Water Supply System Components 1. Water Supply Sources
2. Processing or treatment facilities
3. Means of Moving the water
4. Water Distribution
Water Supply Sources Supplied from natural fresh water sources such as wells, springs, rivers,
lakes, ponds, and the ocean.
Adequate Water Supply Sources Must be capable of supplying the water needed for fire protection in
addition to domestic requirements
Processing or Treatment Facilities 1. Water must be processed to remove impurities and minerals.
2. Before water can enter distribution system, it must pass through these
facilities.
Means of moving the water 1. Gravity
2. Direct Pumping
3. Combination

Gravity Systems (Moving the water) Deliver water from the source to the distribution systems without pumping
equipment.
Direct Pumping Systems (Moving the water) Supplied directly by system of pumps rather than elevated storage tanks.
Combination Systems (Moving the water) Use a combination of both gravity tanks and direct pumping process to
provide adequate pressure.
Water Distribution Consist of 3 different types of water mains.
1. Primary Feeders
2. Secondary Feeders
3. Distributers
Primary Feeders Large pipes that move large quantities of water and supply smaller
secondary feeders
Secondary Feeders Intermediate pipes that interconnect with he primary feeder lines to create a
grid.

, Fire Suppression 1.pdf Fire Suppression 1.pdf Fire Suppression 1.pdf
Distributers Small water mains that serve individual fire hydrants and commercial
consumers.
Fire Hydrant Types 1. Dry Barrel
2. Wet Barrel
Dry Barrel -Installed where freezing conditions are expected.
-Main valve holding the water is below the frost line underground
preventing the water from entering the hydrant barrel
-When hydrant is closed, barrel is drained through a drain valve at the
bottom of the hydrant.
-Must be completely open or closed to avoid erosion around the barrel
from the leaking drain valve.
-When hydrant is shut down, verify the water left in the barrel is draining out.
Dry Barrel Test Draining Procedures -Flow water from hydrant then close hydrant completely (until resistance,
then back quarter turn)
-Cap all discharges except one 2 1/2 discharge
-Place palm over open discharge
-should be slight suction/vacuum from draining.
