Installation of Municipal Backup System

Pre-installation:

Choose a tank

How to calculate what size tank would be sufficient for Municipal Back Up:

People 1 2 3 4 5
Litres/ day 150 300 450 600 750

Size of tank = litres p/day X total days back up required i.e. 4 people (600L) X 3 days = 1800L

Tank placement

Should be placed where municipal supply can be intercepted, before entering the house.

Base / foundation

Tanks must be installed on a sound, level and smooth surface. Level paving will suffice, or a properly designed tank stand, alternatively a concrete plinth needs to be built. Ideally the plinth should be covered by a concrete topping at least 85mm thick.

It is recommended that the foundation should be at least 100mm wider than diameter of tank.
