Home Sewage Treatment Plant

A home sewage treatment plant is used to treat domestic wastewater. The wastewater includes greywater and blackwater generated in a home. Greywater is the water that is produced by showers, baths, washing machines, sinks and basins. This is the best water for recycling as there aren’t any additives.

Blackwater is the water that comes from the waste pipe of your toilet. This water contains a lot of infectious agents and can be broken down to be recycled to a smaller extent than greywater.

Sewage Treatment Plant Installations and Maintenance

Each block has unique natural features and each home will have different water usage habits which could make one style ideal and another unsuitable. Express Wastewater take pride in customising the water treatment option for each customer, carefully matching the right system with the right property.

How does a Sewage Treatment Plant work?

A sewage treatment plant combines blackwater and greywater which is then processed using natural bacteria and other additives. The result is recycled water that can be used around the home and garden.

Through a series of chemical processes, a sewage treatment plant looks after the wastewater that is typically generated by a home. The treatment is done in three stages.

Stage 1 - The heavier solids settle at the bottom of the tank and the lighter materials float to the surface. The middle layer flows to the second chamber wherein it is treated by the anaerobic bacteria. The effluent or the middle layer flows into the second chamber where it is broken down by anaerobic bacteria.

Stage 2 - Air is added to the liquid waste in the second stage. The dissolved oxygen increases in the water and is used by bacteria to consume the pollutants. Aerobic bacteria can multiply faster in water and eats pollutants faster than anaerobic bacteria.

Stage 3 - Wastewater becomes lighter and cleaner than what it was when it entered the system as a sludge. Ultraviolet light or chlorine is used to disinfect the wastewater and it is then reintroduced into the environment. The treated water can be used for irrigation without any concern for polluting the environment or affecting your health.

How much does a sewage treatment plant cost?

There is no one-size-fits-all wastewater treatment system, each block has unique natural features and each home will have different water usage habits which could make one style ideal and another unsuitable.

This is why we offer a free 30 minute consultation between you and our wastewater experts to help determine which sewage treatment plant is right for your home or whether it would be more beneficial to keep your existing system.

Express Wastewater take pride in customising the water treatment option for each customer, carefully matching the right system with the right property. Find out more about the installation and running costs of the different options - Sewage Treatment System Price Guide
