Fluoride, a Drying Well and ₹9.5 Lakh

Fluoride benchmark. The BIS permissible limit for fluoride in drinking water is 1.0 mg/L, relaxable to 1.5 mg/L only where no alternative source exists. The mottled enamel in 40 children is dental fluorosis - the harm is already occurring, so the choice is a health decision, not a comfort decision.

Option A. At 3.2 mg/L the borewell water is more than double the relaxation limit and cannot be supplied alone. Blending with the 0.8 mg/L well water to reach 1.0 mg/L requires: 3.2x + 0.8y = 1.0(x + y), so 2.2x = 0.2y, i.e. y = 11x - eleven litres of well water for every litre of borewell water. And the wells are dry exactly in mid-April to mid-June, the peak demand period, so the dilution water is unavailable when it is needed. Blending fails where it matters. Reject A.

Option C. Output stays at 0.8 mg/L, acceptable but not a solution to the two-month dry spell, and it carries the highest recurring cost (₹60,000 a year) for the least improvement. The village would pay most for the smallest gain, and filter replacement is the first thing to lapse when funds tighten. Reject C as the primary option.

Option B. Spring water at 0.6 mg/L is well below every limit and is perennial - it addresses both the fluoride problem and the seasonal gap. Capital of ₹7.9 lakh leaves ₹1.6 lakh from the ₹9.5 lakh for a storage tank, standpost platforms and protection of the stream crossing. Adopt B, with three riders: test the spring bacteriologically, since microbial contamination is now the larger risk; chlorinate or install point-of-use treatment at the standpost if the test is positive; and keep the dug wells maintained as dry-season backup.

No - the contract should not be signed this week.

The rules. Simlabahal lies in a Fifth Schedule area, so the Panchayats (Extension to Scheduled Areas) Act, 1996 applies: the Gram Sabha's competence extends to drinking water, minor water bodies, land and the selection of beneficiaries, and it must be consulted before such works are taken up. Under the 73rd Constitutional Amendment (Articles 243G and 243A), the Gram Sabha is the constitutional body at the base of the system, and both untied Fifteenth Finance Commission grants and District Mineral Foundation priority works are required to be approved by it. A contract signed without a Gram Sabha resolution is exposed to audit objection, and works can be stopped mid-construction - the worst outcome for the village.

The practical reason the rule exists. The ₹40,000 a year running cost of the pipeline is not paid by the contractor or the block; it is paid by the village. The Gram Sabha is the only body that can commit the village to that recurring charge - deciding the household contribution and the panchayat's top-up from its own revenue. Without that commitment the pipeline is commissioned and then abandoned in two or three years, which is exactly what happens to schemes pushed through without local ownership.

Action this week: convene the Gram Sabha with the three proposals, the laboratory reports, capital and running costs and the proposed monthly contribution; record the resolution; then tender. The delay is one week; the alternative is a dead asset.

Per-household arithmetic. ₹40,000 ÷ 210 = ₹190 per household per year, about ₹16 a month. That is affordable even in a low-income village, but it will not be collected unless a body is made responsible for it and the tariff is agreed before the scheme starts.

Proposal.

• Set a household contribution of ₹25 a month (₹300 a year): 210 × 300 = ₹63,000, covering the ₹40,000 running cost and leaving about ₹23,000 for repairs, valve replacement and pipeline maintenance at the stream crossing.
• Vest collection in a village water and sanitation committee with at least half its members women, since they are the main users of the standposts; publish a simple monthly account on the notice board.
• Keep one trained local plumber on a retainer rather than calling one from the block each time.
• Ring-fence the panchayat's own revenue and the tied water component of the Fifteenth Finance Commission grant as a reserve for major repairs.

Comparison that settles the argument. Option C demanded ₹60,000 a year - ₹286 per household - and still left the village without water for two months. Option B asks for ₹16–25 a month and delivers safe water all year. The affordability question is therefore not 'can the village pay ₹40,000?' but 'can it pay more for a worse service?', and the answer is no.

One caution to record in the resolution: the tariff must be revised if the spring yield falls, so the committee should review it every three years.
