Designing an On-site Disposal System That Allows Water Recycling

Modern urban water recycling plant

A lot of water is wasted in sinks, toilets, baths, basins and showers. One option to cut down on wastes is to recycle wastewater. If you do not have access to a conventional sewer, you should consider recycling your wastewater by designing an on-site disposal system suited for water reuse.

Separate black water from the grey water

Well-designed sewage systems for rural areas simplify the wastewater treatment process. They separate the black water from the grey water right at its source. This separation minimises the amount of wastewater with emulsified grease, solids and grit, reducing disposal system failures and allows quick reuse of grey water.

Consider intended use when collecting grey water

Grey water is potable water from sources such as baths, showers, washing machines, and basins. Although the water may be slightly contaminated, it can be used to flush toilets, water gardens, or wash cars. How you intend to use this water should determine the detail and extent of your collection system.

Do not keep untreatedgrey water for long

Grey water should be returned to the environment as soon as possible, especially if it is untreated. If you store it untreated, the bacteria in the water will begin to break down the available nutrients leading tobadodours and deterioration of water quality.

Combine treated black water with the treatedgrey water for final disposal

Blackwater refers to the liquid waste from toilets and sometimes the kitchen sinks. After thorough treatment, the previously unsanitary water can be recombined with the filtered grey water. You can now dispose the water into the soil through trenches, drip lines or any other site-specific disposal system.

The pressure on water resources continues to rise. You should embrace any chance you get to reuse or recycle water. You can design your on-site disposal system in a way that maximises how you reuse and recycle this valuable resource.
