Sewage Treatment Plants
Built on data. Backed by discipline. Designed to last
STPs look good on paper.
In the real world they smell, fail and
become dead assets.
At Inovar we design STPs for the conditions, and not for costs.
At Inovar we design STPs for the
conditions, and not for costs.
Every STP we build is driven by real data not assumptions. We test the Sewage samples, map load patterns, factor seasonal variations and much more. Inovar is a leading sewage treatment plant manufacturer. The STPs we will build are efficient, robust and durable.
From pumps to panels, every component is selected to keep your OpEX low.

Frequently Asked Questions
What is a Sewage Treatment Plant (STP)?
Why is treating sewage so important?
Untreated sewage is a major source of environmental pollution and public health hazards. Proper treatment:
• Protects Public Health: Eliminates pathogenic bacteria, viruses, and parasites.
• Safeguards the Environment: Prevents the pollution of rivers, lakes, and groundwater, protecting aquatic ecosystems.
• Conserves Water: Produces high-quality treated water that can be reused for non-potable purposes, reducing freshwater demand.
• Ensures Regulatory Compliance: Helps industries and municipalities comply with local and national environmental laws
What are the main stages of sewage treatment?
Sewage treatment typically occurs in three stages:
• Primary Treatment: Physical processes like screening and sedimentation to remove large solids and grit.
• Secondary Treatment: Biological processes where microorganisms consume dissolved organic pollutants. Common technologies include Activated Sludge Process (ASP), Moving Bed Biofilm Reactors (MBBR), and Sequential Batch Reactors (SBR)
• Tertiary Treatment: Advanced polishing steps to further disinfect and remove specific contaminants. This can include filtration (Sand, Activated Carbon), UV Disinfection, and Reverse Osmosis (RO) to produce high- quality reusable water.
What STP technology is best for my project?
There is no single “best” technology. The optimal choice for your project depends on several factors, including
• Influent Characteristics: The quantity and quality of incoming sewage (e.g., organic load, presence of industrial waste).
• Discharge/Reuse Standards: The required quality of the final treated water (e.g., for garden irrigation, toilet flushing, or surface discharge).
• Available Space: Some technologies like SBRs have a smaller footprint than conventional ASP.
• Capital and Operational Expenditure (CAPEX & OPEX): Your budget for construction and long-term operation.
• Operator Skill Level: Some systems are more automated and easier to operate than others.
Inovar’s engineers will conduct a detailed feasibility study to recommend the most efficient and cost- effective technology for your specific needs.
How is the capacity (size) of an STP determined?
The capacity is determined based on the Average Daily Flow and Peak Flow of wastewater expected. We calculate this using factors like:
• Population Equivalent (PE): For residential projects.
• Water Consumption Data: For commercial and industrial complexes.
• Local Building Codes and Standards.
• Designing for peak flow ensures the plant can handle times of maximum usage without failure.
Can you design an STP for a site with limited space?
What is the difference between an MBBR, SBR and MBR?
• MBBR (Moving Bed Biofilm Reactor): Uses thousands of small plastic carriers (media) that move freely in the water, providing a surface for bacteria to grow. It’s efficient, robust, and handles load variations well.
• SBR (Sequential Batch Reactor): Treats wastewater in batches in a single tank. It performs all treatment stages (aeration, settling, decanting) in a time-controlled sequence. It offers excellent control and a compact footprint.
• MBR (Membrane Bioreactor): Combines biological treatment with membrane filtration (like ultrafiltration). It produces the highest quality effluent in a very compact space but has higher capital and membrane replacement costs.
What services does Inovar Engineering and Consultants provide?
Inovar offers end-to-end solutions under one roof:
• Feasibility Study & Detailed Project Report (DPR)
• Concept & Detailed Design Engineering
• Technology Selection & Sourcing
• Turnkey EPC (Engineering, Procurement, and Construction)
• Civil & Structural Works
• Installation, Commissioning, and Startup
• Operation & Maintenance (O&M) Contracts
• Performance Audits and Plant Upgradation
Do you handle the necessary permits and regulatory approvals?
What are the key cost factors for an STP?
The total cost depends on:
• Plant Capacity & Technology: Larger plants and advanced technologies (like MBR) cost more.
• Effluent Quality Requirements: Stricter reuse standards require more advanced tertiary treatment, increasing cost.
• Civil Works: Site conditions and land preparation costs.
• Electromechanical Equipment: Quality and origin of pumps, blowers, and controls.
• Labor & Energy Costs: For ongoing operation.
What happens to the sludge produced during treatment?
The sludge is a by-product rich in organic matter. It can be:
• Thickened and Dewatered using centrifuges or filter presses.
• Treated Anaerobically in a biogas plant to produce renewable energy (methane).
• Composted to create a valuable, nutrient-rich soil conditioner (manure).
• Safely disposed of in accordance with environmental regulations.
What can the treated water from an STP be used for?
Treated sewage water, or reclaimed water, is perfect for non-potable applications such as:
• Landscape and agricultural irrigation
• Cooling tower makeup water
• Toilet and urinal flushing
• Vehicle washing
• Construction activities
• Floor and carpet cleaning
