How do I get freshwater in my Tiny House or RV?

Connecting a tiny house to freshwater is easy. You need a freshwater source, storage, and purification.

Tip: use fresh water from natural sources like groundwater, lakes, rivers or rainwater. 

Figuring out which water system will fit your tiny home best may seem like a stressful task, but it’s actually more straightforward than you’d expect.

Hooking up a tiny house to freshwater is easy. First of all, you need a fresh water source. This could be groundwater, lakes, rivers or rainwater. Also, you can source water from a town water line, but that depends on how remote your location is.

RV Hookup

This method is the least hassle. Those who plan to move around frequently should plan ahead to travel places with potable water sources. To ensure that the water is safe to drink on any location - a built-in purification system can come in handy. Tiny houses that stay in one location can hook up through water through an RV hookup, which includes an underground water source with a pedestal that feeds water into sinks and other faucets. If there are water tanks in your tiny house, they can be filled with potable water via a hose.

You can also have a water truck come and fill up your water tank, although that's a more expensive solution. To fill the fresh water tank, you'll use the water inlet located on the exterior of your tiny House RV. A water tank of at least 200 liters is recommended to supply two people for 4 days. 


You may choose to install a tank into your tiny home. In this system, you will fill the tank in your home manually, via a hose or other mechanism, and then the pump will circulate the water throughout your home. You will need an electric source in order to circulate the water. This is a great option for those that want their tiny home to be able to live off the grid. With an alternative energy source like solar panels, you would not need to connect to a traditional power source, which makes this option a highly sustainable choice

The biggest challenge here is to control the quality of the water. The above-mentioned methods ask for transportation of the water and stationary water - in which contamination is more likely. Also, the hose that you'd use to fill up the water tank can be full of bacteria because it is not used on a frequent base. To make sure, no matter where the water is coming from, that it is safe to drink - a high flow rate purifier is recommended with at least 200 liters per hour.
