Media Release: Floods cannot be prevented, but mismanagement of waste water can

For immediate release
21 June 2023

“Ongoing cold fronts bringing torrential rain and flooding with significant damage to infrastructure, property and degrading valuable agricultural land and crops in the Western Cape are beyond human control, and with a changing climate South Africa will in all probability experience an increase of episodic rainfall events and flooding, and these can have destructive results, of which the 2022 KZN flood incident is a perfect example, ” says Cobus Meiring of the Garden Route Environmental Forum (GREF).

Globally, fresh water resources are increasingly under pressure as populations grow and rapid urbanisation and development impacts negatively on water availability and quality.

South African water authorities and municipalities are increasingly found wanting when it comes to environmental disasters that could have been prevented through  maintenance and the upgrading of water treatment plants, better trained staff as well as sufficient oversight and by dedicating sufficient resources. The present day threat to water security can however be addressed quite quickly to ensure better quality of waste water discharged after treatment resulting in healthier river systems to the benefit of down- stream water users and dependent eco systems.

South African authorities at all levels have neglected effective treatment of waste water over decades, and the deadly outbreak of Cholera claiming almost forty lives at Hammanskraal outside Pretoria in May 2023 is a horrific example of the result of what can only be described as gross neglect and incompetence, exacerbated by ever present power failures at pump stations. The Hammanskraal Cholera outbreak made headline news because of its deadly consequences, but what more often than not do not make the headlines is the effect of institutional failure to effectively deal with waste water on South African river health and eco system collapse. There are almost no river systems left in South Africa where the water is not contaminated to the point where it would be deadly to drink if not boiled or treated.

Responsible management of  waste water facilities and the protection of the country’s fresh water resources is entirely possible and absolutely not negotiable. This objective can be achieved through the training of dedicated staff dealing with water related tasks at all levels, sustained maintenance and upgrading of waste water facilities to cope with increased inflow of waste water, including sufficient technical capacity and know- how, oversight and experience.

Landowners also have a responsibility and a role to play in terms of water management

In the Garden Route and Southern Cape, the treatment of waste water is generally of an acceptable standard as a result of sound municipal management, but lots more can be done from an environmental management point of view. Aside from sticking to best water use management practices and extraction limits , landowners and land managers in the region should do more in terms of managing invasive alien plants on their properties, especially along rivers, streams and wetlands, and in the process contribute to ensuring the well- being of the environment and a higher quality of life for all living in the region.

The Garden Route Environmental Forum will be co- hosting its Climate Change and Environmental Management Indaba with the Nelson Mandela University at the George Campus on Thursday 29 June.

Media Release: Preparing for a changing climate indicates that all is not bad news for the Southern Cape

For immediate release
26 April 2023

“A battered economy and several high profile local and global challenges such as continued power outages and the Russian invasion of the Ukraine grips South Africa’s socio- political attention and at the same time  divert vital focus away from the growing impact a of a changing climate and the challenges it already pose,” says Cobus Meiring of the Garden Route Environmental Forum (GREF).

“Despite these challenges there are positive signs of sincere efforts to plan ahead, and GREF wishes to keep a clear view on climate change and the impact it has already  bestowed on the Southern Cape over the past decade, including unimaginable wild fire disasters in June 2017 and 2018, persistent drought and slow but measureable sea level rise resulting in coastal degradation, and as rainfall patterns change, the advent of episodic rain storms resulting in flash floods destroying millions of rand worth of often irreplaceable infrastructure.”

“ The present and predicted impact of climate change is well known and solutions to lessen and mitigate its impact are well chartered, but more often than not targets are difficult to achieve as government spending required to act pro- actively is subdued as a result of a shrinking local economy and a myriad of urgent socio- economic issues to address, including the needs of impoverished jobless communities, unsustainable rates of urbanization and the deterioration of South Africa’s vital infrastructure backbone including power, water, roads and railways and falling behind the global curve in modernization and technology.”

“ Despite all  the challenges mentioned,  positive progress is being made as South Africa and its citizenry does show a clear understanding of the challenges it has to prepare for, and with the private sector and private landowners investing on an unprecedented scale in ensuring their own future survival in terms of green and sustainable energy options and by putting water security measures in place, including fresh water harvesting , water evaporation prevention and reducing the presence of invasive alien plants on their land, topped by significant foreign investment packages such as western financial funding aid to assist the country towards a just energy transition are major positive strides and is setting a platform for a more sustainable future.”

GREF will be hosting its Annual Climate Change and Environmental Management Indaba on Thursday 29 June at the Nelson Mandela University George Campus.

The Garden Route Environmental Forum (GREF) is a public platform and climate change think tank for all those in the Southern Cape involved in active and ongoing conservation and environmental management efforts to meet up, interact and showcase what they are busy with and what they are doing in terms of planning ahead.

Media Release: Resource management, land restoration and legislation take centre stage in the Garden Route

For Immediate Release
13 December 2022

“The Southern Cape and Garden Route is experiencing rapid development and has to make provision to accommodate a fast-growing population, and this more often than not generates friction and anxiety between authorities and landowners where legislation and capacity to e.g. process applications hampers development or where various sets of legislation are seemingly contradictory where for instance land rehabilitation and invasive alien plant eradication is of concern,” says Cobus Meiring of the Garden Route Environmental Forum (GREF).

“ GREF is hosting its annual key- stakeholder report-back event on 13 December in Wilderness, where regional conservation and environmental management entities and individuals will provide insight on matters pertaining to resource management and land restoration.”

“There is a continued need to understand the linkages between ensuring a high standard of living in the Southern Cape, new development, loss of biodiversity, destruction of wetlands and wildlands and unsustainable pressure on natural resources such as water, and the finding of solutions for environmental challenges are increasingly relevant.”

“In addition to the matters mentioned above, the Garden Route is already experiencing and recording evidence of rising sea levels and climate change, and these are all the more reasons for those who share a concern for the state of the environment to make their voices heard and intensify the environmental debate in order to ensure that sustainability and resilience of natural resources remain top of the regional agenda.”

05 October 2022 Media Release: Garden Route District Municipality applies for an Alien Vegetation Control Programme Grant

Media Release: Garden Route District Municipality applies for an Alien Vegetation Control Programme Grant

For Immediate Release
5 October 2022

The Garden Route District Municipality (GRDM) has applied for a grant, through the Western Cape Government Provincial Treasury, to reduce the fire risk and improve the water supply. The proposed project, budgeted at approximately R29 million, will include a coordinated alien invasive species clearing, ecological restoration plan and community training programme. It is planned for the various catchments and rivers/tributaries and their habitats within the region.

GRDM Executive Mayor, Alderman Memory Booysen says that if funding is approved, the project will contribute to the integrated development of marginalised communities through income-generating invasive alien vegetation clearing projects.

“The GRDM and partners also plan to grow the community’s skills by enhancing their knowledge about identifying alien vegetation and clearing it,” he said.

More benefits of the proposed project include:

  • Restoration of ecosystem functions (i.e., nutrient cycling, habitat value);
  • Protecting biodiversity;
  • Initiating regrowth of indigenous plants;
  • Reducing fire risks;
  • Increasing water security;
  • Erosion control;
  • Enhancing tourism potential;
  • Restoring of wetland and estuarine functions;
  • Enhance tourism potential;
  • Improving agricultural potential of land (grazing and crops);
  • Long-term conservation of the mountain catchments, rivers, wetlands, and remaining natural; and
  • Facilitate the establishment of a positive working relationship between local communities and local government.

A lot of invasive alien plants (IAP) thrive throughout the Garden Route and its seven local municipal areas. Projections indicate IAPs could double within the next 15 years if something isn’t done soon. Such plants pose a threat to biodiversity, water conservation efforts, agricultural management and fire risk management.

Managing IAPs is based on two fundamental principles – acting early and following up. This includes initial control to drastically reduce the existing IAP footprint; and controlling seedling, root suckers and regrowth. Finally, maintenance to sustain low and decreasing IAP numbers will yield more positive results.

Dr Nina Viljoen, Head of Environmental Management says many alien plants consume more water than local plants, depleting valuable underground water resources, which results in additional fuel for veld fires. “Lower slopes, river floodplains and forest and scrub vegetation are largely invaded by species such as Acacia mearnsii and Acacia melanoxylon, amongst others, said Dr Viljoen”.

Alien plant invasions are estimated to have reduced mean annual runoff in the major rivers within the district by almost 20% by 2007 (Le Maitre et al., 2013).

13 September 2022 Media Release: Environmental Health Practitioners monitor river water quality

Media Release: Environmental Health Practitioners monitor river water quality

For Immediate Release
13 September 2022

Managing and protecting river systems are of utmost importance. Agricultural and land management practices, wastewater works maintenance, wetlands protection, and invasive alien plant control and eradication all play a role in the health of river systems.

“The Garden Route District Municipality (GRDM) is the official Water Quality Monitoring Authority of the Garden Route region. Environmental Health Practitioners (EHP) take water samples on a monthly basis to ensure that water intended for human consumption, recreation or use by industries is safe and complies with specific standards,” said Johan Compion, GRDM Manager for Municipal Health Services.

“The term water quality describes the physical, chemical, biological and aesthetic properties of water, which determine its suitability for a variety of uses and for protecting the health and integrity of aquatic ecosystems.”

Compion says the river water sampling and monitoring programme of the GRDM strives to provide accurate and consistent information. He added, “Sampling results assist to determine the main sources of pollution and to introduce specific interventions aimed at addressing these identified sources of pollution”.

The water quality monitoring function rendered by the EHPs of GRDM includes the following:

  • Monitoring of quality and availability of water intended for human consumption, recreation or use by industries;
  • Regular taking of water samples for analysis;
  • Identification and control of sources of water pollution;
  • Protection of water sources and resources by enforcement of legislation relating to the water quality;
  • Taking of samples for wastewater quality compliance;
  • Enforcement of legislation to ensure a supply of water safe for health (Water Services Act, 1977), Act No 108 of 1997) and South African National Standards (SANS Code 241).
  • Introduction of corrective and preventative actions (e.g., making recommendations to relevant authorities);
  • Implementation of health and hygiene awareness actions and education relating to the water supply.

Whenever risks can compromise safe drinking water in communities, the GRDM takes a preventative approach.

Sampling results serve to evaluate the suitability of the water of the various rivers for irrigation, livestock watering, recreational and domestic purposes and according to the following standards/ guidelines:

  • Wastewater limit values applicable to the discharge of wastewater into a water source in terms of the National Water Act, Act No. 36 of 1998.
  • South African Water Quality Guidelines: Agricultural use – Irrigation
  • South African Water Quality Guidelines: Agricultural use-Livestock Watering
  • South African Water Quality Guidelines: Recreational Use
  • SANS code 241 for drinking water

Typical water types that are monitored, sampled and analysed include, but are not limited to drinking water, rivers, dams, treated sewage effluent, recreational waters and industrial effluent. Rivers, which receive final effluent from Waste Water Treatment Works (WWTW), are of higher risk to human health, and water- and environmental pollution. EHPs inspect WWTW, and do water sampling to ensure that the final effluents are safe to discard in rivers and the environment as per specific WWTW permit requirements.

The applicable legislation is enforced by EHPs and is stipulated in the Constitution of the Republic of South Africa, Act 108 of 1996, the Water Services Act, no 108 of 1997, the National Water Act no. 36 of 1998 and the National Health Act no. 61 of 2003.

The GRDM with an area of 23 331km² is a Category-C Municipality and comprises seven local municipalities: George, Mossel Bay, Knysna, Bitou, Oudtshoorn, Hessequa and Kannaland.

Criteria used to determine high-risk and low-risk rivers, include:

Rivers that receive final effluent from Waste Water Treatment Works, are regarded as high risk to human health.

The rivers in the GRDM region where EHPs take water samples monthly include the following:

A. HIGH RISK
A) Ruiterbos Paardekop River
B) Heidelberg Duiwenhoks River
C) Riversdale Goukou River
D) Oudtshoorn Olifants River
E) George Gwauiing River, Schaapkop River, Molen River
F) Mossel Bay Hartenbos River
G) Plettenberg Bay Ganzevlei
H) Kurland / Plettenberg Bay Sout River
I) Zoar and Ladismith Nels River
B. LOW RISK
A) Oudtshoorn Grobbelaars River
B) Mossel Bay Klein Brak
C) Knysna Salt River and Bongani
D) Plettenberg Bay Piesang-, Keurbooms-, and Ganzevlei River
E) Plettenberg Bay Touw and Kaaimans River
F) George Garden Route Dam
G) Mossel Bay Kleinbrak and Grootbrak Rivers

All relevant role-players, municipalities and state departments must be involved in serious cases of river pollution. Where necessary EHPs advise water users on appropriate treatment options in accordance with the usage of the water and the specific determinants (total Coliforms, E-Coli and Faecal Coli organisms) not complying with relevant standards or guidelines. The “polluter pays” principle is applicable in cases of continuous pollution of water resources. EHPs report non-compliance to water services authorities and institutions to implement rectification measures in cases of unsafe and unhealthy conditions and health hazards.

What is the difference between a Water Services Authority and the GRDM Municipal Health Services?

Collaboration between local municipalities, the Department of Water Affairs, the Department of Environmental Affairs, other government departments and private entities, as well as all relevant role-players, will ensure that short-, medium- and long-term goals are reached, to ensure clean and healthy river systems.

A Water Services Authority (WSA) is any district municipality or metropolitan or local municipality that is responsible for providing water services to end users. A water services authority may either provide water services itself (an internal mechanism) or contract a water services provider to provide water services (an external mechanism).

Municipal Health Services is a function of District Municipalities, and the EHPs perform water quality monitoring as part of their municipal health functions, which include the following:

  • Monitoring of water reticulation systems
  • Monitoring of quality and availability of water intended for human consumption, recreation or use by industries
  • Regular taking of water samples for analysis
  • Identification and control of sources of water pollution
  • Protection of water sources and resources by enforcement of legislation relating to the water quality
  • Enforcement of legislation to ensure a supply of water safe for health (Water Services Act, 1977 Act No 108 of 1997) and SANS Code 241
  • Introduction of corrective and preventative actions (e.g. making recommendations to relevant authorities)
  • Implementation of health and hygiene awareness actions and education relating to the water supply.

20 June 2022 Media Release: Environmental management and climate change under the spotlight at Garden Route Indaba

Media Release: Environmental Management and Climate change under the spotlight at Garden Route Indaba

For Immediate Release
20 June 2022

The Annual GREF/Garden Route Environmental Management and Climate Change Indaba will be hosted by the Garden Route District Municipality (GRDM) and the Garden Route Environmental Forum (GREF) in Wilderness on 23 June 2022.

The theme for the event is:  “Preparing the environment for a changing climate.”  The Garden Route has been feeling the brunt of climatic changes during the past few years, manifesting in the form of unprecedented wildfire disasters and prolonged drought, in especially, the northern parts of the district as well as severe flooding in some coastal areas in November last year. In order for the GRDM to better prepare the region for what lies ahead in terms of climate change, stakeholders will gather to share experiences and ideas.

The Annual Garden Route Environmental Management and Climate Change Indaba in George is an institutional arrangement, and it continues to provide a strong and valuable platform for cooperation and communication between all entities on matters central to sustainable environmental management and climate change.

Environmental management under the spotlight following the Durban flooding disaster

“For years to come Durban and the surrounding countryside will suffer from, and personally experience the deadly and destructive impact of the 2022 floods. Government, as well as landowners and resident communities, will do well to learn and act from what happened, and that set of impacts also apply to the flood-prone Southern Cape and areas elsewhere along the coast and the interior of South Africa,” says Cobus Meiring, programme director for the Garden Route Environmental Forum (GREF) event.

“Besides substantial and traumatic loss of life in Durban, the damage to the environment and hard infrastructure is significant and will require enormous amounts of money and human resources to recover and rebuild from scratch.”

“History proved many times over that KwaZulu-Natal is prone to flooding and should have been better prepared to deal with these events as and when they occur, but this time around, nobody could have foreseen the severity of the recent flooding.”

Says Meiring: “In hindsight, however, there were several actions and interventions that could have made a significant difference in nurturing and better managing the surrounding natural infrastructure (rivers, wetlands, catchments and feeder streams) in order to soften the blow to the city and environment. Many lives could have been saved and billions of rand damage to infrastructure and the significant knock-on effect to the already battered economy could have been prevented.”

“There are obvious and practical ways to better prepare any city for flooding and dramatically reduce the impact of severe flooding, such as ensuring that stormwater systems are permanently clean and free of obstructions. More often than not the dire state of many of our rivers, streams, catchments and wetlands detrimentally reduce their ability to deal with floods and the critical function they deliver.”

“Perhaps because of the costs associated with eradication and clearing, the destructive effect of invasive alien plants (IAPs) on natural infrastructure must be understood.”

“River systems clogged up by IAPs cannot fulfil their basic role which is to channel rushing waters and prevent damage to riverbeds and riverbanks. When invasive alien plants replace indigenous vegetation, rivers cannot keep soil structures intact and assist with recovery following floods. Vast amounts of invasive plant biomass washed away by flooding rivers in Durban accumulated en masse against infrastructure such as bridges, stormwater channels and culverts, and in the process caused their total destruction resulting in even more severe downstream devastation.”

According to Meiring, the function and ability of wetland systems to dramatically reduce the impact of flooding waters are still misunderstood. “Their unfortunate destruction over time – through channelling and draining the water they retain and release to make way for development and farming – and invasive alien plant encroachment worsened the Durban flooding exponentially.”

“Thousands of tons of litter and plastic washed down by flooding rivers are sure signs that rivers and catchments are used as dumping sites, and in the process lead to riverbank and hard infrastructure destruction. By reducing illegal dumping this effect can be reduced,” says Meiring.

“Illegally built structures along riverbanks, steep slopes prone to landslides and structures in low-lying areas prone to flooding will increasingly become a death trap as the likelihood of severe flooding increases with changes in rainfall patterns and as the impact, driven by climate change, take effect.”

“Lastly, in high-risk areas, local and regional authorities should invest in early warning systems and evacuation procedures. It is also critical to consider awareness creation and public consultation to ensure that community safety becomes a bigger priority,” adds Meiring.

17 June 2022 Media Release: World Day to combat desertification and drought: Blossom’s Emergency Pipeline Project

Media Release: World Day to combat desertification and drought: Blossom’s Emergency Pipeline Project

For Immediate Release
17 June 2022

The Greater Oudtshoorn region continues to be plagued by ongoing droughts, and alternatives have had to be found to ensure water security for the region. Since 2018, the water supply from the Raubenheimer dam was under severe pressure as the amount of water available from the dam, exceeded the amount that could be relied upon with a 98% degree of assurance. The future and ongoing supply of water in the Oudtshoorn area is severely constrained and drastic measures had to be planned to address the situation urgently.

Furthermore, the Vermaaks Rriver boreholes near Dysseldorp are used to maximum capacity and the Huis River, which supplies De Rust with water, is unreliable during the summer months, which holds negative implications for the Klein Karoo Rural Water Supply System (KKRWSS).

The Blossom’s Emergency Pipeline is a project that was started in 2001 to investigate and develop alternative and additional water supplies for the Oudtshoorn area. Nine deep, and three monitoring boreholes were drilled in the Blossom’s wellfield, which were monitored and tested for 13 years. The test was completed in 2014, and it was concluded that the boreholes yield enough groundwater to supplement the water supply from the Raubenheimer Dam. It was determined that 60l/s (5Ml/day) can be supplied from 5 existing boreholes within the C1 Blossoms wellfield. The test also found that the impact on the environment would be minimal.

The Department of Water and Sanitation (DWS) approved a license for the total yield of 8 million m3/a for the ultimate full development of the Blossoms wellfield and gave the nod for the construction to commence. Originally, the project was intended as a medium to long-term bulk water augmentation intervention but given the current water crisis in the Oudtshoorn area, it will be implemented soon.

Funding for the current phases of the project, which started in February 2022, comes from the Municipal Disaster Relief Grant, which allocated a total of R47 million. To date, more than R150 million was spent, which was co-funded by DWS and Oudtshoorn Local Municipality. The current phase of the project is expected to be completed by March 2023.
