Clean Water Infrastructure Loans

Financing for water and wastewater utilities upgrading infrastructure to reduce energy use and greenhouse gas emissions.

CEFTX prioritizes investment in certain communities; however, all financing remains subject to underwriting, eligibility requirements, and program availability.

Water and wastewater treatment accounts for roughly 3% of total U.S. energy consumption. For individual utilities, electricity costs can represent 25-30% of annual operations and maintenance budgets.

CEFTX provides construction and permanent financing for clean water infrastructure upgrades that reduce those costs and cut greenhouse gas emissions.

The Energy Cost Challenge for Water Utilities

Water utilities face a structural energy cost problem. Moving and treating water requires electricity at every stage, from pumping source water, to filtration and treatment, to pressurizing distribution systems and managing wastewater discharge. These costs are largely fixed and tend to increase over time.

Per the EPA, water and wastewater treatment represents approximately 3% of total U.S. energy consumption. Utilities typically spend 25-30% of annual operations and maintenance budgets on electricity. For small and rural systems operating on tight margins, this is often the single largest controllable expense.

Infrastructure upgrades that improve energy efficiency or add on-site generation can meaningfully reduce these costs and reduce the greenhouse gas emissions associated with utility operations. CEFTX’s clean water infrastructure loan is designed to make those upgrades financially accessible.

Part of the Texas Clean Water Access Initiative

This loan product sits within CEFTX’s broader Water Initiatives program and the Texas Clean Water Access Initiative; a collaborative effort to modernize water infrastructure across the state. CEFTX is working with utilities, nonprofit partners, and regional organizations to build a portfolio of projects focused on:

  • Small utility modernization
  • Renewable-powered water and wastewater facilities
  • Rural and tribal clean water access
  • Water loss reduction and system resilience

In 2025, CEFTX and the South Texas Water Authority were awarded a $250,000 grant to launch a clean energy investment pipeline for water infrastructure in South Texas; one example of the collaborative, equity-focused work that drives this initiative.
