SYSTEM DESIGN
FOR FTC HOMES
OF LOT 7, BLOCK 1, SHADOWOOD FARM
ORONO, MINNESOTA
3-31-94
Information follows for a pressure mound system for a four bedroom
house proposed on the above property. All construction and mater-
ials must be in accordance with MPCA Chapter 7080 and City of Orono
codes.
All construction traffic must be kept off the primary and the alt-
ernate septic areas. These areas should be marked off prior to
construction.
A pumping tank will be needed to house the pump necessary for
pressure distribution to the system. The manifold and supply line
pipe must be constrr-:ted to drain back to the pumping tank.
A weather proof enciosure will be needed for the controls and
switches for the pump and a warning light/sound system will be
needed to warn of pump failure.
If any other information is needed, please contact me.
Sincerely,
PERCOR, INC.
