Keeping courses green:
The hidden golf course irrigation solution
When most people step onto a golf course, their attention is on their par. Few of us stop to think about the hidden engineering work beneath our feet.
Beneath the meticulously kept surfaces of the golf course is a vital network that helps keeps everything running, growing, and green. Golf course irrigation – and all the interlinked systems that entails – is required to maintain the healthy look of a green.
At the heart of that system is a humble yet critical component. If you’re an infrastructure professional designing drainage for a golf course, a city green or a public park/garden, it’s time to consider the role of the valve box.

The value of valve boxes in golf course irrigation
Irrigation isn’t just about turning on a tap. For golf courses and beyond, water must be delivered strategically and sparingly. That requires a network of control valves that regulate water flow to different zones – based on soil moisture, turf type, sunlight, and weather patterns.
These control valves don’t operate in isolation. They need protection from weather, foot traffic, vandalism, and the elements.
That's where valve boxes come in - acting as durable enclosures that make irrigation systems both accessible and secure.

Introducing the Cubis MONObox™ Carson Valve Box range
You’ve probably walked over multiple Carson valve boxes without noticing. In fact, so have the world’s top golfers.
Part of our MONObox™ range, the Carson Valve Box has been the go-to choice for specifiers for decades. While golf course irrigation is its most common use case, Carson has been applied in parks, farms, government landscaping projects, and commercial landscapes around the world.
In fact, with over 30 million units installed worldwide, it's statistically the world's most specified valve box.
That’s because Carson ticks all the boxes specifiers and contractors care about:
-
Lightweight yet strong
Made from HDPE and boasting a renowned strength-weight ratio
-
True time and cost-saver
Installs take under an hour, can be completed by a single person, and require no specialist equipment
-
A complete solution
No frames needed – just ‘drop-in’ HDPE covers and go
-
Secure and adaptable
Available in multiple shapes, sizes, and with multiple cover / accessory options
-
Ready for almost any environment
Up to B125-rated for pedestrian and light vehicle load
-
Flexes to on-site conditions
Can be adapted to overbuild over existing networks, introduce duct entries for cable entry, or top-section fine adjustment
-
All-weather construction
Freezing temperatures needn’t freeze works (as with brick-built alternatives)
-
Discreet and durable
Carson does the job — then disappears into the background thanks to its varied cover options (including artificial grass, concrete infill and ductile iron)

Keeping the greens green — quietly and reliably
You may not notice them, but valve boxes are critical to the infrastructure that keeps golf courses playable and parks inviting. While the Carson Valve Box isn’t in the spotlight, its performance keeps everything above ground looking as it should.
