Drishti Enviro Engineers Pvt. Ltd. has successfully installed a 750 KLD Underground Sewage Treatment Plant (STP) based on conventional MBBR technology in Ludhiana, Punjab.
Designed to treat up to 750,000 litres of sewage per day, this large-capacity underground STP combines a proven biological treatment process with an underground configuration, helping meet wastewater treatment requirements while making efficient use of available site space.
This project demonstrates our capability to design and execute large-capacity STP projects in Ludhiana according to actual site conditions, wastewater generation and project requirements

Why MBBR Technology for Sewage Treatment?
MBBR (Moving Bed Biofilm Reactor) is a biological wastewater treatment process in which specially designed carrier media provides surface area for microorganisms to grow as biofilm.

During biological treatment, microorganisms growing on the media help break down biodegradable organic matter present in the wastewater.
MBBR technology is widely used in sewage treatment because it can provide:
- Effective biological treatment
- High surface area for microbial growth
- Compact biological treatment configuration
- Stable treatment performance when properly designed and operated
- Suitability for different STP capacities
- Integration with conventional sewage treatment stages
For this 750 KLD STP in Ludhiana, MBBR forms an important part of the biological treatment process.
750 KLD Means 7.5 Lakh Litres of Sewage Per Day
The capacity of an STP is commonly expressed in KLD – Kilolitres per Day.

Applications of Large-Capacity MBBR STPs
MBBR-based STPs can be designed for different project types and capacities.
Large-capacity systems such as this 750 KLD STP may be suitable, subject to wastewater generation and project requirements, for:
- Large residential societies
- Group housing projects
- Townships
- Commercial developments
- Hotels and resorts
- Hospitals
- Educational institutions
- Industrial developments
- Infrastructure projects
Plant capacity should always be selected based on actual or projected sewage generation rather than simply choosing a standard STP size.

Major Components of the Underground STP
The actual configuration of an STP depends on its approved process design. A conventional MBBR-based STP can incorporate various civil, mechanical and electrical components, including:
- Underground treatment tanks
- Screening arrangements
- Equalization system
- MBBR biological treatment system
- MBBR carrier media
- Air blowers
- Diffused aeration system
- Pumps
- Clarification system
- Filtration units
- Piping and valves
- Electrical control panels
- Treated-water handling system
The equipment is selected and sized according to the required capacity and treatment process.
Frequently Asked Questions
What is the capacity of this underground STP in Ludhiana?
The installed STP has a treatment capacity of 750 KLD, equivalent to up to 750,000 litres or 7.5 lakh litres of sewage per day under its designed operating conditions.
Which technology is used in the 750 KLD STP?
The project uses a conventional MBBR (Moving Bed Biofilm Reactor) based sewage treatment process.
Is the 750 KLD STP installed underground?
Yes. The 750 KLD STP has been installed underground in Ludhiana, Punjab.
What is an MBBR STP?
An MBBR STP uses moving carrier media inside the biological reactor. Microorganisms grow as biofilm on this media and help biologically degrade organic pollutants in sewage.
What are the benefits of an underground STP?
An underground STP can help utilize available site space efficiently by accommodating major treatment infrastructure below ground, subject to the project’s structural, operational and site requirements.
