What is the required raw water pump capacity in gpm per connection for surface water suppliers?

The required raw water pump capacity for surface water suppliers is set at 0.6 gallons per minute (gpm) per connection. This standard is based on the average water demand anticipated for a household connection and is designed to ensure an adequate supply of water for both daily use and peak demands. The figure of 0.6 gpm allows for a sufficient flow rate to meet typical residential needs, taking into account factors like fluctuations in water usage throughout the day and the necessity for reliable service during peak times.

This capacity ensures that surface water suppliers can maintain a consistent and reliable water supply for their customers, aligning with regulatory requirements and industry best practices for water provision. Understanding this standard is crucial for those working in water supply management and infrastructure planning, as it directly impacts the design and sizing of the pumping systems used to deliver water from surface sources to consumers.
