The topic of tonight’s episode of the brilliant MBC show ‘khawatir’ was about water conservation. They showed how much water was being wasted during ablution. Changing attitudes towards consumption would be great, but to push this even further we need to reuse the water that is collected through the drain.
This waste water is pretty much clean greywater that we can use directly for irrigation. Here’s a study of testing done on ablution wastewater that shows that it can be used safely for irrigation. Under every ablution space there should be a water tank that collects all the water that’s used after ablution. This water is then pumped out at regular intervals to irrigate a garden surrounding the mosque, preferably growing edible plants. This would help reduce the temperature of the space, grow some food and avoid wasting water.
