Mullaly fibreglass (FRP) units are designed and built for quality. As one-piece, corrosion-resistant and watertight products, they have lower maintenance costs and a longer life, and they reduce excavation at installation, which keeps the environmental footprint small.
As an Australian owned and operated company, we offer a range of fibreglass systems to help you manage wastewater. Each product is tailored to its site conditions.

Mullaly sewage pump stations and emergency storage tanks have been evaluated under WSAA's national product appraisal scheme. They hold appraisal PA 1020 (Issue 4, current to 2031) and are designed to WSA 04-2022.
In most cases a Mullaly fibreglass pump station is set and backfilled within 1 to 2 days of delivery, so crews can get into the base quickly to install the remaining pump equipment.
A one-piece, factory-made wet well does not rely on sealants applied on site to be watertight.
The liquid and vapour exposed surfaces of a pump station face harsh, corrosive conditions. Fibreglass resists them, so the structure lasts.

As an Australian owned and operated company, we manufacture a range of water and wastewater FRP storage products.
Independently evaluated under Australia's national product appraisal scheme, WSAA PA 1020.
Whether installed in a fully flooded hole to grade, or in a dry hole with no groundwater, Mullaly pump stations are designed for a wide range of site conditions.
Hundreds of successful installations and no known structural failures in over 30 years.
Mullaly is Australian owned, and Mullaly products are made in Australia by a team that has built up a great deal of experience and expertise over the years. Our NSW factory is at Tomago, near Newcastle.
We give a 30-year corrosion warranty on Mullaly FRP pump stations because we are confident of their quality and long-term performance.
Mullaly uses premium grade vinyl ester resins and glass reinforcement in its fibreglass pump stations, for strength and corrosion resistance.

"I would have no hesitation in recommending a Mullaly Fibreglass pump station as we have been installing these for over 15 years and have found the ease of installation, combined with the reduced safety risks and excavation works required make these units an overall cost effective solution and great value for our clients. We have had no known structural failures to date which is testament to the quality and track record in the Australian market and its long term proven performance."
