10 solutions to conserve water


BNP Paribas Asset Management has joined forces with the GoodPlanet Foundation to produce this guide that shares useful information and good habits that everyone can use to conserve water, a precious resource, which is both abundant and scarce.

1) Let’s save water!

There is an array of solutions to help consumers conserve water. For example, a bath requires on average 150 to 200 litres of water – three times more than a quick shower. Contrary to popular belief, however, a 10-minute shower uses just as much water as a bath. Let’s take special care to reduce our water consumption as far as possible through small everyday actions.

2) Let’s equip our homes!

Various types of equipment have been developed to reduce our water consumption: water-saving aerator taps, efficient shower heads, and so on: these purchases generally become cost-effective within less than one year. By way of example, the installation of a dual-flush system (3 or 6 litres) saves up to 10,000 litres per year and per home, at a price of only EUR 30.

3) Let’s find those water leaks!

There are many tips for identifying water leaks and reducing wastage. A good solution for identifying a possible leak, for example, is to check the water meter one morning when nobody is home, and check it again in the evening upon your return to see whether it has changed.

4) Let’s save water in the garden!

We can all implement effective solutions to optimise both the irrigation of farmlands and the watering of our own vegetable gardens. For example, simple installations such as a tub at the end of a gutter will suffice to meet most of our everyday water needs and thereby prevent the use of drinkable water for garden irrigation.

5) Let’s choose recycled paper!

Don’t forget: the best waste is no waste. First and foremost, we should keep our paper consumption to a minimum and only print documents when really necessary. In addition, always choose recycled paper, which has a much lower environmental impact.

6) Let’s choose eco-labelled hygiene and cleaning products!

Choose eco-labelled products to reduce the environmental impact of our cleaning products: they limit the use of hazardous substances and foster the use of biodegradable materials, which are less harmful to aquatic ecosystems. Their performance has been tested to guarantee they are at least as effective as other products on the market.

7) Let’s sort our waste!

Today, waste sorting has become essential to the recycling process and prevents waste from ending up at the bottom of the ocean. For example, 67 plastic water bottles can be recycled to manufacture a two-person blanket.

8) Let’s drink tap water!

The choice between bottled and tap water is an easy one. Especially since there are many solutions nowadays to customise tap water to suit your tastes, such as filter jugs and carbonation machines!

9) Let’s adopt a water-efficient diet!

By changing our dietary habits, we can significantly reduce our impact. For example reducing our consumption of meat (red meat in particular) is a highly effective solution for conserving the planet’s water on a daily basis! Introducing one vegetarian meal a week saves more than 35,000 litres of virtual water every month for a family of four.

10) Let’s buy organic products!

Many more sustainable farming methods are being developed and will help limit the pollution of our waterways. Organic farming is the most widespread one, and can be recognised by way of labelling. Let’s use organic products grown without synthetic chemicals to limit the pollution of our waterways.
