What is the minimum capacity required per connection if ground storage is the only storage available?

The minimum capacity required for ground storage when it is the only source of storage is established based on guidelines that consider peak demands and the need to ensure reliability in water supply. The standard specification for water supply systems typically suggests a capacity of 200 gallons per connection. This figure is crucial as it helps ensure that adequate water is available for individual users while also catering to fluctuations in demand, such as during peak usage times.

This capacity takes into account factors such as emergency supply needs, fire protection, and regular domestic consumption. A lower capacity, such as 150 gallons, may not sufficiently cover these needs, which could lead to shortages in critical situations. Conversely, higher capacities, like 250 or 300 gallons, while more ample, are typically not mandated for minimum requirements unless specific conditions or regulations dictate otherwise.

By establishing the minimum capacity at 200 gallons per connection, water systems can maintain a balance between having enough water available for all users and the logistical considerations of storage and supply management. This ensures a reliable and resilient water system that can perform optimally under varying demands.
