Manhole-cleaning robot Bandicoot successfully completes trial run in Thiruvananthapuram
The spider-shaped robot developed by a team of engineers in Kerala to clean manholes has successfully completed a trial run in Thiruvananthapuram. Christened "Bandicoot", the robot is capable of cleaning manholes and sewers with precision, thereby eliminating the need for human intervention. It takes the robot 15 minutes to clean small sewers; unclogging bigger ones require around 45 minutes. Following the successful test run, the Kerala water authority has decided to use Bandicoot to clean all sewers in the capital.

No Veeranam water for Chennai city as tank water levels drop
The supply of water to Chennai from the Veeranam tank in neighbouring Cuddalore district has been stopped owing to low storage levels. The water level stood at two to three feet as against the tank's maximum of 47.5 feet. The tank has not been receiving inflow from the Mettur dam, which resulted in the drop in water levels. The Public Works Department, however, proposes to quench Chennai's thirst by supplying water drawn from Paravanar River instead.
Gujarat water supply management highly skewed in urban areas, says CEPT study
The Performance Assessment System of water resources conducted by CEPT University finds Gujarat's urban water supply management to be highly skewed. Studies point to a great deal of inequity and a lack of accountability, in terms of both groundwater and surface water exploitation in the state's urban pockets. Bigger municipal corporations and more affluent localities have been found to end up with more water.
Unique membrane developed by BARC makes it possible to design low-cost water purification technologies
BARC has developed a unique membrane-based low-maintenance water purifier which does not require electricity to function. These portable purifiers are touted to be the perfect solution for small-scale entrepreneurs as one unit is capable of supplying water to four other households apart from the one it's installed in. A ‘tabletop’ model for double filtration fit for rural areas has been designed in addition to charged nano-filtration units and spiral systems for desalination.
