The EU — The Polluter Pays
The EU Water Framework Directive
In 2000, the European Union issued its Water Framework Directive (WFD). This directive called for a more holistic approach to how water quality and levels of water pollution are assessed. It placed the focus on river basins, because this is where most cities, towns, industries and agricultural activities are centred, and because rivers are a primary source of water for domestic and other uses. (It also takes other water systems into account.) The WFD directed that, in future, water quality and water pollution must be assessed, not simply by water testing against a given standard, but by examining the impact of human activity upon the ecosystem of a river basin or water system as a whole. The impact on animal and plant life, changes in water chemistry and in hydromorphology, will determine whether a water system is judged to have good quality water.
This move raises the bar for water quality testing, challenging any temptation to set standards that might be more easily met, but which would have an environmental cost. Every EU country must achieve a ‘good’ status in all of their significant river basins and water systems by 2015. To see where Ireland stands in relation to these standards, see our blog post Water Quality in Ireland.
The Polluter Pays
Another significant, related directive of the WFD is that the polluter pays principle should inform not only policy around major pollution incidents, but water supply and waste water charges as well. This has far-reaching implications. The polluter pays principle says that industries, businesses and agriculture must pay for the cost of water supplies and also for any waste water treatment of the run-off from their plants, premises or farms. All such costs associated with maintaining water quality are to be built into users’ water charges.
However, almost every human use of water pollutes it. Domestic washing, cleaning, toilet and sewer systems, all add dirt, waste and chemicals to the water we use. And so the polluter pays principle applies to domestic water usage too. Under the WFD, domestic users will pay for the water they use and also for the post-use treatment of that water. This is already the case in the UK, where domestic users can pay as much for the quantity of waste water they allow flow into the sewers as for the water they draw from the water supply in the first place. (Waste water is also metered). The challenge for households will be to minimise water use and to minimise their pollution of that water.
Water Charges
The WFD does not allow governments to profit from water charges, but the directive recommends two policies which will push water charges upward. First, governments are directed to price water at a sufficiently high level so as that users will be motivated to reduce their water usage. (Higher water charges, together with more water-efficient technologies, have been an important factor in falling domestic water usage in many European countries.) Second, governments are encouraged to take a long-term economic view. In principle, this means that prices might fall due to anticipated falling costs of supplying water in the future. In practice, it is more likely to mean that governments will factor into current prices anticipated future increases in the cost of maintaining an adequate water supply due to higher demand, increased industrial activity, the need to replace or upgrade infrastructure, or more exacting environmental standards, etc.
The Challenges Ahead
In 2007, the Irish Government enacted the Water Services Act, which goes some way toward meeting the requirements of the EU directive, though many of the Act’s provisions remain to be fully implemented. As they are implemented, the challenge for households and businesses will be
- to reduce water use through elimination of water wastage
- to reduce water use through water-efficient practices and equipment
- to minimise contamination of water used
- to re-use grey-water appropriately
- to collect and use rainwater appropriately
GreenValet’s waterless car cleaning & valeting products and domestic cleaning products offer households significant ways of reducing their water usage.
For car valeting businesses and the auto industry, GreenValet’s Complete Car Cleaning & Valeting Solution offers a 100% non-toxic waterless system and a water-based system, which will reduce water use significantly and which is 100% non-toxic.

Our Domestic Water Usage
A recent survey revealed that 91% of Irish people have no idea how much water they use. This has to change, if we are to conserve water and use it effectively. And with the introduction of domestic water metering in the near future, we need to educate ourselves, if we are to keep water bills under control.
Our Water Usage
So how much water do we use? On average, each Irish person uses approximately 150 litres of water per day. The average household (of 3 persons) uses about 450 litres per day. This is about the same level of usage as in the UK, but higher than most European countries with similar climate and economies. However, in these other countries water usage is falling, whereas, in Ireland, it continues to increase. In 1997, it was estimated we used between 131 and 139 litres per person per day, by 2006 that figure had risen to 148 litres, and our usage has continued to increase.
What we use water for
A large proportion of our water usage is on showering/bathing (38%) and toilet flushing (27%). It might surprise you to hear that drinking water and cooking account for only 3% each. On average 12% of water is used on external uses like car washing and garden watering. Note, however, that if you regularly water your lawn or wash your car with a hose, they will form a far larger proportion of your water usage. The percentage is low because many people do neither.
Typical usage for different household items:
| Bath | 80 litres |
| 5 minute Shower | 35–45 litres |
| Power Shower (less than 5 mins.) | 80–125 litres |
| Toilet Flush (older model) | 9 litres |
| Toilet Flush (modern model) | 6 litres |
| Brushing teeth with tap running | 6 litres |
| Brushing teeth with tap off | 1 litres |
| Washing Machine (modern model) | 45 litres |
| Washing Machine (older model) | 65 litres |
| Dishwasher | 20 litres |
| Hosepipe | 9 litres per minute |
| Washing car with hose pipe | 300–450 litres |
| Washing car with bucket (4 bucketfuls) | 30 litres |
A Two-Fold Challenge
The challenge is two-fold. We need to cut out unnecessary water wastage and we need to find more efficient ways of using water.
A good example of waste is that 40% of Irish people use over 170 litres per day on showering, flushing toilets and brushing teeth alone. 61% take 10 minute showers (or longer), with 67% letting water run for 1 to 2 minutes before getting into the shower. Note that a typical shower might use 9 litres per minute so that a 10 minute shower with the water running for 2 minutes beforehand could use 108 litres of water. Half of us use this much water on showering each day.
Again, using 300–450 litres of water washing our cars is a massive waste of water when effective waterless car washing products are available.
Newer more water-efficient equipment will use reduced amounts of water. But there are many things we can do that cost little or nothing to implement. See our Top 10 Water Saving Tips.
