SANS 241-SA’s standard for drinking water quality

SANS 241 is South Africa’s national standard for drinking water quality, setting the legal limits that any water used for drinking, cooking, or bathing must meet. It covers microbiological risks like E. coli and coliforms (with zero tolerance for pathogens), chemical risks such as lead, arsenic, nitrates, fluoride and free chlorine, physical and aesthetic factors like colour, odour and total dissolved solids, and operational indicators such as turbidity and pH. It applies to municipalities, commercial properties, mines, and any business supplying water to staff or the public — making compliance a legal requirement, not just good practice. Crystal Clear can help you.

Restaurants & Food Outlets

Clear Water. Clean Kitchen. Compliant Business.

Every dish you serve starts with water — and in South Africa, that water is legally your responsibility. Under SANS 241 and food-safety regulation, any water used for cooking, washing produce, ice, or utensil cleaning must be free of pathogens and within strict chemical and physical limits. One failed municipal supply test or environmental health inspection can shut your kitchen down.

Hospitals & Healthcare Facilities

Water You Can Trust, Where It Matters Most.

In a healthcare setting, water isn’t a convenience — it’s a clinical safety issue. Wards, sluice rooms, kitchens and staff areas all depend on water that meets SANS 241 standards, with zero tolerance for E. coli and coliforms, and tight limits on turbidity and chemical contaminants. For facilities drawing on boreholes or supplementary sources under the National Water Act, quality control becomes even more critical — and even more visible during infection-control audits.

NanoKleen® gives hospitals and clinics an added layer of protection. Our nano-fibre filtration removes practically all viruses, bacteria, heavy metals and pharmaceutical metabolites — without electricity, chemical dosing, or the maintenance burden of complex treatment plant. It’s a straightforward, dependable safeguard for wards, staff kitchens, and patient-facing water points.

  • Supports infection-prevention and SANS 241 water-quality goals
  • No electricity dependency — reliable even during power interruptions
  • Simple maintenance — filter change only every 400–2000 litres
  • SABS-confirmed >99.99% bacteria removal

Hotels & Hospitality

Guest Safety Starts With What Comes Out of the Tap.

Guests trust that the water in their room, at breakfast, and in the ice bucket is safe — and under SANS 241, that trust is also a legal obligation. Hotels drawing on boreholes, JoJo tanks or backup supply must additionally consider National Water Act registration and quality requirements, on top of standard municipal compliance and tourism-grading water-safety expectations.

NanoKleen® protects your guests and your rating. Our nano-fibre purifier delivers consistently clear, great-tasting water without electricity, chemicals, or wastewater discharge — ideal for guest floors, kitchens, spas and back-of-house use, especially where municipal supply is inconsistent or where boreholes supplement the mains.

  • Clear, safe water that supports SANS 241 compliance
  • No power required — resilient during outages and load-shedding
  • Chemical-free, low-maintenance operation
  • Backed by SABS testing — a genuine guest-safety talking point

Give every guest water they can trust, from check-in to check-out. Bring NanoKleen into your property.
