    Vegetated Swale Specifications

    Swales with a gentle slope (less than 4% average) are the most effective at treating stormwater.  The maximum slope must be less than 6%.  Facility storage depth may range from 2 to 12 inches.  A freeboard (6 to 12 inches) may be required if the adjacent area would be damaged by flooding.  Maximum side slopes are 3 horizontal to 1 vertical; slopes and depths should be minimized to the extent practical for aesthetic and safety reasons.

    Wastewater Rate FAQs

    At the City of Sandy, we understand that many members of our community have been feeling the impact of the recent increases in wastewater (sewer) rates.  We put together this FAQ page to answer some of the most common questions people have raised.  If you have additional questions, please feel free to contact the City at 503-668-5533 or utilit

    How can I share my feedback with the City Council?

    The Sandy City Council always welcomes comments and feedback from residents.  City Council meetings are open to the public, and each meeting includes a public comment period where anyone can address the Council (typically for 3 minutes each).  Meeting information is available at https://sandy.civicweb.net/portal/.  If you have a letter or email you would like to be considered by the Council at one of its meetings, send it to

    What about all the new houses - will developers pay their fair share?

    In addition to the monthly fee increases, new commercial and residential development projects will pay their fair share for the required sewer investments. System Development Charges, which are paid by new development, were increased from $1,834 to $4,889 for each new home in 2020, and are proposed to increase to $5,157 in 2021.  View the Wastewater System Improvements page.

    How can I be sure utility revenue will be spent appropriately by the City?

    It is important to know that per state law, wastewater rate revenue must only be used on the city’s wastewater utility. The revenue raised by the wastewater rate increase will be used to pay for the principal and interest on loans and special financing for the wastewater system improvements. The city is financially audited on an annual basis to ensure laws are followed and dollars are spent legally and appropriately.  View the publicly available audit results. 

    Where can I learn more about the wastewater system improvements?

    There is a great deal of information on the reasons wastewater rates had to be increased, how Sandy’s rates compare to other area cities, and the required improvement projects currently underway available on the project overview page.

    Is there any assistance available if I can't pay my bill?

    The City Council approved an assistance program to help lower-income individuals afford their utility bills.  Those who meet the income threshold can have the wastewater portion of their bills reduced by 50%.  For more information, visit the customer assistance program page
