Nashik Municipal Corporation to buy alum worth Rs 1.37 crore
An NMC official said, "The water received from the rains is dirty. We use liquid alum on a large scale to purify this water. Around 2,000 to 2,500 metric tonnes of liquid alum is required for this purpose. 2,000 metric tonnes of liquid alum will be purchased for the financial year 2013-14. It is estimated to cost Rs. 1.37 crore. The liquid alum will be procured from private firms through tender processes. An e-tender has already bee."
The NMC's proposal to buy 2,000 metric tones of liquid alum was passed at NMC's General Body Meeting held last month. Last year, the civic administration procured around 2,200 metric tonnes of liquid alum for water purification.
NMC uses liquid alum to purify water at its five water filtration plants - Bara Bungalow water filtration plant, Shivaji Nagar water filtration plant, Panchavati water filtration plant, Gandhinagar water filtration plant and Nashik road water filtration plant. Around 350 million litres (MLD) of water is supplied to the city from these five water filtration plants everyday.
