India is currently suffering high levels of water stress due to repeated droughts in recent years, exacerbated by poor water management practices. Unsustainable levels of ground water have been extracted and scarce surface water is often contaminated by waste.

The problem is compounded by poor sewage infrastructure. In most urban settings only about 20% of wastewater is covered.

Efforts by local authorities to tackle this problem, by requiring buildings of a certain size to have an onsite sewage treatment plant, were poorly policed. Now rules are being tightened up and new solutions are urgently needed.

Working with partners, Ashirvad developed a modular, hybrid sewage treatment plant, offering a range of benefits, including a 50-60% reduction in surface area making it compact and easier to install, advanced bio-media to withstand higher loads, less noise and reduced sludge output.

This highly advanced solution was developed at lightning speed, moving from design to standardisation after a three-phase pilot programme in around three months.
