Assignment Title: Consultancy Services for Diagnostic Study on Energy Efficiency Improvements in Water Pumping and Distribution Systems under the Ministry of Water Energy and Minerals – Zanzibar.

Reference No. TZ-MOWEM-464920-CS-CQS

The Revolutionary Government of Zanzibar (RGoZ), through the United Republic of Tanzania, has received financing from the World Bank toward the cost of the Zanzibar Energy Sector Transformation and Access Project (ZESTA), and intends to apply part of the proceeds for consulting services.

Objective of the Assignment

The main objective of the assignment is to carry out a comprehensive diagnostic assessment of energy use in public operating boreholes for water pumping and distribution systems, identify losses and inefficiencies, and propose technically, and financially viable energy efficiency improvement measures. The study should also recommend a roadmap for implementation, including required investments for rectification for short, medium and long investment in energy efficiency technologies and operational strategies.

Scope of Work

The scope of work for the consulting firm shall include but not be limited to:

Baseline Assessment requirements

• Review existing water supply and pumping infrastructure including pump types, capacities, age, technology usage, maintenance records, and operational schedules.
• Map energy consumption patterns by time of day (electricity/fuel) across different facilities.
• Assess the current electricity billing structure, tariff rates, and energy costs.
• Evaluate system performance, water losses, and pumping efficiency.
• Assess the current electricity availability by time of day(See attached annex 1)
• Assess current water pumping capacity and availability versus current demand

Energy Audit and Technical Diagnosis

• Conduct detailed energy audits for major pumping stations and water distribution facilities.
• Analyse pump curves, efficiency data, and match pump capacity with system demand.
• Use appropriate energy or power measuring equipment power consumption, flow rates, and pressure levels.
• Identify opportunities for renewable energy solutions for lower cost and more reliable supply of electricity and water

Identification of Efficiency Improvement Measures

• Identify technical interventions (e.g., VFDs, pump resizing, leak detection, automation) and non-technical strategies (e.g., load shifting, operational changes).
• Estimate potential energy savings and greenhouse gas (GHG) emission reductions in Water system.
• Conduct cost-benefit analysis and payback period estimation for each proposed measure.

Implementation Roadmap

• Propose short-term and long-term measures, prioritizing low-hanging fruits.
• Develop an investment plan and implementation strategy.
• Recommend monitoring and verification (M&V) protocols for tracking efficiency gains.
