Water Treatment Process from Reservoir to your Home

We take the water coming from our taps for granted, but do you know what happens before it gets to your home?

We take for granted the water that comes out of the taps in our home when we turn them on – but a lot of work goes into getting it there. Chemistry, too, has a hand in making sure that the water is safe to drink

The water that ends up in our homes can begin in a number of places. Much of it is groundwater – water beneath the Earth’s surface, trapped between the pores and cracks in rocks. This water can actually be relatively pure, due to natural filtration through chalk and similar rock types, and as such can sometimes skip through some of the treatment steps Water from reservoirs or rivers, on the other hand, will need these to be removed before further chemical treatment can begin.

Water Treatment Process

Screening

Screening helps to remove large matter from the water such as leaves and rubbish using a wire mesh. This prevents debris from causing obstructions within the facility making treatment easier

Coagulants Added

Coagulants such as aluminum sulfate and ferric chloride are mixed into the water. This makes particles of dirt and dissolved substances in the water clump together so they can be removed.

Water Treatment

Sedimentation

Under slow mixing, the clumped particles increase in size. Most of them sink to the bottom turning into sludge which can be removed from the water, treated and disposed of.

Filtration

Some particles remain in the water after sedimentation, these are removed by filtration through coal, sand and gravel beds. They are cleaned by pumping air and water backwards through them

pH Correction

Water that is too acidic can lead to water pipe corrosion. It can be passed through a filter containing crushed limestone to raise pH. Acids can be added if the pH is too high.

Anti Corrosion Agents

Agents such as orthophosphates can be added to the water in areas with lead pipes. These agents form lead-phosphates on the inside of the pipes and stop lead from getting into the water.

Chlorination

Chlorine is added to water to kill bacteria and viruses, preventing water-borne diseases such as Cholera and typhoid. Ozone can be used instead of chlorine, and avoids disinfection byproducts.

Home

Residual Chlorine in the water safeguards against pathogens.

After all of this, the water is finally free to leave and make its way to you – something to think about the next time you turn on the tap!
