High levels of pollution in the Diep River system and Milnerton Lagoon continue to impact the wellbeing of local residents, but evidence suggests this situation will be slow to change.

Of the 16 conditions laid out in a January 2021 directive regarding the City of Cape Town’s clean-up of the Diep River system and Milnerton Lagoon, the city is currently compliant with only five, while being partially compliant with 10 and non-compliant with one.

These were the findings of the Western Cape (WC) directorate for environmental law enforcement’s environmental management inspectors, also known as the WC Green Scorpions, in an updated compliance audit issued on 29 October 2021.

The updated compliance audit showed that the areas of partial compliance were:

  • Expediting the investigation into illicit discharge into stormwater drainage systems and surrounds, and reporting on proposed actions to prevent this;
  • Submitting revised pollution incident protocols and contingency plans for Potsdam Wastewater Treatment Works (WWTW), Koeberg and Sanddrift pump stations;
  • Enabling the expediting of the upgrade of Potsdam WWTW;
  • Enabling the expediting of the upgrade of the Montague Gardens bulk sewer gravity reticulation network and screening system;
  • Enabling the expediting of the upgrade of the Dunoon and Doornbach sewer gravity reticulation network;
  • Enabling the expediting of the upgrade of the Koeberg Road pump station;
  • Submitting a sewer pump station audit report;
  • Increasing frequency of refuse collection and area cleaning, and submitting a plan to address the littering and solid waste pollution, in Dunoon, Doornbach and Joe Slovo Park;
  • Effectively sealing off all historical outlets and underground pipes leading from Potsdam WWTW into the Diep River;
  • Implementing measures at strategic stormwater outlets to trap all the general waste flowing into the Diep River and Milnerton Lagoon.

The area of non-compliance was:

  • Adding an additional sampling point at the final effluent discharge point of Potsdam WWTW.

The compliance audit is the latest development in an ongoing effort by the Organisation Undoing Tax Abuse and residents in the Milnerton area to have the high levels of pollution in the river system addressed, according to Andrea van Heerden, senior legal project manager at Outa. 

“[The pollution] has affected the health and wellbeing of those unfortunate enough to live close to the smell on a bad day, or to pick up an infection if in contact with the water,” said Caroline Marx, head of the environmental portfolio for the Milnerton Central Residents’ Association.

An independent water tester was employed by Outa to collect water samples at strategic sites along the Diep River throughout 2020. The results showed that the Potsdam WWTW, which is managed by the City of Cape Town, was discharging untreated or incorrectly treated effluent directly into the Diep River, according to Van Heerden.

“[Outa is] very cognisant of the fact that the pollution is not just [limited] to one specific incidence or one place, but through our water testing, we could find evidence showing that Potsdam is one of the major contributors,” said Van Heerden. Another significant factor behind the pollution problem is the lack of adequate sanitation infrastructure in the nearby Joe Slovo informal settlement, she added. 

Outa first became involved in advocating for a clean-up of the Diep River system in early 2020, after being approached by certain residents’ associations in the area for assistance, according to Van Heerden.

“Outa’s support has been game-changing — residents associations simply do not have the financial resources to cover independent water testing or the expertise of a legal team to prove non-compliance with the environmental laws,” said Marx. “[A]n independent third body like Outa is needed to ensure public oversight and accountability.”

In light of the consistently high pollution levels, and after several back-and-forth engagements with the City of Cape Town, Outa lodged a complaint with the WC Green Scorpions on 24 August 2020, according to a record of correspondence about the issue on Outa’s website

In September 2020, the Green Scorpions issued a directive against the City of Cape Town in terms of the National Environmental Management Act, laying out various conditions for the improved management of the Diep River system, according to Van Heerden. 

The city was required to investigate illicit discharges of waste into stormwater drainage systems in the area, expedite upgrades to water and sanitation infrastructure, and increase the frequency of refuse collection and area cleaning within Dunoon, Doornbach and Joe Slovo Park, among other conditions.

However, the city appealed the directive, claiming that the time frames for certain improvements were not reasonable, and an amended directive was issued and accepted 0n 22 January 2021, said Van Heerden. 

“The city had to submit an action plan saying what they were going to do,” said Van Heerden. “It went well for the first two, three months. And then afterwards, we started noticing that things were deteriorating.”

Outa’s independent water testing, which continued throughout 2021, showed that while the water quality improved in the first few months after the directive was issued, it then began to worsen once more, suggesting the city had regressed in their interventions, she said.

The Green Scorpions issued a compliance audit, evaluating the city’s fulfilment of the directive’s conditions, on 2 August 2021, said Van Heerden. The initial audit showed that the city was partially compliant with eight conditions, compliant with six conditions and non-compliant with two conditions.

After allowing the city an opportunity to respond to the compliance audit, an updated version was issued in October, said Van Heerden. 

In the updated audit, the condition to expedite upgrading of the Dunoon and Doornbach sewer gravity reticulation network had moved from “compliant” to “partially compliant”. The condition to implement measures at strategic stormwater outlets to trap all the general waste from flowing into the Diep River and Milnerton Lagoon had moved from “non-compliant” to “partially compliant”, according to a comparison of the audits.

For each area of non- and partial compliance, the October 2021 audit required the City of Cape Town to provide updated reports and reasons for compliance issues.

Issue of compliance

The City of Cape Town is working to “progressively achieve full compliance” with the Green Scorpions directive, with ongoing oversight through monthly public reports to local sub councils, according to Councillor Zahid Badroodien, the city’s mayoral committee member for water and waste.

Badroodien added that the timelines for infrastructure upgrades were still being reviewed. “The city is committed to completing infrastructure upgrades within the shortest possible time frames,” he said.

However, Van Heerden argued that the city has been given enough time to rectify issues and should not be seeking to shift completion dates that were agreed upon in the January 2021 directive. Failure to comply with the directive should be met with legal consequences, she said.

“We all know the state of our rivers, our natural rivers. What’s going on in our municipalities is nothing new,” said Van Heerden. “Once any type of action is taken, it sets a standard […] to enable normal citizens or civil society to take this further.”

Failure to comply with a directive is an offence, and a convicted person is liable to a fine not exceeding R10-million or to imprisonment for a period not exceeding 10 years, according to Rudolf van Jaarsveldt, spokesperson for the WC Department of Environmental Affairs and Development Planning. 

Van Jaarsveldt added that while the department does not support the City of Cape Town’s attempts to extend the timelines for compliance with certain of the directive’s conditions, it acknowledges the challenges faced by the city in terms of supply chain management and budget allocations.

The WC Green Scorpions currently have 51 active investigations against 16 municipalities, according to Van Jaarsveldt. Insofar as active cases, they have issued 10 directives, with an average of two directives issued per year between 2020 and 2021, he said. DM/OBP

    Please Green Scorpions also inspect Lourensriver ,Somerset West from Main road down to the sea ,where the problem lies.Above the main road everything is fine but from there nobody seems to worry.Friends of the Lourensriver talk lyrical about lourensriver above main road but conveniently forget that the whole lourensriver is declared a protected river right down to the sea.Pollution, people staying in the river ,defecating in the river ,increasing crime using the river bed to operate from at night ,terrorizing the inhabitants of especially Bridgewater just below main road ,somerset west ,Below the N2 on Strand side behind the vehicle test centre there is also lots of people staying on the river Bank defecating, washing, throwing plastic etc in the river.The water quality at the mouth of the lourensriver is also bad.

      Very good comment again. Just a question. Whose responsibility is it to clean up this mess in areas mentioned in the article, as well as those mentioned by yourself. If it is the City of Cape Town, then I presume it is the council of the city, basically at least 60% DA council members.
      I have experienced an almost similar situation in St Helena Bay, part of Saldanha Bay municipality. Many residents working for the ever-expanding fishing industry (the largest in SA) were complaining there was not enough land allocated to workers for housing. They started a massive protest. blocking roads etc. Of course the better off residents complained bitterly, and eventually the police arrived in masses, and inter alia killed a young boy, in his house watching TV (nobody has yet been found accountable). Now the interesting thing here is that hundreds of hectares of land was sold to to housing developers. Anybody driving through St Helena Bay would notice the large areas of land with street lights, fences, tarred roads, but no houses. Of all the huge numbers of developments, the housing numbers are less than 5%, and houses are not going up fast. These developments are of course catering for they better off people, fancy houses etc. But there was no land allocated for the influx of workers to work in the fishing industry. Again, like Cape Town, the municipality failed to do their job. Guess who was the controlling political party? Money talks, and that is not coming from the common citizen

        run for parliament Coen – be the difference you want to see.

          What the hell has parliament got to do with this….this is local municipal failures

          • jcdville stormers says:

            Coen I share your opinion 1oo %,it is Coct s duty.Seems like at many a municipality run by them the upper class or higher income is looked after but not the rest,equating to a “money party” If you don’t change the environment on the cape flats etc nothing changes.Building a play park in Hanover Park for example only 1 that really benefits is the contractor , because before long the gangs will have taken over the play park selling drugs from there.Tikkopppe will destroy it, breaking it down , selling iron etc to scrapyards.Schools with no adequate sports facilities will not keep kids occupied.A whole rethink on the cape flats is necessary.Lessen the influence of gangsterism by laws preventing anyone to belong to a gang.Anyway probably wishful thinking with all the politicians around following there own agenda!!!
