"The Government wants to see 60 per cent of new housing to be developed on former brownfield sites and this target, coupled with restrictions on green belt land, means that potable water more frequently needs to be transported across contaminated land.
Trigon barrier pipe systems ensure this can be done in absolute safety and have been proven to offer long-term reliability".

Every Trigon fitting is supplied with an insert designed to maintain the integrity of the pipe.
