13. Product Tank
The product tank has a capacity of 1000-gallon and is used to stored product water before distribution. It can
serve as a reservoir for batch treating the water in case of chemical pump failure. It has "POTABLE WATER
ONLY" stenciled on the sides.
14. Distribution Pump
The distribution pump is used to supply product water at a rate of 10-gpm through a nozzle. The pump has no
recirculation to the tank and therefore to be turned on only when distributing. The nozzle is to be kept off the
ground by using the Service pump module frame.
PROCESS AND EQUIPMENT FAMILIARIZATION
The understanding of the equipment and processes associated with the LWP is critical in troubleshooting and
becoming an efficient operator. This section will explain the unique equipments and processes of the LWP.
SPOOL PIECES
The LWP employs spool pieces to allow the connection of hoses and tubing to the 1000-gallon tanks. If
necessary, these spool pieces can be bypassed by draping the hoses directly into the tanks. There are
four spool pieces: an inlet and an outlet for the settling tank and an inlet and an outlet for the product tank. They
are stored inside the COEI boxes. The descriptions of these spool pieces are as follows.
a. Settling tank inlet spool piece
This is the only spool piece with the flow indicator. It also has a coagulant injection fitting and a
static mixer right down stream from it to allow mixing of coagulant with the incoming raw water.
See Figure 4.
