EDAR of Tías: supply and technical support in Lanzarote
The new sanitation and water regeneration projects raise a practical question for the engineering and contracting companies: how to prepare the supply of equipment, consumables and technical assistance that each part of the project needs. The expansion of the Tías wastewater treatment plant provides a concrete context for planning that work in Lanzarote.
What ACUAES has announced about Tías, Yaiza and Uga
In his Official communication of September 24, 2026, ACUAES confirms the start of the works for the Tías wastewater treatment plant and the Puerto Calero expansion project. The plant will reach 12,000 m³/day, a 50% increase in capacity, and will incorporate a new tertiary line for regeneration.
The same note announces the authorization for the tender for the Yaiza and Uga collectors and a network of regenerated water, with a budget of 6,066,313 euros, IGIC included. Its tender is pending a new addendum to the agreement. The works in Tías are scheduled to be completed in August 2028.
Started works and authorized bidding are separate entities. Before preparing an offer, it is necessary to review the current file, the tender documents and the advertisements. profile of the contractor of ACUAES. This guide does not certify an open call for tenders or a subcontracting assignment.
What engineering must define before ordering supplies
To contract water treatment in Lanzarote, it is advisable to separate the objective of the process from the commercial reference of the equipment. A request that only indicates «filter», «dosage pump» or «membrane» leaves unanswered the data that allow checking its compatibility.
The first useful document is a scope sheet: what system is to be supplied, what water it will operate on, where it will be connected, and what responsibility each company will have. If the work is part of a public contract, the proposal must respect the specifications and the material acceptance procedure of the project.
| Package to study | Data for consultation | Check that must be documented |
|---|---|---|
| Filtration and consumables | Analytics, flow, pressure and installation model. | Materials, connections, loss of charge and maintenance requirements. |
| Dosage and chemicals | Purpose of treatment, product, concentration and operating conditions. | Compatibility of materials, regulation and documentation of the product. |
| Instrumentation | Variable, measurement range, location, and necessary signals. | Integration, calibration, alarms and scheduled recordings. |
| Parts and assistance | Manufacturer, model, references, photographs and construction deadlines. | Technical equivalence, access to equipment and included tasks. |
This table is a technical preparation proposal for a consultation; it does not describe the awarded contracts from Tías nor assumes that they are available for contracting.
Filtration, disinfection and regeneration: starting from the use of water
When studying a reuse application, it is necessary to identify the intended use and the quality criteria that the water must meet. Then the existing treatment, its variability, and the control points are reviewed. It is not necessary to choose a technology solely because it is associated with another treatment plant.
Check which stage each installation needs
Ultrafiltration can be part of a wastewater treatment process for reuse. As a reference application, DuPont documents a case of tertiary treatment with UF membranes. That experience serves to understand the technology; it does not prove that it is the solution specified in Tías nor does it allow its parameters to be transferred to another water without study.
If a filtration or disinfection package is requested, the offer should explain its entry conditions, the declared performance, operational limits, cleaning and maintenance. To contextualize these alternatives, please consult our pages filtration and ultrafiltration and UV disinfection.
Connecting instrumentation and operational response
Measuring is not enough if no one has defined the response to an alarm. The documentation of Grundfos on monitoring pumping stations It shows applications of sensors, motor protection, and communication with control systems. In each installation, it must be specified what is being measured, how it is integrated, and who is involved.
When preparing a supply, request a list of signals, alarms, and acceptance tests, along with the manuals and instructions applicable to the equipment offered. The tasks and assistance capabilities are agreed upon for the specific scope.
Technical support in Lanzarote for companies that carry out projects
A company with engineering expertise on the Iberian Peninsula may need collaboration in the Canary Islands to solve a specific supply issue, review compatibility issues, or coordinate an intervention. The starting point is to share the scope and timeline, to confirm which support is feasible.
The published offer from HidroSoluciones Canarias includes the selection and supply of filters, membranes, consumables, process chemicals, dosing and instrumentation, as well as the maintenance of industrial water treatment facilities. You can consult the families and tasks on our page. Maintenance and spare parts.
For a project in Lanzarote, we will study the technical compatibility and the conditions of supply or transport. The scope, availability, deadlines and intervention are specified in the proposal; the company does not present this guide as proof of participation in the ACUAES project.
Prepare logistics and continuity from the budget
- It separates the date of manufacture, the delivery on the island, and the assembly window.
- Define who receives the material and how references and quantities will be verified.
- Identifies critical consumables and tasks that require assistance from the manufacturer.
- Requests the testing plan, training, and documentation for the operational staff.
- You agree that certain information must be kept in order to manage spare parts and incidents.
These decisions help to compare complete proposals, including what happens after the equipment is delivered.
