FEATURES
GP 210 is a complete unit, including grinder pump,
check valve, tank and all necessary controls built
l into a single unit, ready to connect.
All solids are ground to a particle size so fine as to
pass easily through the pump, check valve and small
diameter pipe lines ... even objects which should
not be in sewage (plastic, rubber, fiber, wood, etc.).
The 11/4 inch discharge connection can be adapted
to any piping materials which meets local code
requirements.
A corrosion resistant tank of fiberglass reinforced
polyester (FRP), sized on the basis of computer
studies of wastewater usage patterns, provides
"peak flow" holding capacity.
An integral check valve assembly in the GP is
custom designed for non -clog, trouble -free
operation.
The GP is automatically activated and, because
it runs infrequently and for very short periods, it's
annual electric energy consumption is typically
only half that of a black and white TV.
It is available with an integral fiberglass accessway
for burial ranges from 14 inches to 10 feet.

RE: Subdivision Plan Comments - The Summit, Section 5B
Frederick County, Virginia
Dear Mr. Lellock:
Upon review of the subject subdivision plan, we offer the following comments:
1) It will be necessary to submit an engineered grading plan at the time of the building
permit application process for the following lots: 1226 - 1247 and 1205 - 1214.
The subject site plans should entail basement and finished floor elevations,
proposed grading, driveway location and culvert sizes. It will be necessary to
submit a certified as -built to the public works department prior to obtaining a final
certificate of occupancy. This certified as -built shall indicate finished floor
elevations as well as pertinent drainage features and verify that the final lot grading
conditions and building elevations meet the intent of the approved site grading
plan.
2) In accordance with VESCH Standard 3.18, provide outlet protection dimensions
on the plan for all proposed culverts located under Waterside Lane. In addition, it
will be necessary to provide a stabilized outfall channel from the culverts to the
water surface of the lake. The channel shall be designed for a ten (10) - year storm
event (i.e., quantity and velocity).
3) It will be necessary to submit a certified as -built plan to this office which reflects
all improvements performed along Waterside Lane.
