Can staff legally work without toilets during a water outage?

Employers must provide adequate sanitary facilities for employees. A water outage does not remove that duty — you need to substitute with temporary facilities such as self-contained portable toilets. Confirm the exact requirement for your headcount with your health and safety officer.

How quickly can portable toilets be delivered during an outage?

Availability depends on how widespread the outage is. Businesses with a standing arrangement and agreed rates are always served faster than first-time callers, which is why pre-arranging cover is the main recommendation in this checklist.

How much water storage does a small business need?

As a planning starting point, around 2,000 litres covers up to 20 staff for roughly 48 hours of normal use. Add capacity if you have canteen, wash-bay or production water use.

Water Outage Plan For Gauteng Businesses (Checklist)

What to have in place before the next shutdown so staff can stay on site legally and comfortably.

A planned municipal shutdown is announced days ahead. An unplanned one arrives at 06:30 on a Monday. Both have the same effect on your business: no ablutions means staff cannot legally or reasonably remain on site. This checklist is what we see working for Gauteng offices, warehouses, schools and sites.

Step 1: Know your minimum ablution requirement

South African occupational health and safety regulations require employers to provide adequate, accessible sanitary facilities for employees, with separate provision for men and women where applicable. When mains water stops, that obligation does not pause — you have to substitute, not suspend. Confirm your specific numbers with your health and safety officer, since requirements scale with headcount and site type.

Step 2: Size your storage

Staff on site	Minimum storage for 48 hours	Typical setup
Up to 20	2,000 L	1 JoJo tank + pressure pump
20–60	5,000 L	2 tanks + pump, plus 2 portable units
60–150	10,000 L	Tank bank + 4–6 portable units
150+	Bulk delivery contract	Ablution trailer + servicing schedule

These are planning starting points, not regulatory figures — actual demand depends on shift patterns, whether you have canteen or wash-bay use, and how long your typical outage lasts.

Step 3: Pre-arrange sanitation cover

Have a supplier on standby with agreed rates, not a number you find on the day.
Confirm the delivery window your supplier can realistically hold during a widespread outage.
Choose self-contained units with their own fresh-water tank — a mains-fed unit is useless in an outage.
Agree a servicing frequency up front: daily for high-traffic sites, every second day for smaller teams.
Confirm where units will be placed and that a service vehicle can reach them.

Step 4: Communicate before staff arrive

Send a WhatsApp or SMS the night before a planned shutdown.
State clearly whether ablutions are available and where.
Give a decision rule for unplanned outages — who calls it, and by when.
Post signage at the entrance directing staff and visitors to temporary units.

Step 5: Review after every outage

Log how long it lasted, what ran out first, and what you would order sooner. Two or three of these logs will tell you exactly what your standing arrangement should be.
