The Potable water treatment plant of Chamisero, with a cost of execution of 21 milion €, is projected to supply of potable water (1000 L/s) to the zones of Chicureo and Chamisero (zones with cover of Manquehue waters in the commune of Hill).

The treatment plant has the following processes:

• Capture work in Canal Batuco.
• Preliminary stage:
  • Screening (coarse and fine).
  • Addition of lime and sodium hypochlorite (prechlorination).
  • Raw Water (PEAC) and desanding plant.
• Primary stage:
  • Gutter Parshall (Measurement of flow and addition of coagulant, Polymer anionic, cationic or non-ionic and activated carbon)
  • Rapid mixing chamber and addition of chloride or ferric sulfate.
  • Distribution Chamber.
  • Predecantación.
• Secondary stage:
  • Parshall Gutter (addition of chloride or ferric sulphate), potassium permanganate and sodium hypochlorite for oxidation.
  • Rapid mixing chamber and addition of polymers.
  • High-rate decantation.
• Filtration.
• Disinfection (Bactericidal hypochlorite) and addition of fluorine.
• Dosage rooms and chemical warehouses.
• Administration building, control room and water quality sampling.
• Extraction, dehydration and sludge disposal system:
  • Sludge equalization Pond and equalized sludge-lifting plant.
  • Delivery camera.
  • Thickeners of sludge and hoisting plant of thickened sludge.
  • Pond of sludge accumulation and lift plant to centrifuges.
  • Dehydration and sludge disposal building.
