Noordwijk has a stretch of 14 kilometres of sandy North Sea beaches. The sea is clean and Noordwijk has been awarded a Blue Flag label, indicating bathing water quality, for years. Visitors can walk over the beach beyond Noordwijk to Zandvoort or Katwijk.

        

All water within the Noordwijk Municipality is treated after use. Dunea and Waternet are the companies responsible for the supply of drinking water in Noordwijk and its surroundings. The process of drink water production starts by infiltration of river water at great depths in the dunes where it will stay a period of approximately two months. After this period the water is pumped to the surface and goes through an additional filter process. This technique has the advantages that it is very sustainable and gives the drinking water a natural taste, in contrast to chemical cleaning.    

As a rule there are no long traffic jams to get to the beaches of Noordwijk, parking space is available close to the beach and there are safe crossings from the boulevards to the beaches. However, traffic jams can occur on warm summer days so it is best to go by public transport or by bike to Noordwijk on those days. 

Where there is tourism there is waste, for a clean environment a proper waste management plan is important. Noordwijk takes many precautions to keep its municipality and beach clean. For example there are easy recognizable garbage cans on the beaches, on the boulevards and in the rest of the town.

In the residential areas the waste is collected separately and processed elsewhere. The frequency of beach cleaning is adapted to the amount of visitors in the different seasons, resulting in a very clean beach area.

Noordwijk is a coastal town in a low-lying country. This means that climate change is a very important issue. Climate change means sea level rise and increased rainfall. Noordwijk has adapted to those new challenges by increasing sewage water buffering and filtering capacity and by increasing its sea defence system.

The new sea defence system was finished early 2008 and looks state of the art! Additionally the municipality itself promotes the reduction of energy use itself.
