Wessex Water faces significant challenges in maintaining its aging pipes and water infrastructure. The company has an estimated 30,000 miles of pipes that are over 50 years old, which is a major concern for water quality and supply.
Many of these old pipes are made of materials like cast iron and asbestos cement, which are prone to leaks and corrosion. This can lead to contamination of the water supply and even affect the taste and smell of the water.
Wessex Water has been working to replace these old pipes, but it's a massive undertaking that will take decades to complete. The company has set a target to replace 70% of its cast iron pipes by 2040, which is a significant step towards improving the water infrastructure.

Water Operations
Wessex Water's operations have shown a consistent leakage figure over the past few years. In both 2011/12 and 2012/13, the company's leakage figure was 69 million litres per day.
This is a significant amount of water, and it's worth noting that it's higher than the yearly average of 73 million litres per day between 2005 and 2010.

Operations
The company's leakage figure was 69 million litres per day in both 2011/12 and 2012/13. This is a significant issue that affects the overall efficiency of their water operations.
In comparison, the yearly average leakage between 2005 and 2010 was 73 million litres per day, which is only slightly higher than the two-year average of 2011/12 and 2012/13.
This data suggests that the company made some progress in reducing their leakage between 2010 and 2012, but still has a long way to go to meet their target.

Water Infrastructure
Wessex Water's ageing pipes are more vulnerable to bursting, with the company predicting it would need to replace them at nine times its current rate to remain stable.
The number of rising main bursts has increased markedly in recent years, running at approximately 70-80 per year.
This has led to serious pollution incidents, with 28 reported between 2015 and 2023, including 6 caused by rising mains, accounting for 21% of serious incidents during that period.
Wessex Water is taking steps to address this issue, with a £2m project in Warminster nearing completion.
