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.
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.

USB interface takes multi-functional
counter to next level
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-
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.

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.
