About this app

Calculate water level from volume for drainage pits and tanks.

This app calculates the required water level by reverse-calculating from the target water volume. It supports drainage pits with frustum (sloped) shapes and footing projections, providing highly accurate results.
It helps with sanitary plumbing shop drawings, drainage pit design, and improves the efficiency of plumbing system planning and verification.


【Recommended for】

・Engineers who need to calculate the water level of drainage pits
・Users who need to determine water level from a specified volume
・Designers working with frustum (sloped) drainage pits
・Engineers who need volume calculations considering footing projections
・Professionals creating shop drawings for sanitary plumbing systems


【Key Features】

■ Reverse Calculate Water Level from Volume
Automatically calculates the required water level from the specified effective water volume.

■ Supports Frustum (Sloped) Shapes
Accurately calculates water level and volume for frustum (sloped) drainage pits.

■ Considers Footing Projections
Automatically accounts for the volume reduction caused by footing projections.

■ High-Precision Calculation
Uses an iterative calculation method to determine the water level with approximately ±0.5 mm accuracy.

■ 3D Preview
Visualize the entered dimensions and calculated water level in an interactive 3D view.


【Applications】

・Drainage pit design
・Sanitary plumbing shop drawing creation
・Plumbing system design
・Building services engineering
・Water level verification
・Volume verification
