Septic Maintenance Rebate Program

Evaluating and Maintaining Septic Systems Costs Money...We Can Help!

Having your system regularly inspected and performing maintenance tasks saves you money in the long run and helps protect our waters, but we understand that it takes time and money right now.  The septic rebate program can reimburse you for costs associated with a system evaluation, installation of operation and maintenance equipment, or septic tank pumping.

Clean water is essential for human health and for the health of fish, shellfish, wildlife, and livestock. Everyone, including you, is in a watershed right now. A watershed is an area of land where all of the water drains to a common point, such as the mouth of the Nooksack River. Activities in our watershed affect the water quality of streams, rivers, and bays.    

Maintaining your septic system is part of the solution to improving water quality in your neighborhood and for the community downstream.


Septic Rebate Program Under COVID-19 Restrictions

Whatcom County Health Department in-person septic system workshops have been postponed until further notice.  These workshops are required to become eligible for the septic rebate program.  On a temporary basis, we are able to offer these options:  

If you have completed an in-person workshop within the last 3 years (in 2019) 
If you have completed an in-person workshop, but it has been over 3 years
If you have not completed an in-person workshop
Submit your rebate application with a copy of your invoice for work done on your septic system.

Make sure to put the date of the workshop you attended on your rebate application
Complete the refresher quiz and include it with your rebate application and a copy of your invoice for work done on your septic system. Complete the Health Department’s online training and submit your application with the attached quiz and invoice now.
Wait until the in-person workshops resume and submit your application after you have completed the training. 

 Rebate applications can be received for 12 months after the work on your septic system has been completed. Grant funds will still be available for rebates after in-person workshops resume.


Please email with any questions about these changes. Scroll down for further information and instructions for receiving a rebate.

What Rebates Are Available?

Rebates are available, based upon actual costs, for system evaluations, installation of equipment, or septic tank pumping. You will need to choose one rebate activity per property.

System Evaluation by a Licensed Professional (up to $100)

Evaluations are required every 1-3 years depending on the type of system you have. Replacing a failing septic system can be very expensive. Inspections are important because they can reveal minor problems in the system before they turn into major, expensive problems later.

Septic Tank Pumping by a Licensed Professional (up to $200)

Pumping is a type of maintenance that may be identified in your inspection. The inspector will measure the solids in your septic tank. Your septic tank needs to be pumped when the solids in the tank make up about 1/3 of the total tank volume.

Equipment Installation (up to $100)

Equipment such as risers and lids, baffles, or outlet filters can help with the effectiveness and ease of operation and maintenance activities for your septic system.
