SELF yard sump

ANRIN offers a range of different cover gratings for the SELF yard sump: a slotted grating made of ductile cast-iron, a mesh grating, a stainless steel longitudinal-bar grating and a galvanised steel slotted grating. The slot widths of around 10 mm prevent large items from being swept in while also ensuring an optimal water intake. The load capacity of all gratings is designed to withstand car loads in private residential construction.

SELF yard sump installation instructions

With ANRIN drainage systems, accumulating rainwater should be drained safely and quickly. Moreover, the structural elements have the task of accommodating dynamic loads arising from traffic-related demands and dispersing them to the area of the foundation.

Amongst others, the following technical rules and regulations in their respective valid versions must be observed for the selection, design and installation of ANRIN drainage systems.

The following installation guidelines are schematic representations. These are provided as examples and are non-binding. The information provided here is based on our long-term experience in excavation and road construction as well as the state-of-the-art technology. Despite this, designers and planners are always obligated to check the products and the installation instructions for their appropriateness. The example details are simplified recommendations for execution.

Constructions are to be re-created on a project-specific basis.

Align the pipeline to the courtyard inlet. Excavate the trench and backfill the concrete pad comprised of a mix of 3 parts sand + 1 part cement + 1 part water.

Image 2 SELF Installation guide


Position the courtyard inlet on the concrete pad. Connect the pipeline. When connecting a downpipe, open the premoulded indent on the top-mounted box and insert the pipe socket.
