Stormwater Detention Tanks | Drainwell

Stormwater Detention Tanks are used to control stormwater runoff. Stormwater runoff is a nuisance on commercial as well as residential sites. Excess runoff is a hazard especially during large rainfall events.

Who makes Drainwell Underground Tanks ?

Drainwell Tanks are made by Novaplas Group. The tanks are made from 100% recycled materials.

Drainwell Drainage Cells are easy to install and also provide a solution to many constraints on building sites.

Drainwell tanks have many uses.

These uses include:

  • Stormwater Detention Tanks
  • Rainwater Harvesting Tanks
  • Infiltration Tanks
  • Rain Gardens
  • Roadside Swales

The Drainwell system can be installed below vehicle areas, due to its high crush strength. The panels that make up the Drainwell module have moulded rings. These rings are cut around with a hand held jigsaw so that pipes can be fitted.

Drainwell tanks are the solution to many WSUD issues.

What is Stormwater Detention ?

Stormwater detention is the process of holding stormwater run-off from your site. The collection and slow release of stormwater is called stormwater detention. As a result, all development areas can be safely controlled.

Certain councils have specific stormwater codes. These requirements can vary for different land developments.

Drainwell Cells are used to detain excess stormwater. The water is stored and then discharged into either stormwater pipes or channel systems. Many new buildings require Onsite Detention Tanks (OSD Tanks).

Why is stormwater detention necessary?

Stormwater Detention is necessary due to an increase in the number of dwellings within Council areas. Increased housing density has resulted in more hard surfaces. However, the water from these surfaces needs to be discharged into the Council drainage system. As a result, stormwater detention tanks are a Council requirement in many development approval processes.

Stormwater Retention Tanks

Drainwell Tanks are also used to retain stormwater for reuse. The runoff comes from car parking areas, golf courses, racecourses, as well as sports fields.

Therefore, this water can be used for irrigation. Captured rain water is much healthier for your garden than treated water from the mains.

Infiltration Tanks

Drainwell cells are also used for absorption tanks, since water can permeate back into the natural water table.

KEY DRAINWELL BENEFITS:

  • Cells can be installed below car parking areas because they are trafficable.
  • The tank is underground, as a result, the surface above the tank can be used for car parking or landscaping.
  • Transport and installation of Drainwell is easy when compared to concrete and gravel systems.
  • Drainwell cells have a 95% void area. Therefore, a greater volume can be achieved in a smaller area.
  • The cells are made from a 100% recycled polypropylene.
  • Drainwell Cells are used specifically for underground tanks.
