Study Notes
Water Supply System
- Water supply system in a building ensures the availability of clean water for various purposes.
- Purposes of water supply include:
- Providing potable water to fixtures in buildings
- Sanitation (showers, laundry, toilets, basins)
- Cooking
- Gardening
- Fire protection
- Types of water supply systems:
- Direct supply system from main tank to all fixtures
- Direct supply to overhead tank system (indirect supply) and then to all fixtures
- Combined system: Direct pumping to overhead tank then direct to all fixtures
Direct Supply Systems
- Water is directly supplied to various floors of the building from the mains
- Suitable for buildings with a small number of floors (typically 2 to 5)
- Requires sufficient water pressure in the mains
Direct Supply to Overhead Tank System (Indirect Supply)
- Used when mains water pressure is insufficient for direct supply
- Water is pumped into an overhead storage tank (usually on the roof)
- From the storage tank, water is supplied to different floors by gravity
- Can directly supply fixtures without an overhead tank
Combined Systems
- In tall buildings, separate drinking and cold-water cisterns are advantageous
- These cisterns distribute the load of water storage throughout the building
- Pressure is controlled to ensure safe operation and limit pressure variations
Hot Water Supply
- Water heaters heat water
- Hot water supply pipes are located in building shafts
- Spaces requiring water are designed around the shaft to reduce travel distance of water pipes
Water Drainage System
- Water drainage systems manage and direct the flow of water and wastewater
- Includes pipes, gutters, and drains to ensure efficient removal of rainwater and wastewater
- Prevents waterlogging, foundation damage, and maintains a safe and sanitary environment
Types of Water Drainage Systems
- Sanitary Drainage System:
- Deals with the removal of wastewater from toilets, sinks, showers, and other plumbing fixtures
- Includes drainage pipes, traps, and vents that transport wastewater to the municipal sewer system or a septic tank
- Storm Water Drainage System:
- Designed to handle rainwater and surface runoff
- Consists of gutters, downspouts, and drainage pipes that carry water away from the building
- Combined Drainage System:
- Found in older urban areas
- Combines sanitary wastewater and stormwater into a single pipe network
Soil Pipes and Waste Pipes
- Soil pipes:
- Carry soiled water away from the home
- Designed to handle wastewater from toilets, urinals, and bidets
- Wider than waste pipes
- Waste pipes:
- Carry water from daily uses such as showers, sinks, dishwashers, and washing machines
- Separate from soil pipes
- Direct wastewater away from the home
