Parallel Wiring

Image
For my house I have opted to go with parallel wiring than opposed to series wiring. It is much more commonly used within a home. It is a reliable method pf wring as failure does not affect all devices/bulbs. A parallel circuit is also a closed circuit where the current divides into two or more paths before coming back together to complete the full circuit. Here, the wiring is configured so that each device is in constant contact with the main circuit pathway. A parallel circuit has many such "off-ramp/on-ramp" loops, so that a failure in any single loop never shuts down the entire circuit. Outlets, switches, and light fixtures are wired in such a way that the hot and neutral wires maintain a continuous circuit pathway independent from the individual devices that draw their power from the circuit

Water Supply

Image
For my house I have went for an indirect cold water supply system as it can reserve the supply of water if mains fail. There is constant pressure on all taps, except the kitchen tap and there is also an overflow fitting fitted to storage tank to prevent water damage due to overflow.  The indirect cold water supply system directs the mains water coming into the house in two directions, one up to a storage tank or the cistern in the attic and the other to the kitchen tap. It is fed off to individual appliances from the cistern. The only outlet coming directly from the mains is the kitchen tap. This tap is the source of clean drinking water for the household. The tap is also the only high-pressure outlet in the system.  I have chosen the indirect hot water supply because it reduces stress on boiler due to regulated temperatures. There is no build up of limescale as the same water is being reused and radiators can be connected to the system. The indirect system is much more common...

Surface Drainage for surface water and foul water

Image
The two main places where surface water gathers are the roof and paved areas. Surface water has become more of a problem in recent years due to the increasing number of homes being built in urban areas. Siting buildings on previously undeveloped land means that the land absorbs less water than it would if there were no buildings, and this in turn increases the volume of surface water. Why I chose this system was because foul water is directed into the sewer system and piped to a treatment plant as it is soiled. The surface drainage will run off water which is kept clean so it is kept separate. It could possibly be stored in an underwater storage tank and reused for non sanitary purposes if the correct filters are used to clean the water of leaves and dirt. This system can be used for flushing toilets, watering plants etc but cannot be used for showers or tap water.
