Retention tanks

Retention tanks are used to temporarily store large amounts of rainwater and discharge into an existing sewer network or natural environment. 

Retention tanks are made of spiral corrugated pipes HelCor.

Stormwater tanks are a key component of stormwater management systems. These reservoirs play a crucial role in minimizing the risks of flooding, reducing the load on the sewage network,mitigating the effects of extended dry periods and promoting a more sustainable use of rainwater.

The stormwater management of the future

One of the most important areas of storm water management is the treatment of surface water from oil and sand particles. High-efficiency treatment plants protect the environment from dangerous pollution.

Our retention tanks are made from light, strong and reliable construction.

ViaCon can offer the retention tanks of various designs that can be adapted to different areas.


Application areas:

Parking lots
Logistic centers

Thanks to our own production can we customise our products

By taking care of the water in the right way, it can be used again

Rainwater tanks for a sustainable future

Rainwater tanks have become a central component in sustainable water management and environmentally friendly construction technology. These tanks play a crucial role in collecting, separating, storing and using rainwater to minimize waste, protect the environment and contribute to a more sustainable future.

A rainwater tank is a container specially designed to collect and store precipitation, especially rainwater. This technology has grown in popularity as a reaction to increased awareness of water resources and environmental responsibility.

Rainwater tanks can be made of different materials, including plastic, concrete, steel or fiberglass, and are available in different sizes to suit different areas of use.

Frequently asked questions about different water tanks

What is a stormwater reservoir?

A rainwater reservoir is a device used to temporarily store and manage large amounts of rainwater. It is designed to prevent flooding and erosion by slowing the runoff of stormwater and releasing it in a controlled manner.

What is the difference between a stormwater tank and a stormwater reservoir?

The terms are often used synonymously, but a stormwater tank usually refers to a specific structure for storing water, such as a pipe reservoir, while a stormwater reservoir can be a broader term that includes various solutions for managing stormwater.

How does a stormwater tank work?

A stormwater reservoir works by collecting rainwater from an area and storing it temporarily. When the level in the reservoir reaches a certain limit, the water is released either into an existing sewage network, natural environment or used for irrigation. The water can also be used to reduce costs and increase sustainability in the built environment, such as for toilets or as process water for manufacturing.

How can stormwater reservoirs contribute to a better environment?

Stormwater tanks help reduce the risk of pollution in waterways by removing pollutants from rainwater. They can also be used to also promote the reuse of water, which reduces the need to take from natural resources.

What is the difference between stormwater pipes and stormwater tanks?

Stormwater pipes are used to transport stormwater from one location to another, while stormwater tanks are used to temporarily store and manage stormwater before it is discharged or used. If the volume in the stormwater pipes is increased at the same time as the flow is limited, a storage/storage function can also be achieved in stormwater pipes.

What is an irrigation tank and how is it different from a rainwater tank?

An irrigation tank is a special type of tank used to store water for irrigation of green areas, gardens and crops. The difference lies in the use, where an irrigation tank is primarily used for irrigation, while a stormwater tank handles stormwater from rain and runoff.

Can a rainwater tank also be used as an irrigation tank?

Yes, in some cases stormwater tanks can also be used for irrigation if the water has been purified and is suitable for the purpose. This can help save water resources.

What are the most common uses for irrigation tanks?

Irrigation tanks are mainly used for green areas, agriculture, gardens, golf courses and crops. They are a critical component in ensuring access to water for cultivation and landscape irrigation.

How can I ensure that the water in an irrigation tank is suitable for irrigation?

The water in an irrigation tank should undergo appropriate treatment and filtration to ensure that it is free from impurities and suitable for irrigation. This may include particle separation and chemical treatment if necessary.

What is a rainwater tank?

A rainwater tank is a container used to collect and store rainwater from the roof of buildings. The stored water can then be used for various purposes, including irrigation and other non-potable purposes.

What is the purpose of rainwater recycling?

The purpose of rainwater recycling is to use rainwater as an alternative source of water for non-drinking purposes, such as irrigation, toilet flushing and laundry. This reduces the pressure on the drinking water supply and helps conserve water resources.

How does a delay magazine work and what is its purpose?

A delay reservoir is a device used to temporarily store stormwater and gradually release it into the sewer network or natural waterways. The aim is to reduce the risk of flooding by delaying the flow of rainwater into the drainage system.

What are the benefits of using rainwater recycling systems?

The benefits of using rainwater recycling systems include reduced use of potable water for non-potable purposes, cost savings and reduced strain on the water supply system.

Can I use a stormwater tank for rainwater recycling?

Yes, in some cases a stormwater tank can be used to collect rainwater for recycling, provided the water is cleaned and treated as needed.
