From village population to total project cost — 30-year design, 55 LPCD, FHTCs, tube well, ESR, rounded cost estimate.
📘 Read the full CPHEEO Chapter →The Jal Jeevan Mission is the largest rural water supply programme in history — ₹3.6 lakh crore, 19 crore functional household tap connections (FHTCs), 100% coverage target. This calculator runs the standard design formula for a single-village scheme from the village population to the total project cost, following CPHEEO Chapter 14 and BIS 1172:2012 standards.
The JJM design basis: 55 LPCD (upgraded from the older CPHEEO value of 40 LPCD to reflect modern rural standards of living), peak factor 3.0 (rural usage concentrates in morning/evening hours more than urban), FHTC inside every household premise. Tube wells with 12-hour pumping capacity are standard; ESRs sized at 1/3 of daily demand for balancing; solar pumping increasingly common.
Based on the CPHEEO Manual on Water Supply and Treatment, published by the Central Public Health and Environmental Engineering Organisation, Ministry of Housing and Urban Affairs, Government of India.
Size a rural water supply scheme under Jal Jeevan Mission — 55 LPCD design, peak factor 3.0, FHTC count, tube well yield, ESR, and project cost.
Tube well yield tells you the pump capacity. For < 20 m³/hr, a 5-10 HP pump suffices (standard village-scale). For > 30 m³/hr you may need multiple tube wells or a deeper well.
ESR capacity at 55 m³ is small — a 60 m³ precast ESR is the standard JJM unit (10-20 lakh). For larger villages or multi-village schemes, step up to 100 or 200 m³.
The cost estimate is approximate — actual varies with source distance (long transmission adds cost), terrain (rocky vs alluvial), distribution network density, treatment needs (fluoride, arsenic, iron). Use this for planning; get competitive quotes for procurement.
