The municipality allocated the only piece of communal land on
the island for the treatment system and a local landowner provided
land for the pumping station. It was not legally possible to force
households to connect to public wastewater collection systems.
Consequently, it was decided to provide household connections
as an integral part of the wastewater management system. This
meant that the construction contract included service pipes and
actual connection taps for households that needed and wanted to
connect, and the installation of septic tanks and oil and grease traps
for households, restaurants, and hotels that were willing to have
them installed.
