Study Notes
Building Drainage Terms
- Effluent: Wastewater discharged from a building, including sewage and other waste.
Purpose of Drainage
- The primary purpose of drainage in building projects is to remove wastewater and rainwater efficiently and safely.
Building Regulations (2010): Part N
- Above-ground drainage systems: Emphasizes the importance of proper design and installation to prevent leaks, blockages, and odours.
Soil and Waste Pipe System
- Carries wastewater from fixtures like toilets, sinks, and baths to the main sewer system.
Conveying Effluent to Sewers
- Ensures that wastewater is transported away from buildings efficiently and safely, preventing contamination and health hazards.
Drainage System Types
- Not included: Specific mention of all drainage system types, such as single stack, two-pipe, and combined drainage.
Above-ground Drainage System
- Should consist of:
- Soil and waste pipes
- Vent pipes
- Traps
- Access points for maintenance
Vent Pipes
- Provide ventilation for the drainage system, preventing pressure buildup and siphoning of water from traps.
Single Stack vs. Two-Pipe System
- Disadvantage of single stack: Potential for cross-contamination between waste and vent pipes.
Essential Part of Building Construction
- Drainage system is a vital component of any building; its proper design and installation are crucial for health and safety.
Risks of Unsound and Leaking Drains
- Potential for:
- Water damage to the building
- Health hazards due to sewage backup
- Unpleasant odours
Separate Drainage System
- Involves separate pipes for foul water (sewage) and surface water (rainwater).
Combined Drainage System
- Advantage: Single pipe system, less complex and cost-effective compared to separate systems.
Drainage System Layout
- Aim to minimize sharp bends and long runs in the piping for efficient flow.
Straight Line Pipe
- Facilitates smooth flow of wastewater through the drainage system.
Combined Drain
- Single drain for both foul and surface water, suitable for smaller buildings.
Water Pooling
- Term: Collection
Water Vapor to Liquid
- Process: Condensation
Liquid to Water Vapor
- Process: Evaporation
Water Falling from Clouds
- Process: Precipitation
Subsurface and Surface Water Runoff
- Term: Runoff
Water Evaporation from Plants
- Process: Transpiration
Water Treatment Processes
- Term: Water Treatment
Earth's Surface Water
- Main source: Oceans
Earth's Water Resources
- Ocean's contribution: 96.5%
Saline Water
- Percentage: 96.5%
Storage Accumulation of Water
- Term: Collection
Earth's Freshwater
- Type of water: Groundwater
Groundwater
- Percentage of Earth's freshwater: 0.9%
