Groundwater Asset Maintenance Requirements; Development of a UK Water Industry Standard Approach
The UK water industry relies heavily on ageing groundwater assets. An approach to maintenance planning is presented enabling water companies to develop more effective investment plans and achieve lower whole life costs, reduced serviceability risk and better security of supply.
This research pools experiences of different types of aquifers and failure modes including loss of reliable yield due to excessive drawdown, bacteriological failure, sand pumping, borehole collapse, turbidity failure and outage due to iron and/or managnese or other water quality parameters.
The resulting screening tool is based on a Generic Asset Life which is then adjusted to become a Modified Asset Life depending on actual performance and factors predisposing towards failure. Deterioration curves with or without rehabilitation may be estimated from case histories or site specific data. The forward planning tool, taking account of asset criticality, allows prioritisation of assets for investigation and rehabilitation or replacement.
