Who publishes this guide

Collin Water Guide is published by North Texas Water Solutions LLC, a Plano water treatment company. North Texas Water Solutions appears on this site as a featured listing, labeled every time it appears. Every other company is listed for free, did not pay for placement, and was included because it met the criteria below.

How the list was built

1. Search. In October 2026 we searched Google Maps for water filtration, water softener, whole-house filter, reverse osmosis, water treatment and plumber-softener terms in Frisco, Plano, Allen and McKinney, which returned 161 unique listings.
2. Filter. We removed retailers, grocery and bottled-water stores, utilities, businesses outside DFW, closed businesses, listings without a website, and 16 listings that appeared to be lead-generation pages rather than real local companies.
3. Verify. We read each remaining company's website and kept only those that describe installing whole-home filtration, water softeners or reverse osmosis for homes, which left 43 companies.
4. Enrich. Services, brands, license numbers, founding year and social profiles come from each company's own website. Ratings and review counts come from its public Google Business Profile.
5. Order. Companies with dedicated whole-home filtration pages and a broader water treatment service list appear first, then companies ranked by Google rating and review volume. The order isn't an endorsement.
