Our knowledgeable and experienced team, provide a full asset assessment to create a detailed method statement for safe network isolations conforming to strict DWI guidelines.

These include: pre-planning works to ensure water quality is maintained to the highest levels, control strategies and contingency plans detailing network configuration or pumping strategies, to maintain water supply avoiding CGS, SI4 and SI12 points.

The optimisation of leakage surveys by ensuring correct pumping strategies are in place and they are scheduled at the at the most beneficial time of day. Better understanding of trunk main hydraulics can ensure maximum benefit from existing internal acoustic trunk main leakage detection methods.

Early detection and repair of trunk main leaks is crucial to minimise the likelihood of catastrophic failure which can lead to significant disruption and risk to the general public.
