Overview of Tunisia’s Water Resources
Tunisia is working hard to manage its water. It gets about 4670 hm3 of usable water each year. This water comes from rivers and underground. Knowing how Tunisia uses this water is very important.
Freshwater Availability
Water is very important in Tunisia. 57% of it comes from rivers, and the rest is from underground. This is not a lot compared to other places. So, it’s important to use water wisely in Tunisia. Also, most of the underground water has too much salt. This makes it hard to use.
Surface Water and Groundwater
Rivers, reservoirs, and rain collection give Tunisia most of its water. But keeping this water clean and plenty is hard. Things like dirt and weather changes can be problems. Groundwater is very important too. But taking too much out is a big worry. Here is a table to show this:
| Resource | Percentage of Total Freshwater | Challenges |
|---|---|---|
| Surface Water | 57% | Sedimentation, climatic variability |
| Groundwater | 43% | Over-extraction, salinity |
In short, it’s key to understand Tunisia’s water situation. This helps in making good plans for keeping water safe and enough for everyone.
Water Distribution in Tunisia
In Tunisia, SONEDE looks after water in cities and big rural places. DGGR takes care of small, rural areas. This split helps manage resources well for different people.
Tunisia is great at getting water to homes, especially in cities. Every home has a meter. This helps avoid losing water before it gets to people.
Here’s a detailed comparison of key entities involved:
| Entity | Responsibility | Area of Focus |
|---|---|---|
| SONEDE | Water supply management | Urban and large rural centres |
| DGGR | Water resource administration | Smaller rural regions |
| ONAS | Sanitation | National |
ONAS makes sure places are clean and has grown a lot recently. Working with SONEDE, they help more people get clean water and stay healthy.
Tunisia uses new technology and good management to give water to all areas. This way, everyone can have safe and clean water.
Tunisian Groundwater Sources
Groundwater is very important for Tunisia’s water. It has two kinds: renewable and non-renewable. Both have their own challenges.
Renewable Groundwater
Renewable groundwater comes from shallow places filled by rain. It’s key for farming and home use. It’s important to use this water wisely because of the dry weather.
We must watch and limit how much water we take. This helps keep the water levels stable.
Non-Renewable Groundwater
Non-renewable groundwater is deeper in the ground. These old water stores have lots of water but don’t fill up again. Taking too much water from these places can be risky.
We need to be careful with how much we use. This stops the water from running out and keeps the soil and water healthy.
| Groundwater Source Type | Characteristics | Challenges |
|---|---|---|
| Renewable Groundwater | Shallow aquifers replenished by rainfall | Sustainable management, recharge balance |
| Non-Renewable Groundwater | Deep aquifers, ancient reservoirs | Risk of over-extraction, salinity control |
Handling both types of groundwater in Tunisia well is key. This supports farming, provides clean water, and helps the economy. We must deal with each groundwater source’s problems to keep our water safe.
Role of Dams in Water Management
Dams play a key role in managing water in Tunisia. They help store water, which is vital. This way, Tunisia can handle seasonal and climatic changes better.
Major Dams and Reservoirs
Tunisia has many important dams and reservoirs. Each one is crucial for water management. Some key dams are:
- Sidi Salem Dam
- Mellegue Dam
- Kebir Dam
Besides these, Tunisia is also building more dams. This is to increase water in different areas. It’s really important, especially where water is scarce.
Challenges of Sedimentation
However, dams in Tunisia face a challenge called sedimentation. It makes the dams hold less water. So, people have to clean the dams and manage the sediment.
Dealing with sedimentation helps keep the dams working well. This means Tunisia can meet its water needs for a long time.
Tunisia Desalination Plants
Tunisia is tackling its water shortage by focusing on desalination in Tunisia. The creation of new Tunisia desalination plants is key. They are aimed particularly at coastal areas with more people and tourists.
By growing desalination in Tunisia, the country hopes to ease pressure on underground water. It aims to ensure a steady water supply all year. This balance is vital in cities.
| Region | Current Plants | Planned Plants | Total Capacity (m³/day) |
|---|---|---|---|
| Gabès | 2 | 1 | 70,000 |
| Zarzis | 1 | 2 | 50,000 |
| Djerba | 2 | 1 | 60,000 |
| Sfax | 1 | 2 | 80,000 |
Running Tunisia desalination plants faces challenges like energy use and upkeep. But new, energy-saving technology can help. Focusing on desalination in Tunisia is a smart way to secure water for the future.
