Track All Plant Opex
Purification is only the base cost. The true challenge is tracking the opex of your delivery team, vehicle maintenance, and missing jar replacement costs.

Pani Saaf Karne Ka Kharcha: Commercial RO Purification Cost Guide
Running a clean, high-quality water filtration plant requires absolute control over your production ledger. Plant owners must know: pani saaf karne ka kharcha (how much does it cost to purify water) and RO filter cost per litre? Our water purification cost calculator breaks down water sourcing expenses, electrical utility units, reject rates, and consumable packaging rates.
Raw water purification margins are generally very high. Purified water costs less than ₹0.30 per Litre to produce. However, when you factor in periodic filter replacements, NABL testing chemicals, and packaging caps/shrink wraps, your true production cost per 20L jar can easily range between ₹4 and ₹8.
Granular Cost Elements in RO Operations
To evaluate your plant's efficiency, our calculator accounts for the following parameters:
- Raw Water Sourcing Cost: If you buy private water tankers, raw water costs about ₹0.20 per Litre (₹1,000 per 5,000L). Municipal water is cheaper (₹15 to ₹25 per KL), while borewell water has ₹0 raw procurement cost but consumes pumping electricity.
- Reject Water Ratios: Standard industrial RO plants reject about 40% to 50% of the input raw water as waste (concentrate). This means to produce 5,000 Litres of pure drinking water, you must process at least 8,300 Litres of raw water, which increases water sourcing and pumping bills.
- Electricity Consumption: High-pressure RO pumps and feed pumps consume approx 3.0 kWh (units) of power per 1,000 Litres of raw water processed. If your commercial power tariff is ₹9/unit, this represents a major opex factor.
- Amortized Consumables & Filters: Sand media and carbon filters must be replaced annually, while RO membranes (which cost ₹15,000 to ₹25,000 each) must be replaced every 1.5 to 2 years. Our calculator amortizes this into a monthly fixed maintenance cost.

How PaniHisab Simplifies Plant Opex & Ledger Tracking
Water plant owners must balance raw production costs with logistics. If your purification cost per jar is ₹6, and delivery boy commissions are ₹8, and delivery vehicle fuel represents ₹6, your total cost price is ₹20. If you sell at ₹30, you make a ₹10 profit.
PaniHisab helps you manage these calculations dynamically. The app features a centralized opex ledger where you can record daily production volumes, electric utility bills, fuel logs, and worker payroll. It combines this with active delivery logs to show you your true net profit margin per jar, helping you identify cost leakages and increase returns.
Frequently Asked Questions (FAQ)
Pani saaf karne ka kharcha kitna hota hai? (What is the purification cost per 20L jar?)
The standard purification cost for a 20L drinking water jar ranges between ₹4.5 and ₹7.0. This includes electricity (approx ₹1.5), consumables like caps/sleeves (₹2.0), chemical dosing (₹0.5), and amortized filter/membrane wear (₹1.5). This does not include delivery logistics or wages.
What is the typical electricity consumption of a 1000 LPH RO plant?
A 1000 LPH (Litres Per Hour) industrial RO water plant consumes approximately 3.0 to 4.5 units (kWh) of electricity per hour of active operation, depending on the TDS levels of the raw source water.
How often should sand and carbon filter media be replaced in a commercial plant?
The active media inside sand and activated carbon filters should be replaced every 12 to 18 months to prevent microbial growth and ensure optimal filtration efficiency, protecting the expensive RO membranes down the line.
