Presco Environmental Infrastructure are NZ Leaders in Sustainable Dairy Farm Infrastructure.
Our sustainable weapon of choice is concrete, one of the most durable materials on the planet!

Presco Environmental Infrastructure has grown enormously since its inception in 2006 when Steve Prestidge purchased a small Hawera business that had been manufacturing water troughs and tanks for the last 60 years. We are no longer just a pre-cast manufacturing plant. With our current design and installation teams, we have the capability to deliver client specific total-package solutions to all of our customers in all of our fields of expertise. Our ability to progress into advanced infrastructure projects was driven by Steve’s son, Oliver, who is a qualified builder. As the team has grown, our core value of continuous improvement has allowed our skillset to develop in line with our client needs, and in recent years the development and increasing popularity of our Prosump  effluent storage solution has lead to us becoming specialists in Farm Dairy Effluent (FDE) system design and construction.

We are a family business owned by Steve Prestidge and managed by his son Oliver. Our manufacturing plant and head office is based in Hawera, Taranaki, however we service the whole of New Zealand.

Presco Environmental Infrastructure is one of the Presco group of companies owned by Steve Prestidge and his family. Associated companies include Presco Environmental Services and Presco Hire.
