are permitted activities subject to the following conditions:
- Total pipe diameter shall not exceed 300 millimetres or have a cross sectional area exceeding 0.071 square metres.
- The intake or discharge structure shall not extend more than five metres, horizontally from the river or lake bank, or for more than 10 percent of the river bed width, whichever is the lesser.
- The structure shall be kept free of debris.
- The construction works shall comply with the suspended solids discharge standards as set out in Section 4.2.21.
- The structure shall be maintained in a structurally sound condition at all times.
- Where the water body exceeds 10 metres wide the presence of the structure shall be clearly indicated to river users by the use of signs.
- All equipment and surplus construction materials shall be removed from the river or lake bed and the floodplain on the completion of that activity.
- No contaminants (including, but not limited to, oil, hydraulic fluids, petrol, diesel, other fuels, paint or solvents, but excluding sediment) shall be discharged to water from the activity.
- The activity shall not disturb any archaeological site or waahi tapu as identified at the date of notification of this Plan, in any district plan, in the NZ Archaeological Association’s Site Recording Scheme, or by the Historic Places Trust except where Historic laces Trust approval has been obtained.
- In the event of any waahi tapu that is not subject to condition i) being identified by the Waikato Regional Council to the person undertaking the use, erection, reconstruction, placement, extension or alteration, the activity shall cease insofar as it may affect the waahi tapu. The activity shall not be recommenced without the approval of the Waikato Regional Council.
- The structure shall provide for the safe passage of fish both upstream and downstream.
- Any erosion occurring as a result of the structures shall be remedied as soon as practicable.
- This rule shall not apply to activities located in, on, under or over the bed of a river or lake that is a Significant Geothermal Feature.
- The structure shall be consistent with the provisions specified in the Water Management Classes in Section 3.2.4. of this Plan.
- Refer to Chapters 3.3 and 3.5 of this Plan for rules concerning the take and discharge of water.
- The use, erection, reconstruction, placement, alteration or extension of a discharge or intake structure in or on the bed of a river or lake that does not comply with Rule 18.104.22.168 is a discretionary activity in accordance with Rule 22.214.171.124.

- Where a structure or activity is to be located in, on, under or over the bed of a water body that is Significant Geothermal Feature, Rules 188.8.131.52 to 184.108.40.206 shall apply. Significant Geothermal Features are defined in the Glossary, and in Development and Limited Development Geothermal Systems, identified on maps in Section 7.10 of this Plan.
Explanation and Principal Reasons for Adopting Method 220.127.116.11
The purpose of Rule 18.104.22.168 is to allow discharge and intake structures as permitted activities up to a certain size as it is considered adverse effects of these structures will be minor. Above this size the use, erection, reconstruction, placement, alteration, and extension of discharge and intake structures will be discretionary activities because of the potential for adverse environmental effects.
The rules in Chapters 3.3 and 3.5 of this Plan require resource consents for water takes and discharges. These structures cannot therefore be used for the intended purposes until all necessary resource consents have been obtained.
