Networks and collectors
Construction and reconstruction of sewer and stormwater networks, collectors and inspection chambers.

Networks, treatment plants and hydraulic engineering. Practical solutions for cities, transport facilities and water infrastructure.
We bring design, construction and reconstruction together around your infrastructure needs. Site conditions, existing utilities and operating requirements shape the approach.
The service brings together ALTCOM’s hydraulic engineering experience and the capabilities of TEKHEX, our delivery partner.


Construction and reconstruction of sewer and stormwater networks, collectors and inspection chambers.

Design and construction of wastewater treatment plants with solutions suited to the design load.

Collector rehabilitation and trenchless methods where network condition and site constraints allow.

Riverbank protection, protective and regulating structures within infrastructure projects.
Open-cut construction, rehabilitation or trenchless installation: the method follows an assessment of the network, ground conditions and site constraints. Relevant projects show the use of SPIRO pipes and chambers.
Trench support and utility installation: a closer view of work on site.


From a 3D construction sequence to actual foundation works: two views of engineering at the water’s edge.

Drilling, pile handling and riverbank foundations. Archive footage shows the sequence and scale of the work.

Foundations, piers, girders and the completed span: a 3D sequence illustrating how a river crossing takes shape.
