Sewage Treatment Plants Using Sunlight and Soil for Sustainable Wastewater Management

Sewage treatment plant is about resource recovery and the future is about extracting materials from wastewater that can be used again and again.


Biodegradation of organic carbon or BOD in rejuWATER Sewage Treatment Plants

rejuWATER sewage treatment plants are designed so that someone's waste becomes food for another life form. The growRITE soil in STP metabolizes wastewater using heterotrophic or carbonaceous bacteria. 

A bioconversion process through ingestion, respiration, and growth recycles nutrients in sewage to feed reed plants planted in the soil. In return, plants use soil nutrients and photosynthesis to supply dissolved oxygen (DO) to soil and water.

rejuWATER sewage treatment plant modules operate symbiotically without any external power source.


rejuWATER domestic grey water treatment plant

Despite the grey water treatment plant's ability to treat all waters except sewage, the rejuWATER grey water treatment plant can handle domestic sewage as well. Domestic sewage is largely composed of organic carbon, either in solution or as particulates. 

Proteins, amino acids, peptides, carbohydrates, fats and fatty acids make up the bulk of organic matter, which can be easily decomposed. Bacteria eat small organic carbon molecules. In this way, the bacteria multiply and the wastewater is purified.

The treated wastewater can be used for flushing and gardening.


rejuWATER zero liquid discharge system

Wastewater from industries, agriculture, and municipalities is generally returned to the environment without being treated. 

The concept of the treatment process is quite simple, but the control of the treatment process in a conventional sewage treatment plant to achieve zero liquid discharge is very complex due to the large number of variables that can impact it. These include several fluctuations like, flow rates, food to microbe ratio, pH, temperature etc.


The rejuwater zero liquid discharge system aims to improve the consistency of treatment despite the fluctuations.


rejuWATER Faecal Sludge Treatment Plant (FSTP)

rejuWATER Faecal Sludge Treatment Plant recycles scum, effluent and sludge through natural treatment. It can be easily designed as a treatment option that is adapted to the specific region. rejuWATER FSTP dewaters and bioconverts faecal sludge (septage) and composts with solid waste to improve soil fertility.

The rejuWATER FSTP offers a replicable, scalable, environmentally friendly, and cost-effective solution for efficient faecal sludge management in rural and urban areas. They have low operational and maintenance costs. The humus rich compost can be used as a soil conditioner.

Frequently asked questions

Which Sewage treatment plants are the best?

Ideally, any sewage treatment plants that provides high-quality treated water without wasting a lot of energy or requiring skilled labor. These STPs would reduce your freshwater footprint by 50 to 70%.

How do I choose the best wastewater treatment plant?

Traditionally, a household consists of five members. Home sewage has a Biochemical Oxygen Demand (BOD) of 300 to 600 mg/L, which makes it relatively easy to recycle. Ideally, the STP should be able to effectively recycle wastewater from kitchen sinks and toilets for flushing and gardening. A machine that uses a lot of electricity or requires a lot of maintenance is not something you want.

What is the cost of running a STP plant?

The traditional electromechanical STP plants require air to be blown 24 hours a day, 365 days a year into an aeration tank where bacteria are grown to digest organic waste.It consumes a lot of energy. The cost of operating an electromechanical STP for 100 KLD is typically ₹200,000/month. rejuWATER STP reduces this cost to less than ₹50,000/-.

Where is the best place to build a sewage treatment plant?

Wastewater treatment plants are situated at the lowest point on a property so that all wastewater can be transported there by gravity. The sewage is stored in raw sewage storage tanks until it can be treated. Older properties that don't have STP may have septic tanks or soak pits.

How do Sewage Treatment Plants Work?

rejuWATER, Sewage treatment plant from RITEWAYS, works by breaking down waste and feeding it to plants, which then feed the soil with oxygen. During bio conversation, some oxygen is consumed and the rest becomes part of the treated water. Since rejuWATER, Wastewater treatment plant is a robust design, it has a higher level of reliability. The module capacity is 3KLD (3000 liters per day). The treated water is high-quality and consistent. rejuWATER, STP treated water can be used for gardening, cleaning, flushing, cultivation, and other uses.

What is rejuWATER sewage treatment plant?

rejuWATER sewage treatment plant is an ecosystem where someone's waste becomes other's food. The microlife in growRITE® STP soil bioconverts human waste in water. The bioconversion process breaks down the sewage to feed reed plants planted in the soil. Plants use soil nutrients and photosynthesis to provide dissolved oxygen (DO) to soil and water. rejuWATER modules function symbiotically without any external power source.

Industries served by rejuWATER STP Plant

Our STP plants have been successfully deployed in various residential and commercial projects. rejuWATER sewage treatment plants can be used for domestic applications like individual homes, marriage halls, apartments, places of worship, hostels, and old age homes.


rejuWATER effluent treatment plants (ETP's) can be used in hotels, clubs, resorts, car wash centers, dairy farming, fishing industry, food processing industry, agro farms, sugar industry, etc..
