Water audits are often one of the simplest ways to improve the performance of an irrigation system.
Over time, even well-designed systems can drift out of balance — blocked nozzles, pressure variation, uneven application, or areas receiving more or less water than intended. Often the changes are gradual and not immediately obvious.
A water audit helps identify how a system is actually performing in the field, rather than how it was originally designed to perform.
The result is usually better water efficiency, more even coverage, and a clearer understanding of where improvements can be made — whether on parks, sportsfields, racecourses, golf courses, or farm systems.
Good water management starts with good information.

The consultancy work Wai Design are involved in is often quite varied — from wastewater irrigation and disposal fields, to high country stock water systems, water audits on irrigation systems, and racecourse irrigation.

Different sites and different challenges, but always the same focus: understanding how water moves across the land and designing practical systems that perform well over time.

At Wai Design, we can help with a wide range of water consultancy needs — bringing practical, site-specific thinking to each project.

How the Site Is Used.
Water design should reflect how a place is used.
A landscape’s purpose affects how irrigation should be designed.

Sports fields, public spaces, gardens, and rural properties all have different performance expectations.

Understanding how people use a space helps guide irrigation design so the system supports both the landscape and the people using it.

Good design fits the place.

Things we look for before designing water: Available Water

One of the most important questions is simple: how much water is actually available?

The capacity of the water supply influences system layout, irrigation zones, and application rates.

Designing within the limits of the available supply ensures the system works properly without overloading pumps or pipelines.

Practical design always starts with understanding the resource.
