We aim to achieve quality through a continuous improvement approach. This includes minimising variation, focusing on prevention rather than correction, setting targets and reviewing progress towards those targets.The inter-relationship of water with other essential components of a sustainable society is equally important. Greater use of energy purely to improve water management is short-sighted – it is the integration of infrastructure provision which provides the exciting opportunities, not just technologically, but also economically and socially. This is the unique ability of Nilan: to balance leading edge skills, not just in water engineering but also in integration of environment, social and economic understanding, in a way that offers the prospect of a truly sustainable future.
