Navigating the Platform
Aquaticus has three main sections accessible from the navigation menu:
Projects
Manage your watershape projects, save calculations, and track project status from concept to completion.
Clients
Build a searchable database of your clients with contact information and associated projects.
Model
Access the unified engineering calculator with real-time results for all your pool calculations.
Projects
The Projects page is your central hub for managing all your watershape projects. Each project stores all calculation data, allowing you to save, revisit, and modify your work at any time.
Creating a Project
- Click the New Project button
- Enter a project name
- Select or create a client
- Add optional tags for organization
- Your project is created and ready for calculations
Project Features
- Status Tracking: Mark projects as "In Progress" or "Completed"
- Custom Tags: Create and assign tags to organize projects by type, location, or any criteria
- Search & Filter: Find projects by name, client, tags, date range, or status
- Timestamps: Track when projects were created and last updated
Saving Calculations to Projects
When using the Model page, you can save your calculations directly to a project. This preserves all input values and calculated results, allowing you to return and modify them later.
Tip: Use descriptive project names and tags to make finding projects easier as your database grows.
Clients
Build and maintain a database of your clients for easy project association and contact management.
Client Information
For each client, you can store:
- Client name
- Email address
- Phone number
- Address
- Notes (for any additional information)
Client-Project Relationship
Each project is associated with a client. From the Clients page, you can view all projects for a specific client, making it easy to see your history with each customer.
Model
The Model page provides a unified engineering calculator that computes all project data in real-time as you enter dimensions and specifications.
Interface Overview
The calculator is organized into collapsible sections:
- Basic Pool Info — Shape selection and dimensions
- Depth Profile — Shallow/deep depths and transitions
- Dig & Excavation — Overdig, wall thickness, gravel settings
- Concrete — Floor and wall thickness, waste factors
- Steel/Rebar — Bar patterns, sizes, and bond beam configuration
- Hydraulics — Turnover time, pipe sizing, returns and skimmers
Live Results
The Live Results panel displays all calculated values in real-time, organized by category. Click on any result to see the formula explanation, including:
- What the calculation represents
- The formula used
- Input variables and their current values
- How the result was calculated
Note: All formulas in Aquaticus have been developed and validated by industry experts, including partners at Watershape University.
Pool Shapes
Aquaticus supports four primary pool shapes, each with appropriate perimeter, area, and volume calculations.
| Shape | Dimensions Required | Perimeter Formula |
|---|---|---|
| Rectangle | Length × Width | 2 × (Length + Width) |
| Circle | Radius | 2 × π × Radius |
| Oval | Length × Width | Ramanujan approximation for ellipse |
| Kidney | Length × Width | ~1.2 × Rectangle perimeter |
Finish Thickness
The finish thickness setting accounts for plaster or other interior finishes. This affects:
- Finish Length/Width: Interior dimensions after finish is applied
- Finish Gallons: Actual water capacity (reduced from structural volume)
Depth Profiles
Choose from three depth profile types to match your pool design:
Standard Profile
The most common profile: shallow end → transition slope → deep end.
- Shallow Depth: Depth at the shallow end
- Deep Depth: Depth at the deep end
- Shallow Length: Flat section at shallow end
- Deep Length: Flat section at deep end
The slope length is automatically calculated based on the remaining pool length.
V-Shaped Profile
Edges are shallow with the deepest point at the center. Commonly used for lap pools or aesthetic designs.
- Left/Right Edge: Depth and flat length at each edge
- Center: Depth and flat length at the center (deepest point)
Uniform Profile
Flat bottom with consistent depth throughout the entire pool. Enter a single uniform depth value.
Tip: Floor slope length calculations use the Pythagorean theorem to account for the actual floor surface area, which is longer than the horizontal projection.
Pool Features
Add features to your pool design that affect volume, concrete, and rebar calculations.
Available Features
Steps
Corner steps with configurable risers (2-5), dimensions, and position. Default: 18"×18" top step with 12" treads and 9" risers.
Sun Shelf
Tanning ledge/Baja shelf with adjustable length, width, and depth below waterline. Default: 6' × 10' at 12" depth.
Bench
Seating bench with customizable length, width, and seat height. Default: 5' long, 18" deep, 18" seat height.
Feature Modes
- Simple Mode: Use preset configurations with position selection
- Advanced Mode: Full control over dimensions and steel patterns
Feature Calculations
Each feature automatically calculates:
- Water Displacement: Reduces actual water capacity
- Feature Concrete: Additional concrete volume needed
- Feature Rebar: Additional reinforcing steel required
Calculations
Aquaticus performs comprehensive engineering calculations across multiple categories.
Geometry
- Perimeter: Total edge length for bond beam, coping, and tile
- Floor Area: Surface area accounting for slopes
- Wall Area: Perimeter × Average Depth
- Total Surface Area: Floor + Wall area for finish estimates
- Average Depth: Weighted calculation based on depth profile
- Interior Volume: Structural volume in cubic feet
Excavation
- Dig Volume: Total excavation including overdig allowance (cubic yards)
- Gravel Area: Area requiring gravel bed (extends under walls)
- Gravel Volume: Drainage gravel needed (cubic feet)
- Gravel Weight: Ordering quantity in tons
Concrete
- Floor Concrete: Cubic yards with waste factor
- Wall Concrete: Cubic yards with waste factor
- Total Concrete: Combined floor + wall
Default waste factor: 20% for spillage and overages.
Steel/Rebar
Aquaticus calculates rebar for floor, walls, and bond beam with detailed breakdowns by bar size (#3, #4, #5, #6).
Rebar Configuration
- Cage Patterns: Up to 3 cages per section (floor/wall)
- Pattern Format: "#4 @ 12" OC" (bar size @ spacing on-center)
- Bond Beam: U-bar size, spacing, beam thickness and height
Calculations Include
- Linear feet (base calculation)
- Lap splices per ACI 318-19 standards
- Waste factor application
- Number of bars (based on 20' standard lengths)
- Weight in tons
| Bar Size | Weight (lb/ft) | Lap Splice |
|---|---|---|
| #3 | 0.376 | 20" |
| #4 | 0.668 | 25" |
| #5 | 1.043 | 32" |
| #6 | 1.502 | 38" |
Hydraulics & Filtration
Calculate flow rates, pipe sizes, and equipment requirements for proper water circulation.
Water Capacity
- Maximum Gallons: Structural capacity (Volume × 7.48)
- Finish Gallons: Actual capacity after plaster thickness
- Adjusted Gallons: Accounts for feature displacement
Flow Requirements
Default turnover time is 8 hours for residential pools. Commercial pools typically require 4-6 hours.
Returns & Skimmers
Aquaticus recommends quantities based on:
- Returns: Max 25 GPM per return, 20 ft perimeter spacing (minimum 2)
- Skimmers: Max 500 sq ft per skimmer, 55 GPM per skimmer (minimum 1)
Pipe Sizing
Pipe sizes are calculated using the velocity method with Schedule 40 PVC:
- Return Lines: Target velocity 6-8 ft/s
- Suction Lines: Target velocity 3-5 ft/s (lower to prevent cavitation)
Advanced Settings
Customize hydraulic parameters:
- Max flow per skimmer/return
- Max area per skimmer
- Perimeter spacing per return
- Min/max velocity ranges
Export & Reports
Export your project data for documentation, client presentations, or internal records.
What's Included
- Project details (name, client, dates, status)
- All input specifications

Coming Soon: Additional export formats and customizable report templates are in development for future releases.
