How It's Calculated
By Meter Reading (Metro — Slab):
0-10 KL × ₹3.50 + 11-20 KL portion × ₹6 + >20 KL portion × ₹9 + Fixed ₹100

By Activities:
Daily litres = sum of all activity litres
Monthly KL = Daily litres × 30 ÷ 1000

Per-Person Daily Usage:
(Monthly KL × 1000) ÷ (Persons × 30)

Annual Bill = Monthly Bill × 12

WHO Benchmark: 50 L/person/day (basic) · 100 L/person/day (comfortable)
Tariff Reference (Indicative):
Metro: Slab 0-10 KL @₹3.50 | 11-20 KL @₹6 | >20 KL @₹9 | Fixed ₹100/mo
Tier-2: Flat ₹4/KL + ₹80/mo fixed
Tier-3: Flat ₹3/KL + ₹60/mo fixed

Frequently Asked Questions
How is the water bill calculated in India?
In India, water bills are calculated based on monthly consumption measured in kilolitres (KL). Most cities use a slab-based tariff — Metro cities like Delhi, Mumbai, and Bangalore charge approximately Rs. 3.50/KL for the first 10 KL, Rs. 6/KL for 11–20 KL, and Rs. 9/KL above 20 KL, plus a fixed monthly charge. Tier-2 cities typically charge a flat Rs. 4/KL, while Tier-3 towns charge around Rs. 3/KL. Older areas with flat-rate connections pay a fixed monthly amount regardless of usage.
How much water does a family of 4 use per month?
A family of 4 in India typically uses 15–25 KL (kilolitres) per month — around 125–208 litres per person per day. Key activities include daily showers (~40L each), toilet flushing (~50L/day for 5 flushes per person), drinking and cooking (~12L/day for 3 uses), and laundry (~80L per wash cycle).
What is the average water bill per month in India?
The average monthly water bill in India ranges from Rs. 150 to Rs. 600 for a typical household. In Metro cities, a family consuming 15 KL/month pays approximately Rs. 185–250 including fixed charges. Tier-2 city residents pay Rs. 140–240 for similar usage, and Tier-3 towns typically see bills of Rs. 105–210/month. These figures are indicative and vary by municipality.
How can I reduce my water bill?
You can reduce water usage through several steps: (1) Fix leaks — a dripping tap wastes 10–15 L/day and can cost Rs. 150–200/year extra. (2) Install low-flow showerheads to cut bathing from 40L to 20L per shower. (3) Run washing machines only on full loads. (4) Water plants early morning to reduce evaporation. (5) Reuse RO reject water for mopping or flushing. (6) Reduce car washing frequency. Combined, these changes can cut consumption by 20–35%, saving Rs. 300–800/year.
