# A latrine which consists of two chambers or vaults used alternately, with one collecting faeces while the other decomposes the wastes (WHO and IRC 2003).

==Explanation==
The double-vault compost latrine consists of two watertight vaults or chambers to collect
the faeces. Urine is collected separately, because the contents of the vault should be kept
relatively dry. After each use the faeces are covered with organic material to reduce smells
and soak up excessive moisture. When the first vault is three-quarters full, it is completely
filled with earth and sealed, and the contents allowed to decompose anaerobically. The
second vault is then used and when it is three-quarters full, the first vault can be emptied,
even by hand, and the contents used as fertilizer (WHO and IRC 2003).

==Example==
“Latrine systems may be built with either one or two pits or vaults, depending on
affordability, housing density and socio-cultural habits. In the case of two pit/vault systems,
only one is in active use at any one time with the other being used to allow pathogen
inactivation and decomposition of the excreted material.” (WHO and IRC 2003)
