Phase 1: Collection of available data and design of field work Phase 2: Field work .
Phase 3: Data analysis, clustering optimization studies
Phase 4: Preparation of detailed designs and tender documents (not
included in this presentation)
Part B: Planning of Rural Sanitation in the Project Area
The above methodology has been applied for Five districts (Motobas, Desoq, Alryad, Sedi
Salem, and Burullus).
Phase 1: collection of available data and design of field work
• Stakeholders engagement.
• Team building.
• Collection of available maps and drawings.
• Collection of data available on water and wastewater flows and
composition in the project area.
• Collection of demographic data and main economic activities .
• Analysis of collected data and identification of data gaps..
• Data collection on unit cost data related to wastewater projects.
Part B: Planning of Rural Sanitation in the Project Area
Phase 2: Field survey data collection, intended outputs
Part B:
Intended outputs:
The proposed clustering alternatives are field verified (roads, crossing,
….etc).
Proposed locations for pumping stations and treatment plants are visited
and assessed
Existing pumping and treatment facilities are checked and evaluated.
Pressure measurements for pumping stations are conducted and
analyzed.
Planning of Rural Sanitation in the Project Area
Phase 2: Field work
Part B:
Preparatory work prior to field visits
Formulation of basic engineering team for every district
ready with field data collection forms, GPS devices, and a
digital camera.
Formulation of a specialized team to assess WWTPs and
pump stations.
Formulation of a specialized team on flow and pressure
measurements in WWTPs.
.
Planning of Rural Sanitation in the Project Area
• Define planning criteria.
• Define basis of comparing among alternatives
• Develop clustering alternatives
• Selection of preferred alternative.
Phase 3: Data analysis and clustering optimization studies

Selection Criteria for Village and Classification
Part B: Planning of rural sanitation in the project area
• Data collection forms (Cluster level for field review).
• Guideline for field visit protocols.
• Explanatory note template.
• Guideline for finalization/ confirmation & optimized clusters.
• Current sewerage condition data collection forms.
• WWTP data collection forms
• Guideline for the Assessment of wastewater infrastructure needs in cluster
level.
• Forms for reporting meeting and interview with principle stakeholders.
• Guidelines for field of survey using GPS.

Cluster Definition
22
It is the Geographic Rural Sanitation Planning Unit (GRSPU) with defined communities to be served by centralized and decentralized systems.
(Cluster)منطقة الخدمة
The definition of the GRSPU boundaries is an optimization process
23
The sub-cluster Level (an array of villages)
It is part of the cluster. The array connects a series of villages, satellites and finally connect to the cluster WWTP by only one force main. The array can be used in prioritization on sub-cluster level in case of a limited available funds for all cluster projects.
