Uunder new state rules being adopted later this year by the Whatcom County Health Department Septic systems will be required to get regular inspected .
Conventional tank-and-drainfield systems will need to be checked every three years, while more complex, modern systems such as a pressure mound or Glendon biofilter must be inspected annually, by a licensed inspector.
The system will also be required to be inspected on the sale of property.
I have never heard of a septic system that pumps to a sewer, I suggest you ccntact your local city officials in Lynden and at Whatcon County.
Let us know what you find out.
I’m looking for information on a septic system that pumps to the sewer in Lynden. Does it require a permit – there is none on file at the Whatcom Health Department? What kind of maintenance is needed? Anything else you can share will be appreciated.
