Introducing the Accesso MetroSewer Base (MSB)

At Turtle Enviro, we are passionate about redefining the landscape of inspection chambers for foul and surface water drainage. Our latest innovation, the Accesso MetroSewer Base (MSB), is a remarkable addition to our Accesso range.

Expertly engineered to harmonise with the state-of-the-art Naylor MetroSewer pipework, the MSB sets a new benchmark in drainage solutions. It promises not only exceptional performance but also impressive durability that stands the test of time, along with a hassle-free installation process that simplifies on-site work.

In this blog post, we invite you to explore the Accesso MSB range in greater detail. We’ll uncover its diverse applications, highlight its innovative features, and showcase the multitude of benefits it offers for enhancing your drainage systems.

What is the Accesso MSB and its applications?

The Accesso MSB inspection chamber delivers unparalleled above-ground access for efficient inspection and maintenance of surface water drainage systems, effectively removing the need for excavation.

Our Accesso MSB chambers offer the ideal inspection solution for both adoptable drainage systems (serving multiple properties) and non-adoptable systems (serving single properties).

These new chambers are offered with three various pipework diameters -150mm, 225mm, and 300mm, with a maximum installation depth of 3 metres to the pipe soffit, which is in accordance with Design and Construction Guidance (DCG).

All chamber connections are specifically designed for Naylor MetroSewer pipework, while also seamlessly integrating with Naylor MetroDrain and Naylor NDrain systems. Our Ø150mm pipework option comes with chamber diameters of 450mm and 600mm, ensuring flexibility. Meanwhile, both the Ø225mm and Ø300mm options are exclusively available with a 600mm chamber diameter, providing the reliability and performance you need for any drainage application.

Key features of the Accesso MSB range

The key features of this range include:

• Pre-assembled, single-piece chambers: Quick and straightforward to install, reducing labour costs and time on-site.
• Durable Polyethylene base: Rotationally moulded, offering high chemical and impact resistance for long-term performance.
• Stepped base design: Supports low flow dynamics effectively, featuring a minimum 50mm step from side to main channel to enhance flow efficiency.
• Optimised flow support: Built-in fall from the main inlet to the outlet to support consistent flow.
• Flexible depths: Available in five standard depths (1m, 1.5m, 2m, 2.4m, and 3m), easily cut onsite to meet specific requirements.
• Granular backfill compatible: Simplifies installation across diverse site conditions, offering both flexibility and cost efficiency.

Benefits of the Accesso MSB range

Key benefits include:

Ancillary options for added versatility

One of the key advantages of this system is the range of ancillary options available. These include wall seal connections for 110mm and 160mm EN1401 pipes, restriction caps for chambers over 1000mm to the soffit of the inlet pipe, and reduction caps that reduce the main access diameter for smaller covers. Additionally, sealing rings ensure watertight and secure connections, further enhancing the system’s reliability and versatility

High-quality design

Designed to meet the highest industry standards, the Accesso MSB adheres to Design & Construction Guidance (DCG) – Type D chambers, Building Regulations Part H, and BS EN 681-1 Sealing Systems. This ensures exceptional quality, consistency, and reliability in every installation.
