Richmond gets its fair share of precipitation. Why not make good use of it? Harvested rainwater could come in handy, like in the event of an unexpected water crisis.
We’re here to decode the city’s guidelines about rainwater harvesting, help you capitalize on this resource + save money on your monthly bill.
What is rainwater harvesting?
Harvested rainwater is precipitation collected from a non-permeable surface (like your roof) and funneled into a designated vessel (like a rain barrel or cistern) before contacting the ground. At its simplest, this eco-friendly system is a DIY outlet for potable and non-potable water reuse.
Virginia’s code outlines four tiers of rainwater use, detailing exposure levels and regulations for various repurposing. Note: You will need a permit for Tier 4 reuse, intended for human consumption.
Why harvest rainwater?
With a harvesting system in place, you can recycle rainwater for non-potable purposes like watering indoor plants, soil irrigation, toilet flushing, laundry, and car washing. The best part: After set-up costs, it’s free. The best part: After set-up costs, it’s free. Bonus: You don’t need a permit for non-potable rainwater harvesting.
It’s an effort of sustainability at its core, but it’s also a method of preparedness; When rain isn’t in the forecast or in the case of an unfortunate water crisis (chilling flashbacks to January), you have a backup plan.
How do I start?
- Barrels, typically 50-60 gallons in size, are commonly placed below downspouts to collect roof runoff.
- Cisterns can support the rainiest seasons and can contain up to 1,000 gallons.
- Rain chains typically support smaller collection and direct water from the gutter to the ground. They’re also a cute decoration.
- Remember: Potable reuse intended for human consumption will require a permit.
