Western Water Associates

What Western Water Associates does

Western Water Associates, Inc. is a privately held, Aptos, California-based HVAC water treatment company serving commercial, industrial, institutional, and government customers across the Western US and Pacific regions, with worldwide availability for corrosion studies and consultations. The firm's core technology portfolio covers liquid and solid chemistry treatments, non-chemical electronic field treatment (Griswold WAVE), custom chemical formulation (ChemDraft), and an EPA-registered drain pan biocide (ANTI-CLOG® #1) — the only product EPA-permitted to claim Legionnaires' Disease Bacteria kill efficacy. The company distributes equipment from 13+ manufacturers including PulsaFeeder, LMI, Griswold Water Systems, and WalChem, bundling chemicals, hardware, and field services into integrated treatment programs.

The business operates a hybrid revenue model combining one-time chemical and equipment sales, recurring weekly or monthly maintenance contracts, project-based new construction services (specification writing, LEED evaluation, equipment sizing, startup), and fee-based custom formulation commissions. Technical sales representatives work directly with facility engineers across 16 industry verticals (Healthcare, Data Center, Food and Beverage, Military, University, District Heating, etc.), supported by an in-house laboratory for water and deposit analysis. GTM motion is enterprise field sales with inside-sales support via phone, email, and the corporate website.

The firm has operated for 30+ years (firmographics state a 2003 founding date for Western Water Associates, Inc., with "30+ years of specialty HVAC wet side experience" cumulative), employs 1-10 people, and holds Certified Small Business (CA and Federal), MBE, WBE, and DVBE-partnered certifications enabling procurement set-aside access. Headcount is small relative to revenue potential, and the company has no disclosed funding rounds, parent entity, or acquisition history; ownership appears founder/management-owned.
