The Water Quality Testing Procedures

Water is a vital resource that sustains life, and therefore, ensuring its safety and quality is of utmost importance. This is especially true for MANZI Water, where water quality testing procedures play a crucial role in safeguarding the health and well-being of its customers.

The Importance of Water Quality Testing

Ensuring safe, clean drinking water comes with numerous challenges, such as industrial pollution, agricultural runoff, and inadequate sanitation systems. Poor water quality can lead to a variety of health issues, ranging from gastroenteritis to chronic illnesses. Therefore, regular water quality testing is essential to identify potential contaminants and take appropriate measures to mitigate risks.

The Role of the Department of Water and Sanitation

In South Africa, the Department of Water and Sanitation is the primary authority responsible for water management and quality control. It oversees a comprehensive water quality monitoring programme that covers various water sources, such as rivers, dams, groundwater, and coastal waters, aiming to ensure that water resources meet the required standards set by the South African National Standard (SANS) and the World Health Organization (WHO).

Regulatory Framework

The regulatory framework for water quality testing in South Africa is outlined under the National Water Act of 1998. This legislation empowers the Department of Water and Sanitation to regulate and monitor water resources, establish standards, and enforce compliance.

Water Quality Testing Methods

Now that we understand the significance of water quality testing, let’s explore the methods used to assess water safety at MANZI Water.

  • Chemical Analysis: This is a primary method used to test water quality, involving the measurement of various chemical compounds present in the water. Parameters such as pH, dissolved oxygen, ammonia, nitrates, and heavy metals are analysed to determine the presence of contaminants and whether the water meets the required standards.
  • Microbiological Examination: This method focuses on detecting harmful microorganisms in water, such as bacteria, viruses, and parasites. Specialised techniques are used to culture and identify these microorganisms, assessing the risk of waterborne diseases and the effectiveness of disinfection techniques.
  • Physical Observation: Water quality testing also involves physical observation, assessing the colour, odour, and turbidity of the water. These observations can indicate the presence of contaminants that may affect water quality.

Water Quality Testing Laboratories

Accurate and reliable water quality testing requires specialised laboratories equipped with state-of-the-art facilities. MANZI Water utilises several independent laboratories that contribute to the water quality testing procedures.

Water Quality Testing Parameters

At every MANZI Water outlet, they ensure that their water undergoes rigorous monthly testing by independent laboratories, strictly adhering to the SANS 241 standards for drinking water quality in South Africa.

  • E. coli, a bacterial marker for recent faecal matter contamination, poses a severe health risk.

The MANZI Water Standard: Not detected

  • Total Coliforms, a diverse group of bacteria, are used to identify any post-treatment contamination.

The MANZI Water Standard: < 10

  • The Total Plate Count measures the overall microbial quality of water.

The MANZI Water Standard: < 1,000

  • Total Dissolved Solids (TDS) indicate the presence of minerals, salts, metals, and organic compounds in water. MANZI Water’s TDS levels are significantly below the SANS 241 guideline of < 1,000.

The MANZI Water Standard: < 20

South African Bureau of Standards (SABS)

The South African Bureau of Standards (SABS) is a nationally recognised body responsible for testing and certifying products and services. MANZI Water laboratories are accredited by the SABS to perform water quality testing according to national and international standards, playing a vital role in ensuring the accuracy and reliability of test results.

Conclusion

MANZI Water is dedicated to continuous improvement and transparency in their water quality initiatives, ensuring that they remain a trusted provider of safe, clean, and high-quality drinking water in South Africa.
