THE microbiological pollution of the Berg River has been investigated by consultants appointed by the Municipality. Lyners
Consulting Engineers, in association with Ninham Shand Consulting Engineers, presented the report at the Mayoral Committee meeting yesterday.
The report identified several high density informal settlements and confirmed earlier findings that very few people within these
areas have access to basic water and sanitation services.
"People relieve themselves on river and channel embankments, open spaces and in isolated cases over utilise chemical toilets or
block toilet systems."
Inadequate waste removal adds to the problem as solid waste is thrown into rivers and stormwater canals by shack dwellers.
Funding of R8,6 million would be needed to address various emergency projects to reduce pollution from informal settlements.
An amount of R55,6 million will be needed for longer term solutions and projects, among which basic services for informal
settlements, and a possible Newton Canal Wetland.
The consultants recommend an integrated approach, with a core task team consisting of members of the Municipality's Housing, Town
Planning en Engineering Departments. Their task will be to plan and co-ordinate activities which affect informal settlements.
They also recommend facilitation with and awareness and involvement of the community.
In the meantime farmers between Wellington and Hermon have expressed their concern on the deterioration of the river and say it is
influencing their farming and the health of their workers.
Standing on the bank of the river, Bertie Grobbelaar points out the black sediment on the bottom of the stream.
"The deterioriaton is unbelievable. When I was a child, we caught freshwater shrimps here. Now, you are lucky of you see a fish."
The stench from the water is overpowering, and after a few days in a reservoir, it is useless for human consumption.
"We are still lucky," he explains, "because we have our own borehole that provides drinking water to us and the workers."
However, the water is still used for everything else, from laundry to irrigation.
"It is also impossible to keep the children out of the water. The result is that there are often stomach complaints among them."
The same is true of the workers working with the irrigation system.
His son scooped some water from the river, to demonstrate the stench and filth. About ten minutes later his forearms were covered
with red spots, presumably from the water.
Further along the river, people are solely dependent on the river, and many of the farmers have had to install filtration systems,
at great financial cost.
"It was the only way out," one farmer said. "My workers and especially their children were forever ill.
"What is more, the heads on the irrigation systerm were continuously clogged by the filth (some of it indescribable) in the water.
"The moment we started to filtrate the water, people's health improved."
The Democratic Alliance, official opposition in the Drakenstein Town Council, has expressed concern on the pollution levels, the
health risks as well as the possible detrimental effect on the fruit industry.
They warned that the Mayor, his committee and the Council, may be held responsible for any damage sustained by any person, should
treated run-off water which does not comply with the legal directives, be pumped into the Berg River.
On pollution from informal settlements, the report states that the micro-biological pollution from raw sewage in virtually all the
stormwater drainage pipes and canals is a major concern.
"None of the people in the informal settlements have any access to sanitation. Even in areas already formalised, informal backyard
structures have been added, resulting in double the number of people planned for."
So-called "grey....." water and food scraps can often be seen deposited into the storm water catch pits and other inlets.
"Although this matter does not directly carry bacteriological pollution, it provides nutrition, adding to the life of the bacteria.
"To add to the above situation, solid waste remocal services are limited to centrally placed skips in the informal areas. The skips
are not effective in keeping the areas clean.
"This worsens the problem exponentially, since most of the solid waste is thrown into rivers and open stormwater canals, serving
also as nutrition to the bacteria in the polluted drainage water."
Both the food and other solid waste seriously hamper the flow of the stormwater systems, resulting in standing water where
concentrations of bacteriological growth occur, with the situation particularly bad in summer when irrigation of crops also take place.
"It is fully realised that due to the complexity of the situation, the situation will also be complex and a long process.
"The situation may in some instances require some short term solutions to address the symptoms, while the planning and
implementation of medium and long term solutions to address the causes take place."
The Irrigation Board appointed Dr Jo Barnes, epidemiologist and senior lecturer at the Faculty of Health Sciences at the University
of Stellenbosch in November 2002 to investigate the quality of the water and advise the Board regarding the matter.
Dr Barnes submitted various reports as well as memorandums, both to the Municipality as well as the Department of Water Affairs
& Forestry in which I have clearly stated that the quality of the water in a number of places in the Berg River is not suitable for drinking water or the irrigation of edible produce.
"It could be dangerous to humans and animals, when it comes to recreation, irrigation, washing or drinking."
Dr Barnes measured an E-coli count of 2,44 billion per 100ml water in the Berg River at a Mbekweni stormwater outlet last summer,
the result of fecal waste running into the river from unserviced shack areas.
Contributing to the problem could be an inadequate sewage system in the area. Lower down the E.coli count was 7000 per 100ml water,
still much higher than the informal standard for clean water and irrigation (a maximum E-coli count of 2000/100ml).
Drinking water may not contain any traces of E-coli and any measurement above 500 units per 100 ml is considered dangerous for
human contact.
According to Edie Malan, chairperson of the Irrigation Board, they have submitted various reports to the Drakenstein Municipality
and have had numerous meetings, also with the Department of Water Affairs & Forestry, regarding the pollution that is caused by the flow of raw sewerage into the Berg River from the Mbekweni and Fairyland
residential areas.
"After continued investigations, we know that the informal housing structures are causing raw sewerage and household waste water to
be dumped into the stormwater drainage system of the Drakenstein Municipality.
"The system carries this pollution into the Berg River, between Paarl and Wellington. Not only does this affect the 400 farmers and
approximately 12 000 hectare of agricultural land that is irrigated, but we also believe that the pollution of the Berg River's water is harmful or potentially harmful for the well-being, health and safety of the
people and animals who come into contact with the water."
