Water Loss Control Program
Program Overview

Thank you to everyone who has applied for the program. We are now at full capacity and have started a waiting list. You can sign up for the waiting list by submitting an application. We will contact you if and when a space becomes available.

WIFA, in partnership with the Arizona Department of Water Resources (ADWR), is kicking off Phase 2 of its Water Loss Control Program. The program utilizes the American Water Works Association’s (AWWA) Program for Water Audits and Loss Control Programs, which explains the industry’s best practice for water loss accounting, otherwise known as the M36 methodology. The purpose of the Water Loss Control Program is to provide utilities with a foundational understanding of the M36 methodology, how to apply the methodology, and how water audit data may be used to asses and improve water loss performance at the utility level.

The M36 methodology is cost-effective because it analyzes costs of loss components, and includes a validation mechanism. Research has shown that without validation, systematic error can cause many water audits to be unreliable which can lead to unintentional, erroneous system management. The M36 methodology expresses metrics in terms of validity, volume and value for each water loss sub-component. Validity is the most important of these metrics, as it indicates the reliability of the other metrics in the water auditing process. The program will include a unique validation process where water loss experts review supporting documentation and interview utility staff to substantiate the contents of each water audit.

A contractor to be selected will help in M36 methodology training and metrics validation process, modeled after the pilot project.

In this program, utilities will be trained on the M36 Methodology, the AWWA Water Audit, and in developing the next steps in their own system water loss mitigation control program. The program will consist of the following:
  • A kick-off webinar for all participating utilities
  • An in-person, two-day workshop for the participants hosted in their region
  • Training in the AWWA Free Water Audit Software
  • Data analysis and consultation with a contractor to be selected
  • Final system profile deliverables and water loss control recommendations
Approximately 25 small to medium-sized systems across Arizona will be selected to participate in Phase 2. See below for selection criteria.

Eligible Systems

All systems that meet the following criteria are invited to apply.
  • Must be a Community Water System as categorized by the Arizona Department of Environmental Quality (ADEQ)
  • Must be eligible for WIFA funding (see for more details:
  • Must serve a population between 3,000 to 50,000 people
  • Must be a metered system (both production meter(s) and customer meters)
  • Must have the appropriate technological capacity to participate in the webinars and software programs

Webinars and Trainings

Participating in this program requires a commitment to attend the various trainings and complete the program in full. The kick-off webinar meeting requires mandatory attendance and will be announced at the beginning of the program. The subsequent in-person trainings will require at least one person in attendance, but several representatives from each system is highly encouraged. Scheduling of the in-person trainings will be announced early in the program and will take place in a centralized location based on program participants. Additionally, each system must have the appropriate technological capacity to participate in the webinar and software program training sessions.
