Since March 2000 group water schemes associated with quality deficient private sources are eligible for a 100% grant for the installation of water treatment and disinfection equipment. To ensure the most cost effective delivery and operation of such equipment, and to secure long-term protection of the related capital investment, my Department's procurement policy in this area is based on design-build-operate contracts, coupled with the bundling of individual projects under a single contract. The same policy applies to smaller public water services schemes. My Department has recently produced a comprehensive procurement guidance document to assist local authorities and group schemes in the implementation of this policy and I am arranging to have a copy sent to the Deputy.
