Water Filtration & Treatment in Coral Springs

Four providers, one city

The City of Coral Springs' Water Districts page shows a map of the four service areas and lists each provider's contact:

• City of Coral Springs Water District, 9500 W Sample Road, billing 954-344-1825; water plant 954-345-2160.
• Coral Springs Improvement District, 10300 NW 11th Manor, 954-753-0380.
• North Springs Improvement District, 9700 NW 52nd Street, 954-752-0400.
• Royal Waterworks, 8900 NW 44th Court, 866-753-8292.

Your water bill names your provider. If you are not sure, the city's map is the quickest check. The City also reports emergency interconnections with the other three providers and with Margate and Coconut Creek.

How each provider treats its water

Details from each provider's most recent report we reviewed:

• City of Coral Springs: groundwater from the Biscayne Aquifer, pumped from 18 production wells as deep as 145 feet, goes through conventional lime softening, which the city says removes or lowers iron, hardness and organics, then filtration and disinfection.
• CSID: water from 11 Biscayne Aquifer wells goes through a low-pressure reverse osmosis plant that CSID has run for over 10 years. About 10 to 15 percent bypasses the membranes and is blended back to raise alkalinity and hardness to desirable levels.
• NSID: draws from the Biscayne Aquifer and the brackish Floridan Aquifer through 11 raw water wells. In 2023 it expanded its nanofiltration plant and added reverse osmosis, with capacity of 10 million gallons a day.
• Royal Waterworks: a separate provider; check its own annual report for source and treatment.

Chloramine across the city

The City's 2025 report lists "chlorine and chloramines" at an average of 2.7 ppm (range 0.8 to 3.6). CSID's 2024 report lists chloramines at 2.9 ppm (1.5 to 3.3), and NSID's 2024 report lists chloramines at 3.66 ppm. All are under the 4.0 maximum. Each July, all four providers temporarily change their chlorination method; in 2026 that ran from July 13 to 27, with hydrant flushing during the day.

That chloramine residual is what most households notice. See the chlorine and chloramine filter page for Coral Springs.

What fits a Coral Springs home

• House on any provider: a whole-home city water system for chloramine at every tap, often with RO in the kitchen.
• Townhome or condo: an under-sink alkaline RO for drinking and cooking water. See the drinking water system guide.
• Spots and scale: on CSID or NSID membrane-treated water, hardness is often low; test before buying a softener. See hard water spots and softener vs. filter.
• Business: an ion-exchange softening plant for equipment where the test justifies it.
• Irrigation or private well: see well water treatment in Coral Springs and orange and rust stains.

Fluoride and PFAS, briefly

The providers' recent reports list fluoride results from before July 1, 2025, when Florida law ended added fluoride in public water. On PFAS, NSID reported no detectable PFAS in its 2023 UCMR5 sampling, while the City's 2025 report lists several PFAS compounds in its unregulated contaminants table.

What filtration is, and is not, for

Each provider reports that its water meets federal and state requirements. Home treatment does not replace that; it lets you choose how your water tastes, smells and behaves at home. For any specific contaminant, a system must be certified for it under the relevant NSF/ANSI standard, so check the exact model's listing. Comfort issues like dry skin after showering and odors like a rotten-egg smell have their own pages.
