A4.3 The Level of Service Standard and Typical ERC Assumptions

A4.3, the Level of Service Standard and Typical ERC worksheet, is one of the most important programs in WATER Power Tools™. The statistical supply and demand information you input into A4.3 paints the picture of an average water user or ERC (Equivalent Residential Connection) for your system and further determines the expected level of service for a typical system customer.

The ERC standards developed in A4.3 carry over into the other worksheets that are part of the WPT™ Water Mechanics program to establish a cohesive and uniform analysis of your system.
