Government regulations require developments over 80 rooms
to have their own sewage treatment system. However, developers
bypass this requirement by dividing projects into smaller entities.
This has led Thai authorities to implement additional legislation for
resorts or hotels with less than 40 rooms (ONEP, 2006; Wong,
1998). Although legislation is present, government has been slow
in responding to the rapid development, with little or no enforcement
of regulations (Wong, 1998), so the impact of unplanned
tourism development continues.
