Construction engineering
Electricity is brought to a building by underground cables. When the electricity load is small and total current drawn is less than 30 amps, only single phase and a neutral are sufficient.
BUILDING SERVICES
1. WATER SUPPLY AND DRAINAGE IN BUILDINGS
The
plumbing systems required for water supply and drainage in buildings are:
(i)
Rain water drainage system above the ground level
(ii)
Water supply system inside the building
(iii)
Wastewater drainage system above the ground
(iv)
Drainage system below the ground carrying foul water to septic tank or the
public sewer.
Water
discharged from waste appliances is called waste water or grey water. Water discharged
from soil appliances such as closets, urinals, etc. is called sewage. The waste
water from sewage is called foul water. The waste water and foul water have to
be collected safely and disposed of from a building.
2. ELECTRICITY SUPPLY TO BUILDINGS
Electricity
is brought to a building by underground cables. When the electricity load is
small and total current drawn is less than 30 amps, only single phase and a
neutral are sufficient. However, when the load is heavy for operating equipment
such as air conditioner, heaters, pump, washing machine, etc., three phase
connection is necessary. In this way, the load drawn among the three-phases is
distributed.
