## Description

Statistically based method for estimating peak water supply demand.

The WDC results in more accurately sized systems consistent with the lower flow rates and consumption values from water-efficient plumbing fixtures and appliances. The WDC is designed to predict peak flow rates that would impose a demand load on any portion of the indoor water supply system including the building supply, main branches and risers, and fixture supply branches. Special Features include:

·         Preset list of Plumbing Fixtures
·         Drop down menus to add the number of fixtures
·         Can adjust flow rates lower than the preset values
·         Other fixtures not listed can be added
·         Three units of measure can be selected – GPM, LPM, and LPS
·         Calculates the peak water demand
·         Save feature allows sending results to an email, or download to your device
·         History page allows you to return to projects saved
