Checklist · 30 days · per person

Water & hygiene

Drinking, cooking and hygiene – calculated for 30 days. The federal minimum of 9 litres per person covers drinking and cooking for around three days; hygiene, for us, explicitly belongs with it. Our recommendation: 90 L of drinking water per person (3 L per day) plus quantified non-potable water – a combination of stored supply, treatment and collection at distribution points.

Water reserve

Water reserve
Item	Amount	Note
Immediate drinking water reserve	≥ 9 L	federal minimum: a six-pack per person – covers drinking and cooking for around 3 days; the entry point of this list, not its goal
Drinking water for 30 days	90 L per person	our recommendation, own calculation: 3 L per person and day for drinking and cooking × 30 days = 90 L – buy it in stages and rotate continuously
Non-potable water for hygiene & toilet	60–180 L	explicitly part of it: WHO guide value for basic hygiene 2–6 L per day, over 30 days 60–180 L – not fully storable, so a partial supply plus treatment plus a collection point
Canisters & water bags	≥ 20 L	if the supply is interrupted, the population collects water at distribution points themselves

Treatment

Treatment
Item	Amount	Note
Clean cloth or coffee filter	—	pre-clarify cloudy water before any disinfection – otherwise it works far less well
Water filter (mechanical)	—	absolute pore size of 1 µm or finer – retains parasites, but not viruses
Disinfection tablets / chlorine	—	the instructions on the pack are binding – Micropur Classic only preserves, Forte disinfects; when in doubt, boil
Stove for boiling	—	the safest treatment method – for stove and fuel see the «Heat & cooking» checklist
Rain & surface water as non-potable water only	—	must be treated before drinking and cooking – boiling does not help against chemical contamination either

Personal hygiene

Personal hygiene
Item	Amount	Note
Soap, shampoo, toothpaste	—	washing hands with soap also works against pathogens that hand sanitiser does not cover
Toilet paper	8–12 rolls	a value from experience, not an official quantity – estimate your own consumption
Wet wipes & hand sanitiser	—	at least 60 % alcohol – does not replace washing with soap when dirt is visible
Menstrual hygiene products	—	—
Nappies	—	if needed

Sanitation without water

Sanitation without water
Item	Amount	Note
Emergency toilet / bucket with bags	—	—
Litter / binding agent	—	—
Sturdy bin bags	roll	—
Household gloves	—	—

Cleaning

Cleaning
Item	Amount	Note
Dishwashing & cleaning agent	—	—
Disinfectant cleaner	—	—
Brush & cleaning agent for water canisters	—	clean containers before filling and label them with the filling date
