Fibreglass (FRP) Pump Stations and Water Tanks

Mullaly has made one-piece fibreglass (FRP) pump stations in Australia for over 30 years, along with underground water tanks and Aquator® oil water separators. We work with engineers, councils and contractors on design, supply and installation across Australia.

How a project runs with us

What we do on a pump station project, from the specification to the unit in service.

Gate valves and pipework inside a Mullaly fibreglass valve pit

Design

Send drawings or start with the spec builder. Pump stations are designed and certified by a practising composite materials engineer, with RPEQ certification available when required.

Finished Mullaly fibreglass wet well in the factory before dispatch

Manufacture

Built at Tomago, near Newcastle, from premium grade vinyl ester resin with a corrosion barrier as standard and walls typically at least 20mm thick.

Delivery

Pedestals, guide rails and pipework are fitted to the approved drawings before it leaves the factory, whether it's going to a subdivision or Badu Island.

Installation

In most cases a pump station is set and backfilled within 1 to 2 days of delivery. Ballast calculations come with the installation instructions.

In service

A 100-year design life and a 30-year corrosion warranty. The Ramingining pump station was in near perfect condition 20 years after it went in.

Fibreglass and the environment

Fibreglass units reduce the ground disturbed at installation, and Mullaly tanks and separators help manage stormwater on site.

Smaller excavation

The integral valve chamber shortens the dig and needs less space, so there is less disruption to local flora and fauna.

Nothing leaks into the ground

A one-piece, factory-made wet well doesn't rely on sealants applied on site to stay watertight.

No coating to renew

Liquid and vapour exposed surfaces face harsh, corrosive conditions. Fibreglass resists them, so the structure lasts.

Oil water separation

Aquator® Class 1 separators treat runoff from refuelling areas, depots and substations. The T20 handles up to 60 L/s, tested by UniSA and the University of Newcastle.

Providing FRP wastewater product solutions for over 30 years

Mullaly specialises in the manufacture of FRP pump stations, FRP water storage tanks and wastewater storage tanks. In 2016, Tank Solutions acquired the Mullaly Engineering business, and we continue to make Mullaly products to the standards customers have expected for more than 30 years.

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. We set out the differences in FRP vs concrete pump stations.

A pump station can be a combo unit or a separate wet well and valve pit. Our underground tanks hold potable water, fire water and rainwater, and stormwater for retention or on-site detention (OSD). Several tanks can be connected for large water storage. Where runoff carries fuel or oil, our oil water separator guide explains which type of separator suits the site.

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. Queensland and Northern Territory projects are supplied through our distribution partner, Professional Pump Services & Irrigation. Mullaly pump stations in Queensland include North Queensland Stadium and Innes Estate in Townsville.

Benefits of a Mullaly FRP pump station

WSAA appraised

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.

Quick, easy installation

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.

Watertight design

A one-piece, factory-made wet well does not rely on sealants applied on site to be watertight.

Corrosion resistance

The liquid and vapour exposed surfaces of a pump station face harsh, corrosive conditions. Fibreglass resists them, so the structure lasts.

Why Mullaly?

As an Australian owned and operated company, we manufacture a range of water and wastewater FRP storage products.

WSAA appraised

Independently evaluated under Australia's national product appraisal scheme, WSAA PA 1020.

Engineered for strength

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.

Long-term performance

Hundreds of successful installations and no known structural failures in over 30 years.

Australian made

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.

30-year warranty

We give a 30-year corrosion warranty on Mullaly FRP pump stations because we are confident of their quality and long-term performance.

Premium materials

Mullaly uses premium grade vinyl ester resins and glass reinforcement in its fibreglass pump stations, for strength and corrosion resistance.

What people say about us


"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."
Eric Lollo, NQ Excavations
