Academics raise alarm over by-law restricting water testing

The City says research in its nature reserves is allowed but only with permission

A proposed by-law drafted by the City of Cape Town contains provisions preventing anyone — including civil society organisations and scientific researchers — from independently testing water quality in City-run nature reserves without written authorisation.

One civic organisation believes this is counter to the constitutional right to a healthy environment and also impedes the right to access to information.

The Draft Nature Reserves By-law aims to control activities in 23 nature reserves across the city as well as control access, research and monitoring. Concerns have been raised with a section dealing with research and monitoring, as it places encumbrances on independent monitoring of water bodies and species populations in important ecological sites.

In February, a concerted civil action was made to obtain regular water quality data on extreme pollution of the Milnerton Lagoon, which forms part of the Diep River estuary.

Section 21 of the draft by-law states that no person may “carry out scientific or general research or undertake monitoring projects” without written authorisation from the City.

If authorisation is granted, a research proposal must be submitted to the City and all findings must be submitted in a format determined by the City.

Anyone violating these conditions would be liable to a fine and failure to comply could result in the person’s vehicle being impounded.

As it stands, the by-law could be used to prevent independent monitoring of water quality to ensure the results are in line with those obtained by the City. “It could be used to prevent civilian oversight of such populations and allow pillaging of natural resources as has occurred elsewhere,” says the Milnerton Central Residents Association (MCRA).

Even if permission for research was granted by the City, the requirements imposed are “cumbersome and unreasonable on independent interested environmental groups whose activities pose no risk” the association said.

It added that the section was also “contrary to the principal of inclusion, transparency, and the City’s policy of encouraging co-operation with residents”.

“Gag” law

Senior Professor Leslie Petrik,of the University of Western Cape Chemistry Department said it seemed the City’s plan was “to let the fox guard the hen house”.

Petrik, along with retired Stellenbosch epidemiologist Dr Jo Barnes and Associate Professor at the University of Cape Town Lesley Green, have previously been accused by the City of making “a habit of detonating unsubstantiated bombshells in the media”. This followed a number of articles highlighting pollution on Cape Town’s coastline and in the Kuils River which receives discharge from the Zandvliet sewage works in Macassar.

Petrik said, “It has been a battle to get the City to own up to the huge contamination of our beaches, rivers and estuaries.” She said that were it not for the Organisation Undoing Tax Abuse (Outa) assisting in Milnerton, the pollution of the Diep River “would have been downplayed and swept under the carpet”. Until recently the City claimed the pollution in the Diep River was due to an algal overgrowth,” she said.

“Citizens have a constitutional right to a safe environment and access to information that will materially influence their choices, to avoid harm. The by-law in my view is a sneaky way to gag our and other independent voices and punish us,” she said.

Also at issue was the period given by the City for the public to comment on the by-law. The City posted the invitation to comment on its website on 24 February, with the period for comment closing 20 days later, on March 16. But the City contends that its public participation “took place from 1 February 2020 to 16 March 2020” which was within the stipulated 35 day period and said that “various advertisements and a media release were issued.”

Mayco Member for Spatial Planning and Environment Marian Nieuwoudt denied claims that the draft by-law aimed to stop, restrict or prevent research within its nature reserves.

“The requirement for researchers to obtain landowner permission to conduct research and monitoring has always been (and is currently) in effect. All requests received are evaluated by the Biodiversity Management Branches Ecological Management Committee. This is to ensure that research is conducted responsibly and provides important input into the management objectives of the nature reserve and/or environment concerned,” stated Nieuwoudt.

Water bodies in certain nature reserves are subject to periodic incidents of pollution. Zandvlei nature reserve was closed or partially closed at least five times in 2019 due to sewage spills, and water quality in the Diep River and Milnerton Lagoon, which falls within the Table Bay Nature Reserve, has deteriorated to the point where the provincial authorities issued a warning to the City last month.

It is uncontested that with less rainfall in summer, the Diep River becomes little more than a channel for discharge from the Potsdam Waste Water Treatment Works combined with flows from contaminated storm water drains.

Cape Town Water and Sanitation Department, led by Councillor Xanthea Limberg, was given 21 days from 12 February to provide the provincial Department of Environmental Affairs and Development Planning (DEADP) with its short, medium, and long term plans to end the ongoing sewage contamination of water bodies.

The City subsequently released its anti-pollution plans for the Diep River catchment on 16 March. The province took action after civic bodies elevated complaints to the Western Cape government in December last year.

Additionally, the City has consistently failed to provide publicly accessible results of the monthly water quality tests it conducts on its rivers, canals, and estuaries. While water quality results have been provided to Protected Area Advisory Committees (PAAC) and to residents’ associations that have requested them, some PAAC members, and chairpersons of both the Milnerton Central Residents Association and Fish Hoek Valley Residents and Ratepayers Association, have said they had to sign terms and conditions, which include not distributing results without the City’s permission.

Nieuwoudt said that requests to do research or monitoring inside a nature reserve must be sent to the Knowledge Manager’s email at She added that proposals would then be considered by the Biodiversity Management Branch’s Ecological Management Committee.

Dear Editor

Really? Surely the City can't be serious? In recent weeks I have felt a lot more relaxed and appreciative of a City that is coming to its senses in wishing to exercise a more open and transparent approach and wanting to build public trust.

This proposal is contrary to the City's efforts to reposition itself. The City needs to engage civil society and citizen scientists now more than ever.
