Steps of How the Water Gets Cleaned<br />
11<br />
The person that we interviewed<br />
is Allen Wu who is part of the Walnut<br />
Valley Water District. The water<br />
depends on the population. One<br />
person can equal up to 120 gallons<br />
of water. He told us the steps of water<br />
going through the cleaning process.<br />
1) Filter the water like a big screen<br />
will keep out the big molecules.<br />
2) Add chemicals to the addition of<br />
chemicals to the water to be treated.<br />
3) The water will be pumped through one of many different<br />
types of filters, leaving the accumulated floc behind in the<br />
filtration media.<br />
4) Pump into a closed tank<br />
where disinfectant chemicals<br />
such as chlorine are used to<br />
destroy any bacteria or other<br />
microorganisms that might<br />
have survived the filtration<br />
process.<br />
