Design of Sanitary Sewage Collection Network

In this course I would like to teach you simple method of Sanitary Sewage Collection Network design. After this course you will be able to confidently use excel sheets in design of accurate and economic Sanitary Sewage Collection Network.

The course consists of 4 sections:

Section 1: Introduction about Sanitary Sewage Collection Sewers, and about the structures and components of the course.

Section 2: Basic Considerations in the Design of Sewers includes:

1. Project area

2. Design Period

3. Population Density

4. Field Work

5. Final Connection Point

6. The Manholes 6.1 Manhole structure 6.2 Drop Manhole 6.3 Manhole Locations and Spacing

7. The Trench

8. Alignments and Flow Directions

9. Numbering of Lines and Manholes

10. Pipe Materials

11. Design Sewage Flows

12. Flow Formulas

13. Partial Flow

Section 3: Design Criteria includes:

1. Minimum Size

2. Minimum and Maximum Velocities

3. Minimum and Maximum Slop

4. Sewer Depth

5. Minimum Cover

Section 4: Design of Sanitary Sewers by Excel Sheet includes:

1. Location

2. Population

3. Design Flow

4. Sewer Size & Slop

5. Full Velocity (Vf) & Full Flow (Qf)

6. Partial Flow Percentages (Q/Qf, V/Vf, d/D)

7. Actual Velocity (V)

8. Sewer Layout (Ground Surface Elevations & Sewer Invert Elevations)

9. Manhole Depths

In this course the excel sheet will be used in the design, because excel sheet simplify the calculation due to the relationships between the cells are by equations so when you change any value, all calculations of design will be automatically changed. You can use the same excel sheet of design, just you have to insert your input data of and you will get the results, but just you have to check the standard ranges and the criteria that explained in the course.
