there is a guarantee that waste water which is unsuitable for treatment by a central waste water treatment plant may be disposed of in an appropriate manner (Art. 12 para. 2).
1 In the case of small buildings and installations in an area served by public sewers but which for overriding reasons cannot be immediately connected to such sewers, a building permit may be granted where it is possible to provide the connection in the short term and that in the meantime the waste water may be disposed of in another satisfactory manner. Before the authority grants a building permit in such circumstances, it shall consult with the cantonal water protection agency.
2 The Federal Council may define the exceptions in greater detail.
1 The cantons shall divide their territory into water protection areas according to the risks of pollution to which surface and underground waters are subject. The Federal Council shall enact the required regulations.

1 The cantons shall ensure that waters are rehabilitated. In doing so, they take account of the benefits to nature and the landscape as well as the economic consequences of the rehabilitation.
2 They shall plan the rehabilitation measures and specify the time schedule therefor. They shall ensure that these plans are taken into account in the structure and land use planning.
