Rotational Molding

Rochester
Rotational Molding, Inc. is a manufacturer of "high quality"
advanced plastic products and solutions, using the rotational
molding process. Our newest lines of proprietary products
consist of an innovative and advanced line of polyethylene septic
and pump tank products. This product line, designed for the
customer, offers market changing features, advantages, and benefits. |
 |
Water Tightness - The benefits of a "high quality" rotational
molded tank, is a true non-permeable water- tight product, unlike
other construction methods, materials, or aggregates.
|
One-piece and Seamless
- An advantage of "high quality" rotational molding is the
ability to produce tanks without a "mid" or "upper" seam (two
piece construction) which eliminates the threat of leaks, cracks,
and water infiltration.
|
Material Resistance -
Using a "high quality" material in construction can produce a tank
that is resistant to decay or corrosion due to the chemicals or
gases that are present in the soils, waste, or treatment processes
of wastewater.
|
Structural Strength Design -
This innovative septic and pump tank design, offers strong rib design
coupled with superior support column* technology to produce the
industries premier on-site wastewater tank. No longer do you
need to deal with deformation in the man-ways, end-walls, tops, or
bottoms.
|
|

|
Anti-Flotation
Assistance - Molded-Through columns offer temporary relief of
hydrostatic pressures associated with high water table areas.
Once backfilled the support column* technology helps keep the tank
from shifting during the installation process. |
| |
|
Lightweight -
Reduce cost in heavy equipment, manpower, and job completion.
Why pay to wait, when you can set everything yourself? Especially
beneficial in those hard to reach locations. |
| |
|

|
Lifting Lugs -
offers additional ease in handling for all moving and installation
procedures |
 |
Low Profile Design - The
advantages of a low-profile design are significant in many regions
throughout the country where rock, water tables, or soil conditions
limit your ability or desire to install the traditional septic tank |

Why RRM Tanks
|
Across much
of the United States the movement of wastewater lift stations or pumping
tanks has become a growing trend. In recognizing this movement RRM
would like to introduce our advanced line of pump and lift station
tanks. These products are manufactured as a "Heavy Duty" version
of our existing line of tanks. They are an excellent source for
pump tank or lift station projects.

Installation Instructions
-
Measure and excavate hole for proper sizing and to be sure the hole
follows the curvature of the tank. The bottom of the hole must be
level and undisturbed. If rock or potentially sharp objects are
present at the bottom of the hole, provide a 6- 8 inch base of pea
gravel. Never place tank directly on sharp objects or rocks.
However is there is a good, level, undisturbed base this may not be
necessary.
-
Place tank into hole using lifting lugs at each end of tank, or manually
set the tank by hand. It is not necessary or recommended to use
manhole opening or inlet and outlet piping to lift tank into place.
Level tank with carpenter or laser level.
-
The maximum factory recommended burial depth for septic tanks is 24" from
tank top to surface grade. Pump tanks are recommended to be
installed at similar depths but may be buried at a depth not to exceed
48 inches.
-
Begin backfilling columns with either pea gravel or sand if present.
Excavated aggregates may be used so long as the material is loose and
can avoid the common voids associated with heavy clay materials. If
water is present directly beneath tank bottom place bucket gently on top
of the tank while filling tank with water to offset hydrostatic
pressures. If high water may be a continual threat it is then
recommended that pea gravel or sand is used in backfilling columns.
Re-level tank if necessary.
-
Begin backfilling around the tank; continue to compact aggregate around
tank to eliminate voids within backfilling material. Filling the
tank with water during this process is not required as long as water is
not present beneath the tank, and extremely heavy clays are not being
used as backfill material.
-
Once the tank has been completely backfilled it is suggested to fill tank
with water, if high water tables or heavy soil conditions exist.
This process is beneficial in allowing the product and soils to begin
settling into place. It is also advantageous for those unexpected
rainfalls that may hit prior to tank settling.
-
The act of filling that tank with water in good site conditions to
eliminate deformation of the tank is not necessary.
-
Pump tank installation should follow similar procedures, however it is
acknowledged by the manufacturer that the tank will not remain at full
capacity for extended periods of time and as long as the appropriate
minimum liquid depth should range between 6-18 inches.

Norwesco and Snyder Plastic Septic
Tanks
A
New Concept In Tanks
For many years,
rotational molding has proven to be the ideal method of producing a
seamless, one-piece tank that minimizes the risk of leaking.
Polyethylene, because of its excellent corrosion resistance and
chemical compatibility, is the ideal material for onsite septic and
water storage applications. When properly molded, polyethylene can
readily endure the stresses imposed by installation and burial
loads.
Snyder tanks offered by
Hancor are the best performing on-site septic and water storage
tanks available in the marketplace. Preview the following
product list to see why Snyder tanks are the growing choice for all
on-site septic and water storage applications. |
