WATERSOLV™ CHEMIGATION · FS-1 SYSTEM
Deliver WaterSOLV™ through your irrigation system with precision, consistency, and less manual work.
The FS-1 is HCT’s chemigation platform for injecting WaterSOLV™ chemistry into flowing irrigation water. It reads your flow meter and doses automatically in proportion to water movement, so treatment stays accurate as conditions change and runs whenever the water runs. WaterSOLV™ is the treatment. FS-1 is the delivery system. Your irrigation is the transport path.
3 feed pumps standard, expandable to 6 · Works with most existing flow meters · No probes to clean or calibrate · 110V, 25-amp dedicated circuit
WHAT IT IS AND HOW IT WORKS
A control system that meters WaterSOLV™ into flowing irrigation water, in proportion to flow.
FS-1 is not the treatment itself. It is the equipment platform that meters and injects WaterSOLV™ and related chemistry into the irrigation stream. It connects to your existing flow meter, reads water movement, and runs the feed pumps automatically so dosing stays proportional to actual flow. The result is consistent treatment delivery across real irrigation conditions where manual dosing would be difficult, variable, or labor-intensive.
01
Connect the chemistry source
Drop the suction line into a container or tote camlock. Plug-and-play setup connects the treatment source to the system.
02
FS-1 reads flow and triggers the feed pumps
Flow meter signals run the pumps automatically, so injection starts and adjusts with water movement instead of relying on manual timing.
03
WaterSOLV™ injects at the programmed rate
Chemistry is metered proportionally to flow, keeping dosing consistent across changing irrigation conditions throughout the cycle.
The FS-1 controller. It reads the flow meter and runs up to six feed pumps from totes or drums.
WHY FS-1
Benefits that matter to buyers, operators, and field teams.
01
Flow-proportional accuracy
Injection rates stay aligned with actual irrigation water movement rather than a rough manual estimate, giving consistent treatment coverage.
02
Works with existing infrastructure
Designed to connect into sites that already have injection ports and a flow meter, reducing retrofit complexity and lowering the barrier to implementation.
03
Zero probe maintenance
No probes, no cleaning cycles, no calibration routines. A simpler operating experience than systems built around probe maintenance.
04
Automatic pump intelligence
Feed pumps stay tied to flow signals, so performance does not depend on constant operator attention. Treatment runs when water runs.
05
Scalable pump capacity
Three chemical feed pumps standard, expandable to six per flow meter, so the system grows with the treatment program.
06
Predictable annual service
Routine maintenance means replacing simple wear components: plungers, O-rings, and lines. Easy to budget, plan, and do in the field.

WHY IT IS THE BETTER OPTION
Compared with the ways chemistry usually gets into irrigation water.
Manual dosing
ACCURACY
✕ A rough estimate that drifts as flow changes through the cycle.
✓ Metered in proportion to actual flow, all cycle long.
LABOR
✕ Someone has to be there to start, stop, and adjust.
✓ Treatment runs when water runs. No operator attention required.
CONSISTENCY
✕ Coverage varies block to block and day to day.
✓ Repeatable delivery across the whole irrigation network.
Probe-based controllers
MAINTENANCE
✕ Probes to clean, calibrate, and replace.
✓ No probes. Nothing to clean or calibrate.
RELIABILITY
✕ Drift and fouling send the dose off target.
✓ Flow meter signal drives the pumps directly.
SERVICE
✕ Specialist calibration routines.
✓ Plungers, O-rings, and lines once a year.
Sulfuric acid injection
CHEMISTRY
✕ Continuous, high-volume acid that corrodes pumps and fittings.
✓ Non-corrosive WaterSOLV™ at up to 90% less product.
SAFETY
✕ Fumes, burns, PPE, hazmat storage.
✓ Safer handling with a lower compliance burden.
RESULT
✕ Lower pH, same scale, sealing, and black layer.
✓ Minerals stay soluble, soils stay open.

BUILT FOR
WaterSOLV™ program sites
Operations already on WaterSOLV™ that want cleaner, more repeatable injection control through their existing irrigation system.
BUILT FOR
Sites with existing flow meters
Injection ports and a flow meter already in place. FS-1 connects into that infrastructure with minimal modification.
BUILT FOR
Teams scaling treatment programs
Growers, turf managers, and operators scaling delivery without adding manual dosing complexity or labor.
