Water infrastructure encompasses everything from dams, reservoirs, water treatment
systems and water distribution systems, to wastewater and sewage collection systems, pump stations and wastewater treatment plants.
The failure of the water and sanitation infrastructure across many parts of South
Africa has become widespread as evidenced by the recent Blue Drop, Green Drop and No Drop reports issued by the Department of Water and Sanitation.
There are considerable challenges in determining the integrity of the water and wastewater systems and the associated scope of infrastructure leakages. With potable water losses (non-revenue water) as high as 45% in some areas it is likely that sewage losses into the environment directly from pump stations and pipelines, although unquantified, are also high.
The infrastructure failures owe much to a lack of proper management, refurbishment
and maintenance of the various systems. These issues are exacerbated by loadshedding, says Talbot CEO Carl Haycock, who adds that both water and wastewater treatment requires significant energy consumption for both treatment and transfer, including pumping over large distances and between catchments.
“Voluntary testing by Talbot’s in-house laboratory has demonstrated that municipalities
across South Africa are struggling to resolve challenges pertaining to the maintenance
and management of wastewater treatment plants, pump stations and associated
infrastructure.”
Talbot attributes the bulk of municipalities’ water infrastructure challenges to population growth, deteriorating infrastructure and insufficient or misallocation of funding.
In response to sporadic outbreaks of waterborne illnesses, such as cholera, Talbot has
heightened public awareness through numerous water-quality tests.
Following the identification of critical E.coli levels and the subsequent closure of
specific beaches in Durban during the holiday season, recent findings suggest that
these E.coli levels continue to remain elevated, especially after periods of rainfall.
This ongoing situation is concerning, as demonstrated by the voluntary weekly samples conducted in January. Haycock says that private-sector involvement (public-private partnerships) has been suggested as a panacea for the integrity failures permeating the water infrastructure sector.
He commends Water and Sanitation Minister Senzo Mchunu’s efforts to enhance
regulatory clarity and accountability through the proposed amendments to the Water
Services Act and the release, after a hiatus in the past decade, of the Green, Blue and
No Drop reports.
COSTLY PROCESS
Every cubic metre of water used in daily consumption has travelled for kilometres along pipelines and has been pumped, stored and treated, all of which have cost implications
These reports are positive steps in creating a greater awareness on the status of our
water supply systems, wastewater treatment systems, and the country’s water losses.
Such information could be integral to help redress the situation, in addition to highlighting the challenges facing local and provincial governments, as well as water authorities.
Talbot highlights the importance of using the energy crisis as a template, suggesting
that the state of water infrastructure may be a more difficult crisis to solve, especially
because the public will be less patient with water.
A Matter of Funds
Haycock expresses concern about the insufficient funding for the repair and maintenance of water treatment systems, especially in areas affected by natural disasters.
He emphasises that the proposed National Water Pricing Strategy envisions a system
that recovers the cost of management, maintenance and refurbishment, among other
factors, for water and sanitation infrastructure, from users.
This will place a significant additional cost burden on all water users with large users
bearing the brunt. “Every cubic metre of water that you use in your industry . . . has travelled for kilometres along pipelines – it has been pumped, stored and treated. It has had energy and chemicals used in its treatment, following its being piped from a dam – which cost millions, if not billions, to build.”
As part of its efforts to help establish key revenue streams in the water infrastructure
sector, Talbot stresses the need for water incentivisation projects that reduce the cost
burden of public infrastructure on the fiscus and for clarity regarding the separation of
public finances.
Haycock suggests that revenues generated from water should be reinvested in the sector as opposed to its being allocated to the general fiscus.
Using data to track water losses, manage consumers, and cultivate a sustainable payment culture is proposed as a strategy for the sector. Haycock highlights the potential collaboration between municipalities and the private sector.
Haycock also hails the involvement of the mining industry and its efforts to assist with
the operation of municipal water infrastructure, particularly on the wastewater side.
Although more effort is required from both sides to mitigate against a lack of trust,
there are positive indications with some mines willing to allocate their excess water
to municipalities.
He adds that long-term planning and greater expertise are crucial to ensure sustainable water provision for the future. Haycock concludes by shedding light on
Talbot’s multifaceted role beyond a laboratory or turnkey provider of solutions,
emphasising the company’s involvement in financing water projects and carrying
out water-security consulting projects from conceptualisation through bankable feasibility studies and detailed design to solution implementation.
