Understanding Contaminants in Borehole Water
Borehole water may contain a variety of harmful contaminants. These can compromise your health, plumbing, and appliance functionality. Proper filtration is essential for ensuring clean, safe water. This is especially true in regions like Cape Town and Johannesburg, where specific issues are more common.
Bacteria
One of the most pressing dangers in borehole water is bacteria. According to the World Health Organization, pathogens like E. coli and Salmonella can lead to serious gastrointestinal illnesses. These are especially concerning in areas without regular water testing or disinfection protocols.
✅ Solution: UV sterilizers, ozone generators, and ultra-filters are highly effective in eliminating harmful bacteria. This makes water safe for drinking and cooking.
Heavy Metals: Iron, Manganese, and More
Presence of heavy metals, especially iron and manganese, is a common challenge in borehole water. These minerals can cause serious practical problems such as:
Staining walls, plumbing fixtures, and laundry with reddish-brown or black marks
Turning pools brown and causing unpleasant odors
Clogging irrigation systems and pipes, reducing water flow and damaging equipment
Iron and manganese may not pose immediate health risks at low levels. However, they can severely impact the usability and appearance of your water supply.
✅ Solution: Our filtration systems include specialized iron and manganese removal filters. They are designed to protect your home, plumbing, and irrigation systems while improving water clarity and taste.
Chlorine and Other Chemicals
While not naturally present in borehole water, some users pre-treat with chlorine. This can react with organic material to form harmful byproducts like trihalomethanes. These can cause skin irritation, respiratory issues, and long-term health risks.
✅ Solution: Activated carbon filters remove chlorine and its byproducts while improving taste and smell.
Sodium & Chloride in Coastal Areas (e.g., Cape Town)
Coastal cities like Cape Town often struggle with elevated sodium and chloride levels. This is due to saltwater intrusion into borehole water. It not only makes water taste salty but can also corrode metal fixtures.
✅ Solution: Our custom filtration systems with reverse osmosis remove excess salts. This makes water palatable and safe for long-term use.
Hardness in Borehole Water (e.g., Johannesburg)
Inland areas such as Johannesburg and Gauteng often deal with hard water—high in calcium and magnesium. This causes:
Limescale buildup in kettles and pipes
Ineffectiveness of soap due to mineral content
Dry skin, hair, and spotted glassware
✅ Solution: We offer water softeners and hardness filters. These protect your plumbing and improve daily comfort.
Problematic Effects of Untreated Borehole Water
Just because borehole water looks clear doesn’t mean it’s clean or safe to drink. Many harmful contaminants—such as bacteria, heavy metals, and chemical residues—are completely invisible to the naked eye. Using untreated borehole water can lead to serious issues affecting both your health and your home:
Health risks from pathogens like E. coli or elevated levels of iron and manganese
Appliance damage from mineral buildup, especially in washing machines, geysers, and dishwashers
Costly plumbing repairs due to blocked irrigation lines and corroded pipes
Unpleasant smells and tastes, such as a metallic flavor or a rotten egg odor (often caused by sulfur or bacteria)
If you’ve noticed stains on walls or fixtures, brown discoloration in your pool, reduced water pressure, scale buildup on appliances, or unpleasant odors, it’s a strong sign that your borehole water is compromised. It requires proper filtration.
✅ The solution? Installing a professionally designed water filtration system improves water quality instantly. This protects your family, your appliances, and your peace of mind.
How We Solve Water Quality Issues
At The Water Solar Company, we create effective solutions to improve your water quality.
Reverse Osmosis
Reverse osmosis is one of the most effective methods of purification. This technology pushes water through special membranes, filtering out 95-99% of contaminants, including bacteria and heavy metals.
Many homeowners using borehole water find that this system significantly improves the safety and taste of their drinking water.
UV Sterilizers
UV sterilization uses ultraviolet light to kill up to 99.9% of microorganisms. It works exceptionally well alongside other filtration methods. This ensures complete disinfection without harmful chemicals.
One family installing a UV sterilizer noticed a dramatic decrease in gastrointestinal issues among their children. This provided peace of mind about their water supply.
Ozone Water Treatment
Ozone treatment is a powerful, chemical-free method for purifying water. It oxidizes metals like iron and manganese. This reduces staining and scale—and eliminates bacteria, viruses, and unpleasant odors. Ozone treatment is ideal for borehole systems. It ensures your water is clean, safe, and fresh without leaving any residue.
Carbon Filters
Carbon filters remove chlorine, sediment, and unpleasant tastes through activated charcoal. When combined with reverse osmosis or UV sterilizers, carbon filters can greatly enhance water quality.
A customer reported that switching to a carbon-filtered system completely transformed their kitchen water experience, making it cleaner and more flavorful.
Solar-Compatible Systems
In sun-rich South Africa, solar-powered filtration systems represent an eco-friendly and economical choice. These systems reduce reliance on traditional electricity. This can lead to substantial savings on energy bills.
A coffee shop owner found that investing in solar-compatible filtration allowed them to cut costs while promoting a sustainable approach to business.
