Concrete Pits and Grates from Sydney Water Tanks

SWT Concrete Pits and Grates produce a range of engineer designed concrete pits. All concrete products are manufactured at our own purpose-built precast concrete factory in Smeaton Grange.

SWT Concrete Pits and Grates are suitable for a wide range of applications including, stormwater, inspection, junction, electrical and sewer.

Although concrete storm water pits have no applicable Australian Standard, we hold product certification to both 'AS/NZS 1546.1 Small septic tank' and 'AS/NZS 1546.3 Aerated Wastewater Treatment Systems' Standards.

The concrete pits are manufactured under the same Quality Assurance procedures as the certified products. We are committed to providing the highest level of quality across all of our production processes.

Riser rings are available in a variety of sizes for all pits. SWT Concrete Pits and Grates will interpret your hydraulic drawings and precast inlets and outlets for detention control pits (DCP). The DCP will arrive onsite ready to connect.
