Australia’s Leading Sewer Vent Shaft Design, Fabrication & Installation Company
SVSR specialises in crafting top-notch sewer vents for Sydney Water, regional councils, engineering initiatives, pump stations, and prominent commercial partners. Leveraging our 25 years of industry expertise, we stand as the go-to authority for superior, budget-friendly, and regulatory-compliant sewer vent resolutions.
Sewer vent shafts
Numerous prevailing sewer vents have surpassed the 80-year mark, posing potential hazards to individuals and assets. We specialise in crafting tailor-made sewer vent shafts, rigorously evaluating existing blueprints for suitability.
Our comprehensive CAD capabilities are bolstered by an adept in-house design team, equipped for any necessary modifications. Backed by decades of wastewater infrastructure expertise, our adaptability and proficiency shine through. Precisely adhering to specifications, we manufacture vent shafts while also pioneering inventive sewer vent solutions for intricate and demanding locations.
High quality and compliant fabrication
Our vent shafts are meticulously crafted from premium stainless steel, ensuring durability and reduced long-term maintenance expenses. Enhancing functionality, we offer various sewer vent cowls, encompassing rotating educt vent cowls, induct cowls, and custom-designed alternatives, each contributing to heightened efficiency. Our expertise extends to specialised sewer vent shaft designs, strategically accommodating the potential integration of odour control units in the future.
Sewer vent shaft designs
The following are Sydney Water approved designs (plus three prior designs no longer in use):
Guy wire sewer vents
Guy wire sewer vents are the most type common in use.
Sizes are DN 150, 225 & 300 and heights range from 14 to 18m.
DTC 9-18m post sewer vent
A free-standing structure. Sizes are DN 150, 225 and 300 with a height between 9 and 14 metres.
Post sewer vent
A free-standing structure. Sizes are DN 150, 225 and 300 with a maximum height of 9m.
May be installed only where the catchment being vented is less than 80-100 houses.
Unsuitable in the vicinity of multi-storey buildings (wall vent preferred in such situations).
Wall sewer vent
Wall sewer vents are attached to a building and may be enclosed inside the building under certain circumstances.
Vent may only be attached to a solid wall i.e. double brick or concrete, not clad timber frame.
Preference is for the sewer vent tube not to be enclosed inside a wall cavity.
Sizes are DN 150, 225 and 300.
Fibreglass sewer vent
A freestanding structure used in aggressive conditions e.g. coastal areas (salt-laden sea breezes).
Sizes range from DN 150 to DN 400 and heights from 13 to 16m.
Special sewer vent
Any sewer vent larger than DN 300 is considered a special type and requires separate design consideration.
Cast iron column sewer vent (legacy)
CI vents are no longer being installed but are maintained in heritage areas such as Paddington by the use of an adaptor plate to use a stainless steel tube.
Tapered sewer vent (legacy)
Tapered sewer vent shafts are no longer being installed or maintained due to corrosion of the galvanised mild steel tube resulting in unpredictable catastrophes.
Concrete sewer vent (legacy)
Concrete sewer vents are normally inherited from council sewerage schemes. They are prone to concrete cancer and are not maintained but are replaced when required with either a post or guy wire vent.
