Using information from these three sites
http://helid.digicollection.org/en/d/Jh0210e/3.1.1.html (A guide to site sanitation)
http://www.thecanadianencyclopedia.com/en/article/solid-waste/
I estimated that the total combined litres of faeces & urine per person per day is
1.5 litres. The flush on the Vetus toilet has two settings eco-mode (1.2 Ltrs)
and a standard mode (2.2 Ltrs). Assuming that the toilet is used 7 times a day
(don’t ask) and one of those requires the standard flush, that is a total of 11 litres a day. This equates to a maximum of 30 person days between pump outs, or about a 12 days cruising for two people, if pumping out once 80% of capacity is reached.
