Alkaline Water Systems in Durham, NC
Durham Water Management serves Lake Michie and Little River water at 4 to 7 grains per gallon hardness with monochloramine disinfection. Chapel Hill and Carrboro receive OWASA water from Lake Jordan. Both utility water sources benefit from an alkaline RO system that removes chloramines, lead, and trace contaminants at the drinking water tap, then adds calcium and magnesium back through a remineralization stage for clean, pH balanced drinking water at 8.0 to 9.5. Aquafeel Solutions Carolina is a veteran-owned, NSF certified installer serving Durham, Chapel Hill, Carrboro, and Orange County. Free in home water test. BBB A+ since 2018. 25-year warranty.
Durham and Triangle Water: Two Utilities, One Alkaline Solution
The Durham-Chapel Hill market is served by two distinct utilities with meaningfully different source water. Durham Water Management draws from Lake Michie and Little River Reservoir, both Neuse River watershed tributaries. Hardness typically tests at 4 to 7 grains per gallon. Disinfection uses monochloramine year-round, which provides long-lasting protection in Durham's extended distribution network but leaves a chemical bite that many residents notice, particularly those who brew coffee or tea at home.
Orange Water and Sewer Authority (OWASA) serves Chapel Hill, Carrboro, and the University of North Carolina campus from University Lake and Cane Creek Reservoir (Jordan Lake watershed). OWASA water is somewhat softer than Durham's, typically 3 to 5 GPG, with a slightly different mineral profile. OWASA also uses chloramine disinfection. An alkaline RO system installed in Chapel Hill performs the same function as in Durham: the RO membrane strips the chloramines and any trace contaminants, the remineralization stage adds back beneficial minerals.
For residents in the Durham-Chapel Hill research triangle corridor, including Duke University area, Southpoint, East Durham, and Hillsborough, the common complaint we hear at Aquafeel is the chloramine taste combined with concern about whether city water has been adequately monitored for emerging contaminants. Both Durham and OWASA publish detailed Consumer Confidence Reports, and both consistently meet EPA standards. Still, meeting regulatory minimums and delivering water you would choose to drink are different standards, and alkaline RO is the gap between them.
What a Free Water Test Reveals in Durham Homes
Our WQA-certified technicians carry portable water testing equipment that measures pH, hardness, chloramine concentration, iron, TDS (total dissolved solids), and several other parameters on-site. For Durham homes specifically, we frequently see:
- Hardness at 4 to 7 GPG from the Lake Michie source
- Chloramine concentration in the 1.5 to 3.5 mg/L range (utility target is 2.0 to 4.0 mg/L)
- pH in the 7.4 to 8.2 range at the tap (adjusted upward to reduce lead pipe corrosion)
- Elevated lead readings in older Durham neighborhoods with pre-1986 plumbing
- Occasional iron from aging distribution infrastructure in established neighborhoods
The free test takes 30 to 45 minutes and gives you lab-grade numbers at your specific tap, not citywide averages. This is important because older homes in Watts-Hillandale, Old West Durham, and Burch Avenue neighborhoods can have legacy lead solder in the plumbing even when the utility water itself is lead-free. The RO membrane removes lead regardless of whether it originates from the source water or the premise plumbing.
What Science Actually Says About Alkaline Water Benefits
The research community is cautious about broad alkaline water health claims, and so are we. Mayo Clinic and Cleveland Clinic both note that the evidence for general anti aging, immune boosting, and cancer-prevention claims is not scientifically established. We do not market our alkaline RO systems on the basis of unverified health claims.
What peer reviewed studies do support: limited clinical evidence that alkaline water may reduce acid reflux symptoms in some patients, and associations between higher alkaline mineral intake and bone density in postmenopausal women (verify with the NIH study database). Discuss any health-specific decisions with your physician.
What is definitively true: alkaline RO water is free of chloramines, lead, PFAS, and other tap contaminants, and it tastes significantly better than untreated city water at the tap. For most Durham homeowners, improved taste and contaminant removal are reason enough. The alkaline pH is a bonus.

Frequently Asked Questions
Where does Durham get its drinking water?
Durham Water Management draws primarily from Lake Michie on the Flat River and Little River Reservoir in northern Durham County. Both are Neuse River watershed sources. Water runs at 4 to 7 GPG hardness with monochloramine disinfection. An alkaline RO removes the chloramine taste and trace contaminants while adding beneficial minerals back.
Does Durham water have PFAS contamination?
Durham's Lake Michie and Little River sources are upstream of the major Cape Fear PFAS discharge zones. Durham Water Management tests for PFAS and publishes annual results. Levels have been within EPA guidelines, but the 2024 EPA MCL of 4 parts per trillion is stringent. An NSF 58 certified RO membrane removes PFAS to below detection limits regardless of source levels.
What is the difference between alkaline water and regular RO water?
Standard RO water is purified but slightly acidic and mineral-free, giving it a flat taste. Alkaline RO adds a remineralization stage after the membrane that dissolves calcium and magnesium back in, raising the pH to 8.0 to 9.5. The result tastes similar to premium spring water while retaining the contaminant removal of RO.
Do you serve Chapel Hill and Carrboro as well as Durham?
Yes. We serve all of Durham, Chapel Hill, Carrboro, Hillsborough, Mebane, and surrounding communities. Chapel Hill and Carrboro receive OWASA water from Lake Jordan, a different utility with its own chemistry. Our free in home test measures your specific tap water regardless of which utility supplies you.
