Developing Water-Sensitive Cities in India with Veena Srinivasan | The WELL Labs Show

Socio-hydrologist Veena Srinivasan (https://www.linkedin.com/in/veenasrinivasan/?originalSubdomain=in [https://www.linkedin.com/in/veenasrinivasan/?originalSubdomain=in])  joins host Pavan Srinath (https://www.linkedin.com/in/pavansrinath/?originalSubdomain=in [https://www.linkedin.com/in/pavansrinath/?originalSubdomain=in]) to unpack what it means to build water-sensitive cities in India — cities that look beyond pipes and taps, and start managing groundwater, rainwater, stormwater, wastewater, lakes and rivers as one connected system. As Indian cities grow, they often look farther away for water — to distant rivers, reservoirs and mountains. But Veena Srinivasan explains why this model has limits: cities pollute or ignore local water sources, depend heavily on groundwater, and spend enormous energy and money moving water across long distances. The episode explores how urban growth changes water demand, why sewage treatment often lags behind water supply, and how this contaminates lakes, drains and groundwater. Veena then outlines what a water-sensitive city would do differently: treat wastewater as a resource, support decentralised reuse, harvest rainwater based on local geography, manage stormwater and lakes better, and collect data on the full urban water system. Veena Srinivasan (https://welllabs.org/veena-srinivasan/ [https://welllabs.org/veena-srinivasan/])  is leading WELL Labs’ mission to transform scientific research into real-world impact by designing solutions that simultaneously create livelihoods and conserve the environment.

Canal Irrigation in Modern India with Teju Kumar N | The WELL Labs Show

Teju Kumar N (https://www.linkedin.com/in/tejukmr/ [https://www.linkedin.com/in/tejukmr/]), Assistant Engineer at the Advanced Centre for Integrated Water Resources Management (ACIWRM), Government of Karnataka, joins host Pavan Srinath (https://www.linkedin.com/in/pavansrinath/ [https://www.linkedin.com/in/pavansrinath/])  on this episode of The WELL Labs Show to unpack how canal irrigation works — from dams and command areas to distributaries, field channels, gates, aqueducts, and last-mile water delivery. India’s most productive farmlands are often irrigated, and canals remain central to India’s irrigation systems. In this episode, Teju explains how canal networks carry water from dams across large command areas, helping farmers grow beyond the monsoon and reduce dependence on uncertain rainfall. The conversation breaks down the engineering behind canals — from main canals, distributaries and field channels to gravity, slope, offtakes, gates, aqueducts, and concepts like duty and delta. Teju also traces Karnataka’s irrigation history, from wells, tanks and anicuts to large dams like the Tungabhadra Dam, before discussing canal modernisation through concrete lining, automated gates, SCADA systems, IoT, soil moisture sensors, and the Narayanpur Left Bank Canal. The episode also explores key challenges today: head-end versus tail-end inequity, changing crop choices, conjunctive use of surface water and groundwater, rising demand from drinking water and industry, and the role of Water User Cooperative Societies in improving last-mile irrigation. Teju Kumar N (https://aciwrm.karnataka.gov.in/136/Teju%20Kumar%20N/en [https://aciwrm.karnataka.gov.in/136/Teju%20Kumar%20N/en])  is an Assistant Engineer with the Advanced Centre for Integrated Water Resources Management (ACIWRM) in the Government of Karnataka.

Labour and Water Conservation with Karan Misquitta | The WELL Labs Show

Watershed researcher Karan Misquitta [https://www.linkedin.com/in/karan-misquitta/⁠]  joins host Pavan Srinath [https://www.linkedin.com/in/pavansrinath/] to unpack how water conservation, labour, and technology have shaped India’s landscapes over more than a century. This episode explores the evolution of watershed development — from colonial-era famine relief works to modern-day machine-led interventions. Karan explains how droughts historically led to labour-based public works, why soil and water conservation became central to rural employment programmes, and how structures like bunds, trenches, percolation tanks, and check dams transformed agricultural landscapes across India. The conversation also examines a critical tension: how do we balance creating employment at scale with building effective, durable water systems? Drawing on his research in Maharashtra, Karan traces the shift from labour-intensive watershed programmes to capital-intensive approaches driven by excavators, farm ponds, and large-scale recharge efforts — and what this means for groundwater, farmers, and policy today. Karan Misquitta [https://www.linkedin.com/in/karan-misquitta/⁠] is a Senior Researcher at WELL Labs, with a PhD in Geography. His work focuses on groundwater, rural water systems, and the political economy of watershed development in India.

Aquifers of North India and the Indo-Gangetic Plains | Vivek Grewal on The WELL Labs Show

Hydrogeologist Vivek Grewal (https://www.linkedin.com/in/viveksinghgrewal/ [https://www.linkedin.com/in/viveksinghgrewal/])  joins host Pavan Srinath (https://www.linkedin.com/in/pavansrinath/?originalSubdomain=in [https://www.linkedin.com/in/pavansrinath/?originalSubdomain=in])  once again to unpack the basic science of groundwater and to explain how groundwater behaves in one of India’s most important hydrogeological regions. Where does groundwater fit in the water story? Vivek explains why most of the world’s liquid freshwater exists underground, how rainfall becomes groundwater, and how rivers like the Ganga are sustained by flows beneath the surface. The episode then breaks down how aquifers work from porosity and fractures to recharge and baseflow - while debunking common myths about “hidden underground rivers.” Finally, the discussion turns to the Indo-Gangetic aquifer, explaining how it was formed and why regions like Punjab, UP, Bihar and Bengal face very different challenges - from depletion and salinity to arsenic contamination. Drawing from both field experience and hydrogeological research, Vivek also explains why western India faces severe depletion despite large underground storage, why eastern India may have more water but different access and quality challenges, and how a better understanding of groundwater is essential for managing agriculture, drinking water and long-term water security. Vivek Grewal (https://welllabs.org/vivek-singh-grewal/ [https://welllabs.org/vivek-singh-grewal/] ) is the Managing Partner with the Technical Consulting programme at WELL Labs.

Preparing for Bengaluru's Next Water Crisis with Gayathri Muraleedharan and Veena Srinivasan

Veena Srinivasan and Gayathri Muraleedharan join host Pavan Srinath on this episode of The WELL Labs Show to unpack the nature of Bangalore’s water crisis — what caused the severe summer crisis of 2024, why similar crises may recur, and what the city can do to avoid lurching from one groundwater emergency to the next. The conversation explores why Bangalore’s water crisis is not a “Day Zero” reservoir crisis like Cape Town or Chennai, but fundamentally a groundwater crisis. Veena and Gayathri explain how the city depends on both Cauvery water and groundwater, why the most acute pain is felt in newly developed peri-urban areas and dense apartment clusters, and how Bangalore’s hard-rock aquifers, uneven topography, and hyperlocal recharge patterns make the problem difficult to predict and manage. Drawing on WELL Labs’ work on urban water balances, groundwater dependence, wastewater treatment, and water reuse, the discussion examines how much water Bangalore needs, how much it receives from the Cauvery, and how much is being invisibly supplied through private borewells and tanker systems. They also explore why treated wastewater reuse, especially through decentralised sewage treatment plants in apartments and commercial complexes, may be one of the most practical ways to reduce pressure on the city’s fragile aquifers. The episode also reflects on what has changed since the 2024 crisis: greater seriousness around water reuse, more interest from apartment communities in running STPs efficiently, efforts by BWSSB such as the Green Star Challenge, and the need for stronger incentives, better monitoring, groundwater recharge, sponge landscapes, and more realistic water pricing. The conversation ends with a hopeful but grounded argument: that while Bangalore’s water crisis is systemic, the city also has many solutions that can be acted upon locally — by institutions, neighbourhoods, apartments, and public agencies alike.
