The NCSPA Pipe Storage Capacity Calculator helps engineers, designers, contractors, and stormwater professionals estimate storage volume for corrugated steel pipe systems. Select a pipe size and corrugation profile, then enter the total pipe length to calculate storage capacity in cubic feet and gallons.
Use this lookup tool for preliminary stormwater storage, detention, and underground pipe storage planning. Values are based on NCSPA pipe storage capacity tables and represent approximate cubic feet of storage per foot of pipe length.
Pipe Storage Capacity Lookup Tool
Select a pipe size and corrugation profile, then enter pipe length to estimate stormwater storage capacity.
Storage values are based on NCSPA pipe storage capacity tables and represent approximate cubic feet of storage per foot of pipe length. Gallons are calculated using 7.48052 gallons per cubic foot.
Corrugated steel pipe is commonly used for underground stormwater storage because it provides efficient water storage in a durable, long-lasting system with a compact footprint. This lookup tool converts NCSPA pipe storage values into a fast, easy-to-use calculator for preliminary planning and design.
