Question:

You have been asked to maintain a garden. How will you minimise the use of water?

Answer:

When I was told to maintain garden, I will minimize the use of water using the drip irrigation method. In drip irrigation method, water is supplied directly to the plants using narrow pipes that reduces the loss of water. Then I will check the leakages in the water pipes and arrange small pits or digs for rain water harvesting. So that the collected rain water will be used later for the various purposes. To maintain a garden’ grass or plants, water is necessary.

Steps should be taken to maintain a garden and minimise the use of water are as follows:

  1. You should not water plants through pipes because it wastes a lot of water.                                                                                                                              2. You should use drip irrigation system to conserve or save water.                                                                                                                                              3. Do not give excess amount of water to plants.                                                                                                                                                                              4. You can reuse old water and rain water or the waste water of RO that is released in the excess amount.                                                                              5. Plant flowers that need less water for the growth.
