Water Reconciliation Strategy Study for the Large Bulk Water Supply Systems: Greater Bloemfontein Area 22
7. INTERVENTIONS SELECTED FOR PRELIMINARY EVALUATION
7.1 Process
The Greater Bloemfontein Reconciliation Strategy study has produced a long-term strategy for the
management of reconciling water supply with demands. Following the determination of the water balance,
the Strategy followed a step-wise process to identify the most favourable interventions, or groups of
interventions, to meet possible future water requirement scenarios. The process is listed below:
Step 1: Identification of interventions
Step 2: Preliminary screening of interventions
Step 3: Key stakeholder review of selected interventions
Step 4: Scenario planning process
Step 5: Review of selected scenarios by the Study Steering Committee 1
Step 6: Obtaining public feedback on the scenarios
Step 7: Implementing interventions and initiating studies of interventions
This document records details of the interventions that were identified in Step 1 and describes the
procedure followed in Step 2, where the preliminary screening of interventions was achieved by means of a
Preliminary Screening Workshop.
Based on the outcomes of the Preliminary Screening Workshop, a preliminary list of interventions that
needed to be investigated further at reconnaissance/pre-feasibility level was documented in the Inception
Report which, in turn, informed the first draft of the Preliminary Strategy. A second workshop, held later in
the Study, helped inform the final Strategy. The final strategy includes a list of studies that the DWA should
undertake in order to ensure an ongoing reconciliation of supply and requirement.
7.2 Objectives of the Preliminary Screening Workshop
The Preliminary Screening Workshop was intended to present potential interventions in terms of timing,
cost, and yield. Combinations of different interventions were also considered to devise the set of best
possible alternatives to meet the water requirements of the Greater Bloemfontein Area. The objectives of
the initial screening workshop were to:
Assess the acceptability of the various interventions identified in previous studies in terms of
technical, financial, environmental, and social criteria;
Ascertain which intervention or combinations thereof would warrant further investigations at
reconnaissance or pre-feasibility level, and what aspects should be investigated in this study;
Augment the existing information with specialist inputs from the DWA and other key stakeholders;
and
Identify any other issues/concerns of stakeholders which could impact on the reconciliation of supply
and requirement.
7.3 Screening Workshop Starter Document
A Screening Workshop Starter Document was drawn up to provide information for discussion purposes.
The content was based on available documentation which could be used for strategic level decisions. The
workshop participants provided further information and critically reviewed the information contained in the
Starter Document.
1 The Study Steering Committee includes representatives from DWA Head Office and DWA Regional Office, Mangaung Metropolitan
Municipality, Motheo District Municipality, Naledi Municipality, Bloem Water, Department of Agriculture, Department of Rural
Development and Land Reform, and water user associations.
