The Kerala Water Authority is struggling to plug the demand-supply gap in the distribution of drinking water to lakhs of Kochiites.

According to official estimates, about 245 mld (million litres per day) to 250 mld is supplied from the pumping station in Aluva. The demand has gone up to around 400 mld. Officials involved in the distribution network said that the average daily consumption per family in the city is about 250 litres. In some places, the requirement is only about 130 litres to 150 litres. Demand for drinking water is balanced to a certain extent by this variation in consumption, they said.

Despite these observations, many parts of the Ernakulam district continue to reel under acute water shortage even before the onset of summer. Acute water scarcity has been experienced in areas like Fort Kochi, Chellanam, Vypeen, Kadamakudi, Piravom and North Paravur.

Thousands of local residents, especially those living in residential apartments, now depend on tanker lorries supplying drinking water.
