8,400 residents and 14,000 visitors: choosing the first lever in a hill town
A hill town of 8,400 residents receives, on peak weekends in May and June, about 5,600 vehicles a day carrying roughly 14,000 visitors. The municipal council's own figures: solid waste peaks at 26 tonnes a day against 9 tonnes off-season; the composting and materials-recovery plant is permitted for 15 tonnes a day; two of five refuse compactor trucks await spare parts; the sewage treatment plant is rated 1.2 MLD while measured inflow is 1.9 MLD, and its outfall joins a river 11 km upstream of a town of 40,000 that draws drinking water from the same river; May water supply is 1.9 MLD against an estimated demand of 2.6 MLD, with tankers making up the difference. The council must decide within 10 days and has 4.2 crore rupees this year. On the table: a cap on vehicles, a congestion fee of 200 rupees per vehicle, a ban on identified single-use plastics, a new waste transfer station 9 km away, and deferring all decisions to next year. The traders' association says a fee will kill the season.
1. Rank the three problems by the risk they create and identify the one decision that cannot wait, with reasoning.

Ranking: sewage first, waste second, water third on urgency.
Sewage. 1.9 MLD inflow against a 1.2 MLD plant means 0.7 MLD reaches the river untreated, every day, peak season or not. That river is the drinking water source for 40,000 people 11 km downstream. This is the highest risk for three reasons: the harm is continuous rather than episodic; it is a legal exposure under the water pollution law and the polluter-pays principle; and the people who bear the harm have no vote in this council, which is exactly why the council will tend to underweight it.
Waste. 26 tonnes against a 15-tonne plant leaves 11 tonnes a day unprocessed at peak. Serious, visible, and a real risk of open burning and leachate on hill slopes, but it has a buffer: waste can be stored or transferred for a few days far more safely than sewage can.
Water. 0.7 MLD short in May, covered by tankers. A growing problem, not an acute contamination event, and the tanker is doing real work.
The decision that cannot wait: stop the untreated bypass and sanction augmentation or interim treatment of the STP this year. Everything else can be sequenced; the river cannot wait a season.
2. Compare the vehicle cap and the congestion fee on effectiveness, equity and enforceability, and recommend one or a hybrid.

Vehicle cap. Effective and easy to explain: one number, one gate, one board. But it needs a clear legal basis in the municipal or transport rules, an enforcement point at the entry to town, and it leaks badly, because vehicles park three kilometres out and passengers continue in. It also falls hardest on the day visitor in a shared taxi and not at all on the operator who runs ten buses.
Congestion fee. Raises revenue, and if differentiated by vehicle size and time of day it can spread the peak and charge the heavier users more. Its weakness is that a fee chosen for revenue stops being a cap: 200 rupees is trivial for a five-seat SUV and heavy for a shared taxi with eight passengers. Enforcement leaks through bypass routes, and the traders' fear is rational unless they can see the money come back as something they value.
Recommendation: a hybrid, in this order. A differentiated fee, with private cars and peak hours paying, and buses, shared taxis, local residents and emergency vehicles exempt; the revenue visibly earmarked to free shuttle buses from the parking point and to the STP and waste plant; and a hard daily entry ceiling that triggers once the road or parking capacity is reached. A cap without a shuttle is a ban on the poor, and a fee without a ceiling is just a rent. Publish the counts and the collections monthly, because the credibility of the scheme is the enforcement.
3. With 4.2 crore rupees you cannot fix everything. What will you fund first, what will you fund with conditions, and what will you explicitly refuse to fund this year?
Read the worked answer
Fund first. The STP augmentation or interim treatment, because it addresses the 0.7 MLD gap that harms people outside the town. Add the repair of the two compactor trucks, which is cheap, quick and adds haulage capacity this season, and source segregation in the three busiest wards, which raises the plant's effective capacity without new capital.
Fund with conditions. The waste transfer station only with three things in place: a waste characterisation study so its size is not guessed, a leachate and drainage plan, and a siting process that excludes landslide-prone ground and spring recharge zones. Also require a written operating commitment for the years after this one, because a transfer station with no onward disposal is a dump with a new name.
Refuse this year. A new landfill or incinerator, because there is no siting, no data and no operator, and a badly sited landfill on a hill slope is worse than the present problem. Refuse beautification and signage spending while the STP bypasses. Refuse a fresh single-use plastic ban of my own, because the identified single-use plastic items are already prohibited nationally since 2022 and the enforcement gap, not the notification, is the issue, so enforce what exists at zero cost while building a local alternative supply chain. And refuse the deferral outright: deferring is not a neutral option when 0.7 MLD is flowing into a drinking water source.
