Sewage Treatment Plant Solutions We Offer in India
We manufacture and install four core types of sewage treatment plants. Each technology has specific advantages depending on your project type and capacity requirement.
1. MBBR Sewage Treatment Plant
MBBR (Moving Bed Biofilm Reactor) is one of the most widely used sewage treatment technologies in India. It uses specially designed plastic media that provide a large surface area for beneficial microorganisms to grow and break down organic pollutants in wastewater.
MBBR systems are known for their reliable performance, low maintenance requirements, and compact design. They can efficiently handle fluctuations in wastewater flow and load, making them ideal for residential societies, hotels, schools, hospitals, and commercial buildings.

3. MBR Sewage Treatment Plant
MBR (Membrane Bioreactor) combines biological treatment with membrane filtration technology to produce high-quality treated water. The membrane acts as a physical barrier, removing suspended solids, bacteria, and other contaminants from wastewater.
MBR systems are ideal for projects that require superior water quality for reuse applications such as toilet flushing, landscaping, cooling towers, and industrial processes. Due to their compact footprint and excellent performance, MBR plants are commonly installed in hospitals, hotels, IT parks, and premium commercial developments.

How Much is Sewage Treatment Plant Cost in India?
One of the most common questions we get is: how much does a sewage treatment plant cost in India? The honest answer is that STP cost depends on several factors. There is no single fixed price, and any vendor who quotes a price without understanding your project is giving you a rough guess, not a real number.
Here are the key factors that affect sewage treatment plant cost in India:
| Plant Capacity | Approximate Cost Range |
|---|---|
| 1 KLD | Rs. 4.5 Lakh to Rs. 6 Lakh |
| 10 KLD | Rs. 8 Lakh to Rs. 15 Lakh |
| 25 KLD | Rs. 18 Lakh to Rs. 30 Lakh |
| 50 KLD | Rs. 30 Lakh to Rs. 55 Lakh |
| 100 KLD | Rs. 55 Lakh to Rs. 1 Crore |
1. Technology Selection
MBBR plants are generally more economical than MBR systems. MBR costs more because of the membrane modules. SBR falls in the middle range. Your treatment goal and output quality requirement will decide which technology makes sense.
2. Plant Capacity
Larger capacity plants cost more in absolute terms but cost less per KLD. A 100 KLD plant does not cost ten times a 10 KLD plant. There is an economy of scale as capacity increases.
3. Civil Work
If you need full civil construction including RCC tanks, the total project cost goes up. Packaged plants with pre-fabricated MS or FRP tanks cost less on civil but may have higher equipment cost.
4. Reuse Requirement
If you only need basic treated water for irrigation, a standard MBBR or SBR system is sufficient. If you need MBR-quality water for toilet flushing or cooling tower reuse, the plant design and cost changes accordingly.
CPCB Compliance and Water Reuse Benefits of Sewage Treatment Plants
Every sewage treatment plant we install is made to follow the rules set by the Central Pollution Control Board. The Central Pollution Control Board decides how clean the water has to be before we can put it back into rivers or use it again on the site.
If we do not follow these rules we can get in trouble. We might have to pay a lot of money or even get closed down. The State Pollution Control Board can also take us to court. That is why our plants are designed to meet these rules from the beginning so you do not have to worry.
Treated Water Reuse Applications
A good sewage treatment plant does more than just follow the rules. It also gives you water that you can use again. Here are some ways we use the treated water from our plants:
. We use it for toilets in buildings and apartments.
. We use it to water plants and gardens.
. We use it to fill up cooling towers.
. We use it to wash cars.
. We use it for construction work.
. We use it to water crops in the areas.
Sustainability Benefits
Every drop of water we clean and reuse is one we do not need to take from elsewhere. For schools and factories this can save a lot of money on water bills. It also helps reduce stress on the sewage system and rivers. Every litre of wastewater that we treat and reuse is one litre of water that we do not consume. This is a help to the environment and it saves you money too.
