Options development and appraisal for the Isle of Wight

Our approach to options development and appraisal (ODA) is explained in a technical summary.

For each of the wastewater systems selected for the options development and appraisal, we have identified the types of measures (options) that may be beneficial in reducing the risks to customers and the environment. These are the generic options. They are grouped into those that reduce the risks at  source (i.e. avoid or remove the risk), those that can be managed through investment in our wastewater system (the pathway) and those that mitigate the consequences on people or the environment (the receptors).  The list of generic options is shown in the table below.

Table of generic options

We commenced the ODA process at the river basin catchment scale (level 2 planning) in order to look across all the wastewater systems in the river basin and identified generic options that could work in the wastewater system.  The Generic Options are based on the drivers and causes of risks, and these will be investigated and developed further from a long-list of Unconstrained Options through to Feasible Options during the investment planning process.

The map below shows the Generic Options for Sandown. This provides an indication of the type of solutions we will be investigating further to manage and reduce the risks in the Sandown system that could have an impact on customers or the environment.
