Preparation of this ICMP shall, where relevant to the particular catchment, take into account the entire area of Stage 1 of the Rotokauri Structure Plan, including the area identified in Figure 25.13.4a).
​Except that a separate ICMP is not required when all the information that it would otherwise include is incorporated into an approved Concept Development Consent for a Major Facility prepared under Rule 17.4 and the Concept Development Consent​ is accepted as satisfying the requirements of this rule.
​​Note
1.  The 3ha trigger in Rule 25.13.4.1(b)iii) relates to the footprint of the proposed development or subdivision.
2.  A full ICMP should be prepared at the Structure Plan stage in accordance with Chapter 3.3.​

​​
 25.13.4.2 Stormwater

a​) A stormwater reticulation and disposal system shall be provided that is adequate to safeguard people from injury or illnes​s and protect property from damage caused by surface water.​
b)​ Stormwater management measures shall be in place and operational upon the completion of subdivision and/or development to ensure that the rate of stormwater discharge offsite is at or below pre-development rates.  Stormwater management measures shall be implemented, as appropriate, in accordance with the following drainage hierarchy:  ​

i.Retention for reuse
​ii.Soakage techniques
​iii.Detention and gradual release to a watercourse
​iv.Detention and gradual release to stormwater reticulation.​ 

Note
1.  Acceptable means of compliance for the provision, design and construction of stormwater infrastructure, and the drainage hierarchy, are contained within the Hamilton City Infrastructure Technical Specifications.
2.  Bylaws may also impose additional controls or restrictions with regard to stormwater.
3.  See Rule 25.2.4 regarding earthworks.

25.13.4.3 Wastewater

​a) An adequate, reliable, safe and efficient wastewater service shall be provided.​
b)​ Where any subdivision or development results in additional allotments or buildings to be used for urban purposes, provision shall be made for a wastewater system as follows.​
i.​ The installation or upgrading of the wastewater network and/or wastewater pump stations  to serve all proposed allotments and/or buildings, and​
ii.​ Connection to the wastewater network from each proposed allotment or building.​
c)​ In the Future Urban Zone and Large Lot Residential Zone (Ruakura Structure Plan area only) where network utility services for wastewater treatment and disposal are not provided by Council, each sites shall adequately provide for its own on-site treatment and disposal of wastewater and provide evidence of a satisfactory wastewater system to Council:  no on-site wastewater treatment and disposal system shall be allowed that services more than one site and crosses any site boundary.​
​d)Rule 25.13.4.3c) shall not apply to any wastewater system servicing the 7ha development within Te Rapa North Industrial Zone Stage 1A, provided for under Rule 12.6.1 c)i), and connected to the wastewater infrastructure on Te Rapa Dairy Manufacturing Site.

Note
1. Discharge of trade waste to the Council network will require approval from Council in accordance with the Trade Waste Bylaw.
2. Wastewater treatment systems may require approvals from the Regional Council.
3. Acceptable means of compliance for the provision, design and construction of wastewater infrastructure is contained within the Hamilton City Infrastructure Technical Specifications.

25.13.4.4 Water

​​a) An adequate, reliable, safe and efficient supply of potable water shall be provided.​
b)​ Where any subdivision or development results in additional allotments or buildings to be used for urban purposes, provision shall be made for:​
i.​ Water metering infrastructure, and either​
ii.​ A connection from the public water supply reticulation to each proposed residential allotment or existing building, or​
iii.​ A public water supply reticulation system extending from the main trunk water supply system (or from an existing water supply reticulation if appropriate) to allow a service to be connected from the transport corridor frontage of each non-residential allotment.​
c)​ In the Future Urban Zone and Large Lot Residential Zone (Ruakura Structure Plan area only) where a water supply reticulation system is not provided, evidence of satisfactory water supply shall be provided as part of the consent application.​
d)​ A reticulation system shall be provided which is adequate for fire-fighting purposes and for estimated domestic and commercial consumption.​
e)​ Where a development results in high-use allocation from the water supply reticulation system, evidence of satisfactory water supply shall be provided.​

Note
1. There are limitations on the City’s municipal supply of potable water for industrial use other than human drinking and sanitation. Any industrial activity requiring more than 15m3 of water per day for purposes other than human drinking and sanitation is considered a high-use allocation and should consult Council’s Infrastructure Department early in the planning process.
2. Acceptable means of compliance for the provision, design and construction of water infrastructure is contained within the Hamilton City Infrastructure Technical Specifications.
3. Bylaws may also impose additional controls or restrictions with regard to water supply.

25.13.4.5 Water Efficiency Measures

​a) In addition to​​ Low Flow Fixtures, at least one water sensitive technique for stormwater shall be incorporated, connected to, achieved or maintained as part of any new development as identified below.​

Wh​ere required​ Water sensitive techniques​
​i. New reside​ntial units

ii. Other new buildings containing a kitchen, laundry or bathroom
  • Detention of stormwater to 80% of pre-development runoff by an appropriate means
  • Permeable surfaces protected to achieve at least 20% above the minimum standard of the zone
  • Rainwater tank for non-potable reuse system
  • Other equivalent feature
Note
1. An ICMP (relevant to the site) and the Hamilton City Infrastructure Technical Specifications can provide guidance on the above water sensitive techniques and other equivalent features.
2.  Council maintains a register of all full ICMPs and can advise of any relevant to a particular development proposal and site.

4. An ICMP may make recommendations identifying water sensitive techniques that are suitable (or unsuitable) for a particular catchment or specific Three Waters measures or targets that need to be achieved. In order for new development to comply with 25.13.4.5(a), the selection and implementation of water sensitive techniques must be consistent with any relevant recommendations.
5. To be effective rainwater tanks for new buildings should have a capacity of at least 5,000 litres or should be appropriately designed considering the specific site constraints.
6. Additional techniques are listed within the definition of "water-sensitive techniques" included in Section 1.1.2 of Volume 2 - Definitions Used in the District Plan.

vi.​ Creating a new building for non-residential activities (other than industrial activities or as provided for in vii. below) with a gross floor area greater than 300m2.​
​vii.​​Within the Major Facilities Zone:
​1.Creating a new building for non-residential activities (other than industrial activities) with a gross floor area greater than 3,000 m2; or
