In your letter to Trinity American Corporation, Permit # WQ0014756 dated May 7, 2021,
you requested a Plan of Action to be submitted to you within 120 days.
The problem to this point has been excessive water use, stemming from lavatories and/or
toilets left running, resulting in thousands of gallons of water being introduced into the
on -site waste water system. In response, Trinity American Corporation WWTF has
purchased two YdroStop Automatic Water Shut -Off Valves. These valves utilize both
differential pressure sensing and timer operation to detect continued water flow. In the
event of a large leak, the water supply will be shut-off the instantly. If a small leak is
detected, like a toilet left running, the unit will shut-off the water supply in 15 minutes,
limiting the leak to tens of gallons, instead of thousands.
These units are scheduled for installation as soon as possible. We believe this will
eliminate excess water from the system, and keep the daily average flow within permit
specifications.
Thank You,
