Sewer Pipe Calculator
Sewer Pipe Calculator is a specialized hydraulic design utility for civil and sanitary engineers on iOS and Android.
The App DNA
What makes this app unique?
The app replaces manual Manning equation calculations and spreadsheet-based design checks with a portable, field-ready interface that propagates invert levels and validates sedimentation risk automatically.
For Civil and sanitary engineers, designers, and students working on sewer networks and storm drainage systems.
What does it look like?
Key features
Six specialized tools for calculating velocity, depth, flow, and slope using the Manning equation for circular pipes
Verifies tractive force against sedimentation risk with color-coded status indicators
Spreadsheet-style interface for accumulating flow and propagating invert levels across a full sewer line segment
How much does it cost?
The freemium model gates advanced design modules and documentation features behind a Pro upgrade to capture professional engineering value.
Velocity
Maintenance developmentperformanceopaqueShow more...
With two releases over the last several months, the app maintains a maintenance-level cadence of approximately one update every 2-3 months. Development is currently focused exclusively on performance and stability, as the latest release notes provide no indication of new features or content. The development trend remains stable but limited in scope, prioritizing technical upkeep over functional expansion.

Key takeaways for Sewer Pipe Calculator
Where is it heading?
Sewer Pipe Calculator remains in a stable but stagnant position, as the lack of feature expansion limits its growth beyond the initial user acquisition funnel. The current maintenance-only cadence suggests the developer is prioritizing stability over market share, which exposes the app to more agile rivals who can integrate modern cloud-sync or BIM-compatible workflows.
- The maintenance-only release cadence suggests the developer is prioritizing stability over market share, which limits growth beyond the initial user acquisition funnel.
- Stalled feature development leaves Sewer Pipe Calculator exposed to more agile rivals who can integrate modern cloud-sync or BIM-compatible workflows.
The SWOT
- Self-cleansing tractive force verification provides a technical barrier that standard calculators lack.
- Collector Designer workflow serves as a B2B hook for project-level design.
- Expansion into automated regulatory reporting for specific regional standards could increase B2B adoption.

Read the full takeBottom line
Sewer Pipe Calculator maintains a defensible niche through specialized hydraulic modeling, but the current maintenance-only cadence risks losing professional users to more active competitors. Prioritizing the Collector Designer workflow would lock in project-level engineering firms and justify the Pro tier pricing.
