What is being applied for at the Casa Cabildo?
The Cabildo Insular de Lanzarote y La Graciosa is applying for water-law authorisation to use abstraction and discharge boreholes. These boreholes are connected to a low-enthalpy geothermal system intended to make the cooling system of the administrative building more efficient.
The installation is located on Avenida Fred Olsen, s/n, in Arrecife. According to the application, the maximum discharge volume is 493.15 cubic metres per day. No easement or expropriation is being requested, according to the notice.
Low-enthalpy geothermal energy uses water or the ground as a heat source or heat sink. It is used for building climate control, not for electricity generation.
How does the public consultation work?
The notice provides for a public inspection period of 30 days. The BOC gives 23 September 2026 as the date of the underlying notice. However, the published extract does not expressly confirm from which day the period is calculated.
The full procedure and the submission of any objections are possible at the Consejo Insular de Aguas de Lanzarote. The address is Avenida Fred Olsen, s/n, 35500 Arrecife.
The procedure is based on Article 17 of the Reglamento de Control de Vertidos para la Protección del Dominio Público Hidráulico. Publication took place in the BOC, issue no. 199 of Monday, 5 October 2026, as notice no. 3435.
What does this mean for residents and visitors?
The publication mentions no new water, electricity or admission prices and no fees for residents, expats or visitors. No closure or changed opening hours are announced for the Casa Cabildo.
According to the published content, residents, foreign residents and tourists do not need to submit an application. They may only submit comments as part of the public consultation, provided the full procedure allows for this.
The title mentions Lanzarote and La Graciosa institutionally. However, according to the BOC, the specific project concerns the Casa Cabildo in Arrecife, not an installation on La Graciosa. A change to the water supply of La Graciosa is not confirmed.
Which technical details are known?
The notice confirms the maximum discharge volume of 493.15 cubic metres per day. However, it does not state the planned borehole capacity or the discharge volume over the course of a year. The expected energy saving is also not published.
Costs in euros, an environmental impact assessment or possible conditions are not mentioned in the notice. The applicant is the Cabildo Insular de Lanzarote y La Graciosa, and the responsible authority is the Consejo Insular de Aguas de Lanzarote.
How does the project fit into Lanzarote?
The procedure is part of a series of similar projects on Lanzarote. The Hotel Sentido Lanzarote Aequora Suites and other projects have also been published.
These publications show a growing use of the technology on Lanzarote. However, they do not allow a reliable statement about the number of installations actually approved or completed.
What remains open and what happens next?
The exact start and end of the period, the technical design, the start of construction work and final approval remain open. Possible conditions are also not published. The notice does not give a date for the decision.
The next formal step is the assessment of the comments received within the 30-day period by the responsible water authority. Only after that can a decision on approval be made.
For those affected who wish to take part, the full procedure can be inspected at the Consejo Insular de Aguas de Lanzarote in Arrecife.
