51.7.5. Checking pipe gradients and blockages

Try these first

1. 1.

   What is a pipe gradient?

   Hint

   Think about how slopes affect movement.

2. 2.

   What indicates a blockage in drainage systems?

   Hint

   What would you notice if a drain isn’t working?

3. 3.

   What is the role of pipe gradients in drainage systems?

   • Facilitates water flow
   • Causes blockages
   • Requires constant repair

   Hint

   Think about the need for pipes to carry water away efficiently.

4. 4.

   Blockages in drainage systems can be caused by debris. True or False?

   • True
   • False

   Hint

   Consider what might naturally happen in any outdoor system.

5. 5.

   Design a drainage maintenance plan for a 50-acre irrigation field, detailing how often to check pipe gradients and what specific actions should be taken.

   Hint

   Consider the scale of the field when determining how often checks should occur.

6. 6.

   Evaluate the consequences of not addressing identified blockages in a drainage system. What strategies would you recommend to mitigate this risk?

   Hint

   Think about the long-term effects of water not being able to drain away.
