How to make and use a Rain Collector in Project Zomboid

Project Zomboid is a survival game where you need to stay alive for as long as possible. To do this, you will need to maintain your hunger and thirst levels, but because of the random nature of Project Zomboid, finding food and water isn’t always easy.

To make sure that you have a steady source of drinking water, you can make a rain collector, which will collect rainwater when it rains. This guide will show you how to make a rain collector in Project Zomboid, and how to use it.

How to make a rain collector in project zomboid ?

There are 3 versions of Rain Collector:

The smaller Rain Collector Barrel can hold 160 units of water, while the larger Rain Collector Barrel can hold 400 units of water. There are also metal barrels that can be found around the Louisville military camp that can hold up to 800 units of water, etal barrels cannot be made without a mod installed.

To make a Rain Collector Barrel in Project Zomboid, You will first need to have level 4 Carpentry(the larger collector requires level 7 Carpentry), and following items:

Ingredients4 ×  Plank
4 ×  Nails
4 ×  Garbage Bag

Once you have all the Ingredients, and with a Hammer in your hand, you can craft a Rain Collector Barrel through the Build Menu(Carpentry->Furniture).

Where to placed the Rain Collector?

You can place a rain collector anywhere outdoors to collect rainwater, But in order for plumbing to work, you will need to have the rainwater collector barrels at one floor above the sink.

How do you attach a rain barrel to a sink in Project Zomboid?

After making the rainwater collectors, there was a problem that the sink could not be connected and water could not be drawn from it. Through some searching, many answers and proposed methods were found but none of them solved the problem. So, after testing, I summarized some conclusions about using the rainwater collector.

1.Sink has to be inside if it’s outside plumbing option won’t show up.

Incomplete walls and Plumbing options will not show up

In order to be classified as inside, the sink must be surrounded by walls. This means that the sink must be enclosed by a wooden doorframe, wooden frame, or other similar structure.

Classified as inside

The inside of a room can be determined by the sudden change in temperature. When you walk into a room, the temperature change can be saw immediately. The inside of a room is usually warmer than the outside, so the temperature change would be a decrease.

2.You will need to have the rainwater collector barrels at one floor above the sink.

The red tiles in the screenshot correspond to the location of the downstairs sink, and the outer circle of blue and green tiles corresponds to the location where the rainwater collector can be placed. The rainwater collector cannot be placed in the middle of the red tile.

The screenshoot shows a schematic of the location.

3.Plumbing a Sink with the pipe wrench

You should see the plumbing option if you did every step correctly.

After you successfully plumb the sink, You can test the sink by adding water to the rainwater collector. To do this, simply fill a container with water and pour it into the rainwater collector. If the sink drains properly, then the placement is successful. If not, you may need to adjust the placement of the collector or the sink itself.


A rain collector is a simple and effective way to collect water for use in Project Zomboid. By following the steps outlined in this article, you can easily make and use a rain collector to help you survive in the zombie apocalypse.
