Our cities will need a combination of centralised and decentralised wastewater treatment systems especially in urban pockets and smaller towns where formal sewerage system and treatment will be too expensive, write B Rajesh and Neerad Swaroop. Nearly 590 million people are expected to live in Indian cities by the year 2030. As per the 2011 census, decadal growth of urban population was 31 per cent,

IDFs are yet to take shape in the country
It would be purposeful for taking steps towards simultaneously developing IDF and bond market, says SK Goel, Chairman & Managing Director, IIFCL, Infrastructure Debt Funds (IDFs) are yet to take shape in the country as the infrastructure bond market is in its nascent stage. Till infrastructure bond market develops, IDFs may not find adequate avenues for investment and on the contrary till IDFs evolve, the infrastructure bond market may find it difficult to attract sufficient investments.

IDF should address asset-liability mismatch
The government should explore various options that can nurture IDF in an industry-friendly way, writes Vivek Rao. While conceptually Infrastructure Debt Funds (IDFs) would be very attractive for all stakeÂholders of the infrastructure sector including private sector developers, banks as well as the goverÂnment, IDFs would have to address certain challenges.

PPP and water management still don't jell
Private players have been shying away from PPP in water management due to lack of transparency in the system, longer gestation of return on investment and above all RoI is much lower compared to other infrastructure projects. With upsurge in economic activities and rapid growth in urbanisation, proper water management system has to be in place. According to a recent PwC report, almost 590 million people are expected to live in Indian cities by the year 2030.

Integrated planning for water & sewerage system
Techno-economical methods for dilution and tertiary treatment of sewage are an inevitability to achieve the new and more stringent quality norms, writes PK Jain. In India, increasing water consumption is only complicated by the high level of unaccounted-for water (UFW). Keeping this in mind, the government has taken several initiatives. The most ambitious plan for abatement of pollution of water was launched on 14 June 1985 by the then Prime Minister Rajiv Gandhi.

Government should take holistic approach
In order to secure future water needs, the government will have to play a major role, both functionally and financially. Technologies focus on the techno-ecoÂnomic mix for fulfilment of viability requireÂments and also technical requireÂments for specified re-use specified for industrial and domestic sector. Uniform standards are adoÂpted for water quality parameters for the specified re-use to enable the client/contractor to choose the optiÂmum technology at a rational cost.

How zero liquid discharge plants work
Zero liquid discharge plants minimise the consumption of freshwater and by the reuse of wastewater it helps relieve freshwater availability limitations in places where it is scarce or expensive. Ganesh Pangarkar explains the technology and process. Power production has an impact on the environment. Besides the fuel gas, other emissions leave the power production process, noteworthy among which is water loss in the water/steam cycle.
