Find the Right Plastic Tank for your Needs

Premier Plastics Inc. manufactures CSA / NSF certified polyethylene water and septic tanks in a wide range of styles and sizes for you to choose from. To help you find what plastic tank suits your needs, we have outlined some basic points to consider when making a decision.
If there is something you are not sure about, ask a Premier Plastics Expert.

ABOVE GROUND OR BELOW GROUND

Will the tank be placed above ground or be buried? Tanks for burial are ribbed or shaped to resist the pressure from the ground around it. Underground tanks are rated by the maximum depth of earth cover allowed over the top. Lightweight fill such as styrofoam boards of bark mulch could be used if the required depth is over the maximum (consult our factory).
The level of ground water, frost line, depth of bedrock, and backhoe access are also considerations when installing tanks underground. Above ground tanks are designed to withstand the pressure from the water sitting inside the tank.
Poly tanks must always be vented to atmosphere.

SIZE OF TANK

Your actual tank size will be based on:

  • Usage needs per day or month for household, gardening, car washing etc.
  • Source of water and reliability of supply i.e. from rainwater, creek, well, water district or truck. The longer the period with no or reduced supply, the larger the tank must be to serve your needs during these times.
  • The best location and space available for your tank. Also, how will you get the tank into place? Polyethylene tanks are bulky but are relatively light weight. As a very rough guide, for the purpose of handling, polyethylene tanks weigh approx. 0.2 lbs. per gallon depending on size. Do you have vehicular or marine access, steep slopes, planted areas, trees, pathways or outbuildings to consider?
  • Your BUDGET. Can you plan on leave room for future expansion?
  • The size of your home if you need a septic tank. Septic tanks in British Columbia are sized primarily by the number of bedrooms. Sizing in other jurisdictions may be by the number of bathrooms or number of people. A State or Provincially registered sanitarian, registered on- site wastewater professional or your local environmental health authority should be consulted when planning onsite sewage systems.

STYLE OF TANK

Each style of tank has its own best suited application:

VW_250

VERTICAL WATER TANKS
These tanks are vertical cylindrical in profile and are also the most commonly installed in the market place. Generally, these are the most economical in terms of dollars per gallon.

 

 

Box_400BOX TANKS
These tanks are for spaces with limited headroom such as crawlspaces and under decks. The low profile also allows moving into place through narrow openings. In tight spaces a floor panel could be installed above access lids. The tanks are designed to lay flat and not be placed on their side unless properly braced against bulging. Consult the factory if this is your only option.

 

TT-1400TAPER TANKS
Used for applications that require completely open top access, such as fish rearing or chemical mixing. The tapered side allows multiple tanks to nest together for shipping economy.

 

SL_340SLIMLINE TANKS
A specialized tank for very narrow vertical spaces (18” or 22” wide) or when clearance in front of the tank is limited. The ‘holes’ in the design prevent the sides from bulging when filled.

 

RAINDROP TANKS
A slim, low profile tank for low headroom or narrow spaces –inside or outside space. Will pass through a 36”’ wide doorway. Uses include storage and re-pressurization of water supply from low yielding wells to regain flow rate during periods of peak demand during the day, rain water harvesting, and for standby storage to suppress small fires.

 

 

CONE BOTTOM TANKS
Designed for sediment collection or granular material. The tanks require a steel/fiberglass floor stand for support.

 

 

LT130LEG TANKS
Leg tanks can provide the maximum storage volume in a rectangular low headroom space. They are also a convenient way to transport water by pickup truck or trailer from a public utility. Uses include spraying, pressure washing or portable fire suppression. The smaller sizes can be positioned crossways in a truck box to leave room for other equipment or supplies. Keep in mind the weight of the water you are transporting and the hazardous effect of water moving around a partially filled tank.

 

UT_35_100UTILITY TANKS
Utility tanks are vertical cylindrical in profile and are specifically designed for 30” or 36” door opening access. The larger sizes are used for standby fire suppression where there is no municipal supply.

 

CIS-500CISTERN TANKS
These are tanks installed below ground for water storage. There are a number of styles and sizes. These are SuperTanks, Saturna Tanks, Fat Albert Tanks, Submarine and Moonlander styles. Check the maximum bury depth for each size.

 

STS-900DSEPTIC TANKS
These tanks are designed for partial or below ground installation. Styles according to size are SuperTanks and Saturna Tanks. Styles of septic pump out tanks and trash tanks are SuperTanks, Saturna Tanks, Fat Albert Tanks, Submarine Tanks and Moonlander Tanks. Gravity powered septic ‘FLOUT’ dosing packages are installed in four sizes of heavy duty Leg Tanks. Check the maximum bury depth before making your selection.

 

TANK COLOUR

Colour is used for esthetic or identification purposes. Vertical water tanks are either black or dark green. Some sizes are available in either colour. When used outside these colours are less noticeable and limit sunlight penetration. The natural polyethylene we use has a built in ultra-violet light stabilizer against sunlight. Most, smaller tank sizes are natural white. Typically underground water tanks (cisterns) are blue, septic tanks are yellow. All pigments used (except yellow) are CSA/NSF certified for drinking water.
