"Multi‑million dollar water infrastructure projects carry some of the largest corruption risks in the sector linked to the procurement of civil works and associated design, supply and consultancy services. The potential for grand corruption in big dam projects and upgrading urban water and sanitation systems can be so significant as to skew policy making towards the most lucrative investments. Grand corruption – involving a relatively small number of individuals but involving large amounts of money and an abuse of discretionary power – is the most significant risk in major infrastructure projects. Corruption may extend to such a high level (state capture) that national policy is influenced and, in turn, encourages decision‑making that favours activities that provide most potential for corruption."
