Because of the demand of potable water, you can find many hydraulicresources. That means that when you want to get it we find ourselves in a world of possibilities.
We are going to talk about the most common process.

Observation: humanity needs potable water to survive, and not everybody can have it easily, so we need to transform non-potable water into potable water.

Hypothesis: we can get potable water by using some treatments on non-potable water by following a process.
NON-POTABLE WATER POTABLE WATER
The process follows these steps…

-Water
catchment:
we take water from natural resources, usually rivers.

-Diversion of water:We take water from the natural resources to a water treatment plant by using twodifferent methods:
-Water conveyance: we use the gravity to transport water, because the natural resource is higher than the water treatment plant.
-Water impulsion: if the natural resource is lower than the water treatment plant, we use bombs.
This is how the romans did it
(Water conveyance)

-Flocculation:we eliminate the particles in suspension with some chemical agents.
Particles join together and become heavier, allowing the water to clear.

-Decantation:water is placed on a sink and liquids separate because of its weight.
![Page 9: By Carlota de Novales, Saray Ortega, Marta Fuentes, José ......Observation: humanity needs potable water to survive, and not everybody can have it easily, so we need to transform](https://reader034.fdocuments.net/reader034/viewer/2022042621/5f4e011dc5ec24719c5c2665/html5/thumbnails/9.jpg)
-Filtration:water and materia in suspension separate by pouring the water through a porous element, usually sand. The result is clearer water, because 95% of the organisms
have been eliminated.

-Chlorination:microbial agents are destroyed with different chemical products (usually chlorine).

-Alkalizing:because of water’s coagulant, it becomes acid, so we must add lime for it to
be potable.

-Distribution:once the water is potable, it’s carried to pump stations where it is distributed thanks
to the pipe network.

Water can be purified by using some treatments
![Page 14: By Carlota de Novales, Saray Ortega, Marta Fuentes, José ......Observation: humanity needs potable water to survive, and not everybody can have it easily, so we need to transform](https://reader034.fdocuments.net/reader034/viewer/2022042621/5f4e011dc5ec24719c5c2665/html5/thumbnails/14.jpg)
1.Flocculation.
2.Decantation.
3.Filtration.
4.Chlorination.
5.Alkalizing.

Now we are going to talk about water purification in Andalusia.
![Page 16: By Carlota de Novales, Saray Ortega, Marta Fuentes, José ......Observation: humanity needs potable water to survive, and not everybody can have it easily, so we need to transform](https://reader034.fdocuments.net/reader034/viewer/2022042621/5f4e011dc5ec24719c5c2665/html5/thumbnails/16.jpg)
It provides water to:
-Alcalá de Guadaira. -Alcalá del Río.
-Camas. -Coria del Río.
-Dos Hermanas. -La Puebla del Río.
-La Rinconada. -Mairena del Alcor.
-San Juan de Aznalfarache. -Sevilla.
TREATMENT CAPACITY: 10 m3/second.
STORE CAPACITY: 266,000 m3.

In Andalusia 547,493
thousands of cubic
meters of potable water
were registered in 2013.

IT IS VERY IMPORTANT
BECAUSE THANKS TO
POTABLE WATER WE
AVOID MANY DISEASES,
HOWEVER, IN SOME
COUNTRIES IT’S NOT
THAT EASY AND THAT’S
A PROBLEM WE NEED TO
RESOLVE.

Many companies
gain and use a lot
of money by
producing and
selling potable
water.

-It’s a very big process to produce potable water and a lot of money is invested to do it.
-We are very lucky for having potable water easily, but we must remember that not everybody is as lucky as we are.
