The Quiet Water Waste in India’s High-Rises

One aspect of India’s urban water crisis that I find particularly striking — and often under-discussed — is the behaviour inside high-rise apartments.

In many Indian cities, a growing share of the middle and upper-middle class now lives in multi-storey buildings. On paper, this looks efficient: shared infrastructure, denser living. In practice, it frequently drives higher per-person freshwater consumption. People flush toilets more freely, clean floors and vehicles with running water, take longer showers without any sense of limit, and leave minor leaks unattended for weeks because the cost is buried in a common maintenance bill or a flat monthly charge. When water does not feel expensive or scarce at the individual level, restraint disappears.

This is not a small issue. Urban domestic demand is rising faster than many city utilities can supply. In high-rises, the problem is amplified by:

• Lack of individual metering or volumetric billing in many societies  
• Zero marginal cost for the resident once the maintenance fee is paid  
• Design that prioritises convenience (powerful showers, multiple bathrooms, frequent cleaning) over efficiency  
• A cultural shift where continuous high-pressure supply is treated as a basic entitlement rather than a scarce resource  

The result is a silent but steady increase in the burden on already stressed municipal sources, groundwater and tanker supplies. Cities end up chasing more supply — new pipelines, distant reservoirs, or deeper borewells — while a significant portion of the water that reaches these buildings is used more liberally than necessary.

I see this as both a behavioural and a governance failure. We have spent years focusing on expanding supply and improving treatment. Those efforts remain essential. But without parallel attention to demand management inside homes, especially in the fastest-growing housing typology, we will keep running harder just to stay in the same place.

Practical steps that can make a difference are not complicated:

• Mandatory individual metering and volumetric billing in all new high-rises, and gradual introduction in existing ones  
• Stronger building codes that require low-flow fixtures, dual-flush toilets and leak-detection systems  
• Society-level incentives or penalties linked to overall consumption  
• Simple awareness that treats water the way we now treat electricity or fuel — as something whose waste has a visible personal cost  

Until the person living on the 12th floor feels the consequence of an extra-long shower or a dripping tap, the pressure on freshwater sources will continue to grow. Supply-side solutions alone cannot keep pace with this kind of demand.

This urban behavioural reality sits alongside the larger challenges I wrote about earlier — monsoon variability, groundwater depletion, wastewater under-utilisation and the need for better pricing signals. Together they underline a simple truth: India’s water future will be decided as much by how carefully we use what we have as by how much new water we manage to bring in.

The high-rise apartment is a good place to start changing that equation.
