Master planning in wastewater management

Zone planning
Further to the compliance of the region Flanders with the Framework directive and Urban Wastewater Treatment directive, mother company Aquafin developed specific tools to determine the necessary investments in areas where sanitation is still a priority. The zone planning identifies where sanitation is best centralised or decentralised. Investment priorities can be defined in a dynamic manner.

Master planning
Based on the zone plans, investment needs and priorities are defined. The master planning tool defines and lists in a dynamic manner all projects that are necessary to comply with set out guidelines in the zone planning. Furthermore, it comprises investment programmes based on its predicted ecological return.

Taking into account all constraints, such as ecological, economical, technical and social characteristics, a mathematical model calculates the priority of each project. The master planning provides per treatment area an overview of all necessary remediation projects to achieve the required degree of treatment at minimal cost.
