"The mission of Three Lakes Water & Sanitation District is to provide efficient, reliable, non-disruptive and environmentally sound wastewater treatment service to the community of Grand Lake and the surrounding areas.  Our goal is to protect the public's health, safety, and environment by minimizing adverse effects from the treatment, disposal and transportation of solid waste at minimal cost to our constituents."

MAY 6TH ELECTION RECOUNT
A recount will occur on Thursday, May 15, 2025 at 4:00 p.m. at the District Offices located at 1111 County Road 48, Grand Lake, CO 80447. Should a tie still be present following the recount a lot drawing by the Canvass Board, which consists of a board member and eligible elector, will occur prior to election certification. 

NEW BILLING SYSTEM
We have transitioned to a new and improved billing system, Muni-Link.

Every ratepayer has been assigned a new account number, and will be required for all payments. You can find this number on your bill or the registration email sent out to your email address on file with us prior to the conversion. Depending on your preferred method of payment, there might be some action required.

If you currently pay by:

• ACH – No action is required. We will process your next payment on April 25th as usual.
• Bill Pay through your bank – Bank checks that were previously mailed will now be electronically processed. All you need to do is update your payment information by referencing your new account number.
• Check – Please reference the new account number on your payment. 
• Portal - to sign up for the portal you will need to have your new account number and customer ID (CID) number, found on your bill or registration email.
