Capacities of Grey Water Treatment Plants

Grey Water Treatment Plants are available in a wide range of capacities to meet the water recycling needs of residential, commercial, and industrial sectors. These systems can be designed in the following capacity ranges:

  • 5 KLD to 50 KLD, with some larger systems reaching up to 100 KLD (Common capacities: 10 KLD, 15 KLD, 20 KLD, 25 KLD, 30 KLD, 50 KLD, 75 KLD, 80 KLD, 100 KLD)

  • 1,000 LPH to 50,000 LPH, and advanced large-scale plants reaching up to 100,000 LPH for high-volume water recycling.

These capacities make GWTPs suitable for efficiently treating wastewater from bathrooms, laundry, kitchens, and other non-sewage sources.

Applications of Industrial Grey Water Treatment Plants (GWTP)

Grey Water Treatment Plants help recycle and reuse wastewater for non-potable needs, significantly reducing dependency on fresh water and lowering operating costs in various industries.

Commercial Buildings: Used in office complexes, malls, and corporate buildings to recycle grey water for toilet flushing, landscaping, and cleaning, reducing water bills and environmental impact.

Manufacturing Industries: Treats water from industrial washing, cooling, or cleaning processes and reuses it for non-potable applications, helping industries save water and reduce wastewater discharge.

Power Plants: Treated grey water is used for cooling towers, non-critical cleaning, and landscaping, minimizing the consumption of freshwater in power generation facilities.

Hotels & Resorts: Treats grey water from bathrooms, sinks, and laundry, which is then reused for gardening, toilet flushing, and general cleaning—making the facility more sustainable.

Food & Beverage Industry: Grey water from washing and cleaning processes can be treated and reused for floor washing, cooling systems, and landscaping to reduce water wastage.

Construction Sites: Treated grey water is useful for dust suppression, equipment cleaning, and site landscaping, reducing reliance on fresh water resources.

Textile Industry: Water from washing and rinsing fabrics is treated and reused in non-production processes such as cooling, cleaning, and floor washing, helping conserve water.

Frequently Asked Questions

A Grey Water Treatment Plant is a system designed to treat and recycle grey water — wastewater generated from showers, sinks, laundry, and other non-toilet sources. It removes contaminants so the water can be reused for non-potable purposes, reducing freshwater consumption.

  • Reduces freshwater usage

  • Lowers water bills

  • Supports sustainable water management

  • Enables reuse of treated water for flushing, gardening, cooling, etc.

  • Overall, it helps conserve water and protect the environment.

A typical GWTP includes several stages:

  1. Pre-treatment: Removes debris and large solids.

  2. Primary treatment: Settles out bigger particles.

  3. Secondary (biological) treatment: Reduces organic matter biologically.

  4. Tertiary treatment: Advanced filtration and disinfection to polish the water.

  5. Storage & distribution: Clean water is stored for reuse.

Treated grey water can be reused for:

  • Toilet flushing

  • Landscaping or gardening

  • Cooling towers

  • Cleaning or washing non-food surfaces
    This reuse helps cut fresh water demand.

Yes — treated grey water can be used for irrigation, garden watering, and landscaping, provided the system includes appropriate filtration and disinfection to remove contaminants.
