Hi Jim,
I left you a message on your voice mail earlier today. I wanted to discuss a unique situation we have
at Big Mountain Ranch. The OWTS was installed and inspected in 2018. We made a slight
modification to the system in 2019, and at that time discovered some groundwater in the
trenches. With the poor soils and up gradient drainage, the contractor and civil engineer have
agreed that an interceptor drain up gradient of the STA is appropriate to divert water around the
STA.
I have documented the entire installation and the pump was recently started up by Valley Precast, so
the system is functional and ready for use. We are waiting on the completion of the interceptor drain
design and installation will take place prior to winter.
There is no reason the system cannot be utilized at this point. We will be finalizing our final
documentation once the interceptor drain is installed. I hope this helps with allowing occupancy of
the residence.
Please let me know if you have any questions. I have attached our design that accommodated the
7th bedroom and the installation observation documents we put together in September.
Thank you!
