Storage sized right the first time.
Tank and dam volumes, drawdown, turnover and freeboard so storage is sized for the demand. Built for designers and farm managers.

These figures come from the Tenselo engine. Every result Tenselo produces shows the inputs it used and the method behind it, so the work can be checked rather than taken on trust.
Why it matters on the job
Volume from real geometry
Batters, floor and depth resolved to an actual stored volume — not a rectangle guess.
Drawdown you can plan
Turnover and drawdown so the storage carries the demand between fills.
Freeboard & overflow safe
Freeboard and spillway sized so it holds the inflow without overtopping.
