Study Notes
Stormwater and Sewage Management
- Stormwater Quantity is estimated during rainfall events to determine peak flow.
- Dry Weather Flow (DWF) represents the average flow in sewer systems during dry conditions.
- Sewage Flow fluctuates based on factors like population and time of day.
Flow Systems of Sewerage
- Separate System keeps stormwater and sewage flows distinct.
- Combined System collects both stormwater and sewage in the same system.
- Partially Combined System uses a combination of separate and combined systems.
Layouts of Sewerage System
- Design Considerations for layout include topography, population density, and land use.
Capacity of Sewers
- Design of Sewers involves considering anticipated flow, material choice, and environmental factors.
Laying Out of Circular Sewers
- Boning Rod and Sight Rail Method is used for aligning and grading sewers.
Testing and Maintenance of Sewers
- Regular inspections and maintenance procedures are crucial to prevent blockages and ensure functionality.
