At the Grove, we do not have a hose nearby to water plants in the gardened area. Instead I bring buckets from home (it’s right next door) of used dishwater. Dishwater, wastewater not too full of other substances besides organic wastes dissolved, is quite nutritious and a way of giving back to Nature. What the city sewer systems do on a huge scale, I can do on a tiny scale with my simple system. Granted, I’m not about to start bailing out my toilet as well. The city is welcome to that!
It’s quite easy to create your own source of grey-water.
- Get two plastic wash basins for the kitchen
No matter what sort of sink you have, it’s possible to find something that will fit, and that you can empty easily into a nearby bucket for the garden.
2. Use one as ‘pre-soak’ for dishes
With a large single sink, hopefully both basins fit inside. If it’s a double sink, there will be less splash from placing one basin at counter level. This is where the plants get to taste your leftovers.
3. Use the other for soapy water.
Scrape as much loosened food residue as you can off the dishes before they enter the soap. This also cuts down on how much soap you use.
4. Rinse into the ‘pre-soak’ basin.
Rinsing is what uses the most water. Letting this basin fill quickly means more water for the garden bucket. When it’s full, scoop or pour it to that bucket. This is your grey-water. The amount of soap is dilute enough not to bother most plants.
5. The soapy basin becomes the new ‘pre-soak’.
When the dishes are done and you have finished wiping down here and there around the place, let the food-containing remainder sit and await new dishes. Don’t worry if it gets a bit scummy from living organisms between now and the next washing up. The garden loves microbes, and the soap will kill them when they are washed off the dishes later. Of course if it is too smelly, you may want to hasten it outdoors instead and start fresh. But otherwise,
6. Scrub the former ‘pre-soak basin well, let dry until the next washing up.
The reason for this is hygiene. Bacteria are either aerobic or anaerobic, depending on whether they are killed by the presence of oxygen. The anaerobic ones will all die from being dried out, meaning it will take less soap to kill those that remain when the time comes again for soap.
7. Deliver the nutritious grey soup to your plants.
It’s beastly hot out where I am just now, and the plants can get quickly stressed, especially if the nearby trees are using the majority of the soil moisture themselves, with their deep and established root networks. My little plantings are a mere peach-fuzz in comparison, and the surface, even mulched, gets thirsty at peak growing time.
Remember, Nature is good! and Nature is good. All else follows from that.
