Desalination Plant Renewal Plan in the Canary Islands
Restore performance, reduce energy use and prepare your plant for reliable production. We assess what to retain, replace or upgrade in each reverse osmosis system.
For industry, hotels, agriculture, residential communities and public infrastructure.
A plant with more to offer
A sound upgrade starts with understanding the existing plant.
HidroSoluciones Canarias’ desalination plant renewal programme serves seawater and brackish-water facilities that need to restore output, control costs or reduce failures. An older plant may still have valuable components; in other cases, new technology may justify replacing an entire treatment train.
We review water quality, intake conditions, specific energy use in kWh/m³, recovery rate, membrane, pump and control-panel condition, and target water quality. These data support an upgrade matched to actual demand without assuming every component needs replacement.

Installation audit
Before proposing equipment, we measure the problem.
A drop in flow rate is not always solved by replacing membranes. It can result from pretreatment, available pressure, scaling, fouling, pumps operating outside their design point or changing demand.
- Feed, permeate and rejection analytics; pressure, flow rate and conductivity trend.
- Electricity consumption, working hours and energy per cubic metre actually produced.
- Status of pre-filters, membranes, CIP systems and chemical dosing.
- High-pressure pumping, energy recovery where applicable, instrumentation and automation.
- Space, access, hydraulic connections and the possibility of carrying out the work in phases.
What the Renove Plan can include
Technical modernisation, from pretreatment to control.
The scope is defined after inspecting the plant. These are the usual interventions in an industrial reverse osmosis desalination plant refurbishment.
Pretreatment and chemistry
Filtration, fouling control, antiscalant dosing and feedwater conditioning to protect membranes and components.
Pumps and recovery
Review of the duty point, motors and drives. In seawater, we study isobaric energy recovery devices when the design and flow rate justify it.
Reverse osmosis
Performance evaluation, membrane selection, membrane housings and stage configuration for the required quality and production.
Control and instrumentation
Flow, pressure and conductivity measurements, automation, alarms and supervision to operate with reliable data.
Cleaning and spare parts
Review of CIP, flushing, consumables availability and preventive and corrective maintenance plan.
Post-treatment and network
Remineralisation where appropriate, storage, valves and connections to the existing infrastructure.
Old desalination plant versus modernised one
Improvement is measured in the operation, not in a universal figure.
The result depends on the feed water, the scale of the plant, the existing equipment and the scope of the renovation. A useful comparison uses the same criteria before and after.
Initial situation
- Actual production and quality of the water obtained.
- kWh consumed per m³ of permeate.
- Recovery, pressures and recorded stops.
- Maintenance costs and spare parts availability.
- Automation and operation limitations.
Aim of the intervention
- Flow rate and quality adjusted to the end use.
- Lower specific energy when the project permits.
- Greater stability and early detection of deviations.
- Schedulable maintenance and accessible components.
- Investment justified against the expected lifespan.
Not all plants require an energy recovery device or achieve the same savings; solutions for seawater and brackish water are studied separately.
Energy saving simulation
A clear example, with the hypotheses in plain view.
If a plant produced 1,000 m³ daily for 350 days a year and its specific consumption fell from 4.5 to 2.5 kWh/m³, the difference would be 2,000 kWh per day of operation.
Assuming a hypothetical tariff of €0.11/kWh, the calculation would yield an annual energy cost reduction of €77,000. The investment, maintenance costs and return are analysed separately.
A thorough decision
Photovoltaics, investment and lifespan.
The hydraulic and energy improvement can be combined with other decisions, provided the site and the figures support them.
Solar photovoltaic self-consumption
We study the compatibility of solar production with the plant schedule, electrical demand, available space, and water storage strategy. Photovoltaics can reduce energy purchased from the grid, but do not by themselves modify the specific consumption of the reverse osmosis process.
Learn about modular solutionsFunding and return
We present investment and operating costs separately to assess partial replacement, comprehensive refurbishment or phased implementation. If of interest, we can look into options such as leasing or renting depending on the funder's availability and the project conditions. We do not quote grants or payback periods without verifying each case.

From the existing installation to an actionable decision.
Initial review
You tell us about production, incidents, analytics and available consumption data.
Visit and measurements
We define whether inspection, data collection or testing are required and agree on their scope.
Technical alternatives
We contrast rehabilitation, substitution and intervention phases with investment and operation.
Execution and monitoring
We plan the commissioning and maintenance according to the continuity required by the client.
Closeness and reach
Modernisation of desalination plants across all islands.
With offices in Tenerife and Gran Canaria, we coordinate projects for hotels, industry, agriculture, property owners' associations and the public sector. Logistics, access to spare parts and continuity of supply are all part of the proposition.
We work with both seawater and brackish water plants. For installations that need to preserve a large part of their equipment, we also offer maintenance and spare parts for desalination plants.
Coverage in the Canary Islands
Visits and distribution are organised according to the technical scope and location of each facility.
Frequently asked questions
What you need to know before renewing.
A serious proposal starts with operational data and measurable objectives.
Does the whole desalination plant need to be replaced?
Not necessarily. The structure, the equipment and their integration are evaluated to decide whether it is advisable to modernise components, replace a train or design a new plant.
Can a desalination plant be refurbished without interrupting the supply?
It depends on the installation. We study phases, redundancy, storage and potential bypasses to plan the work and reduce downtime, without promising absolute continuity without inspecting the plant.
What energy savings can be achieved?
The estimate is obtained by comparing consumption measured in kWh/m³, output, water quality and capital costs. The figure for a seawater plant must not be extrapolated to a brackish water one.
Does it include energy recovery ventilators and solar panels?
These are different technical options. Energy recovery can be useful in certain seawater plants; photovoltaics are assessed separately according to electricity demand, surface area and operational pattern.
Can you study leasing or renting?
Yes, depending on the amount, ownership and conditions offered by the financial institutions. Alternatives are compared without presenting financing or a subsidy as guaranteed.
