Drainage Tank Water Level Assistant
The Inverse Lookup Tool for Slope and Footing Calculations
This app is an inverse calculator designed to determine the required water level based on your target effective water volume. It is specifically engineered to handle complex drainage tank geometries, including frustum-shaped slopes and footings.

Challenges Solved
Difficulty in Manual Inverse Calculation: Calculating the water level from a specific volume in a frustum (sloped section) is mathematically complex and time-consuming.

Complex Volume Deductions: Accounting for volume displacement caused by footings makes manual calculations incredibly tedious.

Key Features
Accurate Volume-to-Level Calculation: Simply input your required water volume, and the app instantly calculates the precise water level.

Full Support for Complex Slopes: Specifically handles pit slopes (frustum shapes) where the height is usually difficult to determine. It accurately processes a three-layer structure: the sump pit, the sloped section, and the wall section.

Footing (Volume Deduction) Integration: Automatically accounts for footings that make manual math nearly impossible. The app precisely subtracts volume displacement based on your structural inputs.

High Precision Engine: Powered by a sophisticated binary search algorithm, the tool performs iterative calculations to ensure results with an extreme precision of ±0.5mm.

Intuitive 3D Preview: Instantly visualize the tank geometry and water surface level in 3D based on your dimensions.
