Sewer Inspection and Junction Fittings

Purpose-Built HDPE Sewer Fittings

Made from corrosion-resistant HDPE and joined by heat fusion, these fittings form a monolithic, root-proof sewer system that outlasts concrete and clay alternatives, with a long service life even in aggressive soil conditions.

The smooth inner surface of our pipes prevents debris accumulation and ensures efficient flow, reducing pumping costs and maintenance needs. Our systems are designed to handle varying flow rates and withstand the demanding conditions of municipal wastewater collection.

Key Features

Corrosion-resistant materials for long service life
Smooth interior surface prevents blockages
Flexible joint systems accommodate ground movement
Easy installation reduces construction time
Cost-effective maintenance over system lifetime

Applications

Residential Areas

Collection systems for housing developments and residential communities.

Commercial Districts

Wastewater management for business and commercial zones.

Sewer Inspection and Junction Fittings Resistant to the Test of Time

Hydrogen sulphide, cleaning chemicals and decades of continuous flow destroy conventional sewer materials. Our smooth-bore PE systems shrug off all three while maintaining design velocity.

Effective drainage engineering is about managing peak events, not average flow. Our systems are hydraulically modelled against design storm scenarios, with pipe sizing, gradient and access point spacing optimised to carry cloudburst loads without surcharge or sediment settlement.

Smooth-bore HDPE delivers a Manning coefficient around 0.009 - significantly better than concrete - which allows smaller diameters or flatter gradients for the same discharge capacity. Combined with chemical resistance against sewage aggressors, this keeps buried assets serviceable for over fifty years.

High Flow Capacity

Smooth bore walls reduce friction losses and maintain design velocity

Ring-Stiffness Options

SN4 to SN8 buried grades engineered for traffic load conditions

Chemical Immunity

Resists hydrogen sulphide attack and aggressive soil chemistry

Siphonic Expertise

Full-bore siphonic roof and ground drainage designed to BS EN 12056

Joint Integrity

Fusion-welded or rubber-ring joints sealed against infiltration and exfiltration

Long Service Life

50+ year design life with negligible maintenance intervention
