This guide covers the core workflow for designing sewage networks in CivilCAD

Before designing a pipeline, you must have an active surface (DTM) to define your elevations.

If you haven’t created a surface yet, Follow this link to How to Create a Surface.
  1. Step 1: Create a Support Layer
    Create a new layer for your geometry. This keeps your design organized and prevents it from merging with other site data.
    • Action: Create a new layer in your CAD environment.
    • Sample File: You can use the pre-configured layer: CU-SSWR-SPRT.
  2. Step 2: Plan Your Flow Direction
    You must identify the "Low Point" of your system before you draw a single line
    Pro Tip: Work from Low to High Always start planning from the lowest elevation (the outlet) and work your way up to the highest point. This ensures you are designing with gravity flow in mind from the very beginning.
    • Use the Pick Height tool to click on the surface and see the exact elevation at any point.
  3. Step 3: Draw the Pipeline Centerline
    Define the pipe's physical path using Polyline commands- Create segments according to your guidelines. Each vertex will become a manhole.
    • Use the Polyline commands (the same in your CAD environment) to draw the outline.
    Pro Tip: Main Line First Focus on designing the Main Sewage Line before adding secondary lines/branches.
  4. Step 4: Open the Pipelines List
    Go to the top menu, select Pipelines, and click Pipelines List.
    A new window will appear on the right side of your screen. This interface is where you define the identity of each pipe, including its name, type (e.g., Sewage), and profile shape (e.g., Round).
  5. Step 5: Define Your Pipelines
    Click the first row and enter the names and types for the pipes you drew in the "SPRT layer".
    • Pipeline Name: Enter a unique ID for each line.
    • Type: Select Sewage from the dropdown.
    • Pipeline Profile Shape: Choose the shape (e.g., Round).
    Pro Tip: Use Naming Hierarchies Create meaningful names that reflect the pipe's purpose.
    • Sample File Example: SW-M1 (Sewage Main 1) or SW-S1 (Sewage Secondary 1).

Unit control

Use this to define units for Diameter, Manhole size, and Wall thickness. Read more below.

Understanding Units Control

The Units Control settings allow you to define the measurement scales for your infrastructure components. Setting these correctly ensures that your pipeline data remains consistent across all reports and calculations.

You can set specific units for each element based on the Pipeline Type (e.g., Sewage, Water, Drainage).

Default Settings:

In most projects, sewage pipelines standard units are:

  • Pipe Diameter: Measured in mm (e.g., 600 mm).
  • Manhole Size/Pop: Measured in cm (e.g., 200 cm).
  • Wall Thickness: Measured in mm.
Always verify your units before entering data in the Layout window to avoid scaling errors in your 3D model.
