8 Water/Wastewater Work in Peru Presented to World Bank Committee
Following the launch event in autumn 2011, the German Water Partnership (GWP) continued the dialogue at a symposium in mid-September attended by representatives of more than 40 international organisations and delegates from GWP member companies. The theme of both events was “Water and Innovation, Solutions for Development – The German Experience”.
In front of this distinguished audience, Ingo Matlachowski – who has worked for the Gütersloh-based company Hermann Sewerin GmbH (Germany) since 1987 and was appointed Export Manager in 1999 – reported on the public-private partnership project that SEWERIN has been running in the Peruvian province of San Martin since 2010.
Five cities in this province, which were selected for the project on the basis of various criteria relating to water losses in their drinking water networks (see for example blue facts 2011, page 122 ff), were each given a complete set of water leak detection equipment. As part of the National System for Capacity Development in the Water Sector, local employees of the water supply companies underwent six months of practical training to enable them to pinpoint leaks quickly and successfully.
In his presentation, Ingo Matlachowski identified the four elements of a successful leak management strategy: Maintaining a constant water pressure in the pipe network, Active monitoring of the distribution network for leaks, Prompt repair of located leaks and Active network and resource management
Through the systematic implementation of this four-point strategy, water losses in the five selected cities have fallen below 40%. As of April 2012, a total of 1766 leak sites had been located and 60 managers and pipe technicians had been trained in water leak detection. Over the course of this project, the five water supply companies have so far reduced their economic losses by around 1 million US dollars.
In conclusion, Ingo Matlachowski said: “The vision behind this project fits in well with the shift in strategy taking place within the water department of the World Bank. While until recently the focus was on developing water sources, the emphasis is now switching to preventing water losses in settlements that already have a water supply.”

WTW (Germany), a Xylem company, is a specialist manufacturer of portable systems for environmental measurements. WTW’s lineup includes the waterproof (IP 67) Multi Line 3410, 3420 and 3430 handheld meters for either one, two or three parameters at the user’s choice and a range of Intelligent Digital Sensors (IDS) for pH, conductivity and dissolved oxygen measurement. The pH sensors and conductivity cells are based on WTW`s proven SenTix and TetraCon models, whereas the FDO 925 optical D.O. sensor is an entirely new development.
These unique sensors convert the analogue measuring signal into a digital one before transmitting it to the meter. The digital signal is insusceptible to interference and hence allows to use cable lengths of up to 100 m even with pH sensors. In addition, particularly thin and supple cables can be used. Each IDS sensor stores a set of individual data (e.g. serial no. and, most important, its calibration record) for documentation purposes and thus minimising potential error sources and allowing to exchange the sensors between different meters at any time.
A true highlight are the new plug head versions of the IDS sensors that can be clipped to cables of different lengths at the user’s choice. They can be connected not only to the MultiLine series of handheld meters, but also to the extraordinary new MPP 910 IDS and MPP 930 IDS depth sondes. Last but not least they can be used with the inoLab 9310, 9420 and 9430 laboratory instruments, too. No other system provides such a flexibility.
Water Protection Starts with Accurate Monitoring
Due to its scarcity, in 2010, the United Nations declared clean water as a basic human right. This right can only be enforced, worldwide, through the strict regulation of water markets and the constant control of quality.
The LAR (Germany) pre-warning system, ToxAlarm, continuously monitors drinking and surface water for harmful pollutants. This unique online toxicity analyser contains a highly sensitive bacteria culture, which constantly and independently produces biomass. This means that there is always enough bacteria for each new measurement. The analyser is ready at any time. Moreover, the risk of the test organisms being contaminated is removed, as every water sample is tested with a fresh amount of bacteria. Hence, purchasing or time consuming breeding of test organisms in a laboratory is not necessary anymore.
The LAR ToxAlarm reliably detects harmful substances resulting from industrial discharges. It is suitable for online monitoring as well as for laboratory use.

“Reduce your carbon footprint” is a phrase we hear more and more lately and there are numerous different ways to achieve this. One is to cut out carbon heavy applications, another is focused around reduction. Sometimes, however, reduction or removals are not an option. In these cases it’s all about making sure you get the most from your application.
Quality made in Germany
When it comes to the online measurement of pH, ORP, conductivity, chlorine, ozone, or chlorine dioxide, we leave nothing to chance. Because for over 60 years we have been developing solutions that are ideally tailored to the needs and requirements of our customers.
Multiparameter water monitoring probes help you to collect the largest volume of data during a single visit / deployment; none more so than the AP-2000 Aquaprobe from Aquaread (UK). This system allows users to capture all of the standard parameters found frequently on this kind of small 2” diameter probe (pH, ORP, EC, Optical DO and Temperature), but then it allows you to add further parameters, such as Depth, an ISE sensor such as Ammonium or Nitrate and finally an optical sensor such as Turbidity or Chlorophyll. No other 2” diameter, portable, instrument allows this level of data capture.

This probe, when combined with the GPS Aquameter, which records the precise location of your dataset via built in GPS, provides users with the maximum amount of data in a single round of monitoring. This enables people to get the most from their deployment and potentially reduce their carbon footprint.
