  4. The MontfleuryMicrohydropower Project The site is located in Tunis next to the administrative building of SONEDE.

  5. The MontfleuryMicrohydropower Project

  6. The drinking water network of the capital Tunis Reservoir of monfleury Ghdir el Golla treatment plant

  7. simplified diagram of the southern branch supplying the tank of montfleury

  8. Dissipation of hydraulic energy at the Montfleury breakwater

  9. hydrologicalanalysis Flow data The hydrological analysis of measurement data taken every hour over four (04) years has shown the following characteristics: - Average flow rate: 141 l / s - Maximum flow rate: 157 l / s Minimum flow rate: 111 l / s (overflow> 99.5%)

  10. hydrological data 98m abovesealevel The residual pressure: • The residual pressure at the Montfleury reservoir depends mainly on the pressure at the main pipe from ghedir el golla. • The pressure losses caused by the flow of the Montfleury reservoir have only a limited influence. A continuous measurement of residual pressure give the following results: between 35.5m and 45.0m Geodeticdifference: 53m 45m abovesealevel

  11. Which turbine to choose? Two solutions are possible: • a conventional hydraulic turbine, (Francis, cross-flow) • Pump as turbine (PAT: Pump as turbine) PAT offer the right solution in terms of investment cost and simplicity of operation and maintenance.

  12. Regulation of the turbine The turbine speed will be regulated to recover the maximum energy over the range of flow variation, using an asynchronous generator with regenerative drive (4-quadrant drive). Advantage: allows to valorize more hydraulic energy

  13. The necessary protections In case of disconnection from the electric grid: • rapid increase of the speed of the turbine (runaway of the turbine generator group) • water hammer Necessary protections against these phenomena: flywheel (9) and bypass valve (2)

  14. Main components of the Montfleuryhydroelectric project • Turbine: 160 l / s pump-turbine with a net drop of 45 m • Generator:cage asynchronous with four-quadrant drive (regenerative drive) • Protection in case of disconnection from the electric grid: flywheel and bypass valve

  15. Main components of the microhydroelectric project • 1. and 10. Motorized valve • 2. Differential pressure sensor • 3. pressure sensor • 4. Speed sensor • 5. Turbine-generator with flywheel • 6. Water level sensor • 7. Pressure reducer • 8. Water level sensor (for flow calculation) • 9. Measurement overflow • 11, 12 and 13 valves • 14 and 15. Flowmeter • 16 and 17. water level detectors

  16. Economicevaluation • The economic calculations were carried out with : • - Efficiency of the turbine-generator : 70% • - The annual availability : 95% • The electricity production will be 300 MWh per year. • The necessary investment (150 thousand euros): • hydroelectromechanical equipments •   measuring and regulating equipment • control system • Return of investment time : 4 years. (lifetime : minimum 20 year)

  17. conclusion and perspectives • Investments in micro-hydropower projects on drinking water systems are considered profitable with a relatively low cost per kWh produced. This is due to: •  the high load factor of turbines installed on drinking water pipes, •  the existence of civil engineering works ready to accommodate the turbines. • Several pressure reducers at SONEDE can be replaced by micro-hydropower (Identification of hydropower potential of : 4MW) For this purpose, SONEDE will launch tenders for the installation of other micro-hydropower plant. This example can be applied in drinking water and sanitation companies in the MENA region and in Africa
