Indore, despite being India's cleanest and premier 'water plus' certified city, is grappling with a severe structural water deficit driven by a widening gap between municipal distribution and actual gross consumption. Out of the city's 85 wards, 75 are currently experiencing acute water shortage.
Water Demand and Supply Gap
The total daily water demand for Indore's estimated population of 35 to 40 lakh spans a wide spectrum. Domestic consumption alone requires 620 million liters per day (MLD), based on an average per capita usage of 155 liters. When factoring in commercial operations, the city's gross daily requirement escalates to nearly 900 MLD.
To fulfill this need, the Indore Municipal Corporation (IMC) sources a bulk daily supply of 440 MLD from the Narmada pipeline phases and Yashwant Sagar. However, the actual net delivery reduces to between 300 and 320 MLD due to infrastructural leaks. Furthermore, 30% of the urban populace lacks functional Narmada pipeline connections, forcing the civic body to deploy over 700 emergency water tankers daily.
Groundwater Overexploitation
To bridge the massive 580 MLD deficit, the city relies heavily on sub-surface water. Experts estimate that Indore's groundwater exploitation rate has reached 120% of its sustainable yield, causing a record annual drop in the water table. Official data reveals that out of 6,500 government-operated borewells, approximately 50% have completely dried up this season. Currently, only about 10% of the total extracted volume is successfully recharged back into the ground annually.
Slow Implementation of Rainwater Harvesting
Institutional countermeasures remain slow. Although municipal bylaws mandate the installation of rooftop rainwater harvesting systems for all structures built on plots of 1,500 square feet or more, implementation has lagged. Till date, only 1.25 lakh properties have installed the system. Ahead of the upcoming monsoon, the IMC has set a modest target of 15,000 new installations, of which only 4,000 have been completed so far. This weak infrastructure keeps critical local reservoirs like Sirpur, Bilawali, Yashwant Sagar, and Pipliyahana under continuous ecological pressure.
Future Prospects
The IMC has started working on the Narmada Phase-IV project to supply a total of around 900 MLD to Indore. Of this, 620 MLD can meet domestic requirements, while the remaining 280 MLD could be supplied for commercial purposes. However, this phase will be completed by 2029. Until then, recharging groundwater levels and strengthening ponds and wells seems to be the only viable solution.
