How We Get Our Water To You

Water Capacity

  • The District maintains 798 miles of pipe, ranging from 2 to 60 inches.
  • 12 pumping stations are online to transmit water from the gravity flow water main to higher elevations within the District.
  • The gravity flow main is a 60-inch water main serving the District from Portland's Powell Butte Reservoir.
  • The District's gravity line capacity is 42.3 MGD, with another 10 MGD available from the Joint Water Commission, an amount well above the average and peak daily flow.
  • There is an emergency standby pumping capacity of 20 million gallons a day (MGD) that can be used to back up the gravity flow main.

Water Storage

Within the system, there are 23 covered reservoirs with a combined storage capacity of 67.35 million gallons. Some reservoirs are below ground with Park and Recreation District tennis courts, ball and soccer fields built on top. The major pumping stations and the reservoirs have full telemetry control systems.

Security

The District's water system is monitored 24 hours a day, seven days a week. In addition to watching water flows and pressure, our state-of-the-art Supervisory Control and Data Acquisition (SCADA) system monitors several water quality parameters and security alarms. If the system identifies anything out of the ordinary, alarms alert an operator to the possible problem and staff are dispatched as needed.
