Building and Construction Sites

This information is reproduced from the Portable Toilets Code of Practice available from the Hire and Rental industry Association. Instant Toilets & Showers can advise you on situations which may affect the number of toilets which should be provided for your work site.

For commercial construction/work sites we recommend weekly servicing.
NOTE: Unisex toilets must be provided where there is any likelihood of female workers.
These
 must include the provision for the disposal of sanitary items.

Legislation in Western Australia requires toilets to be serviced on a maximum of a fortnightly schedule.
