Mansi Jain and Digital Paani: redefining water recycling with smart technology

Business Remedies | Rajshree Upadhyaya | Mansi Jain and her father Rajesh Jain launched Digital Paani in 2020 with a simple but urgent conviction that India’s lost and leaking water systems could be fixed with software and sensors. Born from Mansi’s background in environmental economics and years of conversation around engineering and operations at the family dining table, the company — legally Digital EcoInnovision Pvt Ltd and popularly known as Digital Paani — set out to turn manual, error-prone sewage and effluent treatment plants into digitally managed, accountable assets. The founders’ complementary strengths — Mansi’s policy and sustainability training and Rajesh’s decades of hands-on wastewater engineering — shaped a product that aimed to be pragmatic rather than theoretical from day one.

Digital Paani’s core offering is an IoT-enabled SaaS platform that threads together sensors, automation, live water accounting, and operator guidance so plants can treat, recover, and reuse more water with fewer breakdowns. Where many plants relied on intermittent manual checks and patchy maintenance, the platform provides 24/7 visibility, WhatsApp alerts, automated control loops, and performance analytics so teams can prevent failures and improve compliance. This practical combination was designed to appeal to large industrial clients and real estate operators who need reliable results rather than experimental pilots. The company itself frames the problem bluntly: a majority of installed plants underperform or fail, and fixing operations at scale required digital-first tools.

The results the founders point to are tangible. By partnering with industrial and institutional operators, Digital Paani reports managing tens of millions of litres of wastewater daily across multiple sites, bringing underperforming plants back online and reducing operating costs and environmental risk. Those outcomes helped the startup land marquee customers and a seed round that received attention in 2023, a financing event that underscored investor belief in water tech as climate tech and in the company’s route to scale.

A wider audience learned about the company when Mansi took the pitch to Shark Tank India Season 3, where the founders asked for funding while framing the public health and regulatory urgency of fixing wastewater operations. The national visibility that comes from television amplified Digital Paani’s story and introduced it to a mainstream viewership that rarely sees climate tech framed in everyday terms. The appearance did not immediately translate into a deal on the show, but it did expand awareness as the founders balanced product delivery with growth ambitions.

As of 2025, Digital Paani remains operational. Its website and social media pages remain active, sharing updates about new projects and wastewater management deployments. The company continues to work with industrial clients, builders, and institutions to optimize water reuse and sustainability compliance. For readers interested in founder-led climate solutions, the company offers a compact case study in how domain expertise paired with digital tools can convert a chronic infrastructure problem into a replicable service model — a quiet but powerful reminder that technology, when grounded in real-world experience, can solve some of India’s most persistent environmental challenges.
