Friday, September 16th, 2011, Itxel and I headed to visit two other districts in the Huaura province, Sáyan and Végueta. They both receive water treatment services from EMAPA Huacho. Sayán is roughly a 45-minute drive inland and into the mountains, while Végueta is right on the coast, about 20 minutes north of Huacho. We spent the day visiting the two sites with an engineer from EMAPA Huacho, Juan Candia. He wanted to show us the potential locations for new waste water treatment plants in both of these locations.
From everything that I have learned so far in Huacho, this is how their water system works:
1) Pump water from the ground.
2) Inject water with chlorine gas to help clean it.
3) Pump water up to a water tower on a hill/elevated area, to insure water pressure throughout the town.
4) Water drains down into subscriber's homes/businesses using the flow of gravity (only Sayán has continuous service 24 hours/day).
5) Waste water drains by means of gravity to a central location.
6) Untreated waste water gets dumped into river (in the case of Sayán) or ocean (in the case of Végueta and Huacho).
