April ends with reservoirs above the average and with the highest flows since 1966
Canal de Isabel II insists on the need to continue using this natural resource efficiently, making small changes in households
• The reservoirs began May at 86.8% of their capacity, a figure that exceeds the average of the last 20 years by 7 points
• The consumption of drinking water in the Community of Madrid was 12.1% lower this month than in April of last year
The water reserves stored in the reservoirs managed by Canal de Isabel II reached the end of April at 86.8% of their total capacity, exceeding the average recorded during this period over the last 20 years by 7 points and by 6 regarding the stored volume during the same period last year, when the reservoirs were at around
80% of their maximum capacity.
Therefore, the hydrological situation in the Community of Madrid changed radically after March and April, with both months having very high rainfall compared with average historical figures. At the beginning of March, the reservoirs were at 50.6% of their capacity after an autumn and two months of winter with very little rainfall: at that time, the reservoirs were 18 points below the average values, but at the end of last month, they just about reached the average and this month the figure has exceeded these values.
Furthermore, after a start of the hydrological year with an accumulated water consumption which, in November, was 5.1% higher than the previous year, the figure recovered with the drop in water consumption during February, the notable drop took place in March, with 10.1% less water consumed and the figures for April: People in Madrid consumed 34 cubic hectometres of water, 12.1% lower than the same month in 2017. For the first time since the hydrological year began, on 1 October, the accumulated consumption in the Community of Madrid was lower than that of the previous hydrological year: specifically, 0.8% lower.
The recently ended month of April was the best since 1966 in terms of the water flow collected in the reservoirs: 191.3 cubic hectometres of water reached them, which is equivalent to around 4 and a half months’ consumption in the entire Community of Madrid. Average flows during April are 106.1 cubic hectometres. However, the water accumulated since the hydrological year began, continues to be negative, since, during the first seven months of the hydrological year, 556.0 cubic hectometres reached the reservoirs, compared with the historical average of 606.9, therefore, although the figure is improving, the amount of water is still 8% lower than the average.
It should be pointed out that the rainfall collected in the Canal de Isabel II dams in March was three times higher than the average historical figure (184 millimetres compared with the average 55.2 millimetres). The April figure is also notable: 90.1 millimetres were recorded, compared with the average figure of 62.7, i.e. 30% more water.
STRATEGIC LINE FOR GUARANTEEING SUPPLY
Despite the hydrological situation changing drastically during the last month, Canal de Isabel II, as established by line 1 of its Strategic Plan, to guarantee the water supply to the population, continues to develop information campaigns aimed at raising awareness among the population to control consumption. It is impossible to predict the amount of rainfall this spring, and therefore, in any event, it is essential to use this
natural resource as efficiently as possible.
In turn, the public company permanently develops different plans and measures to conserve the water intended for human consumption. In recent years, it has promoted the development of reclaimed water for public and industrial uses. In a year such as this one, this has enabled savings of almost 20 hm3 of drinking water (approximately 15 days of consumption in the Community of Madrid). In addition, thanks to the plans to renovate the network and regular campaigns for the detection of leaks, it has managed to reduce the volume of losses in diverted water by 70%.
Lastly, public awareness campaigns and progressive tariffs which penalise very high consumption have enabled Canal, with water rates which are 23% lower than the average in the rest of Spain, to reduce the per capita consumption by almost 30% since the last drought in 2005.
In this respect, the company highlights the small efforts that can reduce water consumption in households, such as turning of the tap when cleaning your teeth (saving 12 litres per minute); using the dishwasher and the washing machine with a full load (saving 30 litres per use) and having a shower instead of a bath (saving 150 litres per shower). All these recommendations and others can be found on the website www.sumatealretodelagua.com and on the Facebook page /elretodelagua.
Canal de Isabel II was founded more than 165 years ago to supply water to the city of Madrid. It employs more than 2500 people working daily to provide a service to more than 6 million people in the region. It is an innovative company, a leader in its sector, and internationally recognised for its management of the integrated water cycle. It operates 14 reservoirs; 78 spring tappings; 14 drinking water treatment plants; 17,434 kilometres of conveyance and distribution channels; 133 pumping stations for drinking water and 131 for waste water; 14,018 kilometres of sewage networks; 63 storm tanks; 823 kilometres of sewers and outfalls; 157 waste water treatment stations; and 512 kilometres of reclaimed water channels.
