011.
Efforts are being taken to use the ash as cash, by
selling it to cement plants and other end users.
2. In the future project of Unit-9 & 10, NALCO,
CPP is going for high concentration slurry disposal
system (HCSD) to the ash pond where the water
requirement will be substantially reduced.

3. MAGALDI bottom ash disposal will be done
for the forthcoming units no-9 & 10.
4. In the present system for transportation of ash
slurry from ESP, hydro sluicing system is provided.
Jet cone measurement and quick action for replacing
the defecting jets are done so as to optimize the water
requirement in that area.
Conclusion :
Well designed measures, therefore have saved
CPP, NALCO to conserve water to the tune of 3100
M 3 /hr thus reducing the intake water flow from 7000
to 3900 M 3 /hr. Apart from conserving this natural
resources it also helps us directly to save energy
which otherwise is required to pump from river
Brahmani. The bountiful gift of nature in this part
of the world notwithstanding, NALCONIANS
understand life without water & therefore take all
possible recourses to optimize the use of this
precious gift of nature- Water.
