Case Study – Sabesp, S.Paulo

PASSAGEM FUNDA DISTRIBUTION

SYSTEM

1.East area of São Paulo

2.Population = 230 000 inhabitants

3.Pipe extension = 221 600 m

SABESP Case Study

Problem •50% water loss •Poor service(frequent supply disruptions)

Result •36.74 % water loss •~12.000.000m³ ~3 000 000 USD • Improved service

Solution • Pump management • New Pressure Reduction Valves (PRV) in critical points
