Sewage treatment and reuse is a smart approach to satisfy a sizable portion of your water needs, if you live in a standalone home. Wastewater in this context only refers to greywater, or the water from washing machines and bathroom sinks, etc.

Let’s see how sewage is handled at home!

Importance of treating greywater

Greywater, or water from kitchens, is easier to treat and reuse than blackwater, because it contains less organic matter and is significantly less pathogenic.A typical household produces about 40% of its wastewater as greywater, which contains impurities including soap, detergent, dead skin, hair, and grease. This water can be used for flushing toilets and gardening after treatment.

Up to 40% of home water needs can be satisfied by it. But, it's vital to keep in mind that this water is not fit for drinking; and to make it potable, additional treatments like ozonation are reverse osmosis are required.

Treatment of greywater at home

Greywater treatment can be done using a variety of techniques. The one we're talking about uses a reed bed, or planted gravel filter, as a natural treatment method. It can be set up in the area surrounding your home. Overall, this technique offers substantial long-term savings.

Only 50–75 square feet in the plot will be occupied by the treatment system. Since, the water runs through the system by gravity and does not need to be pumped, there is no need for electricity.

The mechanism holds water for 60 to 72 hours. Based on the household's water consumption and wastewater production, the system should be developed according to standards. To determine where the system should be installed, it is best to get professional advice.

How to Construct a greywater natural treatment system?

The system's components are:

1: Grease trap and inspection chamber

2: Blocker filter

3: Storage tank with a reed bed and planted gravel filter

·         Grease trap/inspection chamber

The water is brought to the examination room by pipes carrying greywater from various home appliances, such as the washing machine and bathtub. Only the water moves on to the next step, the baffle filter, as the floating solids are held back by a baffle wall.

·         Baffle filter

Water runs through a baffle filter, which consists of a filter and several baffle chambers. Water is treated by anaerobic decomposition as it passes through the baffle chambers, which helps to clear away debris and scum.

·         Reed bed and planted gravel filter

Wetland plants are rooted in reed beds, which are gravel-filled containers.

Here, water is cleaned as follows:

Plants absorb nutrients from the water, including manufactured substances like soap. This promotes plant development as well because wetlands plants grow hydroponically, or by utilizing only water and its nutrients.

Natural die-off, antibiotics generated by plant roots, UV exposure, sedimentation, and pathogens, adhering to the gravel bed all kill pathogens in water.A reed bed with a surface area of 5-7 sqm and a depth of 1-1.5 m is advised for every 1000 litres of greywater.

·         Holding tank

In the holding tank or polishing pond, treated wastewater is dumped. At this point:

·         Water's dissolved oxygen content rises.

·         There arefewer odours.

·         Any contaminants that remain are oxidized.

·         UV exposure eliminates pathogens.

Conclusion

Toilets can be flushed with treated wastewater, but a dual plumbing system would need to be installed to get the water back into the house. The treated water can also be utilized for gardening.
