Fiberglass Tanks

We sell fiberglass tanks with capacities from 50 gallons to 15,000 gallons and we can custom-make tanks up to a whopping 57,000 gallons.  (Because the smaller fiberglass tanks are expensive for their size, we recommend a polyethylene tank for situations requiring a 4,000-gallon capacity tank or less.) 

Our tanks are made with USDA approved food-grade polyester resin and gel-coated on the exterior for long life.  Standard tanks come in shades of gray and don’t need to be painted (but can be with proper primer and high-grade latex paint.)   Or you can dabble in exterior decorating and have your tank custom-colored—purple, pink, yellow, anything-- for an additional cost of around $700 for a 10,000-gallon tank.



All tanks listed are vertical, flat bottomed and domed top.  For a reasonable additional cost, the tanks can be constructed with flat tops or thickened for partial burial.  For a lot more money, we can make you a tank that can be completely buried. (The standard tanks can be buried up to two feet deep without thickening the walls at all provided they are buried in well-drained soils that aren’t prone to shifting.  In other words, clay is out and just forget it in places with a high water table, like Houston.)  Tanks come with three threaded female half-coupling fittings—anywhere you want, any size you want—as well as a vent hole at the top and a 18-inch manway with cover.  The fittings are an integral part of the tank.  Why is this important?  They CAN’T leak!

Delivery to our Austin/ Dripping Springs area is $620 for tanks up to 12 feet in diameter, $850 for anything larger. Tricky deliveries (hoisting the tank over the house with a crane truck, for instance) are priced on an individual basis. Prices subject to change without notice.

The Booley Eliminator

This simple but hard-working fellow is a Tank Town exclusive that will eliminate the need for a roofwasher filter, eliminate the time it takes to clean those roofwasher filters, and eliminate the accumulation of organic gunk in your storage tank. Instead of filtering the water, the Eliminator captures a metered wash of rainwater—the first, dirtiest wash--before it can enter the storage tank.  Because we know that water, especially rainwater, is precious, the amount of water you capture is adjustable, depending on roof size, your particular conditions (i.e. lots of trees overhanging the roof vs. no trees overhanging the roof), and even seasonal variable. (Lots of oak pollen vs. no oak pollen.)

Large Eliminator:  550 gal
Price:  $1250.

Smaller Eliminator:  200 gal
Price:  $1150, installed $1250.

Roof Washers

Our roofwashers are made by Water Filtration Company, constructed of
fiberglass, and include either one or two 60 micron filters. They attach at the
inlet of your tanks, prefiltering the water before it enters the tank. If you have a limited drop from your lowest downspout to the inlet of the tank, you might have to go with a horizontal roofwasher, which is one where—duh—the filter is
mounted horizontally. This allows the inlet and outlet of the roofwasher to be nearly parallel.  But it also means that the filter is more difficult to remove and replace during cleaning.

(Remember:  These roof washers require vigilant maintenance.  If their filters become clogged--and they will if you don’t clean them regularly--it will restrict your flow so greatly that water will be trickling into your tanks and gushing out the top of your roof washer during a downpour. This is the voice of experience warning you about this.) In the other style of roofwasher, where the inlet is 10 inches higher than the outlet, the filter sits vertically. This style also comes in a larger, two filter size.

Additional Filters:  $53.00, shipping not included.

Floating Cistern Filter Kit

To use one of these beauties you’ll need to order your fiberglass tank with a full-through coupling .  Filters dirt and debris down to 60 microns and draws the water from 12 to 16” below the surface,  where you’ll find the cleanest water in any body of water. Keeping this filter clean is crucial. $425 for kit. It’s a good idea to buy an extra filter so you can swap them out when it’s cleaning day and hose out the dirty filter at the car wash so it’s ready to go when you need it. Replacement filter element: $37.

Handy Dandy Pump/Disinfection/Filtration Board

This little ensemble hooks up in a snap and is all you need to pump, filter, and disinfect a whole house water supply. The setup includes a Grundfos MQ water supply pump, a pressure gauge, two ball valves, a clear and an opaque filter housing with 5-micron sediment and 3-micron activated carbon filter, and a 12gpm Sanitron ultraviolet light.  It's all plumbed together and mounted on a sturdy plywood-and-galvanized-steel panel. (Read on to find out more about the individual components.) Price: $1950.

1" inlet from tank 1" outlet to house Produces 17gpm The 3 micron filter reduces flow to 9gpm. Uses standard filters 3"x10".

Pumps

1hp Grundfos:  $575.

We have become quite fond of the Grundfos MQ water supply system.  This diminutive gizmo combines a pump, motor, pressure tank and controller into one integral unit.  (Yep, that means you don’t need an additional pressure tank.)  It’s also expressly approved for use with rainwater.  The pump is self priming, has a check valve incorporated in the suction port, and features a user-friendly control panel.  Best of all, it comes with a built-in overtemperature and dry-running protection. 1hp. 1000 watts or 9 AMPS 17gpm 55psi constant

Filters:  Housings and Cartridges

Most of our systems use two inline filters.  The first filter housing is clear and holds a 5 micron cartridge filter which should be changed every month.   The second filter housing is opaque and holds a 3-micron activated charcoal filter which should be changed around every three months.

Clear Housing:  $40.

Opaque Housing:  $35.

Hanging Brackets:  $4 each

Wrenches:  $5 each

Replacement O-rings (nearly everyone unwittingly throws one of these away at least once when changing the filter cartridges and then start screaming when the housing leaks like a sieve when the system is fired up again.) $3.00 each.

5 micron filters:  $3.50 each

Activated charcoal filter: $10.00 each

1 micron filter:  $4.50 each

......................................................................................................................................

Filter Assembly

This is a dual filter assembly that includes a clear housing, an opaque housing, two ball valves so you can change the filter cartridges without getting soaked, and, best of all, two pressure gauges. Why two? One measures the pressure of incoming water  and the other measures the pressure of the outgoing water. By monitoring the pressure differences, you'll know, without a doubt,  when to change  your filters.  3/4" inlet 3/4" outlet $325.

Ultra Violet Light

We carry Atlantic UV lights which meet or exceed all the U.S. Public Health Service Criteria.  While Atlantic offers a variety of models that can handle anywhere from two to 416 gallons per minute, we’ve found that the S37B, which handles 12 gpm, is the ideal size for most personal rainwater collection systems.  The cartridge filters—which you should use inline prior to UV disinfection—restrict the flow from the jet pump to well below this 12 gpm limit.

Maintenance on the units includes manually cleaning the quartz sleeve once a month or so and replacing the lamp after 10,000 hours (approximately 14 months of continuous use).  Use .58 amps or 46 watts

S37B Sanitron:  can also handle 12 gpm and is very easy to clean.  The additional cost of this unit is often offset by money you save by not having to buy a new sleeve after you break it:  $875.00

Replacement bulbs for 12 gpm: $75
Replacement bulbs for 20 gpm: $95
Replacement sleeves: $80
Transformers: $87
End connectors: $25 per set
