Watering prohibition

Watering prohibition in the municipalities of Södertälje and Nykvarn

Groundwater levels are unusually low in many parts of Sweden at present. The situation in the municipalities of Södertälje and Nykvarn is so serious that a watering prohibition is being introduced. The prohibition applies to all those with a municipal water supply, including companies and other organisations, from 2 May 2017 until further notice.
Municipal drinking water supplies must principally be used for food, drink and hygiene. By complying with the watering ban you will be helping to save groundwater so that there is enough for hospitals, nursery schools, residences for the elderly and everyday home life.

What has happened?

Telge Nät monitors and measures the levels of groundwater regularly. Normally the reservoir of groundwater is built up over the winter and can be used in the summer. But the position before summer starts this year has deteriorated. Long dry periods have meant that groundwater levels have not recovered as they normally do. That is why we now face the challenge of maintaining a sufficient water supply right through the summer.

Exceptions for industry

Companies that must use the public water supply to operate are exempted from the prohibition but are asked to be extra careful in using water. This applies to companies that use high-pressure cleaning, water to cast concrete, bind dust on building sites or water plants for sale, commercial gardens and plant nurseries for example.

The watering prohibition means that:

  • You cannot fill your pool with municipal drinking water. This also applies to inflatable pools, hot tubs and spa baths. A sunken pool can only be filed to a level where there is no risk of its framework collapsing, but no more. Visit our public swimming pools and bathing lakes instead.
  • You cannot use a hose or sprinkler to water your garden. Collect rainwater and use it for watering instead.
  • You cannot wash your car with a hose or high-pressure cleaner. Instead, you can use authorised car washes and self-service points that re-use the water.
  • You cannot use high-pressure cleaners to clean house facades, balconies or similar.

Tips for saving water:

  • Before you use water, think about whether you really need to right now.
  • Change to water saving showers­ and taps.
  • Don’t let taps run unnecessarily. Every minute the tap runs means about 6 litres of water.
  • Don’t fill up the bath tub. Shower quickly and turn the water off while you apply soap or shampoo.
  • Don’t start dishwashers­ or washing machines until thy are completely full. A dswasher uses 15 litres of water and a washing machine uses 50 litres.
  • Don’t wash up under running water. Use the sink or a bowl. You ca use left over washing up water to clean off sticky containers.
  • Instead of running the tap for a long time to get cold water, why not fill up a jug and put it in the fridge?.
  • Use the small flush button if you have only peed. Why not fit a water saving toilet? Good for both the environment and your wallet.
  • Heat water in a kettle or saucepan if you need to run the tap for a long time to get hot water.

Fix dripping taps and running toilets

  • A dripping tap can lose up to 20,000 litres of water a year. That’s more than 130 full bath tubs. In one day it’s about 55 litres.
  • In one year a leaking toilet can use 400,000 litres of water, or about 2,700 bath tubs. In one day that’s about 1,000 litres.

Questions and answers

Where does the municipal water come from?

A fifth of the municipal drinking water in Södertälje and Nykvarn consists of the natural groundwater that comes from rain and snow. The rest is pumped up from the Mälaren. It is naturally filtered via a boulder ridge before being inspected, purified and delivered to your tap.

How long will the watering prohibition last?

The watering prohibition is in force from 2 May until further notice. According to our forecasts we believe it will be in force throughout the summer.

Could the water run out?

No. Normally we have a good over-capacity in the groundwater reservoir. But when the levels fall, our normal safety margin becomes too small. That is not happening suddenly now, it takes awhile for the water level to fall. We are using this time to make preparations and inform the public, for example, as we are doing now. If everyone helps to save water and complies with the watering ban, we will gradually get back to normal water levels.

What is Telge Nät doing?

Telge Nät is working to find causes and solutions for why water consumption increases and water levels are falling. Planing work must be adapted to needs so as to ensure long-term access to water. This means that the network of pipes needs to be checked, we need to check for any leaks, groundwater paths and reservoirs need to be investigated. Work is also going n to communicate with households, companies and industry so as to minimise water consumption at all stages.

What can you do if you have a pool?

The watering ban applies to all pools, including inflatable pools, hot tubs and spa baths. A sunken pool can only be filed to a level where there is no risk of its framework collapsing, but no more. If you are uncertain, check the information you received when the pool was installed or contact your pool dealer. The pool must not be filed just so that you can swim in it.
