Water-related Fees

All persons who build, erect, alter, replace, operate, use or maintain wastewater treatment facilities in Missouri must pay the appropriate fees according to Missouri Revised Statute 644.057, RSMo, outlined in Code of State Regulations 10 CSR 20-6.011.

Paying Fees

Missouri Clean Water Fees fees can be paid by mail or electronically using JetPay. All customers who choose to pay electronically will be charged a convenience fee, according to section 37.007, RSMo. The convenience fee is retained by the third-party vendor, JetPay Inc., not the Missouri Department of Natural Resources. JetPay reserves the right to electronically debit a $25 service charge, if applicable, for processing an insufficient funds or closed account transaction from your designated bank account, in addition to any charges your bank may assess. Payment transactions are processed on JetPay’s secure and confidential website.

Fee Structure Changes

In 2025, the department organized a stakeholder workgroup to help review the fee structure to determine if any changes are needed. Meetings are held as needed and are open to everyone. For more information, visit Clean Water Fees Workgroup.

In 1992, Missouri's legislature enacted the Public Drinking Water Primacy Fee, Laboratory Certification Fee, Laboratory Services and Program Administration Fees and various operator certification fees. These fees establish a dedicated funding source to support the Missouri Department of Natural Resources' efforts to ensure adequate water for Missouri citizens that is safe to drink. The primacy fee provides funding necessary to implement the federal Safe Drinking Water Act and National Primary Drinking Water Regulations through the Missouri Safe Drinking Water Law and regulations. 

Missouri public water systems are subject to these fees according to Missouri Revised Statutes, section 640.100, RSMo, and outlined in Code of State Regulations, 10 CSR 60-16.

Paying Fees

The fees can be paid by mail or electronically using JetPay. All customers who choose to pay electronically will be charged a convenience fee, according to section 37.007, RSMo. The convenience fee is retained by the third-party vendor, JetPay Inc., not the Missouri Department of Natural Resources. JetPay reserves the right to electronically debit a $25 service charge, if applicable, for processing an insufficient funds or closed account transaction from your designated bank account, in addition to any charges your bank may assess. Payment transactions are processed on JetPay’s secure and confidential website.

Fee Structure Changes

Missouri Revised Statutes, section 640.100.8, RSMo, gives the department the authority to conduct a comprehensive review of the fees, with stakeholder input, and develop proposed changes to the fee structure, with stakeholder agreement. The goal of the stakeholder meetings is to review the fees and decide on a proposal to revise the fee structure through the rulemaking process. Once stakeholder agreement is received, the department must have the Missouri Safe Drinking Water Commission's approval before starting the rulemaking process. 

In 2020, the department held stakeholder meetings to discuss potential changes to the primacy, laboratory certification and laboratory services and program administration and operator certification fee structures. The fee structure change was needed to support the department's growing primacy responsibilities. With stakeholder agreement and approval from the Missouri Safe Drinking Water Commission, the amendments to the fee structure became effective Jan. 1, 2022.
