Water companies globally are developing technologies and management systems to deal with these challenges. Vishvaraj Infrastructure Limited (VIL) however understands that the Indian context is different and it needs solutions which are local, competitive and socially acceptable. We develop implementation strategies keeping local situation in perspective as water is a very sensitive subject in our country. For us, driving innovations, creating sustainability, technological advancements, environmental friendliness and people’s involvement are the key drivers for the company in this sector.
Waste Water Reuse: Vishvaraj Infra saw this as 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 VIL’s 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. 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 and 3rd largest and most industrialized city after Mumbai and Pune in Maharashtra.
