Mains Rehabilitation Strategy: Developing a Defined Program for Prioritization and Expenditure

It has been widely reported that this country's infrastructure is in need of a serious overhaul; this includes drinking water systems, many of which are now considered to be approaching the end of their useful life. Complete replacement of such assets would be the preferred option but budget and construction constraints make this unrealistic. Water quality and hydraulic requirements will not reduce though, so the system owner is left with the balancing act of providing maximum benefit to customers at minimum cost. Rehabilitation of water mains can extend the operational life of the asset at a reduced cost but the engineer needs to consider taking a rational approach to identify projects that are justifiable and beneficial. Development of a mains rehabilitation strategy will enable prioritization of the distribution network with an auditable expenditure profile. This enables the engineer to cost-effectively target defined areas of long term need rather than operating an expensive reactive program which will only provide short term benefit. This paper describes how successful water mains rehabilitation strategies have been developed in particular referring to a project carried out with New Jersey American Water, and how it should become a key part of an asset management plan. It outlines the key elements of the strategy and how it can be flexible to suit the needs of any utility without compromising output.
