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.

Game changer for me
Scent: Unscented-4.23OZ
I don't review stuff... I just don't. But this is the best face cream I've ever used. Fine lines are going away. I'm a senior and I've tried oils, creams, sooo many face products. This is a game changer for me. My skin just drinks it up. I don't expect to look 20 again, I just want to look my best for my age. I've been using this product 2 weeks. I think my skin is looking like it did 10 years ago. I'll take it! It absorbs great. My skin does not look or feel oily like so many other products made my skin. Can't express how much I love this stuff!

This product is the real deal.
Scent: Unscented - Jojoba Oil
OMG. This is the best skin care product I have ever used. I'm 61 years old and my skin was showing sun damage, dark circles, real wrinkles around my eyes, lips, and forehead. Basically, I was looking every bit of my 61 years.
About 30 days ago I started using this organic beef tallow with raw honey moisturizer in conjunction with a product to clear the pores on my nose. (That's a different review.) I will never go back to the 5, costly products I was using.
I was using a daytime moisturizer with SPF, a dark circle cream, a dark spot remover, a fine line product, and a night time resurfacing cream before trying this product.
That was a couple hundred dollars every 5 weeks or so.
Since starting this beef tallow and raw honey 30 days ago, my skin looks 10 times better. It's dewy but not greasy. My makeup looks good ALL day. My wrinkles are less noticeable and, I think, reduced in depth. My under eyes look so good. No more concealer under my foundation. In fact, I can go out and about with no makeup now!
This product glides on easily, no dragging or pulling. It never feels greasy. And it only takes about a marble sized amount for my full face, neck, and decolletage.
I use it morning and at night. So far, the little jar is still 3/4 full.
Amazing product. I will be buying more for sure.
Oh, one more thing. About 2.5 years ago, I had to have a mass removed from the left side of my neck. The scar was very noticeable. This cream is even improving that!
Try it. See if I'm wrong!
