Knowledge‐Based Wastewater Decision Support System (WWDSS) Water and Wastewater Management Programme- GIZ in Egypt Deutsche Gesellschaft für Internationale Zusammenarbeit (GIZ) GmbH, GIZ

WWDSS allows for improving project selection and optimising portfolios through increased coherence between national policies, sectorial policies, resource allocation and spending practices, and improved knowledge management. Utilizing WWDSS to identify cost‐efficient interventions in the wastewater sector and utilize it as a platform for strategic advice and monitoring of the financial performance of the ACs is done as follows:
1. According to the community needs (centralized /Decentralized services, unserved communities) the service areas are defined using the cluster optimization module is used to define a List of target villages, cost estimate for cluster, financial/economic viability and sustainability.
2. The unit cost module is then used to calculate the Quantity survey and unit cost for different elements and material of WW projects
3. The Financial module -at project level- is used to calculate the financial costs (CAPEX/OMEX) and revenues of the of the new projects
4. The financial module –at the national level- simulates the financial consequences and assess the financial viability of WW investment planning alternatives and their impact on the financial statement of the ACs
5. The wastewater reuse module is used to define the different possible treated wastewater reuse options, best options, the revenue of each option, estimation of the required investment, O&M costs
6. The sludge reuse module is used to define the different possible treated wastewater reuse options, best options, the revenue of each option, estimation of the required investment, O&M costs
7. The fund raising module helps in match making between funding agencies (local and international) and the projects seeking funds.
8. The management module helps in proposing the best approach to wastewater management projects
9. The economical predicts the socio-economic benefits at ACs, development and employment opportunities, & potential economic growth that goes with it
10. The Priorities & Investment Planning Module is used to prioritized the projects implementation accordion to the allocated investments, environmental, demographic, social, operational criteria at local and national levels.
11. Upon approving the fund, tendering documents are prepared by the MPU staff. And upon the Monitoring & Evaluation Module is used during the implementation of the project.
12. The database module stores detailed data about demographic structure, Existing wastewater infrastructure, under construction projects and planned in each ACs in a chronological historical order. The databases of the 23 ACs are linked via a wide area network (VPN).
13. A video conferencing that communicate the 23 ACs with the HCWW is now available through the VPN alongside the internet access.
WWDSS is adapted to a more complex environment, broadening the comprehensiveness of decision making, and aligning it to programme‐based approach (PBA), which help streamline the efficiency of its operations and improve organisational knowledge, thus increasing value for money. These achievements translate into sustained impact on health, sanitation, irrigation and by extension enhance agricultural outputs and food security.
