How does detention tank work?
Detention tanks work by temporarily storing the rainwater runoff during a rainfall event and then slowly releasing the water through a controlled small diameter orifice into the public storm water system. Giving the ground enough time to “soak” excess water will prevent any surface or ground related flooding.
How do water retention tanks 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. These can be located either above or below ground.
How much does a detention tank cost?
A 3000 litre Thin Tank costs $2200 excluding the costs of fitting it, and plumbing it in. Families in Auckland pay a single bill for water and wastewater to Watercare.
Is it better to have a larger well pressure tank?
That being said, bigger is better for your pressure tank. What kills well-pumps is starting, it takes the most abuse from starting, so running is the least work. So to have a larger tank means fewer starts and longer run times, and it also means more available volume and stable pressure in the water plumbing.
When to use a water storage tank or a retention tank?
Water Storage Tanks/ Retention Tanks Water storage tanks and water retention tanks are different normally. So when you need “contact time” (time for the water to stay in a tank with chlorine or other chemicals to do their job), retention tanks are the way to go. But if you are trying to store water for a weak producing well or other purpose.
How big of a water tank do I Need?
Tank size is not necessarily based on collecting total roof run-off. For example, from Table B1 the maximum water that can be collected from a roof area of 200 m 2, with an annual rainfall of 1000 mm, is about 156 kL. If the water demand is less than this, some overflow may occur while demand is still met.
How big does a detention tank need to be?
In Auckland a rule of thumb based on several conditions including “storm of the 100 years” would be to allow for 100 liters per 1 SQM of roof surface area. Depending on detention requirment and specifications, the outlet orifice could be anywhere between 10mm-40mm.
