Drainage Solutions for In-Ground Trampolines

Many people think that installing an in-ground trampoline is as simple as digging a hole and placing the trampoline structure inside, but that’s simply not the case. Not only do you need to plan for things like retaining walls and ventilation when installing an in-ground trampoline, but you also need to consider how to drain any excess water that might collect inside of your trampoline pit.

Do I Need a Drainage System for an In-Ground Trampoline?

The short answer is yes. Unless you live in an area with a very low water table, there is always a chance that your trampoline hole could fill with water during a storm. Instead of dealing with that scenario when and if it happens, it’s a much better idea to be proactive and create a drainage system when you initially install your sunken trampoline.

Drainage Options for In-Ground Trampolines

There are several ways to accomplish adequate drainage for your in-ground trampoline:

Temporary Drainage Pumps

If you don’t expect to have much rain based on the soil and climate in your area, a temporary type may be the best solution for you. With this solution, all you need is a small drainage pump and an extension cord. Simply plug the pump in, insert the inflow hose into the trampoline pit, switch it on and the excess water will be gone in no time.

Permanent Drainage Pumps

If you foresee water retention as something that could be an ongoing problem under your in-round trampoline, you might consider placing a permanent drainage ump into your pit during the installation process. These pumps go under your trampoline, connect to a permanent electric source, and require you to dig a small trench for the cable and outlet hose. They are typically turned on using a switch in your shed or garage or with a float switch that turns on automatically when the water rises to a certain level.


Often the easiest and most cost-efficient option, this drainage solution only requires you to dig a trench from the bottom of the trampoline pit and connect it to a nearby drainage ditch. After that, you can place a 4” drainage pipe into the trench and watch as water is automatically whisked away. 

Drainage Pits or Soakaway Holes

To implement this drainage solution, all you need to do is dig a small 2’x2’x2’ hole in the center of your trampoline pit and fill it with gravel. This hole, also known as a French drain, will soak up excess water and keep your trampoline pit nice and dry.
