Census Town by the Corridor

A census town of 85,000 beside a new industrial corridor grew 34% in a decade. Workers live in 12,000 rented one-room units; 18% of households are in informal settlements on poramboke land. Water supply is 70 litres per capita per day (LPCD) against a norm of 135, with only six hours of supply. Sewage is untreated and flows into a tank that recharges 200 shallow wells. Primary school enrolment is 96%, but secondary dropout is 21%, higher for girls. The town has no municipality; it is governed by a village panchayat with a tax base of ₹4.2 crore and 14 staff. The corridor authority offers a one-time grant of ₹30 crore for either (a) a piped water and sewer network, or (b) a secondary school plus skill centre. The state says open-defecation-free status is claimed, but 40% of households lack individual toilets.

1. Classify the settlement and explain two reasons why its civic status lags its economic function.

Classification. It is a census town: population above 5,000 (85,000), high density, and more than 75% of male workers in non-agricultural employment. It is not a statutory town because it has not been notified as a municipality; it remains under a village panchayat.

Reason 1 - Growth outpaced statutory notification. A 34% decadal growth driven by an industrial corridor means migrants arrived before the state revised municipal boundaries. Notification is a legal process, not an automatic response to population size.

Reason 2 - Fiscal and administrative capacity. The panchayat has only ₹4.2 crore and 14 staff for 85,000 people. It cannot fund or manage sewerage, water treatment or building regulation. The corridor authority creates the economic demand, but the civic body that legally hosts the workers has a rural tax base. The 18% living on poramboke land further complicates service provision, because insecure tenure discourages household investment in toilets and piped connections.

2. Which grant use would improve human development more in five years? Justify with the data and note one risk.

Recommendation: the piped water and sewer network.

Water supply is 70 LPCD against a norm of 135 - only 52% of the standard. Untreated sewage recharging 200 shallow wells creates a direct faecal-oral route, and 40% of households lack toilets despite an ODF claim. These are immediate health and dignity deficits that affect the whole population, especially women and children.

The school option addresses a real problem: 21% secondary dropout, higher for girls. But primary enrolment is already 96%, and a new school building does not by itself solve dropout if the causes are child labour, migration or lack of girls' toilets. Water and sanitation also improve school attendance indirectly.

Risk. A one-time ₹30 crore capital grant can create a network that the 14-staff panchayat cannot operate and maintain. Without a tariff, an O&M contract and extension to informal settlements, the asset will deteriorate. The grant should therefore require a maintenance plan and tenure arrangements for poramboke households.

3. How would you measure whether the town is becoming more sustainable? Give three indicators and explain what each would show.

Read the worked answer

Indicator 1 - Share of households receiving at least 135 LPCD for 12+ hours. This measures whether the water network is closing the 70-to-135 gap and whether supply is reliable, not just connected.

Indicator 2 - Share of sewage treated before discharge. This tests whether the untreated flow into the recharge tank is reduced. It is more meaningful than the percentage of households with toilets, because a toilet without a sewer or safe containment still contaminates groundwater.

Indicator 3 - Secondary dropout rate, disaggregated by sex. This captures human-development sustainability. A falling overall dropout rate that hides a rising girls' rate would not be sustainable.

A fourth possible indicator is the share of households in informal settlements, or panchayat own-source revenue per capita, because both reveal whether civic capacity is catching up with economic growth.
