Criterion 6.1.3.3 Waterproofing

Criterion text:
Underground and above ground unsheltered storage tanks shall be waterproofed to prevent water seepage.

Comments:
This criterion deals mainly with underground storage tanks. These are more common in commercial systems than the type of residential application systems that SRCC certifies.

Particular attention has to be paid to above ground unsheltered tanks to ensure that they are not damaged from external conditions.

Figure 1 shows a tank that was installed outdoors under a partial enclosure. As evident, the tank is not well protected on one side. Water damage to both the tank and system components can easily occur.

Figure 1

A special enclosure was constructed in Figure 2 to protect the tank from water damage and other environmental related problems. (Of course, the front door is normally closed.)
