2.2 Filling outside of the tank surround
Excavated soil or other material can be used as long as it is sufficiently stable and water
permeable.
Base course for the version suitable for traffic
Size 2/45 particles must be used.
2.3 Filling and compaction methods
2.3.1 The filling and compaction methods to be used are described in Section 3 (Installation
Guide).
2.3.2 Methods to be avoided include adding water. Adequate compaction is not achieved and
the mixture of particle sizes comes together in such a way that the packing is unstable.
2.4 Pipes
2.4.1 The inlet supply pipe should be laid with a downward gradient to the tank greater than 1%
2.4.2 (Only rainwater harvesting.) An overflow pipe or outflow pipe must have a steeper gradient
away from the tank than the supply line to the tank.
2.4.3 (Only rainwater harvesting.) The supply pipe must be set up so as to prevent flooding in a
connected nearby room (i.e. basement) if the tank is full or overflowing. One way to do this is to
ensure that the line gradient from the house to the tank is steep enough. We recommend
installing a sealing collar in the conduit.
2.4.4 Install the pipes so that frost protection is ensured. The relevant factors must be determined
based on the regional weather conditions, and, if necessary, in coordination with local authorities.
