Industrial Water


Analysis of Industrial water includes but is not only limited to wastewater. WearCheck Laboratories offer a variety of packages to determine water quality and functional use within the industrial space. 

We provide you with preselected packages and tailored options, to fully analyse you industrial water for cooling systems, corrosion, boiler water, bacterial growth, wash bays and so much more.  


Determination of Cooling Systems water quality is essential in the functionality and safety of the system. Our package includes: Alkalinity (Total or M) as CaCO3, Ammonia, Total Hardness, Chloride, Fluorides, Nitrate-Nitrite, Ortho Phosphate, Total Suspended Solids (TSS), Calcium, Magnesium, Zinc, Iron, Silicon Dioxide, Copper, Nickel, Lead and Biological Oxygen Demand.


Cooling tower water systems are an ideal environment for the growth of many types of bacteria, including Legionella. Every cooling tower should be monitored by routine sampling and testing for the presence of bacteria, both general (aerobic) bacterial species and Legionella bacteria.

Dip slides are sufficient for daily monitoring but a quarterly full suite bacterial analysis should be done to ensure safety.


General caution - clear water may be heavily contaminated with bacteria.


Our Corrosion Control Package analyses the waters' corrosive determinands, ellowing for the implementation of treatment measures and reducing long-term repairs and maintenance costs.


Our Corrosion Control Package includes: pH, Conductivity, Total Alkalinity, Chlorides, Suphate, Total Dissolved Solids, Total Suspended Solids, Langelier Saturation Index, Temperature, Calcium, Magnesium, Zinc, Iron, Silicon Dioxide, Copper, Nickel, Lead, Biological Oxygen Demand 

Surface/Irrigation/Ground/Additional water


Irrigation, agricultural, water supply, river and pool etc. analysis is conducted following recommended parameters for required water (drinking, irrigation etc.). 


Irrigation and agricultural water analysis is conducted to ensure the preservation of soil fertility and recommended to follow GAP requirements. Water that does not fall within the GAP requirements can negatively impact the soil ecosystem as well as plant growth. These analysis consists of, but are not limited to; Sodium Absorption ratio, pH, minerals, conductivity, Manganese (Mg), Potassium (K), Calcium (Ca), and Sodium (Na), as per GAP standards 

River, lake and dam water analysis is conducted following National Water Act standards.

Pool and Spa water analysis is measured but, is not limited to; pH, chlorine, Total Alkalinity and Calcium Hardness. Cyanuric Acid levels should be tested for in outdoor pools which use chlorine.

Our Cape Town Laboratory offers Sea Water Analysis, to determine metals, ions, contamination and more 


Ground and borehole water can contain varying levels of contaminants. Microbes, metals and minerals play a role in the everyday water supply. 


While your water is clear, water analysis may reveal potentially harmful contaminants that would otherwise remain undetected. Bacteria are found in all-natural water systems. Most are harmless but, some can pose health risks. Corrosive elements found in water can damage plumbing as well as appliances, shortening their lifespan. Salts and metals found in water may be harmful. Natural leaching of pesticides and agricultural waste can contaminate underground systems 


Ground and borehole water analysis are required as groundwater can be contaminated by leaching of agricultural waste, leaking sewage and lines and natural geological systems. Borehole and groundwater analysis is conducted per compliance with client requirements; 


  • Drinking water analysis – SANS 241:2015, recommended testing to be done seasonally or during high rainfall seasons as water table levels change.

Monitoring an engine’s cooling system performance is imperative, as research shows that 40% to 60% of all diesel engine failures are caused by a faulty cooling system. Therefore, a key factor in avoiding dreaded premature engine failure is to keep the cooling system operating optimally by using the most appropriate coolant and regularly measuring its chemical and physical properties.


Without proper maintenance, cooling systems can lead to failure modes such as overheating, overcooling, pitting, cavitation erosion, cracked heads, piston seizures, reduced critical clearances, low oil viscosity, increased wear and plugged radiators.


The effects of these problems manifest as:

• Acid/alkalinity balance (corrosion)

• Scale and deposit formation (blockages)

• Electrolytic corrosion (electrolysis)

• Cavitation erosion (liner pitting)

• Galvanic corrosion

• Additive loss

• Aeration (erosion)

• Rust


The longer a particular coolant remains in an engine, the greater the probability of these problems occurring. With increased coolant service life, therefore, the need for regular coolant monitoring increases.


WearCheck has devised a set of tests to determine whether the coolant is in good condition and capable of doing its job. If any of the pre-determined parameters are found to be out of the recommended range, then remedial action can be taken to ensure the healthy, normal operation of the cooling system and, in turn, the engine.
