Description
Introduction to 100 KLD Sewage Treatment Plant
A 100 KLD Sewage Treatment Plant (STP) is a wastewater treatment system designed to treat approximately 100,000 litres of domestic sewage per day under its specified design conditions. It is commonly suitable for large apartment complexes, housing societies, hotels, resorts, hospitals, schools, colleges, commercial buildings, institutions, townships and other developments generating substantial quantities of domestic wastewater.
With rapid urbanization and increasing water demand, proper sewage treatment has become an important part of modern infrastructure. Untreated domestic wastewater can cause unpleasant odours, sanitation problems and environmental pollution and can negatively affect nearby land and water resources.
A properly engineered 100 KLD STP plant provides a systematic approach to collecting, treating and managing domestic sewage. Depending on the selected treatment technology and treated-water requirements, the treated water can potentially be reused for non-potable applications such as gardening, landscaping, toilet flushing and floor cleaning.
V AQUA WATER TREATMENT COMPANY provides water and wastewater treatment solutions designed according to project capacity, wastewater characteristics, available space, treatment objectives and intended water reuse.
What Does 100 KLD Mean in an STP Plant?
KLD stands for Kilolitres per Day.
Therefore:
- 1 KLD = 1,000 litres per day
- 100 KLD = 100,000 litres per day
- 100 KLD = 1 lakh litres per day
A 100 KLD sewage treatment plant has a nominal treatment capacity of approximately 100,000 litres of sewage per day, subject to its design and operating conditions.
The required plant capacity should be determined using actual or estimated wastewater generation rather than relying only on building size or population.
Important design parameters include:
- Number of occupants
- Average water consumption
- Sewage generation
- Peak wastewater flow
- Wastewater characteristics
- Hydraulic loading
- Organic loading
- Required treated-water quality
- Water-reuse requirements
- Future expansion
- Available installation area
Proper process and hydraulic design are essential for stable plant performance.
Why Is a 100 KLD Sewage Treatment Plant Required?
Domestic sewage contains organic matter, suspended solids, nutrients, microorganisms and other contaminants. If sewage is discharged without adequate treatment, it can contribute to water and land pollution and create unhygienic conditions.
A 100 KLD sewage treatment plant manufacturer designs the system to reduce these pollutants using appropriate physical, biological and tertiary treatment processes.
Major reasons for installing a 100 KLD STP include:
- Effective domestic wastewater treatment
- Environmental protection
- Better sanitation
- Reduction of suspended solids
- Reduction of biodegradable organic matter
- Supporting wastewater recycling
- Reducing freshwater consumption
- Improved water management
- Supporting applicable project requirements
For large residential and commercial developments, an on-site STP can become an important component of sustainable water management.
How Does a 100 KLD STP Plant Work?
The exact treatment process depends on the selected technology, wastewater characteristics and treated-water requirements.
A typical 100 KLD sewage treatment plant may include the following stages.
1. Screening and Preliminary Treatment
Raw sewage enters the plant through an inlet screening system.
Screening removes larger materials such as:
- Plastic
- Paper
- Cloth
- Packaging waste
- Floating debris
This protects pumps, pipelines, valves and downstream treatment equipment.
2. Equalization of Wastewater Flow
The wastewater then enters an equalization tank where variations in flow and pollutant loading can be balanced.
Sewage generation is generally not constant throughout the day. Equalization can help maintain a more stable flow to the biological treatment stage.
3. Primary Treatment
Primary treatment is designed to remove settleable solids and heavier suspended matter.
Depending on the selected process, this may involve a settling tank or another primary-treatment arrangement.
4. Biological Treatment
Biological treatment is one of the most important stages in sewage treatment.
Microorganisms consume biodegradable organic matter present in wastewater.
Common biological treatment technologies include:
- MBBR
- SBR
- MBR
- Activated Sludge Process
- Extended Aeration
- Other customized biological processes
The appropriate technology should be selected according to wastewater characteristics, space availability, treated-water quality and operating requirements.
5. Secondary Clarification
After biological treatment, the wastewater may pass through a secondary clarification stage.
The clarifier separates biological solids from the treated wastewater. Depending on the process, settled sludge can be returned to the biological stage, while excess sludge is removed for appropriate management.
6. Tertiary Treatment and Filtration
Additional filtration can be provided where higher-quality treated water is required.
Typical tertiary-treatment systems include:
- Pressure Sand Filter
- Activated Carbon Filter
- Micron Filter
- Ultrafiltration
- Other polishing systems
The filtration configuration should be selected according to the intended reuse application.
7. Disinfection
Disinfection is used to reduce microbial contamination in treated wastewater.
Possible methods include:
- Chlorination
- Sodium hypochlorite dosing
- UV disinfection
The appropriate disinfection system depends on the final water-quality requirements.
8. Treated-Water Storage and Reuse
After treatment, filtration and disinfection, treated water can be transferred to a storage tank.
Depending on its quality and applicable requirements, it may potentially be reused for:
- Gardening
- Landscaping
- Toilet flushing
- Floor washing
- Road cleaning
- Other suitable non-potable applications

Installation & Project Execution
The prefabricated STP installation at Greater Noida facility was carried out through a planned sequence of activities, beginning with site preparation and continuing through equipment installation, utility connections, testing, and final commissioning. The prefabricated design helped streamline on-site execution by allowing a significant portion of the treatment system to be fabricated and assembled before delivery.
| Execution Stage | Work Description |
|---|---|
| Site Preparation | The designated installation area was prepared and the foundation/base was made ready to support and accommodate the prefabricated STP unit. |
| STP Unit Placement | The fabricated treatment unit was delivered to the facility, carefully positioned at the specified location, and properly aligned on the prepared foundation. |
| Mechanical Installation | Required mechanical components and treatment equipment were installed, connected, and integrated with the prefabricated treatment system. |
| Piping & Interconnections | The sewage inlet, internal process connections, interconnecting pipelines, and treated-water outlet were connected to establish the complete treatment flow path. |
| Electrical & Control Integration | Electrical cabling, control panels, instrumentation, and associated connections were completed and integrated with the operating equipment. |
| Testing & Commissioning | The completed system was inspected and tested for proper operation, pipeline integrity, equipment performance, and control functionality before commissioning and trial operation. |
The stage-wise installation methodology demonstrates one of the key benefits of prefabricated sewage treatment systems. Since substantial fabrication and assembly can be completed off-site, the amount of civil and installation work required at the project location can be reduced. On-site activities can therefore concentrate primarily on unit placement, mechanical and electrical connections, piping integration, testing, and commissioning, helping create a more organized project execution process.
Treated Water Management & Ground Discharge/Recharge
An important part of the project is the management of the treated water produced after sewage treatment. The overall process begins with the collection of sewage from the facility, followed by treatment through the STP. After treatment, the treated effluent is monitored for the required quality parameters before being directed toward the designated discharge or recharge arrangement applicable to the site.
The terms ground discharge and groundwater recharge should not be considered interchangeable. Ground discharge generally refers to releasing treated water at an approved or designated location on the premises or through an authorized disposal arrangement. Groundwater recharge, on the other hand, specifically involves directing suitable water into the ground with the objective of replenishing groundwater resources.
The appropriate method depends on the site’s engineering arrangement, treated-water quality, applicable environmental requirements, and permissions or conditions imposed by the relevant authorities. Therefore, the installation of an STP alone should not be interpreted as automatic authorization for groundwater recharge.
Effective sewage treatment is essential before any permitted discharge or reuse activity because it helps reduce the pollutant concentration and environmental impact associated with untreated wastewater. However, the suitability of treated water for a particular application must be established through quality monitoring, applicable standards, site-specific requirements, and regulatory approvals.
The treated-water management approach at the company facility can be summarized as follows:
- Sewage is treated through the installed prefabricated STP before discharge or further application.
- Treated effluent quality is monitored as part of the plant’s operational management.
- The treated water is directed toward the designated ground discharge/recharge arrangement applicable to the facility.
- Treatment and discharge practices are carried out with consideration of applicable environmental and regulatory requirements.
- The final use or disposal of treated water remains subject to site conditions, permitted arrangements, and relevant regulatory provisions.
Environmental Benefits of the Project
The installation of a dedicated sewage treatment facility at company Greater Noida location strengthens the site’s overall wastewater management infrastructure and supports responsible environmental practices.
Key environmental benefits include:
- Reduction in untreated sewage discharge: The STP provides a dedicated treatment process before wastewater is released through the designated route.
- Lower wastewater pollution load: Treatment helps reduce the concentration of pollutants present in domestic sewage.
- Improved wastewater management: A dedicated treatment system enables wastewater handling to follow a more controlled and systematic process.
- Support for sustainable water management: Proper treatment creates opportunities for responsible disposal or reuse of treated water, where permitted.
- More responsible effluent handling: Treated wastewater can be managed according to the designated site-specific discharge or recharge arrangement.
- Environmental compliance support: The treatment infrastructure assists the facility in meeting applicable wastewater management and environmental requirements.
- Enhanced treatment infrastructure: The prefabricated STP adds a structured and dedicated sewage treatment solution to the facility’s existing infrastructure.
Overall, the project demonstrates how a prefabricated STP can provide a practical and organized approach to sewage treatment, combining streamlined installation with controlled wastewater management and improved environmental performance at an industrial facility.
