Safety in a RWH system involves protecting those who install the system, users of the water, and anyone else (especially children) who may be in close proximity to the storage tank.

 Installation Safety

As with any new construction, the installer should follow safety precautions prevent any injury. This includes following rules with heavy equipment and using personal protective equipment (i.e. safety glasses) when using power tools. In addition, a water storage tank is considered a confined space, where available oxygen may be limited. If your installation includes going inside a confined space, seek guidance from the Occaptional Safety and Health Administration (OSHA). (This is a legal requirement for businesses with employees.)

Safety for the User

The main goal of safety for the user is good water quality. For a storage tank to maintain good quality water, it must not allow for any light penetration. Sunlight entering the tank causes algae growth. Also, the tank must be properly screened and secured so that no insects or animals can enter. For detailed treatment information, see the Treatment section.

Safety for Children and Others

Unintended access to a storage tank is a safety risk that must be prevented. The first step is making sure that the observation port (the large opening at the top) cannot be accessed by anyone. This may mean either having a tall tank or having a lock on the lid (see below).
