Are there any rules for sizing receiver basins?
In some areas, local codes may dictate the size of the receiver basin. If not, the most important guideline is to make sure the basin is big enough to do the job. Select a receiver basin with a total volume of 2 to 3 times the pump capacity. If possible, specify a tall basin rather than a wide basin. If the basin is too wide, solids may settle out on the bottom and cause service problems.
