ON-SITE STORMWATER DETENTION
Urbanscapes designs and constructs block-built on-site stormwater detention (OSD) tanks for civil, commercial, industrial and residential subdivision projects. We work with developers, civil contractors and project teams to deliver block construction OSD tanks in accordance with project requirements.
Our focus is on practical construction solutions that integrate with surrounding civil works and project requirements.
BLOCK-BUILT OSD TANKS
On-site stormwater detention (OSD) tanks are designed to temporarily store stormwater runoff during rainfall events and release it at a controlled rate.
Urbanscapes specialises in the construction of block-built OSD tanks for developments where stormwater detention is required as part of the approved drainage design.
We design and construct block construction OSD tanks, coordinating with project engineers and civil contractors to ensure construction aligns with the project's engineering documentation, site conditions and construction programme.
Our block construction OSD tanks provide a practical solution for developments requiring stormwater detention infrastructure, with the construction scope established to suit each project.
WHY STORMWATER DETENTION MATTERS
As land is developed for buildings, roads, car parks and other hard surfaces, rainfall produces greater surface runoff and less water is absorbed into the ground.
On-site stormwater detention systems temporarily store runoff and regulate its discharge into the downstream drainage network.
OSD tanks may form part of a development's stormwater management requirements under council or other approval conditions.
The required detention capacity, tank configuration and outlet arrangements are determined by the project's stormwater engineering design.
UNDERGROUND OSD TANK CONSTRUCTION
Urbanscapes Constructions delivers underground On-Site Detention (OSD) tanks using reinforced concrete block construction. Each stage of the construction process is coordinated to suit the approved stormwater design, structural requirements and site conditions.
From the initial blockwork through to reinforcement, core filling, waterproofing and final access covers, our team provides design and construction services for underground OSD tanks across residential subdivisions, commercial developments and civil infrastructure projects.
STAGE 01
Concrete block construction with multiple chambers
Underground OSD tanks are constructed on site using concrete blockwork to form the external walls and internal chambers. The tank layout is established in accordance with the approved stormwater engineering documentation, with consideration given to the required storage capacity, inlet and outlet locations, internal flow paths and site constraints.
STAGE 02
Completed block walls and internal slab
The internal block walls and chambers form the structure of the underground detention tank, providing the configuration required for stormwater storage and controlled discharge. Internal partitions, openings and connections are coordinated with the approved design to ensure the tank functions as intended within the development's stormwater management system.
STAGE 03
Steel reinforcement positioned within the blockwork
Steel reinforcement is installed within the concrete block walls in accordance with the structural engineering specifications. Reinforcement placement, including vertical bars and horizontal steel where required, is coordinated with the blockwork construction to prepare the walls for core filling and achieve the specified structural performance.
STAGE 04
Reinforced blockwork core-filled for structural strength
Once reinforcement is positioned and the blockwork is ready, the cores are filled with concrete or grout as specified in the structural design. Core filling creates the reinforced wall system required to withstand the loads and conditions identified for the underground OSD tank.
STAGE 05
Tank walls sealed with a specified waterproofing system
Waterproofing is applied to the tank walls and other designated surfaces following completion and preparation of the structural works. The selected waterproofing system and application method are determined by the project specifications and site requirements to help protect the tank structure against water ingress.
STAGE 06
Access openings fitted with suitable covers
Access covers are installed over designated inspection and maintenance openings to provide access to the underground tank for ongoing servicing and cleaning. Cover selection and installation are coordinated with the surrounding surface, including traffic-rated requirements where the tank is located beneath driveways, roads or other trafficked areas.
STAGE 07
Finished underground tank integrated with the surrounding development
The completed OSD tank is integrated with the development's stormwater infrastructure and surrounding surface works. Final construction, access provisions and associated connections are completed in accordance with the approved project documentation, with inspections and handover undertaken as required by the project.
CIVIL AND COMMERCIAL DEVELOPMENTS

APPLICATIONS
Industrial facilities, warehouses, logistics centres and commercial buildings can generate substantial stormwater runoff from roofs, hardstands and paved areas.
Block-built OSD tanks provide temporary detention storage where required by the site's stormwater design.
Residential subdivisions may require stormwater detention infrastructure to manage runoff from new roads, homes, driveways and other developed surfaces.
Urbanscapes works with civil contractors and development teams to design and construct block construction OSD tanks for subdivision projects.
Civil construction projects can require stormwater detention as part of broader drainage and infrastructure works.
We coordinate block OSD tank construction with surrounding civil works in accordance with project requirements.
Data centres and large facilities can have extensive roof areas, access roads and service yards that contribute to stormwater runoff.
Block-constructed OSD tanks can form part of the site's engineered stormwater detention infrastructure.
HOW IT WORKS
Rainfall runoff from designated roofs, paved surfaces and other catchment areas enters the site's stormwater drainage system.
The OSD tank provides detention storage during rainfall events.
The tank's required storage capacity and configuration are determined by the approved stormwater design.
An engineered outlet regulates the release of stored stormwater into the downstream drainage network.
The outlet configuration and discharge requirements are established by the project's stormwater engineering documentation.
