Built on trust.
Since 1952.
For over 72 years, General Pump Company has been the contractor California’s most critical water systems depend on — when the job has to be done right.
A company built around water — and the people who depend on it.
General Pump Company was founded in 1952 in the San Gabriel Valley. What began as a local water well contractor has grown into one of California’s most trusted pump and well services companies — serving water utilities, municipalities, farms, and industrial facilities across the state.
For more than seven decades we’ve operated with one principle: do the job right, stand behind the work, and treat every water system like it belongs to someone who depends on it. That hasn’t changed.
Today, General Pump Company is a Sylmar Group Company with three full-service shops in San Dimas, Camarillo, and San Bernardino, and a field service fleet ready to deploy across California.
