Dear [BLANK HERE]
This letter is to confirm the fact that the three [BLANK HERE] wastewater treatment units your firm installed at Butterfield Park in Corona since Jun, 1976 have been working satisfactorily with very little maintenance and service.
The [BLANK HERE] units are connected to the public bathrooms and snack shop facility. The [BLANK HERE] units have been serviced by Mr. Mark Buhler and Mr. Al Jackson of our staff after instructions by you after the time of installation.
If we can be of further help to you, please contact either of us at the above telephone.
Signed Al Jackson, Park Supervisor
