What You Need to Know About Our Concrete Pits And Grates

At Sydney Water Tanks we use The Martins Group’s range of concrete pits that have been expertly designed. All products we use are manufactured in our very own purpose built precast concrete factory located in Smeaton Grange.

The pits and grates that we manufacture are suitable for many situations from sewer and electrical through to inspection, junction and stormwater. With riser rings available for all pits in all sizes.

Concrete pits and grates are designed to drain excess rain and groundwater from surfaces where water gathers, especially along footpaths, car parks, parking lots etc. The size of these concrete pits and grates vary depending on where they are being used, from around the house, to around the city.

These drains are fed by water when it rains; sources can include – gutters and roads, even the guttering from your home can be connected to a storm drain or underground water tank. Many storm drainage systems are designed for moving untreated stormwater directly into rivers, lakes and oceans.
