Why is the water so hard in Littlehampton?

If you live in Littlehampton and have noticed lots of limescale build up around your taps and appliances, that’s because the water is very much on the hard side! It didn’t start off that way when it fell as rain but, like many parts of the south of England, the water flows down from the chalky soil of the Downs, which turns it hard.

With a water hardness reading of anywhere between 240 and 280 ppm (parts per million), Littlehampton’s supply registers towards the top end of the scale. Anything above 200 ppm is deemed hard. So, it’s not surprising that many local residents choose to have a water softener installed, to provide much needed respite!

The seaside resort town of Littlehampton, with its pleasure harbour, is the largest populated town (55,000 residents) in the Arun District, situated on the mouth of the River Arun, 19 miles west of Brighton and 10 miles east of Chichester. Bognor Regis and Worthing lie either side along the coast.


In the 18th century, Littlehampton progressed from being a fishing community into a popular to a holiday destination, with the likes of the poet Lord Byron and artist John Constable known to have spent time there. By the 1920s, it was known as The Children’s Paradise.

In 1967, the town attracted attention by becoming the base for the first ever Blue Peter lifeboat.
