PREserwe - Intercepting Sewer Waste to Protect Marine Ecosystems.
PREserwe
(
Partnership
)
#OceanAction58480
Description
Preserwe, through its innovations Chakravyuh and Abhimanyu, is committed to reducing marine pollution by intercepting solid and semi-solid waste directly at sewer outfalls before it enters rivers. This system prevents downstream contamination of freshwater and marine ecosystems by removing over 80% of plastic and sludge waste from sewage flows.
Chakravyuh is a passive filtration unit that traps both floating and submerged solid waste in multi-layered chambers without disrupting flow. It is strategically placed at sewer junctions. Abhimanyu is a robotic scavenger arm that automates the extraction of sludge and plastics from Chakravyuh units, eliminating unsafe manual scavenging and improving waste handling efficiency.
The commitment involves piloting and scaling Chakravyuh and Abhimanyu across Indian river cities to prevent untreated waste from reaching oceans, particularly targeting the Godavari River. Waste collected is analyzed, segregated, and recycled or composted. IoT-based monitoring systems are being prototyped for remote oversight.
Governance is coordinated in partnership with municipal bodies, who will own, monitor, and maintain the infrastructure. Follow-up mechanisms include quarterly waste audits, ecological impact tracking, and open data sharing with local governments and academic institutions.
Preserwe aims to set a replicable model for decentralized sewer waste interception applicable across the Global South.
