Heavy-Duty Black Water Septic Holding Tanks (600L to 2500L)
Ditch the fragile, thin-walled wastewater containers that crack under ground pressure. These heavy-duty black water septic holding tanks are engineered for serious commercial and agricultural applications, providing rugged, long-lasting waste containment for remote job sites, off-grid homesteads, and rural RV parks lacking municipal sewage access. Constructed with impact-resistant reinforced walls ranging up to 7.0 mm (0.28") thick, these tanks safely contain raw sewage, chemical fertilizers, and harvested rainwater without leaking or degrading. Shipped compact for easy freight transport, we stock these commercial-grade septic systems at wholesale prices to ensure you get real value for the dollar on your heavy infrastructure projects.
Key Features:
- Heavy-Duty Reinforced Walls: Built with ultra-thick walls (up to 7.0 mm (0.28")) that easily withstand heavy ground pressure, extreme weather, and chemical exposure without buckling.
- Chemical & Weather Resistant: The industrial-grade black composite safely stores caustic black water sewage, agricultural fertilizers, and rainwater while blocking algae growth.
- Expandable Height System: Optional heightened barrels can be bolted onto the top ports to increase vertical capacity while maintaining the original tank footprint.
- Multiple Capacity Options: Ranging from a compact 600 L (158.5 Gal) system for remote cabins up to a massive 2500 L (660.4 Gal) tank for high-volume commercial waste containment.

GREAT for small mouths!
Color: Microbrush Kit, Color: Microbrush Kit
The Pet toothbrush from Jasper is the perfect toothbrush for tiny mouths. I have two cats one that is under 10 lbs and one that is 17 lbs. This toothbrush works best for both of them! It is great to find a toothbrush that comes with multiple heads to use with my multiple cats! The handle is curved so it allows me to get into those hard to reach places which cats sometimes struggle to let you reach. The toothbrush was easy to use, and both of my cats had no problem with getting their teeth and gums cleaned. I also enjoyed that the brush heads are replaceable so one toothbrush handle can last a very long time! This starter pack is the perfect product to use when starting to brush their teeth. As the toothbrush is small, the bristles are gentle and the cat can chew on the toothbrush without them instantly destroying it. The toothbrush also holds onto the "toothpaste" product very well. There were not spills during the toothbrushing process. I definitely approved of this product and will continue to support this product in the future.

Great for cats, get rid of lip lifter!
Color: Microbrush Kit
The best toothbrush for cats! It fits and is easy to maneuver, and because it’s small, my cat doesn’t mind the shape. The only thing is that the lip lifter hits teeth and gets caught in cheeks, so I sanded that off, which has made teeth brushing much easier.

Soft brush, good quality!
Color: Microbrush Kit
I like that the bristles on the brush are very soft and it's curved well for my kitty's mouth. The only thing that I don't care for is the handle is pretty long and doesn't need to be.

Best best pet toothbrush I have tried
Color: Microbrush Kit
This is by far the best toothbrush I have found for my cat. It was clearly designed by someone who deeply understands feline dental health. The way the bristles decrease toward the tip and the specialized part for lifting the corner of the mouth are incredibly thoughtful and effective features. While the bristles are soft, they are strong enough to provide the necessary pressure against the teeth. My cat has a relatively small head and mouth, yet she resisted this brush the least of all. I will not be going back to my previous toothbrushes. Very highly recommended!

Cat approves, easy to use, comfortable to grip, sturdy.
Color: Microbrush Kit, Color: Microbrush Kit
My cat seems to love it so that's a automatic win! I was a little unsure about using a long handled toothbrush, I thought it would be more difficult to use but turns out its actually easier than the little finger brushes. The heads on the toothbrushes can be swapped, making it so that you dont have to buy a whole new one. It's been a few months since I bought it and its holding up well, no major wear on it aside from some gnaw marks from my Chonk chewing on it. Fits nicely in my hand and the brush head isn't too big for my cats tiny faces & teeth. I'd recommend it so far and I'm going to keep on with this brush instead of trying a new product every time.
