TACTICAL WATER PURIFICATION SYSTEM (TWPS)
PREPARATION FOR USE AND INSTALLATION INSTRUCTIONS
SET-UP OPERATION UNDER USUAL CONDITIONS
FLOATING INLET STRAINER AND ANCHOR DEPLOYMENT
If the raw water source is from a sandy beach location and if surf conditions or tide extremes make it
difficult or impossible to use the floating inlet strainer, the OISS should be deployed instead of the floating
inlet strainer. For OISS setup see WP 0008.
Deploy the floating inlet strainer and anchor as follows:
1. Carry the following items to the 1st raw water pump skid:
a. Floating inlet strainer.
b. The number of raw water suction hoses required to deploy the inlet strainer to the desired
location in the raw water source (up to thirteen 3 in. x 10 ft., green-banded suction
hoses).
c. Anchor.
d. Anchor tie-down rope.
WARNING
Health hazard. Do not attempt to use product water hoses to handle raw water or
raw water hoses to handle product water. When installed with the proper adaptors
as directed, the hoses cannot be interchanged. Failure to observe this warning
and mixing hoses could cause contamination of water resulting in serious illness.
NOTE
The floating strainer and anchor may be used in conjunction with the Ocean Intake
Structure System (OISS). If the OISS is to be used, refer to WP 0008, OISS Set-Up
Instructions, for the procedures for installing the OISS.
When deploying the floating inlet strainer, keep the following in mind:
- Two persons are required to deploy the inlet strainer.
- Place the inlet strainer in deep water at the center of narrow rivers.
- Place the inlet strainer as far from shore as possible in wide rivers.
- Place the inlet strainer as far out as possible at ocean beaches.
- Flat tidal beaches may require moving the pump according to tide conditions.
2. Assemble the anchor, rope, inlet strainer, and hoses on-shore as follows (see Figure 5):
a. Attach the shackle and pulley to the anchor eye and double the rope back so that the
rope length from the anchor to the free end is at least 150 feet.
b. Inspect the gaskets in the female ends of the hoses. Replace any damaged or missing
gaskets.
c. Always rinse off the hose ends with water to remove dirt and sand.
d. Connect the number of 10 ft., green-banded suction hoses to each other that will be
required to deploy the inlet strainer to the desired location in the raw water source.
e. Connect one end of the hose assembly to the inlet strainer. Install the 3 in. plug in the
other end of the raw water hose assembly. This traps air inside the hose that will allow
the hose to float until the inlet strainer is positioned at the desired location in the raw
water source.
f. Shackle the end of the rope to the inlet strainer eye and tie the free end to the suction
hose.
g. Carefully coil the rope to prevent it from tangling when the anchor is deployed.
