Stormwater

Our responsibilities

We maintain, modify and extend the stormwater disposal and land drainage systems to manage surface water run-off from all urbanised catchments and to minimise flood damage. Stormwater pipe systems are not designed to handle all storm situations. Storm events greater than those the system has been designed for will result in some surface flooding. These will ideally occur down predetermined overland flow paths.

We maintain, modify and extend the stormwater disposal and land drainage systems to manage surface water run-off from all urbanised catchments and to minimise flood damage.

Our stormwater infrastructure includes:

120km of pipes
32km of open drains
2,769 catch pits along roads
One dam and 19 ponds
Seven pumping stations – all servicing the Waihī Beach area.

Affordable Water Reform

The Government is considering how best to regulate and deliver the country’s three water services - drinking water, wastewater and stormwater. Find out more about what Council's position on this is.

Heavy rain and flooding

Floods are New Zealand’s number one hazard in terms of frequency, losses and declared civil defence emergencies.

When heavy rain is forecast for the Western Bay District, Council has a process in place for both the utilities and transportation departments to undertake pre-heavy weather inspections.

There are a number of locations in the stormwater network that Council’s maintenance staff check to ensure stormwater can flow uninterrupted.

Council encourages residents to take a proactive approach to clear debris from gutters and drains on their properties and to check roadside culverts on/near their driveways to ensure they are not blocked with debris.

The best thing residents can do to help is to let Council know before a heavy rain event if there are problems you’ve spotted that could contribute to flooding – such as blocked drains/culverts etc.

How ready are you?

Here are some tips:

Develop an emergency plan for your household or business
If you are a farmer or have a lifestyle block consider how and where you will relocate stock to higher ground
Prepare a getaway kit (in case you have to leave home in a hurry)
Where possible, move pets and animals inside or to a safe place
Make sure you have the appropriate household and contents insurance and keep those details handy
Stay informed. Severe weather events usually provide some time for warning and for you to take some preparedness actions
If you live in a flood prone area consider storing sandbags to protect your home should the need arise.

What to do if your place is flooding

Listen to your local radio stations as emergency management officials will be broadcasting the most appropriate advice for your community and situation
If you have a disability or need support, make contact with your support network
Put your household emergency plan into action and check your getaway kit
Be prepared to evacuate quickly if it becomes necessary
Where possible, move pets inside or to a safe place, and move stock to higher ground
Lift valuable household items and chemicals as high above the floor as possible
Fill bathtubs, sinks and storage containers with clean water in case water becomes contaminated
Turn off utilities if told to do so by authorities as it can help prevent damage to your home or community. Unplug small appliances to avoid damage from power surges
Do not attempt to drive or walk through floodwaters unless it is absolutely essential.

Stay up to date

If the weather is bad enough to be determined a Civil Defence risk the most up to date information and advice can be found by following Bay of Plenty Civil Defence on Facebook.

Bay of Plenty Regional Council has a Duty Flood Manager who:

Monitors weather forecasts and monitoring sites.
Determines level of response and mobilise teams as required.
Issues warning to landowners and public.
Works with field operations staff to monitor pump stations and other infrastructure during rainfall events.
Responds to queries and concerns from the public.
Liaises with District and City Councils, Civil Defence and Dam Operators.

Flood Maps

Flood modelling shows which areas might be flooded in an extreme rainfall event and to what depth they would get flooded.

Council’s natural hazard maps show a number of different types of flooding.

District Plan maps identify floodable areas in most urban areas as well as many rural areas.

For further information on flooding, and to view the above maps, these can be viewed on our natural hazards webpage.
