A resource consent for discharging stormwater into the ground where there is no connection to the local stormwater system. A consent to discharge stormwater is usually only necessary for industrial and trade premises. This means that in most cases you do not need consent to discharge stormwater from domestic dwellings. However, if you wish to discharge stormwater to land or water from a non-industrial or trade premise other than via a connection to a city or district council’s stormwater network, you will need a resource consent if the discharge will not comply with all of the conditions in Rule 42 of the RRMP
Before you apply you will need to read
Please note that different rules apply to consents within the coastal environment governed by the Hawke’s Bay Regional Coastal Environment Plan.
Technical Information - Consents for Stormwater Discharge
The following technical information gives details on consent requirements -
A consent to discharge stormwater is necessary for industrial and trade premises. This means you do not generally need consent to discharge stormwater from single domestic dwellings, but may need consent for residential developments. You should also check with your local Council for any stormwater management requirements for your site, and if you intend to connect to a local Council reticulated stormwater network.
If resource consent is required, it is a Controlled Activity under Rule 43 of the RRMP. The matters for control are:
- Location of the point of diversion and discharge including its catchment area.
- Volume, rate, timing and duration of the discharge, in relation to a specified design rainfall event (at least 1 in x year).
- Effects of the activity on downstream flooding.
- Contingency measures in the event of pipe capacity exceedance.
- Actual or likely adverse effects on fisheries, wildlife, habitat or amenity values of any surface water body.
- Actual or likely adverse effect on the potability of any groundwater.
- Duration of consent.
- A compliance monitoring programme.
- A bond.
- Administrative charges.
Industrial sites are potentially significant sources of contamination to receiving systems/environments. These receiving systems are discussed in some detail in the ‘Waterway Design Guide’
- Open coasts
This guideline provides information on:
- Source control and site housekeeping
- Industries, contaminants of concern and appropriate treatment practices
- Stormwater treatment for contamination reduction.
Stormwater management and treatment design is complex and will require an engineer for a design solution. Below are engineers within the Hawke’s Bay region that have experience designing stormwater management systems.

Rules for activities in the coastal strip governed by the Coastal Environment Plan vary from the RRMP -
This application needs to be signed by the applicant, however, it is generally completed by the stormwater system designer.

A resource consent is a legal document. Keep it in a safe place and check it regularly to be sure you are fully aware of conditions.
