Non-Revenue Water (NRW) or unaccounted-for water is high in Indian cities because of outdated water systems, illegal connections, leakages, poor maintenance and lack of proper mapping of the distribution system. The average NRW in India is between 30 to 50%. Clearly, there is a gap in our management of water and the solution may lie in reconsidering how we look at water flow.

In the race to achieve India’s National Solar Mission (NSM) targets, one important solar technology is slowly disappearing. Concentrated Solar Power (CSP), a solar thermal-based technology for power generation, which showed considerable technical potential, is being sidelined. It is losing out due to economics compared to its rival, solar photovoltaics (PV).

Can the application of data science and technology make the urban planning process more responsive to the changing patterns of spatial activity? Largely, yes. What the process needs is the continuous collection and analysis of appropriate urban data that can be envisaged spatially and analysed to obtain various possible types of correlation.

The launch of Ujwal DISCOM Assurance Yojana (UDAY) in November 2015 gave new hope to the ailing distribution companies (DISCOMs) in India. Karnataka signed up for UDAY with a view to improve its operational efficiency. The DISCOMs under the scheme have to reduce Aggregate technical and commercial (AT&C) losses to 14.2% , and bring down the gap between average cost of supply (ACS) and average revenue realisation (ARR) to zero by 2019.

In India, 75% of dispensaries, 60% of hospitals and 80% of doctors are in urban areas, serving just 28% of the population. Meanwhile, 72% of the population, who reside in rural areas, face a chronic lack of medical facilities

Reuse of industrial wastewater has been in practice for a long time in India, and this water is mainly used for agriculture purposes in nearby areas. However, this has led to high levels of heavy metal concentration in vegetables grown with industrial wastewater.
