SUMPS AND PIT DRAINS FOR EXTERNAL SURFACE STORMWATER COLLECTION

Allproof manufacture a range of drainage pits and sumps for residential and commercial applications. All pits are designed to exceed New Zealand building standards and regulations.

Plastic pits are NZ-made using 100% recycled materials from local sources. Available in round or square they provide an economic drainage solution with a variety of grate options that tie in with Allproof’s linear channel systems providing continuity. Drainage grates include cast iron, stainless steel, aluminium and plastic. The 250×250 square plastic sump is ideal for residential projects in driveways or around the perimeter of properties to collect surface water. Slip-resistant and heelproof stainless steel wedge wire sumps are perfect for high-traffic pedestrianised areas and urban street planning.

The Polymer Concrete drainage pit sumps are suited to commercial projects. These durable drains have grates with high load class ratings, perfect for loading bays, container yards and industrial areas. Can also be used for infrastructure projects and as a high-capacity stormwater collection point alongside linear channel drains next to carriageways.
