Users of the system are charged a flat rate sewer use fee to pay for costs of constructing, operating and maintaining District sewerage facilities, as well as costs for wastewater treatment and disposal.

Likewise, a monthly fee is charged to all undeveloped, buildable lots located within the Cayucos Sanitary District boundaries to pay for the expense of maintaining a sewer system available to vacant properties.

As a property owner in the Cayucos Sanitary District, you are responsible to pay sewer fees as follows:

Monthly Billing Fees: 

Sewer Use Fee 

       Single Family Residences - $98.00 per month

        Multi-Family Residences - $98.00 per month, per EDU (Equivalent Dwelling Unit)

Vacant Lot Fee

       Undeveloped, Buildable Lots - $7.50 per month


If you have purchased property within the Cayucos Sanitary District boundaries, it is your responsibility to contact our office and provide your contact information.

In the event you fail to make contact, an account is still tied to your property and billed on a monthly basis. All bills that are not paid on or before their due date are assessed a 10% late fee, without exception. Payment must be received by District staff no later than the last day of each month in order to be considered on time. Annually, the District reports its delinquent accounts to the SLO County Assessor's Office for inclusion on the County tax roll. 


Would you like your tenant to be billed in lieu of you? 

At your request, the District will create a "Tenant Account" to allow your tenant to receive the monthly bill and make payments on your behalf.  Please call our office at (805) 995-3290 to authorize this change. You will always be required to sign a form to authorize any change to your account. Please note: In the event your tenant does not make timely payments and accrues a balance, their balance will automatically be transferred to your owner account when they move out. As the property owner, it is ultimately your responsibility to pays all sewer fees assessed to your property. 


Sewer Connection Fee:

Each undeveloped, buildable lot in Cayucos that wishes to connect to the sewer system for the first time is required to pay a one-time Connection/Inspection Fee - $7,960.00
