Storm water Detention Tanks now required in Auckland

January 18th, 2017

Ever wondered why Auckland has such massive flooding problems and what you can do as a home owner to prevent this happening to you? Introducing New Zealand made Storm water Detention Tanks, designed particularly for Aucklanders’ and our beautiful Auckland weather. Solve your problems once and for all today

Updated 2017 It is no secret that we get a lot of rain in Auckland and with the  continued population growth, the number of houses being built is also on the increase. This means new tracts of land are being developed and in some cases the land mass is high in clay composite which makes drainage an issue for the houses being built on the sections. Couple that with getting our famous Auckland “downpours” and you have big problems. The intense rainfall can overwhelm our aging storm water system and flooding can occur making the Insurance companies and home owners upset.

This was why the Auckland Council put in regulations around storm water Detention Tank design and storm water detention systems some years ago, making the installation of storm water Detention Tanks “required for consent purposes”. The idea was to give some relief to the already stressed storm water system in Auckland.

On the  North Shore of Auckland, it is compulsory to install an underground Detention Tank, as a lot of the subdivision areas are based on clay. With the advent of the Auckland Super City Council, parts of Auckland City and what was Manukau City have now had legislation passed also making the installation of underground Detention Tanks compulsory in parts of the region. It is wise to check with your council before commencing the project to see where you stand and if you need a storm water Detention Tank then contact us to discuss your requirements. APD custom build tanks to suit all types of situations.

If you have any concerns, you are welcome to speak with our underground Detention Tank experts and they can guide you on who to contact at the council. It is interesting to note that the Rodney District Council requires Detention Tanks for storm water in parts of their borough also.  Storm water Detention Tanks have also been seen in Papakura and Pukekohe, as councils step up the projects of reducing storm water and waste water flooding . It would seem we get a lot of rain in the Auckland region! The councils are being lobbied by the insurance companies who continually see the increased damage caused by storm water flooding when storm water Detention Tanks are not installed. Insurance costs spiral upwards and home owners with no underground storm water tanks get equally frustrated by rising insurance costs and insurance excesses increasing each flood.

The heavy flooding caused by storm water generally gets into household basements and causes massive problems for home owners with damage to furniture, flooring. wall panels,  and electrical goods.

What are storm water Detention Tanks and how do they work?

Storm water Detention Tanks are tanks that temporarily store rainwater collected from your roof and other hard surfaces on your property and then release the water at a much slower rate.

Intense rainfall events and storms can dump large amounts of water on your property in a short period of time, so Detention Tanks are often referred to as storm water Detention Tanks because they catch and hold water from these intense events in the short term and release the water over a longer period.  The controlled release of the water is through a small diameter hole, called an orifice. Without a Detention Tank the water rushes into the local drainage system in an uncontrolled manner. Temporarily storing or “detaining” the water and then slowly releasing it over a period of time, reduces short term peak outflows from your property and minimises the impact of the water on the local environment, reducing the risk of local flooding and erosion in local streams.

Storm water Detention Tanks, are made by APD (Advanced Plastics and Design) custom built to each project. We can normally produce these tanks in one week or less and they come ready for installation in your building site. The plastic is very strong and robust making the tank a perfect solution to minimise flooding. At APD we have been custom building plastic tanks and other items for many years. If you need it made in plastic, then we are the company to make it for you.

You will notice in the photo on our plastic Detention Tank page that these tanks come in a range of sizes.

We also do Chemical Tanks, Water Tanks and anything else made of plastic.  You can see some of the projects on this page.
