| Healthy soil needs water, but mains water is costly, treated, and often wasted on gardens. At Earthly Comforts, we want the Soil Builder’s Hub to demonstrate a smarter way: capturing and storing rainwater so we can reuse it to feed our soil systems. As many of my readers will know, Sue and I have been looking very deeply into water harvesting for the last few years, especially on Plot 17. Well, finally this winter we’ll be introducing IBC water harvesting systems there — and the Soil Builder’s Hub will be getting one too. |
| The Setup We’ll be installing a mounted IBC container (Intermediate Bulk Container) as the main water storage vessel. These are strong, reliable tanks that can hold 1,000 litres at a time. The system will include: Guttering and downpipes from a shed or cover roof to direct rain into the IBC. Mounted frame to keep the container elevated for gravity-fed flow. Taps and hose connectors for easy use around the Hub. Overflow system so excess water can run safely into the ground or another container. |
| Why It Matters Reduced mains use – less reliance on treated tap water, cutting costs and saving resources. Right water for the soil – rainwater is softer and more natural than tap water, better for microbes and plants. Climate resilience – stored water means we can keep compost bins, worm farms, and leaf kraals at the right moisture even during dry spells. Demonstration value – it shows clients how easy it is to integrate water harvesting into their own gardens. |
| How It Fits the Hub The water harvesting system will link directly to the rest of the Soil Builder’s Hub: Compost bins – a quick splash of rainwater keeps microbial activity thriving. Worm bins – worms need consistent moisture, and rainwater helps without the chlorine of tap water. Leaf kraal – occasional dampening helps leaves break down faster. Mulch bays – bark and chips can be pre-wetted before spreading, reducing initial dryness. |
| In short: every drop counts, and by harvesting rainwater we can make sure the Hub runs sustainably, without wasting treated tap water on soil systems that thrive best on rain. |
