  • Fleet Vehicles

    Forty Water Bureau dump trucks have been installed with engine coolant heaters to reduce idling.

The Water Bureau has a diverse fleet of over 400 vehicles including large dump trucks, service trucks, pickups, work vans, backhoes, excavators, passenger vehicles (including hybrids) and an all-electric Nissan Leaf. These vehicles are necessary to operate and maintain the water system. Bureau vehicles were driven over 1.6 million miles in FY 2012-2013 and used almost 236,000 gallons of fuel.

The bureau uses the following practices to achieve a more sustainable fleet: 

  • Tracks fuel use and mileage
  • Purchases the most efficient vehicles where feasible
  • Installs accessory equipment to reduce idling on trucks – engine coolant heaters warm the engine without the need to idle or waste fuel
  • Offers efficient pool vehicles to bureau staff
  • Provides training to employees to encourage fuel-efficient driving practices
  • Promotes the City of Portland’s Idle Reduction Policy
  • Uses Oregon biodiesel as part of the fleet fuel mix
  • Uses unleaded gasoline containing ten percent ethanol to comply with the Oregon Renewable Fuel Standard

The bureau has identified the following goals for average vehicle class efficiency (miles per gallon) of four vehicle classes by 2017:

Vehicle Class MPG Goal 2017
Heavy Duty Trucks 6 MPG
Light Duty Trucks 11 MPG
Sedans, Wagons & Minivans 26 MPG
