Irrigation in the northeast of Lanzarote: what to prepare for commissioning
An irrigation desalination plant is not ready for handover simply because it produces water. The engineering team, the contractor and the operator receiving it need to agree on the checks, who will handle incidents, and the documentation and spare parts to be supplied with the installation. Preparing this transition helps define enquiries about supply and technical support.
The update on the Tinajo and Teguise irrigation project provides a practical context for reviewing these needs. This guidance can help both collective infrastructure operators and farms preparing to commission irrigation desalination plants in Lanzarote.
Key points for preparing handover
- The announced schedule is a forecast; the reception depends on completing work and procedures.
- Tests must follow the project, contract and equipment manuals.
- The necessary quality is defined according to agricultural use, cultivation, and soil conditions.
- Enquiries about local support should specify the scope: equipment, location, tasks and timescales.
What has changed in the project of Tinajo and Teguise
The Cabildo’s update of 6 October 2026, reported by Crónicas de Lanzarote, gives December 2026 as the planned date for commissioning and handover to users of the northeast irrigation modernisation project. The scheme combines reverse osmosis desalination, pumping, wind energy, storage and a network with remote metering and control.
The project involves €24.4 million and is intended to serve 300 hectares and 667 irrigation users. The meeting with SEIASA addressed outstanding works and the handover and acceptance of the infrastructure by the Island Water Council. The final financial account was approved on 29 September.
This is an update on a project under construction, not an open grant scheme or the announcement of a new tender. The schedule remains subject to completion of the works and administrative procedures. There is no recorded involvement of HidroSoluciones Canarias in this project.
Clarify responsibilities before handover
Coordination starts with identifying who performs and validates each task. The contractor may need to complete connections; the integrator, check signals and automation; and the operations manager, receive instructions and records. A local support enquiry should specify the work requested and the tasks already covered by existing contracts.
Supplier support does not replace formal acceptance of the works or approval by the supervising engineering team. A list of outstanding items, each with a responsible party and a completion criterion, helps avoid quotations that duplicate tasks or omit necessary work.
What to check and document
The test programme should be agreed with the engineering team and follow the project and equipment manuals. This table links practical issues to the information needed for an enquiry; it does not replace the contractual acceptance protocol.
| Aspect | Information that is worth gathering | Requirement these details help define |
|---|---|---|
| Flow rate and delivery point | Production and pressure expected, measurement point and test conditions. | Check that the plant, pumping and distribution are assessed within the same scope. |
| Water quality | Feed water and delivered water analyses, date, units and intended use. | Reviewing treatment goals and agricultural needs. |
| Connections and control | Hydraulic and electrical schematics, inventory of signals and documentation of the integrator. | Specify checks or integration without guessing interfaces. |
| Initial operation | Manuals, agreed training, incident log and responsible contacts. | Define assistance, follow-up and maintenance. |
| Spare parts and consumables | Models, technical references, quantities and storage conditions. | Request compatible components and compare offers. |
If sensor data or operating records are missing, see the article on what to measure before investing in instrumentation for a desalination plant. Here, the aim is to prepare the transition to operation, rather than develop another catalogue of measurements.
From the water produced to the water needed by the crop
Conductivity indicates salinity, but is not enough on its own to determine suitability for irrigation. The FAO relates irrigation water quality to salinity, infiltration and the toxicity of ions such as sodium, chloride and boron. Interpretation depends on the crop, soil and management; these guidelines should not become a universal limit for every plot.
Agree which analyses are needed for the agronomic assessment and where samples will be taken: at the treatment outlet, in storage or at the delivery point. A technical enquiry should distinguish these locations. Minimising conductivity cannot always be assumed to be the right objective, and blending or conditioning should not be recommended without data.
Filtration at the irrigation headworks serves a different purpose from salt separation by reverse osmosis. Enquiries about filters or distribution components need to specify feed water quality, irrigation flow rate and installed system requirements; water may pass through storage and pipelines before reaching the crops.
Prepare consumables and initial maintenance
Before ordering an initial batch, it is preferable to have the final inventory of equipment available. Membranes, cartridges, gaskets, and dosing or control components should be selected for compatibility and function. The size of a connection or an isolated photograph does not necessarily identify a replacement part.
The offer should separate the supply, installation, assistance, and included materials. It should also clarify coordination with existing warranties and who performs each task. Maintenance quantities and frequencies are determined with the manufacturer and based on actual operating conditions, without promising availability or a delivery date that has not yet been confirmed.
The page on maintenance and spare parts for desalination plants helps frame an enquiry about installation components and requirements. For financing an agricultural investment, a separate article covers grants for irrigation water in the Canary Islands; this project announcement does not itself open a grant scheme.
Information for technical support enquiries in Lanzarote
Companies based in mainland Spain carrying out works in the Canary Islands and local operators can make a more precise enquiry by providing:
- Island, municipality, location and coordination contact.
- Agricultural use, expected flow rate and available water analyses.
- Equipment list, drawings and connection points.
- Specific task: supply, component testing, installation, commissioning assistance or maintenance.
- Planned schedule, access conditions and outstanding handover items.
HidroSoluciones Canarias can assess a query related to water treatment, spare parts, and local technical support. The scope must be confirmed for each installation. The potential needs outlined in this publication do not imply a contractual relationship with the Tinajo and Teguise project.

Preparing to take over an irrigation water installation?
Send us the location in Lanzarote or another island, the flow rate, the equipment and the tasks you need to solve. With that information we can assess a request for spare parts, supplies or technical collaboration with a defined scope.
