Rainwater Systems

What are the two important factors to consider with the roof area in rainwater systems?

• Slope and material of the roof

• Color and design of the roof

• Height and width of the roof

• Age and condition of the roof

Which of the following is an important factor to consider with the roof area?

• The color of the roof

• The actual size of the roof area

• The material of the roof

• The number of windows

How does the roof area affect the amount of rainwater collected and the velocity at which the water enters the guttering?

• Larger roof area collects more rainwater and increases water velocity.

• Smaller roof area collects more rainwater and decreases water velocity.

• Larger roof area collects less rainwater and decreases water velocity.

• Roof area does not affect rainwater collection or water velocity.

What is the function of a running outlet in a rainwater system?

• To collect rainwater from the roof

• To direct rainwater to the drainage system

• To store rainwater for later use

• To filter debris from rainwater

The position of the running outlet is usually based on the location of which part of the property?

• Drain gulley

• Kitchen

• swimming pool

• Garage

True or False: The more outlets on the system, the less distance the rainwater has to travel in the gutter and the greater discharge efficiency the system has.

• True

• False

What is the purpose of a rainwater outlet in a rainwater system?

• To collect rainwater from the roof

• To filter debris from rainwater

• To direct rainwater to the drainage system

• To store rainwater for later use

In the diagram of the rainwater system, where does the rainwater outlet lead to?

• Surface water sewer in the road

• Inspection chamber

• Roof

• Garden

What should you check to find out the flow capacity of a running outlet design?

• The material of the outlet

• The diameter of the outlet

• The color of the outlet

• The brand of the outlet

How can you determine the number of outlets a roof line may require?

• By calculating the roof area and slope

• By considering the number of rooms in the house

• By checking local building codes

• By estimating the number of electrical appliances
