Trade Waste Pits & Risers

Precast pit risers offer a simple solution for adjusting the final height of a stormwater, cabling, or trade waste pit to meet the required pit depth, saving time compared to ordering a custom height. They are ideal when you need to increase the depth of your standard size solid wall pits to align perfectly with a newly finished surface level, eliminating the need to pour extra concrete on-site.

Pit riser walls include a slight protrusion at the base, allowing them to fit snugly into the pit wall rebate when they are stacked on top of a compatible pit base.

A grease trap is specifically for the collection and filtration of wastewater containing food waste, discharged from industrial and commercial kitchens. An interceptor pit is a more general term and can be used to refer to applications requiring the capture and filtration of petrol, oil, or other solids in a workshop environment.

Trade waste pits are used by businesses like restaurants, factories, petrol stations or mechanical workshops - any application that results in the discharge of dirty wastewater.

Trade waste pits are fully-contained precast units with the ability to capture and trap substances such as grease, oil, lint or other solids, preventing them from entering and contaminating the main sewerage network.

Since heavy-duty concrete utility pits are robust and heavy, it is crucial that all products are lifted using the appropriate lifting tools and techniques to ensure safe transportation and handling. Due to the sheer weight of precast concrete products, any product failure or improper lifting equipment poses a high risk to people nearby.

SVC incorporates steel lifting anchors into our precast concrete products, which are compatible with either 1.3T, 2.5T or 5.0 lifting clutches (depending on product weight). Lifting clutches must be connected to the appropriately load-rated lifting chains. All clutches are available to purchase from SVC.

Note: Some SVC pit products may still include lifting holes, which are compatible with 1.0T lifting hooks. Customers must not use these holes to thread chains through for lifting; this is an incorrect technique and is very dangerous, as it greatly increases the risk of pit wall breakage from chain-induced stress.
