Designed for buried gravity sewer systems, the EZIpit is introduced at regular intervals to facilitate the inspection, cleaning and maintenance of sewerage systems as well as accommodating changes in direction of flow where different sewer streams converge.
Compared to conventional maintenance structures, Iplex has designed its EZIpit bases, risers and components from a high-quality polypropylene that provides significant benefits in sewer environments. Polypropylene is highly resistant to chemical attacks – such as sulphuric acid erosion, which is common in gravity sewer systems – and has a service history of approximately 40 years, ensuring it is the optimal choice for utility infrastructure.
Key attributes
EZIpit Maintenance Structures offer superior in-ground performance. Across the range, they comprise four key components – a base, a single wall corrugated riser, a reducing cone and ductile iron covers.
The base has smooth flow channels for optimal flow performance and swivel sockets allowing flexibility in design and installation, while the internal flow channels included in the bases can maintain the trench alignment without the need to further widen it.
The single wall corrugated riser can be cut on site for height adjustments and also accommodate any soil settlement over time without resulting in high loads to the base or finished surface and cover arrangements. While the reducing cone is for the maintenance hole, the range of ductile iron covers are designed to fit all EZIpit Maintenance Structures for both trafficable and non-trafficable areas.
The lightweight modular components of the EZIpit Maintenance Structures are easy to handle and manoeuvre in difficult-to-access sites, reducing the need for heaving lifting equipment. This lightweight system also allows the pipe installer to easily assemble the components, significantly reducing installation times as well as costs in plant, labour and, risks associated with open excavation.
A long-lasting solution
There is a strong acceptance of EZIpit due to its superior quality and corrosion resistance, which delivers years of corrosion free service. All polypropylene components of the maintenance structures are manufactured using state-of-the-art plastic processing moulding and extrusion technologies, ensuring the product’s components are free from defects and fit for purpose – continually demonstrating durability and strength with on-site static and dynamic loads.
The EZIpit Polypropylene Maintenance Structures range comprises: EZIpit 425 Access Shaft, EZIpit 600 Access Chamber; and the forthcoming EZIpit®1000 Maintenance Hole, which is due for market release in mid-2020.
