What is Storm Tank?

The Rain Tank is a sub-surface rainwater storage tank with highly permeable surfaces made up from manufactured modular components. It is used “at-source” allowing the option for infiltration, detention, or retention.

How does a stormwater tank work?

When it rains, the tank collects stormwater and releases it at a rate specified by design into the council stormwater system. This helps to prevent flooding on your property, reduces the impact of heavy rain on the council system and, consequently, protects our waterways and coastal environments from erosion.

What is the purpose of stormwater?

By reducing the speed and amount of water running to the streams, stormwater management helps to prevent excessive erosion. If stormwater is not managed, it can cause excessive erosion that may prevent the stream from fulfilling its normal function of conveying water and sediment.

What is a storm detention tank?

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.

How close can water tanks be to boundary?

If your tank is over 1m in height AND will be placed near a boundary line or water course, will obstruct a window or outdoor amenity area, or if you are in a Special Character or Historic Heritage area, you will most likely need a resource consent.

How do you manage stormwater flow?

Employ sediment traps and divert ‘clean’ stormwater around the disturbed site (see Sediment control). Minimise the area of impervious surfaces such as paved areas, roofs and concrete driveways. Grade impervious surfaces, such as driveways, during construction to drain to vegetated areas.

How does detention tank work?

Detention tank: Detention tanks work by temporarily storing stormwater runoff during a rainfall event and then slowly releases the water into the public stormwater system. Retention tank: A retention tank is used to permanently hold rainwater, which can then be re- used for hose taps, toilet use and laundry purposes.

What is the purpose of detention tank?

A detention tank in the sewer network is used to even out peak flows in the system. This helps to avoid overflow into the recipient, protecting downstream areas. It also helps to prevent hydraulic overload of downstream sewers and wastewater treatment plants.

Is it worth having a water tank?

Are rainwater tanks worth it? Well consider that a maintained rainwater tank can last up to 30 years and over that time can provide significant savings on your water bills, help our water shortage crisis and provide you with fresh water during times of water restrictions and droughts.

What are the benefits of rainwater tanks?

Using rainwater can reduce water bills, provide an alternative supply during water restrictions, and help maintain a green, healthy garden. Depending on tank size and climate, mains water use can be reduced by up to 100%. This in turn can help: reduce the need for new dams or desalination plants.

Why do you need a stormwater detention tank?

The emptying of stormwater by detention tanks keeps space available in the tank for more water to be detained in consecutive downpours. The slow release of water into drains from stormwater detention tanks helps to assist your local area with more manageable loads of water runoff, helping to prevent flooding.

How big does a stormwater tank need to be?

This tank can be up to 2.5m deep, and can easily be accessed and inspected by a professional via an inspection well. Stormwater Crates work in a similar way and are perfect for groundwater infiltration.

How does a stormwater attenuation tank work?

Where the previous two methods of storm attenuation simply caught water from their surrounding area, a separate tank has the ability to capture water from a very wide area using connected pipes, and collect it all together in one huge tank for distribution. How Do Soakaway Crates Work? How Many Soakaway Crates Do I Need?

What makes up an underground storage tank system?

An underground storage tank (UST) system is a tank (or a combination of tanks) and connected underground piping having at least 10 percent of their combined volume underground. The tank system includes the tank, underground connected piping, underground ancillary equipment, and any containment system.
