2. Children should be discouraged feom playing near the job
3. Barricades should be put up on the curb side of the trench to limit
accidental access by pedestrians
4. All operators must wear gloves, hard hats, and steel toed shoes
5. Easily visible construction signs, guards, lighting, and flangers
should be provided where needed for the protection of the public

What safety precautions must be taken during the installation of pipe?
1. Leaking joints must be repaired or adjusted
2. Children should be discouraged feom playing near the job

, What are the limitations of compound water meters?
1. Not suited for locations with widely varying flows where accurate low flow
measurements is needed
2. Large and cumbersome
3. Expensive
4. Accuracy drops during the changeover from low to high and high to low flows
5. Loss of head from friction is higher than in high flow meters
What benefits can distribution storage provide?
1. Chlorinated water may be held in covered distribution reservoirs to provide an
extended contact time for effective disinfection
2. Power costs can be reduced by pumping only during off peak hours
3. Reservoirs may serve as sand traps to allow the settling of sand and
suspended solids in the water
4. Water from various sources can be blended together in the reservoir to
provide water of consistent and acceptable quality to the consumers
5. Uncovered reservoirs increase protection against surface contamination
Which items are important considerations when selecting a type of pipe for a
specific installation?
1. Cost of the installation and the pipe
2. Water pressures and external pressures the pipe must withstand
3. Corrosive conditions of the soil and water
4. Record keeping requirements for the pipe material
5. Administrative costs for pipe testing
