Onsite Detention Tanks

If you’re looking to manage rainwater runoff during heavy rainfall and maximize water capacity, an on-site detention tank (OSD) might be essential depending on your location. These tanks not only help conserve water but also support urban development by reducing the risk of local flooding and protecting the community.

An On-Site Detention (OSD) Tank Essential for Stormwater Management

Ideal For:

  • Domestic Properties
  • Commercial Projects
  • Caravan & Tourist Parks 
  • Eco Villages 
  • Accomodation Complexes
  • Resorts 
  • Eco-tourism and remote locations 
  • Service Centres & Facilities
  • Mining
  • Bed & Breakfast Accomodation (B&B)
Flood Mitigation

OSD tanks reduce the risk of local flooding by temporarily storing stormwater and releasing it at a controlled rate into the drainage system.

Compliance with Regulations

Many local councils mandate OSD installation for new developments or renovations to ensure sustainable urban water management practices.

Infrastructure Protection

By managing stormwater runoff, OSD tanks prevent council drainage systems from being overwhelmed, especially during heavy rainfall events.

Customisable Design

OSD tanks can be tailored to meet specific site requirements, including size, integration with rainwater tanks, and adherence to council-approved specifications.

The Eco-Septic "OSD Tanks"

Looking to store rainwater runoff during times of heavy rainfall and maximise your water capacity. Depending on where you are located you may require the installation of an on-site detention tank/s.

The purpose of the installing the Eco-Septic tank is not only to conserve water, its also supports urban development and protects the community, by bringing about a reduction in the chance of flooding in the local area.

What is an On-Site Detention Tank (OSD)?

An OSD, also known as an on-site stormwater detention tank, temporarily stores stormwater runoff and gradually discharges it into the council stormwater system or drainage areas. Unlike retention or rainwater tanks, OSDs are not meant for water reuse. They remain empty except during rainfall and for a short time afterward, ensuring proper flow control without retaining water for domestic purposes.

Managing Rainwater with On-Site Detention Tanks (OSDs)

If you’re looking to manage rainwater runoff during heavy rainfall and maximize water capacity, an on-site detention tank (OSD) might be essential depending on your location. These tanks not only help conserve water but also support urban development by reducing the risk of local flooding and protecting the community.

Operation of OSDs

OSDs temporarily capture and store stormwater runoff, then slowly release it through a controlled outlet into the council drainage system. This process reduces peak water flow during heavy rains, protecting local infrastructure and preventing flooding.

For buildings with large roof areas, OSDs manage substantial volumes of water, ensuring controlled release to avoid overwhelming the local drainage system.

Why are On-Site Detention Tanks Required?

Local councils mandate the installation of OSDs to prevent drainage infrastructure from being overwhelmed by stormwater runoff. Urban developments, such as new roofs and hard surfaces, increase the volume and speed of runoff while reducing its ability to soak into the ground. These conditions necessitate proactive measures to mitigate downstream flooding risks.

Councils have implemented policies to address these challenges, ensuring sustainable stormwater management for the future.

When are OSDs Required?

OSDs are typically required in areas prone to flooding or with insufficient drainage infrastructure. Councils may mandate OSD installation for properties undergoing new construction or renovations that increase impervious surfaces, including townhouses, villas, commercial buildings, schools, and sporting facilities. Solo residential homes or properties below a certain size may be exempt, but it’s vital to confirm requirements with your local council.

Cost of On-Site Detention Tanks

The cost of an OSD varies depending on factors such as size, accessories, finish, and structural strength. Rain Cycle offers customized pricing to suit individual project needs and budgets. Contact our team for tailored advice and a detailed quote.

 

How it works

5 Easy steps

Installing an On-Site Detention (OSD) tank doesn’t have to be a complicated process. These systems play a critical role in managing stormwater runoff, reducing flood risks, and protecting local infrastructure. 

By following these five easy steps, you can ensure a smooth installation process that meets all council requirements while providing long-term benefits for your property and the surrounding community.

Consult Your Local Council

Check the specific requirements and regulations for OSD tanks in your area, including permissible discharge rates and storage volume needs.

Engage a Qualified Engineer

Work with a licensed engineer to design an OSD system that meets council specifications, including size, flow control, and integration with other drainage systems if needed.

Obtain Council Approval

Submit your design plans to the council for approval to ensure compliance with all regulatory standards.

Install the OSD Tank

Hire professionals, such as Rain Cycle, to install the tank according to approved plans, ensuring all components like orifice plates, inlets, and overflows are in the correct position.

Verify and Maintain the System

After installation, verify that the system operates as intended and schedule regular maintenance to keep it functioning efficiently during heavy rainfall.
