Markham Municipal Water Company and CDC
- Why is my water usage so high? The reading may be incorrect - meter numbers can be misread or transposed. Alternatively, you might have an undetected leaky toilet or faucet. Contact our office and we'll help resolve the issue.
- What should I do about low water pressure? First, examine your meter and surrounding area for potential leaks. Then call our office to report the pressure issue in your location.
- Why does my tap water appear cloudy sometimes? This cloudy or milky appearance typically clears within seconds. This occurs because water in pipes is under greater pressure than in your glass, causing tiny air bubbles. Cold water holds more dissolved air than warm water, especially in winter when water warms during its journey to your tap. The air bubbles rise and dissipate naturally when pressure is released. Simply let the water sit in an open container until clear.
- What substances are added to our water? We only use chemicals certified by the National Safety Foundation specifically for municipal water treatment.
- Is my water safe if it tastes or smells unusual? State regulations require all public water systems to maintain minimum chlorine levels of 0.2 mg/L (measured at line endpoints). Systems using chloramine must maintain 0.5 mg/L per federal standards. We test disinfectant levels daily to ensure safety.
- Why do particles appear when running hot water? Your water heater likely needs flushing. CAUTION: Most manufacturers recommend professional service. If attempting yourself, carefully review the owner's manual to prevent injury or damage.
- Why do I have a previous balance when I sent payment? We may have received it after the due date or perhaps not at all. Contact our office for assistance resolving this issue.
