The report stated that the failure rate for the standard reinstatement was 14 per cent in September 2007. This was down from a 35 per cent level in 2002. The government-owned Northern Ireland Water’s (NI Water) failure rate stood at 19 per cent in September 2007. The company is responsible for 60 per cent of all road openings.

A statement from NI Water said “We are very focused on our role as a responsible corporate citizen in Northern Ireland and we have introduced a range of initiatives aimed at reducing the impact of our works.

“This includes increased use of Trenchless Technology which reduces the need for reinstatement.”
