The city’s growing water needs, both for domestic and industrial supply, are making the authorities look at alternative sources as well as improvements to the existing supply systems.
At a recent meeting with officials in the city, Union Minister for Urban Development M. Venkaiah Naidu expressed the view that desalination plants are the ultimate solution for the increasing water needs and asked officials to plan for them.
Best example
Tamil Nadu is seen as the best example where two desalination plants are set up at Minjur and Nemmili. While 1 KL of water at the first plant costs Rs.50, at the Nemmili plant it costs a mere Rs.21 owing to the latest technology used, it is learnt.
It is estimated that 100 mld desalination plant costs Rs.800 crore and the city needs two such plants.
GVMC has readied a detailed project report by APITCO to set up a 10 mld pilot project at Poodimadaka. AP Industrial Infrastructure Corporation has earmarked 150 acres of land for desalination plants.
The pilot plant requires 10 acres of land and the cost of the plant is estimated at Rs.80 crore. Proposals for expression of interest are readied.
The APIIC board has to approve the proposal to allot land and give a formal letter to GVMC to enable it call for Expression of Interest.
“Since the pilot project is of a modest nature, we intend to take on board major industrial stakeholders like Steel Plant and NTPC in the public-private partnership,” a senior official has told The Hindu.
The Andhra Pradesh government has also indicated that plans for a 100 mld plant should be actively pursued.
With industry hard-pressed for water, the desalinated water from the pilot project at a competitive price using latest technology will be a win-win situation. Presently, GVMC charges Rs.36 a KL from industry and for bulk supply.
As of now, it supplies 48 mgd to the domestic sector and 16 mgd to industry and bulk water supply. By 2020, it is expected to go up by 96.8 mgd with industry accounting for 20 mgd and by 2040 to 146 mgd with industry share at 30 mgd.
On the other hand, GVMC provides water at Rs.4 a KL to below poverty line (BPL) families and at Rs.8 to above poverty line families. If desalinated water is supplied to the industry, it can use the water saved for domestic needs.
