How hard is the water in Chichester?

Water hardness reading in Chichester:
280-300 ppm (very hard)

Why is the water in Chichester ‘very hard’?

Like so many parts of the south of England, the soil in and around Chichester is extremely chalky. This means that when it rains, the water turns exceptionally hard, with the readings being between 280 and 300 ppm (parts per million).

The difference between the two readings is to allow for varying amounts of rainfall. The more rainfall that gets into the bedrock, the harder the water becomes. During drier periods, the hardness level will tend to drop to the lower level.

Water is always in close proximity to the city of Chichester (population 26,795 at the last census). Located on the River Lavant, which flows through parts of the city in underground culverts, historic Chichester is the only city in West Sussex and the county’s administrative headquarters. The cathedral has a distinctive 266 ft spire which had to be rebuilt in 1861 after collapsing in on itself.

Chichester Festival Theatre is one of the country’s most famous regional touring theatres; its first artistic director was Sir Laurence Olivier. Notable “locals” from the city include the Olympic middle distance runner and former MP, Christopher Chataway and Tim Peake, the first British astronaut to visit the International Space Station.
Nearby, Chichester Harbour is a 3,733.5-hectare biological and geological Site of Special Scientific Interest, featuring Bosham, frequented by the yachting fraternity and one of the most photographed villages in south-east England.

Excellent customer service. Thank you so much.

Scott recently supplied and installed an EcoWater Evolution Refiner Power system in our home. We are happy with the improvement in our water quality. The overall experience has been very good. Scott visited to advise us on the most suitable machine for our household and also liaised with our plumber to ensure the correct connections to and from the system. Communications throughout were good – we knew what to expect and when. The installation went pretty smoothly, taking a little longer than expected because, on checking the initial set-up, Scott found a small problem causing a slight leak but he made sure that that was resolved to his own satisfaction before he left. After-sales support seems strong too – Scott has stayed in touch, however we have not needed anything to date. Recommended!
