Automatic Irrigation Systems
An automatic irrigation system waters landscaped areas on a schedule, without someone moving hoses around the site. Water is drawn from a tank, borehole or mains supply, boosted where necessary, and carried through buried pipework to zones of pop-up sprinklers, rotors or drip lines. A controller opens each zone in turn through solenoid valves, and sensors can hold watering back when it rains.
Trident Plumbers Limited designs and installs irrigation as part of the wider water services on commercial, institutional and residential developments. Because we also handle water storage, pumping and distribution, the irrigation system is sized and connected so that it does not starve the building’s own supply.
At a glance
- Installation of automatic irrigation systems for landscaping and green spaces.
- Maintenance and repair of irrigation systems to optimize water use.
- Integration of smart irrigation technology for efficient water management.
What we deliver
From design to maintenance, one contractor
Trident can take on the whole package or the part you need, working to your consultant’s design or to our own.
01Design & sizing
Zoning by plant type, sun and slope, sprinkler and drip layouts with even coverage, pipe and pump sizing to the available water supply, and a watering schedule that matches the landscape.
02Supply
Sprinklers, rotors, drip lines, solenoid valves, controllers, sensors, pumps and pressure-rated pipework, selected to the specification and the quality of the water source.
03Installation
Trenching, pipe laying, valve boxes, controller wiring and head setting carried out by our own crews, coordinated with the landscaper and other buried services.
04Testing & commissioning
Pressure testing and flushing of the mains, zone-by-zone coverage checks, adjustment of arcs and throws, and controller programming, with a schedule handed over to the site team.
05Maintenance
Seasonal schedule changes, checks for leaks, blocked emitters and damaged heads, valve and controller repairs, and adjustments as the planting matures.
Systems and components we install
- Pop-up spray and rotor sprinkler zones for lawns and sports areas
- Drip and micro-irrigation for beds, hedges and planters
- Irrigation controllers with rain or soil-moisture sensors
- Solenoid valve manifolds, valve boxes and field wiring
- Irrigation pumps and connections to tanks, boreholes or mains
- Filtration and backflow protection on the supply
Typical buildings
Standards and good practice
Irrigation is governed less by building codes than by good design practice and the water supplier’s rules. Projects commonly call for:
- BS EN 1717
- Protection of drinking water against pollution by backflow, where irrigation connects to a potable supply
- Manufacturer data
- Spacing, pressure and flow limits published for the sprinklers, emitters and valves used
- Supply rules
- The water utility’s connection conditions, or the abstraction permit for a borehole source
- Landscape specification
- The landscape architect’s planting plan and watering requirements
The governing requirements are set by the project specification, the landscape consultant and the water authority; we design and install to them.
How we work
A clear process, start to finish
Brief and site visit
We review your drawings, specification or bill of quantities and, where needed, visit the site to understand the building and how it will be used.
Design and proposal
We size the system, select equipment to the specification and give you a clear, itemised quotation.
Approvals and procurement
Shop drawings and material submittals go to the consultant for approval before materials are ordered.
Installation
Our own crews install the works, coordinated with the main contractor and the other trades on site.
Testing and commissioning
Every system is tested and commissioned, with results recorded and witnessed by the client or consultant.
Handover and aftercare
As-built drawings, operation and maintenance information and training for your team, followed by maintenance when you need it.

FAQ
Automatic Irrigation Systems: common questions
Yes. We size the pump and pipework to the source, and add filtration where the water carries sand or silt that would block sprinklers and drip emitters.
A well-designed system puts water where it is needed, at the right time of day and in the right amount for each zone. Rain or moisture sensors stop it running when watering is not needed.
Yes. We plan routes that avoid established trees and existing services, and reinstate lawns and beds after the pipework is laid.
Yes. We check coverage, repair leaks, valves and heads, and reprogramme controllers so the system waters evenly again.
