The Kitchen Fort Water System
The kitchen fort, delivered in 2023, is a marvel in camp automation, allowing us to bring a commercial-quality working kitchen to playa and start using it without any setup. However, we're still learning about the best way to hook it up to water.
Fresh Water
There are two separately plumbed fresh water systems: one for sinks and one for the ice maker.
Each system has:
- a hose attachment outside for connecting water to the system
- two tanks per system under the bottom of the trailer to store water
- a little Shur-Flo pump inside the trailer that can pump water up from the tanks to pressurize the system
- a shut off valve inside the trailer that connects or disconnects the tanks and pump
In 2023 and 2024, our idea was to fill the water tanks every time they ran out of water. We thought this was a nice idea because it got the water team involved every once in a while and avoided the risk of the kitchen using up all of our camp water by mistake.
Besides the obvious inconvenience of filling the tanks again and again, the other problem with this system is that while you are filling the tank, when it gets to the top, it just starts spilling on the ground. So you have to stand there watching while you fill it.
2025 Improvements
For 2025, we're going to try bypassing the food fort's own water tanks and pumps. Instead we'll just provide pressurized water to the kitchen at all times. This can be done by connecting hoses to both the sink and ice water inlets and turning off the shut off valves that let water get down into the tanks. We would also unplug the two fresh water pumps inside the kitchen from power.
The way we'll set this up:
- The SSS 500 gallon tank will be set up right next to the food ford. It has a pump and a 15' hose.
- from the output of that hose, supplied by SSS, we'll connect
- to a hose splitter with shutoff valves
- to two smaller hoses
- each of those hoses goes through a check valve (to prevent backwash)
- and also through a water meter (so we can monitor usage)
- to the two hose inlets (one for ice and one for fresh water) on the side of the food fort.
Ice Maker
The ice maker system is just like the fresh water system, with its own tanks and pump and shut off valve. In 2023 and 2024 we were underwhelmed by the amount of ice this system could produce (it was nothing close to what it should have been able to produce based on specs) and overwhelmed by the amount of clean but undrinkable water that it dumped on the ground through an open spout under the trailer as a part of it's too-frequent "clean" cycle. In 2025 we want to give it one last chance by keeping it connected to pressurized water so it never runs out of water to see what it can produce.
Grey Water
There are grey water tanks under the kitchen which fill up about once a day. In. 2024, we pumped this water across about 100' to a grey water tank supplied by SSS.
The waste spout of these tanks is a 1.5" ID threaded outlet. It is probably about 9" above the ground.
For 2025 the official plan will be to put the SSS tank right next to the kitchen, and it will be exclusively used for kitchen grey water. The SSS tank is about 17½" high with input from the top:
To pump the water from the Food Fort tanks to the SSS tank, we'll connect a Valterra T01-0094VP or Valterra T01-0091VP (ordered) to the 1.5" outlet, and then from there a small length of garden hose, to a transfer pump that can pump the grey water up to the SSS tank on demand. We are going to purchase a Milwaukee cordless transfer pump which runs on the same batteries as our impact drivers; with that connected it should take about 10 minutes to completely empty the food fort.
