What are the arrangements for rainwater drainage?
There are two options. In the case of temporary buildings, we generally fit drainpipes down the outside of the building. The water from each unit is either collected directly by the drainpipes or runs into a gutter connected to the drainpipes. In more permanent buildings, rainwater is collected at one or more central points, from where drains off into the main sewers via internal pipes. The exterior of the building is then free of unsightly drainpipes.
