The Adeje water route event will be in Spanish with simultaneous translation into English

The Adeje councillor for tourism, Ermitas Moreira García, announced details of this Sunday’s Water Route, which will see performances in costume along the way, underlying the important role water has played in the evolution of the borough. The route is scheduled to coincide with World Water day (celebrated this week) and the performances will be by the Adeje Municipal Folklore School. It will be in Spanish with simultaneous translation into English

The councillor explained that “the riches of our heritage are very relevant, not just for residents, but also for those who visit, looking for new experiences. The re-evaluation of our history, a history which unites us, is a fundamental task in the building of a viable tourist destination. For that reason the water route is an excellent way to remember the importance of this natural resource, looking at is use and relevance from an historic perspective”.

The route will start at 11am, from the entrance to the Barranco del infierno, following on to the Arriba mill, the Tres Chorros fountain, the Old Mill, orchards, the Fort House, the Santa Úrsula Church, the Calle Grande, Calle Sindical, and onto the plaza at Cruz del Llano. An addition this year will be a scene showing the lives of the Marquises of Adeje.

Anyone who would like to take part can do so, and participation is free. You will need to arrive on time to the starting point at the Barranco del Infierno.


Adeje has always been considered a privileged location, in the past as it is today. The borough had the biggest number of springs along the coast – two higher up where the Erques ravine is, three in the area known as El Aserradero, two in the Barranco del Infierno, one at the top of the Barranco del Agua, another at the foot of the Roque de los Brezos and another beside the Roque de Imoque. The borough was a settlement area for a large group of Guanches, (the local aborigine inhabitants). This was also the home of the ‘Gran Tinerfe’ one of the most important chieftains in Tenerife in his time, whose statue today is at the entrance to the town of Adeje.

After the conquest of the island, in the south, and particularly in Adeje, water played a very important role as a local resource, with the Rio de Adeje (the Adeje river) flowing from the Barranco del Infierno down to the sea.

Adeje’s water gets top marks



According to the latest report from the Municipal Laboratory, the unit that is charged with collecting and sending regular data to the national body in charge of drinking water, “in 2015 there was a 100% positive result on all tap water samples tested in the Adeje area “ adding that the water is fit for human consumption. The laboratory is an arm of the Council’s health protection and quality of life department under councillor Amada Trujillo Bencomo.

The councillor explained that “improvements in the water supply coupled with investment in installations and infrastructure by the Council as well as insisting on the most rigorous testing controls carried out by the Aqualia-Entemanser company have all contributed to the positive evolution of the quality of drinking water in the borough.” The controls check water, colour, smell, taste, turbidity, conductivity, ph levels, ammonia, presence of bacteria, e coli, minerals, etc.

Adeje is one of the Canarian boroughs that carry out continuous controls of tap water. During 2105 there were almost 230 samples testing 44.75% samples from private homes and 55.2% from public buildings and within the commercial sector. The report also detailed the different public and privately managed water supply systems in the borough and changes introduced in recent years. Just over two thirds of the population of Adeje receive their water supply from a combination of water supplied from natural water galleries, reservoirs, and desalination plants and the other third from galleries and reservoirs only.

The councillor also stated, “The quality control of tap water for consumers is a priority for Adeje Council, meeting, as they do, all the norms and conditions and directives laid down at regional and national level to guarantee that water supplied to the consumer is healthy and clean. The excellent results are the fruit on ongoing investment on the part of the Adeje council as well as the company charged with supply both in existing installations and new ones such as the desalination plant in La Caleta”

This is the eighth report prepared by the Laboratory since its establishment in 2007 since which time the department has been granted a certificate guaranteeing supply conforms under ISO 9001:2008 norms. The Laboratory is regulated by rules laid down by the regional government’s department of health.

In 2014 100 % of all water samples tested were approved for human consumption

The Adeje Municipal Laboratory, under the department of health locally, has released data alongside its annual report which emphasises the “important improvements in the quality of water in Adeje”. Adeje continues to be borough with the second highest number of tap water controls in the Canaries, just behind Las Palmas de Gran Canaria.

The report underlines that during the whole of 2014 not one single result showed that the water wasn’t meeting all the required standards. Altogether the laboratory carried out 236 analysis of consumer tap water. “Control of the quality of tap waters is a top priority for the Adeje council, as is meeting all the require standards and following the national and regional laws designed to guarantee that water from the taps is apt for consumption, healthy and clean for the people”, the report states. The excellent data is also a direct result of on-going inversion in the waterworks by the council and the water provision service, Aqualia Entemanser, in both the allocation of new installations such as the desalination plant in La Caleta.

The municipal laboratory continues to abide by the Royal Decree 140/2003 which regulates levels of smell, colour, turbidity, conductivity, ph., ammonia, coliform bacteria, e.coli, copper, nickel, iron, chlorine, etc. As well as these indicators, the lab also carries out tests on the water in different channels to determine levels of boron and chlorides.

Regarding conductivity the tests show a marked improvement since 2008 with levels now below 1000 s/cm, which is considered to be a medium-high level of mineralisation. In Adeje in 2014 the level of water in home taps was, on average, at 250-700 s/cm.

Just over half of the samples tested were taken from private homes and the rest from installations and public buildings or commercial centres. Currently Adeje has 30 supply points, the most concentrated in the Las Torres zone supplying over 26,000 homes. Over three quarters of Adeje’s residents use water from a combination of sources – dams, water galleries, and desalination plants, with the remainder getting their water exclusively from dams and water galleries. And on-going improvements should see a series of improvements to current installations alongside the Aqualia-Entemanser company to homogenise water quality throughout the borough.

Fit to drink

Adeje water the most tested in the last 10 years

Adeje carries out more health controls on tap water than any other borough in the Canaries. The most recent studies meet all the European directives regarding tap water and show that the water is perfectly safe to drink.

According to the Adeje councillor for sanitation, José María Álvarez Acosta, the tap water in the borough can be classed as ‘good or very good’ depending on the area. The data published is part of a study carried out by the Adeje municipal laboratory and the Aqualia Centro company. The conclusions were that Adeje’s water is now apt for human consumption.

Álvarez Acosta confirmed that “the proper quality control of water in homes is our main objective here in the Adeje council. We will continue regular analysis and continue to meet all the European standards as well as national and regional norms. In that way we can guarantee that our water is clean, healthy and apt for consumption”. He confirmed too that “Adeje was the second most tested zone in the Canaries in 2013 and the most tested over the longer period of 2004 – 2013. The most recent date comes from the sixth control report carried out in Adeje”, the councillor continued.

Adeje uses water from two desalinisation plants, one in La Caleta and the other, shared with Arona, in Las Américas. Councillor Álvarez said that recent work had also seen the water pipe network improved to guarantee the quality of water arriving into Adeje’s homes.

The borough’s laboratory, which meets all of the EU standards, was opened in Adeje in 2007, has dedicated a number of studies to improve the quality of water in Adeje. “Today we can stand over the claim that we are a leading borough in the treatment, desalinisation, and quality of infrastructure dedicated to water consumption”, he said. Water is tested using a number of parameters, including smell, taste, colour, conductivity, pH and turbidity levels, ammonia, bacterial content, presence of e coli, presence of minerals such as copper, iron, nickel, residual chlorine and boron.


The laboratory uses a national programme for control and analysis of tap water, in place since 2007. The controls were carried out in homes and public and private installations using the public water system. 65 per cent of the residential population of Adeje receive water sourced from dams, the island’s natural water galleries and from the desalinisation plants, with the rest of the homes in receipt of water sources exclusively from dams and galleries.


Water, Water Everywhere…

water plant works

Over 6.5 million Euros has been invested in the sea water desalination and purification plant in Las Américas meaning a significant increase in the amount of water processed daily.

The investment was part of a joint project by the Adeje and Arona councils and the Tenerife Cabildo as part of the regional Canarian State Covenant. At a press conference to announce details of the improvements Adeje’s Gonzalo Delgado Díaz and Antonio Sosa for Arona joined Tenerife Cabildo president Carlos Alonso and the minister for water Jesús Morales in the installation beside the national police station in Las Américas.

Gonzalo Delgado told press “81% of the water consumed in Adeje is desalinated, and of high quality. We are planning to reach 91 % of the population within a year with the improvement works that are being undertaken and an upgrade to the drinking water network financed by the Adeje council.
“At the moment the Adeje-Arona desalination plant supplies our borough with about 5 million cubic metres of water annually, which, added to the 3 million cubic metres produced by the plant in La Caleta, gives the 81% coverage I mentioned. We can say that, unquestionably, Adeje has the best quality water in the island.”

The Tenerife president and the minister for water commented on the scheduled works that would mean important energy savings and improvements in the quality and quantity of water processed in the Adeje-Arona plant.

In the last year, with the investment, the production of desalinated water increased to a daily average of 22,991m3, with a significant increase of the last 12 month period. The plant has been in operation since 1998 and has a current daily capacity of 30,000 m3, up from 10,000m3 when it was first opened. It serves Adeje and Arona, mainly in the tourist zones and along the coast.

The recent improvements to the plant included:
• Upgrades in the energy efficiency of the desalination process
• Remineralisation via filters
• Reform of the pump station in Parque de la Reina (linked to the Adeje-Arona unit)
• Introduction of a mixed rack conduction system dealing with desalination, regeneration and sanitation of sea water.

Regarding the operation of sanitation and purification energy saving pumps are being installed using variable-frequency drive (VFD).
Further investments are also planned in the pump station in Parque de la Reina which will facilitate water conduction up to Llano del Camello and Las Chafiras and the coastal areas of San Miguel de Abona.

Top Water Quality

Adeje has been working for a number of years to improve the quality of water in the borough, and the water that reaches our taps comes from both the island’s natural water galleries and the desalination plants here in the area. The council has also been working with the locally based company charged with improving the quality of the water and today, says the councillor for works in Adeje Gonzalo Delgado, Adejeros can count on top quality water.
The ongoing system of vigilance led to the detection of boron in a number of isolated cases last month, all of which have been resolved. In fact, according to regional comparisons, Adeje carries out the most controls of tap water of any of the Canarian boroughs, checking a number of factors including smell, taste, colour, ph balance, bacterial presence, fluoride, nitrates, etc. With the opening of the desalination plant in La Caleta in 2011, in addition to the Adeje-Arona plant already in operation, the quality improved further. In 2012, says Delgado, there were 320 separate inspections carried out, 57.26 per cent of them in private homes, and 42.7 per cent in public and commercial spaces, and according to the results published by the National Water Consumption Information System all the water in Adeje is apt for consumption.
The Municipal Laboratory also carried out controlled studies on the water quality in the borough’s beaches, important for maintaining blue flag status, as well as for consumers, with highly satisfactory results, with the sea water by Adeje beaches of “excellent quality”, so good news for bathers.
