Why Harvest Rainwater in Your RV?


There are many reasons why you might consider collecting rainwater in your RV. For one, it's a great way to supplement your water supply, which is especially important when you don't have easy access to water sources. Additionally, rainwater harvesting can help reduce your environmental impact by minimizing your reliance on municipal water sources.


Another benefit of RV rainwater harvesting is that it can save you money. Using rainwater for various tasks, such as washing dishes, watering plants, keeping your furry friends hydrated, and flushing the toilet can reduce your need for potable water. This means less trips to a local source and a lower annual cost to satisfy your water needs.


How to Harvest Rainwater in Your RV


Harvesting rainwater in your RV is a fairly simple process. Here's how to get started:


Install a rainwater collection system: To collect rainwater, you'll need a system that can capture the water and direct it into your fresh water tank or external reservoir. There are a few different options for this, including WildWater RV's patent pending line of products and solutions.


Prepare: When rain is in the forecast, make sure to attach your hoses and prep your system for catchment. If you're in a permanent location, you can simply leave your system set in place.


Prefilter the water (for non-potable uses): Before using your collected rainwater, it's important to filter it to remove any debris or contaminants. You can do this by using a simple filtration system, such as a fine mesh screen or a sediment filter.


Store the water: Once you've collected and filtered the rainwater, you'll need to store it in a tank for later use. Many RVers use their on-board fresh water tank, while others use collapsible water bladders or even smaller reservoirs.


Additional filtration (for potable uses): If you plan to shower, brush teeth or drink collected rainwater, than you should filter and/or treat it using an advanced filtration system or treatment solution. Ideally, ones that will significantly reduce or eliminate bacteria and contaminants.


Use the water: Congratulations! It's time to put your harvested rainwater to use!


Tips for Successful RV Rainwater Harvesting


To make the most of your RV rainwater harvesting system, here are a few tips to keep in mind:


Be mindful of local regulations: Some areas may have restrictions on rainwater harvesting, so be sure to check local regulations before setting up your system.


Keep your collection system clean: To ensure that your collected rainwater remains clean and safe to use, be sure to clean your collection system regularly and replace filters as needed.


Monitor your water usage: To avoid running out of water, it's important to monitor your water usage and plan accordingly. Consider using low-flow fixtures and taking shorter showers to conserve water.


Be prepared for emergencies: In the event of an emergency, it's important to have a backup source of water available. Consider carrying extra water or a portable water filtration system in your RV.


Final Thoughts


RV rainwater harvesting is a great way to conserve water, reduce your environmental impact, and save money. With a little bit of planning and some rain in the forecast, you can start passively catching rainwater to supplement your RV lifestyle!
