This case study showcases how the installation of solar photovoltaic (PV) panels at a water treatment plant in Rajkot has reduced greenhouse gas emissions and inspired the municipality to scale-up in other parts of the city.

This study seeks to understand factors that guide the decision-making process to adopt and implement the available arsenic-mitigation technologies in rural areas in the middle-Ganga Plain in India. A total of 340 households comprising 2500 people were surveyed.

In the present investigation photocatalytic degradation of an antibiotic rifabutin in aqueous solution with TiO2 as photocatalyst has been investigated under UV irradiation. The efficiency of degradation was quantified by several parameters such as effect of initial concentration, catalyst loading, pH and addition of H2O2 as a co-oxidant. The effect of operational parameters on the decolourisation and degradation under UV irradiation in TiO2 suspension has been investigated to find out the optimum conditions.

Neonicotinoid insecticides are widespread in surface waters across the agriculturally intensive Midwestern United States. We report for the first time the presence of three neonicotinoids in finished drinking water and demonstrate their general persistence during conventional water treatment. Periodic tap water grab samples were collected at the University of Iowa over 7 weeks in 2016 (May–July) after maize/soy planting. Clothianidin, imidacloprid, and thiamethoxam were ubiquitously detected in finished water samples at concentrations ranging from 0.24 to 57.3 ng/L.

We summarize reasons for mandating independent monitoring of greenhouse gas emission reduction projects. In support of our policy recommendations, we describe a case study of a program designed to earn carbon credits by distributing almost one million drinking water filters in rural Kenya to avert the use of fuel for boiling water. We compare results from an assessment conducted by our research team in the program area among households with pregnant women or caregivers in rural villages with low piped water access with the reported program monitoring data and discuss the implications.

The paper aims at highlighting the need for developing wastewater reuse as a sector, identifying the interventions that could help in the development of this sector. It also identifies suitable structures that can help in mainstreaming the implementation of wastewater reuse projects in the country.

The ever-growing population of India, along with the increasing competition for water for productive uses in different sectors – especially irrigated agriculture and related local water systems and drainage – poses a challenge in an effort to improve water quality and sanitation.

Question raised in Lok Sabha on Water Treatment Plants, 03/05/2016. As per the information furnished by the Ministry of Drinking Water and Sanitation (MoDWS), the details of funds allocated, released and utilized by the States / UTs under National Rural Drinking Water Programme (NRDWP) which include funds for setting up water treatment plants in toxic heavy metal affected areas in the country including Karnataka during the last 3 years and 2016-17 are given at Annexure I.

Water scarcity challenges industries around the world. Global population growth and economic development suggest a future of increased demand, competition, and cost for limited freshwater supplies.
