ROUND UP

alarmed by the continuing water and sanitation challenges

Vandalism indefensible CESA abhors the neglect and damage to infrastructure especially owing to vandalismand theft. The tendency to destroy what is meant to improve the quality of life of our people as a basic human right is indefensible and our communities need to be informed that they are shooting themselves in the foot, since the money that should have been used to improve infrastructure delivery has to be rerouted to replace the damage caused by vandalism and theft. Finding solutions “We are appealing to the people to look after the infrastructure provided so that we can assist the government in accelerating ser- vice delivery throughout the country. With the backing of over 537 member firms, CESA is willing and able to partner with government and other key role players in finding lasting and practical solutions to these water challenges, especially in relation to infrastructure development,” says CESA Acting CEO Wally Mayne. Strengthening oversight role CESA lauds the Committee’s resolve to strengthen its oversight role not only in this municipality but with municipalities across the country to ensure that similar challenges are addressed and that the people of this great country receive quality services.

Consulting Engineers SouthAfrica (CESA) is alarmed by the continu- ing water and sanitation challenges at Madibeng Local Municipality, in North West. The challenges were witnessed during a recent site visit by the Portfolio Committee onWater and Sanitation, who con- sidered them to be symptomatic of the challenges across the country. Negative impact While these challenges need urgent action, the Committee noted the negative impact caused by the high rates of vandalism and theft to water infrastructure that is adding to the already critical challenges. The continuing vandalism and theft of valves, copper and transform- ers is a direct contributor to water shortages in many instances and has a negative effect service delivery by the financial resources of the municipality as money budgeted for other purposes, is diverted towards the replacement of these missing components. Infrastructure projects underway Within Madibeng, the Committee noted and appreciated various infrastructure projects underway such as the R63,7 M Wastewater Infrastructure Refurbishment Project as well as refurbishment of water supply pumps at various areas, but there remain a few chal- lenges that require urgent action. “Maintenance of the infrastructure will prolong the lifespan of water supply infrastructure and there is an urgent need for a col- laborative effort by all government departments from national to local level to remedy this situation,” said Mlungisi Johnson, the Chairperson of the Committee. Ease of use has been taken to another level with Hengstler multifunc- tional counters which are now available with a USB interface. This allows the user to programme the versatile counter via PC or tablet using the company’s free downloadable programming assistant. It not only provides a clear, user friendly display but will also recognise and alert the user should conflicting entries be attempted.The programme settings can be printed or saved as a file for record keeping purposes and programming is done via a USB interface cable or USB flash drive connection.The USB interface on the HengstlerTico 773 allows both the import and export of numerous values and settings including count value, presets, subtotals, totaliser and batch counter. It also facilitates output monitoring with a notification of any changes in the outputs. The HengstlerTico 773 offers reliable and accurate operation in a wide range of applications including position indication, rotation speed controlling, time controlling and batch counting.The easy to read dis- USB interface takes multi-functional counter to next level

Photoelectric sensor In applications where space is limited and high precision is required, the new generation of compact O7 photoelectric sen- sors from ifm electronic come into play.The precise background

suppression is particularly reli- able, even in the case of highly reflective objects. The visible light spot, without scattered light, enables easy alignment of the sensor to the object.The powerful photoelectric sensors with small design now come with NPN out- put, ideally suitable for position detection in feeding and handling.

The sensors serve as through-beam, retro-reflective and diffuse reflection sensors with fixed setting.The diffuse reflection sensor comes with precise background suppression and a small light spot to detect small objects.The small photoelectric sensors of the O7 series provide an ideal solution for confined spaces or for detection of small parts. Users are free to choose between units with PNP or NPN output.The sensor with a small light spot and the narrow light cone ensures detection of small objects even over long distances. The sensors with fixed settings are ready for operation immediately post plug and play installation. The diffuse reflection sensors are available with background sup- pression of 30, 50 or 100 mm range. Enquiries:Tel. 012 450 0370 or email info.za@ifm.com

play with large digits (9,3 mm x 7,2 mm) make it simple to use, while the installation of the device is easy due to plug and play style terminals. Enquiries: Gerry Bryant. Tel. 011 615 7556 or email bryant@countapulse.co.za
