On-site wastewater treatment system installer License Application/Renewal
How to Apply or Renew your License
- Apply or renew online through the Citizenserve Citizen Access Portal. The portal will allow you to quickly enter all necessary information as well as upload your required documents.
Paying for Your New or Renewed License
Payments may be made through the Citizenserve Citizen Access Portal using a credit card. If paying by check, please make check payable to St. Charles County Building and either mail to or deliver in person at 201 N. Second St, Ste 410, St. Charles, MO 63301.
Please note: Your license is not active until payment is received and all required documents have been verified.
Current Submittal Requirements
- License application through the Citizenserve Citizen Access Portal.
- Proof from Missouri Department of Health and Senior Services of valid certification as an On-Site Wastewater Treatment System Installer. Contact them at (573) 751-6400 for more information.
- One digital front facial view photograph.
- Current bond in the amount of $10,000 with licensee name as Principal (NOT the company name.) An original is required, it must be signed, and the power of attorney page must also be included.
- Current Certificate of Liability insurance in the minimum amount of $500,000 per occurrence.
The certificate must show St. Charles County as certificate holder.
- On-site Wastewater Installer licenses are valid for 2 years, until December 31, in years ending in odd numbers. As such, if you are first applying for your license at any time in an even numbered year, the full fee of $200 for an active license will apply. Conversely, if you apply at any time in an odd numbered year, the fee for an active license is $100.
- $25 one-time processing fee due for first time applicants.
Once the application has been received, all required documents verified, and all required fees posted, the license will be activated and the licensee will be sent a receipt and a license certificate via email.
Another license option is to go "Inactive" for a fee of $50. This option is only available to previously licensed individuals. An "inactive" license status works for those who do not expect to work in the area but it is still a possibility. This status keeps the license "current" while not requiring bonds or liability insurance. If the licensee should get a job in the County, all that is required is the current license fee ($200 or $100, depending on what year in the cycle it is), along with current bond and liability.
Towards the end of a license cycle, around November 15, renewal reminder notices will be emailed. This is a courtesy, as it is the licensee’s responsibility to keep their license up-to-date and in good standing. As such, license applications and payments MUST be postmarked on or before December 31 or a late fee of $25 will be applied. For each month thereafter, up to 4 months total, a late fee of $25 a month will be charged. For example, this means that if you do not renew your license until the July after it was due, the fee for that license would be $200 plus $100 in late fees.
Additionally, if a license remains expired for two (2) or more code cycles (codes cycles last three years), licensee will be required to re-test with the International Code Council.
