Lawn basins are used to collect water in fields, swales, yards and lots and direct the flow of water to the storm sewer system.

Unlike catch basins, lawn basins are cast 'groove end up' which allows a grate to be set in the top end when installed.

Not recommended for paved areas, they work well when placed in landscaped areas, gravel parking lots and fields with turf surrounding them. Using a cast iron grate they can be driven over by maintenance vehicles and lawn mowers but are not normally used where high traffic volumes or large vehicles are present.

Lawn basins range in size from 250mm diameter up to 900mm. Depths vary from 300mm up to 1.2m, with or without cast in base. Smaller sizes are manufactured non-reinforced, larger sizes are reinforced to ASTM C478-08.

Advantages:

• Cost effective and simple to install
• High strength drycast concrete provides consistent quality and dimensions
• Many standard, stock sizes available to address almost any drainage design
• Joints are compatible with most commonly accepted casting supplier's designs
