A utility revenue bond finances public utility infrastructure and is repaid primarily from utility system revenues rather than broad taxing power.
A utility revenue bond is a municipal revenue bond repaid primarily from revenues of a public utility system, such as water, sewer, electric, gas, stormwater, or solid-waste operations. The bond is usually supported by user fees and system charges rather than by the issuer’s broad taxing power.
A city or utility authority issues bonds to build, repair, or expand a utility system. Customers pay rates or charges for the service. After operating expenses and required transfers, pledged system revenues are used to pay principal and interest.
The exact pledge matters. Some bonds are senior lien obligations on net system revenues. Others may be subordinate, limited to a project, or supported by additional reserves. The official statement and bond indenture define the security, not the phrase “utility revenue bond” alone.
| Feature | Utility Revenue Bond | General Obligation Bond |
|---|---|---|
| Main repayment source | Utility system revenues, usually user charges. | Broad taxing power or full-faith-and-credit pledge, subject to legal limits. |
| Main operating risk | Demand, rate affordability, regulation, capital costs, and operating expenses. | Tax-base health, budget balance, debt burden, and legal authority. |
| Key documents | Official statement, rate covenant, engineering reports, audited financials, and continuing disclosures. | Official statement, budgets, audits, debt schedules, tax-base data, and continuing disclosures. |
| Typical examples | Water, sewer, electric, gas, or stormwater systems. | City, county, school district, or state public-purpose debt. |
A water authority issues bonds to upgrade treatment facilities. The bonds are expected to be paid from water and sewer charges. If the authority can adjust rates and has stable demand, the pledge may be stronger. If rates are politically constrained, operating costs spike, or a large customer leaves, coverage can weaken.
| Evidence | Why it matters |
|---|---|
| Rate-setting power | Determines whether the utility can raise rates to maintain coverage. |
| Debt-service coverage | Shows cushion between pledged revenues and required debt service. |
| Customer base | Large-customer concentration or population decline can change demand risk. |
| Capital plan | Utilities often need ongoing infrastructure investment and future borrowing. |
| Regulation and affordability | Rate approvals, environmental rules, and affordability constraints can affect cash flow. |
| Lien and flow of funds | Senior, subordinate, and reserve-fund provisions determine payment priority. |
| Call features | Refinancing or call provisions can change realized investor return. |
