Sewage Treatment Plant
Sewage Treatment Plant (STP) Solutions by Varuna
With rapid urbanization and increasing water scarcity, managing wastewater responsibly has become more critical than ever. At Varuna, we offer robust and scalable Sewage Treatment Plant (STP) solutions that help residential, commercial, and institutional spaces meet their environmental responsibilities, reduce water wastage, and comply with statutory discharge norms.
Why STP Systems Are Essential Today
Whether it’s an apartment complex, a hospital, a hotel, or an industrial facility—every entity generates a significant amount of domestic wastewater every day. An effective STP is crucial to:
-
Treat sewage water before disposal or reuse
-
Reduce the load on municipal sewage systems
-
Conserve freshwater by enabling treated water recycling
-
Ensure compliance with CPCB/SPCB discharge norms

What is a Decentralized STP?
A Decentralized Sewage Treatment Plant (Decentralized STP) is a small-scale treatment solution designed to treat wastewater at the source, instead of transporting it to a central treatment facility. It is ideal for locations where infrastructure is limited or centralized systems are unviable.
Applications of Decentralized STPs
-
Apartment buildings and housing societies
-
Commercial complexes and business parks
-
Schools, colleges, and universities
-
Remote locations and resorts
-
Government offices and institutional campuses
-
Villas, townships, and gated communities
Benefits of Decentralized STP Solutions
-
On-Site Treatment: Eliminates the need for external pipelines and reduces transportation cost
-
Space-Saving Modular Design: Easily integrates into tight urban spaces or retrofits
-
Cost-Efficient: Lower operational and maintenance costs compared to centralized systems
-
Faster Installation: Skid-mounted or plug-and-play systems install in days, not weeks
-
Reusable Treated Water: Use for landscaping, flushing, cooling towers, etc.
-
Compliance Assurance: CPCB/SPCB-compliant discharge levels guaranteed
How Our Modular STP Systems Work
-
Primary Treatment: Solid separation and sedimentation
-
Secondary Treatment: Biological processing (MBBR/SBR/MBR)
-
Tertiary Filtration: Sand filters, carbon filters, and UV or ozone disinfection
Treated water quality meets norms for reuse in non-potable applications.

Frequently Asked Questions (FAQs) about Sewage Treatment Plants by Varuna
-
What is a sewage treatment plant and why is it important for residential projects?
A Sewage Treatment Plant (STP) treats wastewater from toilets, kitchens, and bathrooms to remove contaminants before reuse or safe disposal. It's essential for apartments and housing societies to comply with pollution control board norms and reduce freshwater usage.
-
What is a decentralized STP and how is it different from a centralized system?
A Decentralized STP is a compact, site-specific sewage treatment solution designed to treat wastewater at the source. Unlike centralized systems, it eliminates the need for external pipelines and allows treatment even in remote or space-limited areas.
-
What are the benefits of installing a decentralized STP system at my property?
Decentralized STPs offer fast installation, low maintenance, space-saving design, and cost-effective operation. They're perfect for apartments, schools, villas, and commercial buildings lacking central sewage infrastructure.
-
Which STP technologies does Varuna offer for domestic and commercial use?
Varuna offers STPs based on SBR (Sequencing Batch Reactor), MBBR (Moving Bed Biofilm Reactor), and MBR (Membrane Bio-Reactor) technologies — all designed for high efficiency and CPCB compliance.
-
Is treated sewage water from Varuna’s STP systems safe for reuse?
Yes, our STPs deliver CPCB-compliant treated water, suitable for flushing, landscaping, cooling towers, and other non-potable uses — helping reduce your dependence on freshwater.
-
What is the installation time for a plug-and-play STP by Varuna?
Our modular STP systems can be installed in just 7–10 days, while precast RCC tank-based units are ready within 15 days, depending on site readiness.
-
Can Varuna customize STP capacity for different property sizes?
Absolutely. We offer customized STP solutions starting from 10 KLD to 500+ KLD, tailored to match your wastewater load and space availability.
-
How much space is required to install a decentralized STP system?
Our compact modular STPs are designed for space-constrained sites and require minimal civil work. The exact footprint depends on the treatment capacity required.
-
Is Varuna’s STP system compliant with PCB norms?
Yes, all Varuna STPs meet the latest CPCB and SPCB discharge norms, and we provide documentation and test reports to support environmental audits.
-
What kind of maintenance is required for Varuna’s STP units?
Our systems are designed for minimal maintenance. We also offer Annual Maintenance Contracts (AMC) for routine service, performance checks, and remote monitoring support.
With urbanisation on the rise, apartment complexes are generating substantial wastewater daily. A well-designed Sewage Treatment Plant (STP) is crucial for ensuring effective wastewater management, reducing environmental pollution, and conserving water resources. Choosing the best STP for apartments depends on factors such as capacity, efficiency, compliance with environmental regulations, and cost-effectiveness.
Our range of products includes Sewage Treatment Equipment, Domestic Packaged Sewage Treatment Plant, Capsule Packaged Sewage Treatment Plant 30 KLD, Industrial Sewage Treatment Plant, Sewage Treatment Plant Maintenance Services and STP Installation Service.
