1. Plant Intake – Water is diverted from the Weber River to the water treatment plant.

2. Coagulation – Chemical coagulants are injected into the rapidly flowing water as it enters the plant. This begins the immediate attraction and clotting of the suspended particles in the water.

3. Flocculation – Water then goes through a mixing process by passing through a series of baffles and mixing paddles, which slowly rotate in opposite directions to each other, each paddle rotating slower than the previous to prevent the clumped particles from breaking apart. This continues the clotting process, called flocculation, and produces larger particles.

4. Sedimentation – The water continues moving through a long narrow deep basin at a very slow rate to allow the particles to sink to the bottom of the basin. The sediment at the bottom of the basins is then collected and conveyed to the residual dewatering facility.

5. Ozonation – The water is sent from the sedimentation basins to the ozone contact basins where it moves through a series of baffles after ozone is added to the water. The ozone is a very strong oxidant which consumes mostly organic particles in the water, eliminating bad taste and odor compounds. Ozone is generated by combining oxygen and electricity. Excess ozone is neutralized before continuing to the filters.

6. Filtration – Water in then directed through the filters, which are deep basins containing 5 feet of anthracite coal and torpedo sand media. This filter traps the remaining particles in the water. The water exits the filters through finely slotted cones in the bottom of the filter.

7. UV Disinfection – The water then passed through one of four Ultra-violet light chambers, which sterilize and debilitate any remaining organisms such as Giardia and Cryptosporidium. Each chamber contains 72 UV lamps.

8. Chlorination – Chlorine is then added to the water just before it leaves the plant, as a disinfectant, to safeguard against contaminants as the water travels through the many miles of distribution piping to the homes and businesses.

9. Residual Dewatering – Heavy particles are collected during the sedimentation and filtration processes and conveyed to the settling ponds and to the gravity thickeners, where they are held for an extended period of time to allow further concentration of the solids. After enough solids are accumulated in the thickeners, it is sent to the centrifuge facility where most of the water is separated from the solids. The water is sent to the head of the plant again and the solids are loaded in a truck and hauled to a landfill.
