Certified System Design You Can Trust
built for compliance, performance, and peace of mind
When it comes to effluent system design, doing it right from the start makes all the difference, for compliance, for your bottom line, and for the environment.
That’s why Reid & Harrison Services is proud to be a certified provider under the Farm Dairy Effluent System Design Accreditation Programme (FDES).
Effluent Systems That Fit Your Farm, Not the Other Way Around
This national programme is designed to lift the standard of effluent systems across New Zealand by ensuring that every design meets stringent FDE Code of Practice and Design Standards. In short, it ensures your effluent stays out of waterways, nutrients stay in the soil where they belong, and your system works effectively year-round.
Our team follows accredited design practices tailored to your farm’s layout, soil type, and climate. We don’t do cookie-cutter installs. We build smart, future-proof systems that are fit for purpose, fit for region, and fit for regulation.
Why Work with an FDES-Accredited Designer?
We’ve seen too many farms left to clean up the mess from poorly designed systems that include pond overflows, underpowered pumps, non-compliance issues, and costly fixes. With Reid & Harrison, you’re backed by decades of effluent know-how and a team that understands the details that matter.
Whether you’re upgrading your system, expanding the farm, or building from scratch, we’ll make sure your effluent management is compliant, cost-effective, and set for the long haul.
Planning a New System? Start with the Farmer’s Guide
If you’re considering a new effluent system, or upgrading an old one, the Farmer’s Guide to Farm Dairy Effluent (FDE) Systems is a must-read. It offers clear, practical advice to help you design a system that suits your farm, meets compliance, and supports better environmental outcomes.

Using the Dairy Effluent Storage Calculator, we model your storage needs based on herd size, rainfall, application methods, and land use. Lastly we test scenarios to make sure it holds up in all conditions.
