About Us

Marshall Projects was established in Invercargill in 2005 by Tom Marshall to undertake water and wastewater projects.


Tom is the grandson of Owen Marshall, who in 1936 established Owen Marshall Plumbing (now called Marshall Industries). Owen was a skilled pioneer, building his own machinery and producing some of the first longrun roofing steel in New Zealand. Marshall Industries is now also managed by Tom and predominantly undertakes roofing manufacture, installation and engineering work.

By establishing Marshall Projects and providing water and wastewater processing plants for clients, Tom has returned to the roots of his family business and is proud to continue the long history of innovation started by his grandfather.

Marshall Projects takes pride in working in partnership with our clients to ensure the process selection and project design meet requirements and result in projects that perform above expectations for years to come.  Well after projects are complete we maintain our relationships with our clients and assist them with their ever changing needs.

Our friendly team of experienced, professional, qualified staff will advise you on the suitable process requirements for your needs, from the initial consultation and pricing, through to project delivery and follow up.

Marshall Projects utilises the skills and resources of Marshall Industries for the fabrication and installation of water and wastewater projects. The diverse markets of the two companies enable us to maintain a valued and skilled resource base to ensure projects are delivered on time and to a high standard.
