1.1Domestic Sewage
What we have learnt
- Domestic sewage comprises wastewater from residential and commercial facilities, while stormwater is rainwater runoff.
- The design of sewerage systems must consider gravity flow and maintenance needs to ensure efficient sewage management.
- Effective treatment processes can involve aerobic and anaerobic systems, with recycling of treated wastewater being vital for conservation.
Key Concepts
- -- Domestic Sewage
- Wastewater generated from households and commercial establishments, including toilets, kitchens, and bathrooms.
- -- Storm Water
- Rainwater runoff managed to prevent flooding and pollution, originating from various impermeable surfaces.
- -- Sewerage System
- A network of pipes, pumping stations, manholes, and treatment units designed to manage sewage effectively.
- -- Aerobic Treatment
- Wastewater treatment that occurs in the presence of oxygen, facilitating the biological oxidation of organic matter.
- -- Anaerobic Treatment
- Treatment without oxygen that decomposes organic material to produce biogas, such as methane.
- -- Recycling of Sewage
- The process of reusing treated wastewater for various applications like irrigation and industrial uses to conserve water.
