your household peak flow rate requirements

The design of effective and efficient home water treatment devices and filters requires reliable information on water use patterns in single-family home. Specifically, a full understanding of indoor peak water demands is essential.

The Water Quality Association (WQA) has undertaken an analysis of indoor peak demands in single-family housing in 2001. The WQA is the international trade association representing the household, commercial, industrial, and small community water treatment industry.

This report presents physical measurements of peak demand based on the most extensive dataset of single-family demands ever collected in North America – the Residential End Uses of Water study (REUWS). In this study, flow recorders were used to continuously monitor water use in 1,188 single-family homes in 14 cities. Each home was monitored for a period of four weeks – 2 weeks in the summer and 2 weeks in the winter. This is the largest and most extensive study of residential water use ever conducted.

The REUWS showed 99.96% of all events have peak flows equal to or less than 12 GPM (45 LPM). This means that only 0.04% of the measured peaks exceeded 12gpm (45 LPM). This indicates that the 12 GPM (45 LPM) sustained capacity of the home water treatment systems should easily be sufficient to meet the peak demands in 99.96% of all single-family water use events.

Based on the REUWS results, Homespring™ Central Water Filtration System has been designed to provide the peak flow rate ranged between 11 GPM (42 LPM) and 7 GPM (26.5 LPM) to meet your specific household water peak demand sufficiently for all water use events.

WQA maintains a close dialogue with other organizations representing different aspects of the water industry in order to best serve consumers, government officials, and industry members. WQA is a resource of information, of product testing, and professional certification for all water users.
