AWWA Tools

AWWA has created a toolbox of online interactive tools developed as guidance and support tools for water professionals. On this page, you will find tools to optimize operational performance, inform management decisions, or standardize a task.

Water Audit Software v6.0

This spreadsheet-based water audit tool is designed to help quantify and track water losses associated with water distribution systems and identify areas for improved efficiency and cost recovery. It provides a "top-down" summary water audit format, and is not meant to take the place of a full-scale, comprehensive water audit format.

Effective Useful Life Tool

The Water Utility Facility Asset EUL is spreadsheet-based tool to assist in determining the effective useful life (EUL) for facility-based treatment, storage, and pumping facility assets for water utilities. Understanding the effective useful life of an asset is a key component of an asset management program as it supports an initial determination of the estimated renewal needs. 

Cybersecurity Tool

The AWWA Cybersecurity Tool represents a voluntary, sector-specific approach for adopting the NIST Cybersecurity Framework as expressed by the Water Sector Coordinating Council. The Cybersecurity Tool generates a prioritized list of recommended controls based on specific characteristics of the utility.

Hypochlorite Assessment Model

To support our utility members, AWWA has developed a web-based predictive modeling tool (Copyright 2011 AWWA) intended to provide member users with approximate guidance on the degradation of hypochlorite and levels of selected degradation byproducts at their sites.


CyanoTox 3.0

This updated tool builds on the success of its predecessor in helping utilities calculate their system’s oxidation options for cyanotoxins, while adding new features including:

  • pH range has been expanded to 6-10
  • 95%-confidence intervals added for reactions where natural microcystin mixtures may have different rates
  • Microcystin kinetics (based on MC-LR) now have suggested relative rates for some other variants
  • Increased validation of the model’s kinetics, to be published in peer-reviewed articles.

Flange Torque Calculator

This online interactive tool can be used in conjunction with AWWA’s Manual M11 to determine the recommended torque ranges and other important flange details, gasket stresses, and bolt yield loads.


Benchmarking is a form of continuous improvement designed to help utilities to improve their overall operational efficiency and effectiveness. 

Through the AWWA Utility Benchmarking Program, utilities can use established performance indicators to track their own performance and  identify areas that could be improved.

The AWWA Utility Benchmarking Program provides these objective performance measures  to track  organizational performance through an on-line survey and data portal.

Utility Emissions Reduction Tool

With predictive day-ahead electricity grid emission data that will be provided by E2i, water utility operators can quickly, easily, and consistently reduce the carbon and mercury emission impacts of pumping, filter washing, aeration and other flexible energy-intensive operations.
