What is the correct order of the stages in the planning of a drinking water treatment plant installation?

• Feasibility Study, Preliminary Design, Final Design, Constructing of the Plant, Conceptual Design & Master Plan

• Conceptual Design & Master Plan, Preliminary Design, Feasibility Study, Final Design, Bench Scale & Pilot Plant Studies, Constructing of the Plant

• Preliminary Design, Feasibility Study, Final Design, Conceptual Design & Master Plan, Constructing of the Plant

• Final Design, Bench Scale & Pilot Plant Studies, Feasibility Study, Preliminary Design, Constructing of the Plant

Why is a Feasibility Study important in the planning of a drinking water treatment plant?

• It determines the final construction schedule.

• It evaluates whether the project is practical and viable before proceeding to detailed design.

• It is used to create the master plan.

• It is the last step before plant operation.

Which of the following is NOT typically found as a floating and suspended material in surface water?

• Branches

• Leaves

• Algal mats

• Iron and manganese

Which of the following is NOT one of the six factors considered in establishing the design criteria for water treatment systems?

• Design Life

• Facility Limits

• System reliability

• Distribution strategy

Environmental and regulatory standards are important in establishing design criteria for water treatment systems because:

• They ensure compliance with laws and protect the environment.

• They increase the cost of the system.

• They determine the cost of the facility.

• They reduce the reliability of the system.

Suppose a community reports a highly objectionable color in their drinking water. Based on the picture, which type of water quality issue is most likely responsible?

• Physical

• Chemical

• Microbiological

• Radiological

A public health official is investigating an outbreak of illness linked to drinking water. Which category of water quality should be their primary focus?

• Physical

• Chemical

• Microbiological

• Radiological

Why must processes and components with different design lives be brought to an equivalent life for economic comparison?

• To ensure a valid economic comparison

• To reduce the cost of materials

• To increase the speed of production

• To improve the appearance of the product

Suppose you are tasked with evaluating two process trains for a new facility. What strategic factor should guide your final selection according to the provided material?

• The process with the lowest environmental impact

• The process with the most advanced technology

• The process with the best economic evaluation

• The process with the shortest construction time

Why is it important to include provision for expansion in the layout of a water treatment plant?

• To allow for future increases in capacity

• To reduce the initial construction cost

• To minimize the need for maintenance

• To improve the taste of water
