Waste Water Treatment By Vishvaraj Infrastructure

Waste water treatment is a process used to
convert wastewater - which is water no longer
needed or suitable for its most recent use - into
an effluent that can be either returned to the
water cycle with minimal environmental issues or
reused. The latter is called water reclamation
and implies avoidance of disposal by use of
treated wastewater effluent for various purposes.
Treatment means removing impurities from water
being treated and some methods of treatment are
applicable to both water and wastewater.

The physical infrastructure used for wastewater
treatment is called a "wastewater treatment
plant" The treatment of wastewater belongs to the
overarching field of Public Works -
Environmental, with the management of human
waste, solid waste, sewage treatment, storm water
(drainage) management, and water treatment.

By-products from wastewater treatment plants,
such as screenings, grit and sewage sludge may
also be treated in a wastewater treatment plant.
If the wastewater is predominantly from municipal
sources (households and small industries) it is
called sewage and its treatment is called sewage
treatment. Vishvaraj Infrastructure Limited (VIL)
saw this A Civic Necessity and a Business
Opportunity.

In contrast the demand for fresh water is growing
rapidly, estimated to go from 813 BCM today to
1,447 BCM by 2050, whereas the resource base
remains constrained at 1,122 BCM. The industrial
sector, which is one of the major users of fresh
water, mostly puts fresh water to non-potable.
Wastewater treated up to secondary level can
easily be utilized for this purpose freeing up
massive amounts of freshwater for domestic
consumers. This can easily be achieved by
improving the municipal wastewater collection,
treatment and reuse thus not only recycling
wastewater which is otherwise lost but also save
the downstream water bodies from pollution.

This is the win-win proposition of VILs model
for the all the stakeholders, a unique example of
creating value from waste whilst contributing
positively to environmental sustainability.
Amongst the challenges thrown up by increased
urbanization in India one of the bigger ones is
massive increase in wastewater generation. The
Central Pollution Control Board (CPCB) estimates
that about 80 percent of the water supplied for
domestic use is discharged as wastewater.

This pollutes the downstream areas as it enters
untreated into these water bodies. Around 38,250
MLD of wastewater is generated by class I and
class II cities in India, which is estimated to
grow 3.5 times to 132,250 MLD by 2050. The
current wastewater treatment capacity can handle
only 30 percent of the total generation, out of
which too only 55 percent is operational. This
translates to an investment gap of over USD 7
Billion for class I and class II cities by
2016-17.

Project Showcase Nagpur 200 MLD STP Treatment
and Reuse on PPP basis. Nagpur is 10th largest
Indian city with 2.5 Mn population. Population
is expected to grow to 5 Mn in the next 25
years. 3rd largest and most industrialized city
after Mumbai and Pune in Maharashtra. The main
Objective is Providing Sewage Treatment for 200
MLD and possible reuse by potential Customers in
Nagpur.
