The Mambu Branco System

The project: Better water supply for São Paulo

The Mambu Branco system is part of the integrated water supply system of Itanhaém, near Santos, a city located on the south coast of São Paulo state. This system was extended to overcome water shortages and ensure a reliable water supply to this region in the future.

The client: Sabesp

Sabesp is a Brazilian water and sanitation company owned by São Paulo state, and is the sixth largest water and wastewater company in the world.

With water production of 105,000 l/s, Sabesp provides water and sewage services in residential, commercial and industrial applications to 60% of the population of São Paulo state (28 million people). 

Sabesp provides basic sanitation services, including all drinking water phases (extraction, treatment, processing, distribution) and the collection, treatment and reuse of sewage.

The challenge: Upgrading the existing system

In order to meet the increased drinking water demand, it was necessary to upgrade the existing system at the River Mambu and build a completely new supply system from the River Branco as the intake capacity of the River Mambu was not sufficient to meet the requirements. 

The extension included a dam, raw and drinking water pumping stations as well as a treatment plant (using dissolved air).

The solution: Water for 1,2 Million people which for decades had suffered from shortages in water supply

Dependability, reliable operation and maintenance-friendly design were decisive arguments to place the order with KSB. KSB Brazil supplied horizontal, axially split RDLO and RDLP pumps, submersible Amacan and Hydrobloc Drainer pumps and horizontal overhung Meganorm and Megaflow pumps for the project. Each pump type meets the needs of a wide range of applications in large systems such as the Mambu Branco system.

At the end of 2013, Sabesp was able to put the expanded Mambu Branco System at the service of the local population. The improved water supply system which comprises 66 km of water pipes benefited 1.2 million people in five nearby cities, 
which for decades had suffered from shortages in water supply. Increases in the population during the summer season will no longer compromise the reliability of the water supply.
