INNOVATIVE SOLUTION FOR SEWERS
In response to the ongoing challenges faced by dysfunctional sewer networks in South Africa , experienced Civil Engineer Chris Nganga Kimaru has developed a groundbreaking solution - the Manhole Protector Grid ( MPG ). The MPG is a patented device designed to prevent blockages in underground sewer and stormwater networks by creating a resilient semi-permeable barrier inside sewer manholes . Positioned below the cover slab and above the pipeline , the MPG filters out foreign objects , preventing them from entering the sewer pipes and causing blockages that lead to sewage spillages .
Typically , sewer networks comprise of underground pipelines and manholes conveying sewage from properties both businesses and residential , to the nearest wastewater treatment plant . The MPG can be installed in both new and existing sewer manholes across South Africa and other regions facing similar challenges . Constructed from durable , noncorrosive materials , the MPG can be easily retrofitted into existing sewer manholes or included in new installations . Equipped with GSM and Sigfox-enabled IoT sensors and gateways , the MPG continuously monitors sewage flow rates , transmitting data to a management platform with an early warning system . This system alerts authorities to potential blockages , enabling proactive maintenance and reducing the risk of sewage spillages .
METALBOX SKYSCRAPER IS A TESTAMENT TO ENGINEERING INNOVATION
Energy Partners , in collaboration with Fairvest Limited , has set a new standard in sustainable architecture with the completion of the Metalbox skyscraper solar project in Auckland Park , Johannesburg .
Standing at 80m tall , with just under 15,000m 2 of lettable space , the groundbreaking project features building-integrated photovoltaics ( BIPV ) that generate up to 300 MWh annually , making it South Africa ’ s first solar façade skyscraper .
“ The Metalbox skyscraper project is history in the making ,” says Energy Partners ’ Chief Executive Officer , Manie de Waal . “ We ’ ve seen similar projects succeed worldwide . But it required both a visionary client and a committed team to set a new benchmark for South Africa ’ s green energy transition .”
The project incorporates two solar systems . Monocrystalline panels on the building ’ s sides provide energy efficiency and aesthetic appeal , performing well even in low-light conditions , while the roof features carport-type panels , optimising sunlight exposure while offering weatherproofing to services located on the roof .
Says Charl du Plessis , General Manager , Energy Partners , Power , “ Both systems utilise BIPV technology , which we ’ ve seen integrated into several iconic buildings around the world , including Japan ’ s Solar Ark and Denmark ’ s Copenhagen International School . This technology performs the incredible task of transforming conventional building parts into solar systems , enhancing functionality , aesthetics , and ultimately improved return on investment . For us to be able to successfully complete such a project in South Africa is a game-changer .”
A Challenging Feat “ The top priority for us was ensuring the safety of our installation team , who worked from lowered platforms ,” says du Plessis . “ Then we had to achieve adequate torque on the clamps for environmental resilience – no mean feat considering that the solar panels had to cover a total area of 1,259m ², making this South Africa ’ s largest custom-built commercial installation .”
Shading had to be carefully modelled to accurately predict generation forecasts , and the engineering design includes various aspects to ensure maintainability over the long term . Additionally , the project required close collaboration with regulatory authorities and had to undergo a glint and glare study to mitigate solar glare effects on neighbouring surroundings , building plan approval and embedded generation approval . www . energypartners . co . za
