Water Treatment and Distribution L3P1,U5LO1.5.p2

What is the main purpose of rapid sand filters in water treatment?

• Maintain water pressure without a pump

• Remove algae and iron from raw water

• Remove floc after the flocculation process

• Remove manganese from raw water

How is water distributed in the gravity distribution method?

• By gravity from a high ground reservoir

• By using a water tower

• By using a pressure vessel

• By using a pump

Why is pumping necessary in the pumped distribution method?

• To overcome insufficient pressure from the main supply

• To distribute water via gravity

• To remove floc after the flocculation process

• To maintain water pressure without a pump

What is the purpose of a water tower in the pumped distribution method?

• To distribute water via gravity

• To maintain water pressure without a pump

• To overcome insufficient pressure from the main supply

• To remove manganese from raw water

Where is the water held in the pumped distribution method before distributing to the water network?

• In a chlorinating house

• In a slow sand filter

• In a settlement tank

• In a service reservoir on a tower
