  • We have a design capacity of 8.0 MGD with a maximum capacity of 12 MGD.
  • Our aeration system is used to release entrained gases, oxidize soluble minerals, and raise the raw water pH.
  • We then use flash mixing with chemicals to oxidize soluble manganese and begin the formation of solids.
  • Flocculation is done to complete the formation of solids.
  • Clarification is required to provide a zone to filter and settle the solids.
  • Filtration traps any solids that did not settle, and polishes the water for clarity.
  • Post chemical addition of chlorine is used to disinfect. Fluoride is used to help prevent tooth decay and polyphosphate, and minimizes mineral deposits in the distribution system.
  • Clearwell detention ensures chlorine has completed the disinfection process.
  • Finally, pumping provides the pressure necessary to distribute the water throughout the distribution system.


  • Booster pumping stations provide additional pressure to areas that cannot be served by tank elevation pressure.
  • Storage tanks and reservoirs provide volumes of reserves to compensate for high consumption periods when plant production cannot meet the need and for firefighting reserves in emergencies.
  • Our storage capacity is 11.4 MGD.
  • PUB currently maintains 1,174 hydrants located throughout the distribution system for flushing of the system and for use by the fire department when necessary.
