Sanitary Sewer: 

Fixed Charge: Each customer is charged based on the number of equivalent dwelling units (EDUs). Single-family residential units are usually counted as one EDU, while a duplex would be counted as two EDUs, and so forth. This charge is used to pay the fixed costs of running the wastewater systems, and includes construction of pipes required to collect sewage and operation of the Clean Water Services wastewater treatment facilities.

Clean Water Services is the regional provider of wastewater, and the City partners with Clean Water Services to provide those services within Hillsboro. The City retains about 16.4 percent of the fixed charge, and the remainder (roughly 83 percent) is submitted to Clean Water Services on a monthly basis. Please visit Clean Water Services for further information on the sanitary sewer services, or call 503-681-3600.

Use Charge: Your sewer consumption is based on your average water consumption between the months of November and April. The November through April time period is referred to as the wintertime average and is used because customers typically consume less water during this time when they are not irrigating. Each customer's wintertime average is calculated and adjusted each July to determine the average use charge for the upcoming fiscal year (July through June). The wintertime average is a good indicator of the wastewater your household produces and discharges into the sewer system.

The City retains about 16.6 percent of the average use charge, and the remainder (roughly 83 percent) is submitted to Clean Water Services on a monthly basis.

Example: A customer's water usage, from the bi-monthly bills is as follows:

November through December: 18 hundred cubic feet used
January through February 16: hundred cubic feet used
March through April 20: hundred cubic feet used

18 + 16 + 20 = 54 / 3 (billings) = an average of 18 hundred cubic feet (ccf) or 9 ccf per month.

The customer's wintertime average during the November through April period would be 18 hundred cubic feet (ccf) for a bi-monthly bill or 9 for a monthly billing.

Local Service Fee: This fee funds the repair and replacement of sanitary sewer infrastructure systems. The City retains 100 percent of this fee, which is used to invest in specific system improvement projects. 

Surface Water Management 

Fixed Charge: Each customer is charged based on the number of Equivalent Service Units (ESU), which is a measurement of the impervious (non-porous or waterproof) surface areas on a property. Single-family residents are considered to have one ESU (2,640 square feet of impervious surface area). All non-single family residential properties are calculated based on the actual amount of impervious surface area. The fee pays for drainage and water quality programs, including storm drain cleaning, erosion control, pollution control, and emergency flooding response. The fee is needed to meet environmental regulations and satisfy local storm drainage needs.

Clean Water Services is the regional provider of surface water management, and the City partners with Clean Water Services to provide those services within Hillsboro. The City retains about 75 percent of the fixed charge, while the remainder is submitted to Clean Water Services on a monthly basis. Please visit Clean Water Services for further information on surface water management services, or call 503-681-3600.

Local Service Fee: This fee funds the repair and replacement of surface water management infrastructure systems. The City retains 100 percent of this fee, which is used to invest in specific system improvement projects.

Transportation Utility Fee (TUF): 

The Transportation Utility Fee (TUF) pays for needed street maintenance and repairs to help keep City streets well maintained. It also provides limited funding for pedestrian and bicycle infrastructure improvements projects.

The TUF is based on the estimated number of roadway trips generated by a property. For residential customers, the amount of trips is the same for each dwelling unit and the fee is a flat rate per dwelling unit. For non-residential customers, the use of the property determines the trip generation rate which, in turn, determines which of the seven non-residential billing rates the property receives. For most properties, the fee is determined by multiplying the square footage of the structures by the appropriate billing rate.

Water:

These charges fund the costs involved with treating and delivering drinking water. Costs include the construction, operation, and maintenance of the City of Hillsboro’s water system. Water rates are set by the City of Hillsboro Utilities Commission.

Fixed Charge: All customers pay the fixed charge. The charge invests in Hillsboro’s water system and infrastructure, and ensures delivery of water to customers for their use. The fixed charge does not include the amount of water used by the customer.

Use Charge: This charge is based on the amount of water used during the billing period and is measured by the customer’s water meter. Water use is measured in increments of 100 Cubic Feet (CCF). One (1) CCF = 748 gallons.

Customer Account Set-up Fee:

Customers within the City limits are charged a $15.00 account set-up fee for setting up a new account. Customers outside the City limits are charged a $35.00 account set-up fee.
