Water shortage in Seville 2025: ecoturbino would save around 6.4 million m³ of water – Calculations & tips

Water shortage / Crisis Seville 2025 | Water Saving in Seville: 6.4 Million m³ Water Saving Potential with ecoturbino Against Water Shortage

In Seville, the vibrant capital of Andalusia, the issue of water scarcity is at the heart of public debate. With rising temperatures and irregular rainfall, the situation worsens year by year.

These trends reflect reality: The drought in Spain, particularly in Andalusia, is an urgent environmental issue affecting not only agriculture but also the daily lives of citizens.

Below, we explore the current water crisis, calculate the savings potential of our ecoturbino shower adapter, and outline how a citywide switch to 5-minute showers could optimize water consumption.

The goal is to not only inform you but also highlight simple solutions, encourage action, and provide a suggestion to the Spanish Ministry of the Environment or local authorities.

The Water Crisis in Seville: An Overview

Seville, with approximately 700,820 inhabitants in 2025 (online source), is battling persistent drought, exacerbated by climate change.

Despite heavy rainfall in March 2025, which partially replenished reservoirs, water restrictions remain in place. According to the Spanish Ministry for Ecological Transition (MITECO), water reserves in Andalusia were at about 40% capacity in early 2025 – better than the previous year but still critical.

Various experts warn of an “extreme water crisis” by 2050, as emphasized by UN reports and local media.

Current Situation in Summer 2025

Summer 2025 brought record temperatures of up to 46°C in Seville, driving water consumption to new heights.

In Andalusia, moderate to severe restrictions apply: bans on garden irrigation, limitations on car washing, and calls for household water conservation.

Greenpeace Spain highlights in its campaigns that 80% of water is used in agriculture, but urban consumption – particularly through showers and toilets – significantly contributes to the strain.

The average water consumption per person in Spain is 144 liters per day, with showers accounting for about 20%.

Impacts on Environment and Society

The drought threatens not only the drinking water supply but also the biodiversity of the Guadalquivir River and the economy. Farmers report crop failures, and tourists – Seville attracts millions of visitors – feel the restrictions.

The Ministry of the Environment estimates that Andalusia loses billions of liters of water annually, leading to higher prices and social tensions. Greenpeace, in similar reports, calls for a “green revolution” through efficient technologies to preserve reservoirs and combat climate change.

Our Solution: ecoturbino as a Cost-Effective Immediate Measure

To address the water crisis, we must rely on smart technologies. The ecoturbino is a simple shower adapter that reduces water consumption by 50% immediately after installation without compromising shower comfort.

It mixes air into the water stream, maintaining pressure while using less water. Based on our experience with customers and feedback from numerous hotel partners, it saves an individual up to €110 annually on water and energy costs.

In times of growing trends toward “ahorro de agua” (water saving), ecoturbino could be a key tool supporting Greenpeace-like initiatives: easy to install, legionella-safe, and environmentally friendly.

Why ecoturbino in Seville?

In Seville, where showering is a daily ritual – over 95% of Spaniards shower daily – our shower adapter offers tremendous potential.

Standard showerheads consume about 12-15 liters per minute. With ecoturbino (see case studies), this drops to as low as 6–7 liters per minute. Combined with a 5-minute shower duration, as calculated here, the effect is maximized.

Such measures align with the Ministry of the Environment’s recommendations for sustainable consumption and could increase engagement with environmental websites by offering practical tips.

Our Calculations: Water Savings Through ecoturbino and 5-Minute Showers
Let’s consider a realistic scenario: All 700,820 Sevillians shower only once daily for 5 minutes.

Current vs. Optimized Consumption

• Without savings measures: A standard shower (12 L/min, 5 min) consumes 60 liters per person per day. Citywide: 700,820 × 60 = 42,049,200 liters daily.
• With ecoturbino: 7 L/min × 5 min = 35 liters per shower. Citywide: 700,820 × 35 = 24,528,700 liters daily. Savings: 17,520,500 liters (17,520 m³) per day – equivalent to the volume of over 6 Olympic swimming pools!
• Annually: 17,520,500 × 365 ≈ 6.4 billion liters (6.4 million m³) water savings per year. For comparison: Seville’s average household water consumption is about 105 million cubic meters (billion liters) per year; showers account for 20%, or roughly 21 billion liters. The savings would reduce this shower-related water consumption by about 29%.

What If Everyone Switched to the ecoturbino Shower System?

With full implementation, the city’s total water consumption would decrease by about 6%, as showers are only part of the equation. For the Ministry of the Environment: A subsidy program could save millions of liters of water and relieve pressure on reservoirs.

Impact on Drinking Water Reserves

Andalusia’s reservoirs, such as the Guadalquivir Basin, currently hold about 8 billion cubic meters at 40% capacity. The annual savings of 6.4 billion liters through our shower adapters would fill approximately 77% of a reservoir – a significant contribution to resilience.

During dry periods, this could ease water restrictions and enhance supply security. Greenpeace emphasizes in similar analyses that such savings reduce pressure on groundwater and protect biodiversity. For Seville, this means less reliance on costly desalination plants and greater sustainability.

Call to Action: Together Against the Drought

The Spanish Ministry of the Environment and local authorities should consider promoting ecoturbino as a simple and cost-effective immediate measure – perhaps through pilot projects in Seville. With rising trends in water conservation, we can start a movement. Contact us for details or information – for a water-optimized future.
