My first presentation is about the planning aspects. They are many planning aspects that can be choose such as transportation, pedestrian walk, waterfront development, urban sprawl, slump area and sustainable development.
I choose the topic of Sewerage system. I know its sound awkward especially when we are talking about the planning aspects. However, I do believe that this topic is also important in planning aspects, especially when we are designing a new city which a good sewerage system is vital.
The Sewerage System
The system of pipes used to collect and carry rain, waste water and trade waste away for treatment and disposal is called the sewerage or the waste water system.
There are three types of sewerage systems:
- Foul sewers – carry waste water, that is water that has been used for cooking and washing, waste from toilets and from trade premises to our wastewater treatment works;
- Surface water, or Storm sewers – carry rainwater from roofs, paved areas, pavements and roads. Surface water sewers generally flow into streams, rivers or watercourses;
- Combined sewer – this is a single pipe system which carries both wastewater and surface water to our wastewater treatment works. These are often found in older town centre systems. Single pipe systems are no longer designed or constructed.
It is an offence to discharge foul sewage to a sewer designated for surface water or surface water into a sewer designated for foul sewage.
All new sewerage systems should be designed on separate foul and surface water (storm sewers) systems.
