Irrigation Upgrade

The upgrades we do most

• Capacity expansion. The farm grew from two acres to five — the drip network extends, the mainline route is checked for the added flow, and the head (filter, pump) is upsized where it can't carry the new load. The cheap insurance from the original design — a mainline routed for the full farm — is exactly what makes this phase smooth; where it wasn't in the design, the upgrade includes the mainline extension, which is the dig-and-fuse job we'd rather do once.
• Zone additions. A new block needs its own zone — its valve, its line specification (a new crop has a new emitter spacing), and its place in the pump's run-time budget. Adding a zone to a system designed for zones is an afternoon; adding it to a system with no zones is where the design conversation starts.
• Filtration upgrades. The most common and the highest-value: the system that's been running without a filter (or with an undersized one) gets the right one — the disc, media or two-stage setup matched to the source, with the gauges and the backwash provision. It's the upgrade that turns a system that's "always a bit clogged" into one that runs clean, and it's usually the first one we recommend.
• Automation. The manual-valve farm gets the multi-zone controller and the solenoid valves — the wiring run with the pipework, the schedules set per zone, the labour hours come home. The sensor upgrade (soil moisture) is the next rung for the operations that earn it. See automated irrigation.
• Fertigation. The system that's been on broadcast feeding gets the fertigation head — the injection point after the filter, the tanks, the flush line — and the feed program that follows the crop. The injection point's position is why it's a designed addition, not a bolt-on.
• Pressure management. The burst-line farm (too much pressure) gets the regulator; the dry-end farm (too little) gets the fix for the real cause — a sized mainline, a better pump, or the PC emitters where the layout demands them. The pressure diagnosis is in the repair path; the upgrade is the fix when the cause is structural.
• Pump replacement. The pump that's outlived its duty — or was never right — gets the spec from the calculation (flow × head, from the actual system, not the label), with the power option re-examined (solar is the upgrade that pays for itself on fuel).

How an upgrade is scoped

Every upgrade starts the same way the new builds do: the assessment — what's in the ground (pipe sizes, line type, the filter or the absence of one, the pump's real behaviour), what the farm is now (the blocks, the crops, the water source's current yield), and what the farm wants (the expansion, the automation, the crop change). The upgrade design is then a delta: what the existing system carries, what the new load adds, and which components survive the step. That delta is what the quote prices — line by line, against the existing inventory, not against a blank field.

The install sequences around the running farm — the new zone installed while the old ones keep running, the head upgraded over a weekend where the crop can't lose a day. The same handover standard applies to the upgraded parts: tested at design pressure before we leave, documented on the (now real) as-built.

Upgrade vs rebuild — the honest line

Some systems are better rebuilt than upgraded — a mainline that's undersized across its whole length, a field with no zones at all, a head that's the wrong scale for the farm. The assessment finds the line, and we say which side you're on, with the numbers for both paths. The rule of thumb: if the upgrade touches most of the system, the rebuild (a new design on the existing farm, the same install standard) is usually the better money — and it's the same service chain, just a bigger delta. See irrigation design for the rebuild path.

What to have ready

• What's installed — the line type, the pump, the water source (photos help; the exact spec if you have it).
• What the farm is now — the blocks, the crops, the acreage.
• What you want to add — the expansion, the automation, the new crop, the fertigation.
• What's failing, if anything — the symptoms that are the reason for the visit in the first place.

With that, the assessment (and the upgrade quote) is a short job — and the system that comes out the other end is the one the farm actually needs, built on the one you already have.
