* The pipe diameter and slope of the distribution system
* The friction losses in the pipes
* The desired flow rate and pressure at the outlet point
By accounting for these factors and choosing the right collection strategies, you can create a system that delivers the optimal water pressure and flow rate for your needs.
Calculating Rain Barrel Size and Number
To determine the required size and number of rain barrels, calculate your roof’s catchment area, annual rainfall, and desired storage capacity. This will help you estimate the total annual rainfall that can be collected and decide how many rain barrels are needed to store that amount.
For example, a 1,000 square foot roof with an average annual rainfall of 40 inches can collect approximately 12,000 gallons of rainwater per year. If you want to store 50% of that amount for irrigation, you’ll need a system with a capacity of at least 6,000 gallons. Based on a typical storage efficiency of 75%, you’ll need 8,000 gallons of storage space to meet your goal.
For a given catchment area and desired storage capacity, use the following formula to calculate the required storage size:
Storage Size (gallons) = (Catchment Area x Average Annual Rainfall x Collection Efficiency) / Storage Efficiency
For example, using the values above:
Storage Size (gallons) = (1,000 sq. ft. x 40 in./year x 0.75 collection efficiency) / 0.75 storage efficiency ≈ 8,000 gallons
To achieve this storage capacity, you may need one or more rain barrels with a capacity of 1,000 to 2,000 gallons each, depending on the system design and other factors.
