AWWA Water Balance (Source: AWWA M36 Manual, 4 th Ed., 2016) 17 AWWA Water Balance Terms and Definitions Water Balance Term Volume From Own Sources Water Imported System Input Water Supplied Water Exported Authorized Consumption Water Losses Apparent Losses Real Losses Revenue Water Non-Revenue Water Definition This is the volume of water withdrawn (abstracted) from water resources (rivers, lakes, streams, wells, etc.) controlled by the water utility, and then treated for potable water distribution. The Water Imported volume is the bulk water purchased to become part of the Water Supplied volume. Typically, this is water purchased from a neighboring water utility or regional water authority. The System Input volume is the annual volume input to the water supply system. This equals the Volume From Own Sources plus the Water Imported volume. The Water Supplied volume is the annual volume of treated water delivered to the retail water distribution system. This equals System Input volume minus the Water Exported volume. The Water Exported volume is the bulk water conveyed and sold by the water utility to neighboring water systems that exists outside of their service area. Authorized Consumption is the annual volume of metered and/or unmetered water taken by registered customers, the water supplier, and others who are authorized to do so. This is the difference between System Input volume and Authorized Consumption, consisting of Apparent Losses plus Real Losses. Apparent Losses involve systematic data handling error (in the customer billing process), all types of customer metering inaccuracies, and unauthorized consumption. Real Losses are the annual volumes lost through all types of leaks, breaks, and overflows on mains, distribution reservoirs, and service connections up to the point of customer metering. Revenue Water pertains to those components of System Input Volume that are billed and have the potential to produce revenue. This is the sum of Unbilled Authorized Consumption, Apparent Losses, and Real Losses. This value can also be derived by calculating the difference between System Input Volume and Billed Authorized Consumption.

Federal guidance for evaluating alternatives for water supply projects now includes Best Practices for Conservation and Water Efficiency (including water loss control) A number of state, provincial, and regional water regulatory agencies now require water utilities to regularly submit water audit data in a standardized format that allows for reliable tracking and benchmarking of utility performance. Bond rating agencies are also evaluating water loss performance to establish a water utility s Enterprise Risk Factor Rating. 24 Please consider the environment before printing. 12

Annual Reporting with Standard Terminology - Reports of water loss using industrywide definitions are required each year. AWWA Free Water Audit Software - Utilities are to report water losses in an electronic format developed and endorsed by the water utility industry. Validation of Data - Third party experts or trained evaluators review the information and data sources used by utilities to prepare water loss audit reports ( Level 1 validation). Volume-Based Performance Benchmarks - Goals or targets are being set to reduce water losses by specific volumes. 32 Please consider the environment before printing. 16

17 Georgia Georgia has been a national leader in water loss management policy. It was the first state to go beyond the annual requirement for utilities to use AWWA water loss software by instituting a program for validation of the submitted audits per AWWA best-practices. Georgia has also adopted a performance standard regulation that requires each water supplier to develop and conduct a water loss control program and demonstrate demonstrable progress toward improvement, based on non-percentage performance measurements.

Beginning 2017, all audit reports must be validated, and will be posted on the web.

22 Resources Model State Legislation Version B Provides guidance and an initial period of time to educate policymakers and water utilities prior to implementing mandatory requirements based on Version A Key Takeaways Water auditing and water loss reporting requirements of State and other regulatory agencies in the US vary widely. A broad spectrum of parties are increasingly concerned about water inefficiency, Their perspectives should be considered when formulating regulatory oversight and water utility implementation of effective water loss control programs. Water loss performance is best defined, and informed decisions when planning and implementing water loss control programs are best made, when the underlying data used in water audits are validated by qualified personnel using standard protocols embodied in the AWWA M36 Methodology and Free Water Audit Software. The above-noted interests of water purveyors and other stakeholders are best served when they actively collaborate with regulatory agencies in the development of effective regulatory programs. 44 Please consider the environment before printing. 22
