How Much Does an RO Water Plant Cost?

If you are planning to enter the water business or install a system for your institution, one big question comes to mind: How much does an RO water plant cost in India? The answer depends on several factors—capacity, water quality, and setup requirements. A small 100 LPH RO plant may cost around ₹80,000, while a large 2000 LPH commercial system can go beyond ₹7 Lakhs.

Let’s walk through the details step by step so you understand where your money goes and what investment makes sense for you.

Why RO Water Plants Are in High Demand

With urbanization, rising population, and falling groundwater quality, the need for pure and safe drinking water has become urgent. Schools, hospitals, hotels, restaurants, factories, and residential societies cannot rely on untreated water anymore. Installing a commercial or industrial RO plant ensures a steady supply of potable water, compliant with BIS standards.

This increasing demand is exactly why more entrepreneurs and businesses are investing in RO plants—it’s not just about water safety, but also a growing business opportunity.

Factors That Influence RO Water Plant Cost

Before you check the price tag, you must understand what drives the cost of an RO plant:

• Plant Capacity (Litres per Hour – LPH): The higher the capacity, the higher the cost.

• Raw Water TDS & Quality: Heavily contaminated or hard water needs additional treatment units.

• Material Used (FRP or SS): FRP is economical; SS is durable but costlier.

• Additional Features: Chillers, bottling machines, storage tanks, and automation panels add to investment.

• Infrastructure & Land: Sufficient space is required, especially for large plants.

• Certification & Approvals: ISI certification, BIS compliance, and Pollution Control approvals involve costs.

• Maintenance & AMC: Long-term service contracts also influence overall investment.

Cost Breakdown of RO Water Plants in India

Instead of just giving you figures, let’s walk through capacities one by one and see where the money goes:

• 100 LPH RO Plant
  A small setup for clinics, offices, or small hostels. The plant itself costs ₹80,000 – ₹1,10,000. With land preparation, installation, and minor storage, expect the total to reach around ₹1.2 Lakhs.

• 250 LPH RO Plant
  Ideal for mid-size restaurants, schools, or hotels. A 250 LPH setup usually costs ₹2.2 – ₹2.5 Lakhs, and with transport and approvals, you may spend ₹2.7 Lakhs.

• 500 LPH RO Plant
  One of the most popular choices for commercial use. Costs hover between ₹2.7 – ₹3 Lakhs. Add a bottling unit and packaging system, and investment may cross ₹4 Lakhs.

• 1000 LPH RO Plant (with Chiller option)
  Widely used in hospitals, large hotels, and industrial canteens. The base cost is ₹5.5 – ₹6 Lakhs, and if you add a chiller, it can reach ₹6.5 Lakhs.

• 2000 LPH RO Plant
  Perfect for large factories and high-demand institutions. Costs range ₹7 – ₹7.5 Lakhs, and with storage tanks, pipelines, and certification, it may go close to ₹8 Lakhs.

This makes it clear: the bigger the setup, the higher the cost—but also the higher the revenue potential.

Beyond Cost: Other Investments You Must Consider

Many new investors assume the plant cost is the only expense, but there are hidden yet necessary investments:

• Certification Costs: You need BIS certification, ISI approval, and in many states, a Pollution Control Certificate.

• Testing & TDS Analysis: Water must be tested before plant design.

• Packaging & Distribution: If you’re bottling water (20L jars or smaller bottles), you’ll need filling machines, caps, and labels.

• Marketing & Branding: Reaching customers in your area requires promotional spend.

• AMC & Spare Parts: RO membranes, filters, and pumps need regular replacement.

Factoring these ensures you don’t underestimate your budget.

Is an RO Water Plant Profitable?

Yes, absolutely. Safe drinking water is not optional—it’s a necessity. That’s why schools, offices, and industries are ready to pay for reliable supply.

A 1000 LPH plant can produce 1000 litres per hour. Even if you sell water at just ₹10 per litre, that’s ₹10,000 a day. In less than a year, you can recover your investment and start earning profits. For packaged drinking water businesses, margins are even higher.
