Septic Tanks

Vault Toilets

Add 2.5 gallons of PORT and 15 gallons of water per 1,000 gallon vault as needed. During increased traffic, add 1 gallon of PORT between cleanouts or as needed.

Optimally Port (diluted in water as specified below) should be added when the vault has been freshly pumped. The vault can then be left to fill to capacity without any additional product being needed. Additional water may be needed if solids begin to exceed the water line.

Vault Size Dosage Water to Add
3000 gallons 7 gallons PORT at least 49 gallons
2000 gallons 5 gallons PORT at least 35 gallons

PORT efficiently and effectively breaks down waste in your septic tank and clears bio-solids. In septic tanks with a drain field, PORT breaks down solids and opens up drain lines, potentially adding years between septic tank pumpings.

PORT is one of the best septic tank treatments out there because it makes use of beneficial bacteria to break down solid waste so that no harsh chemical additives are necessary.

The active beneficial bacteria cultures in PORT septic tank treatment are capable of breaking down human waste, toilet paper, household waste from the garbage disposal, feminine hygiene products and other solid waste. When used as regular maintenance for a septic tank, PORT can provide a healthy bacterial ecosystem that ensures your septic system works smoothly year-round.

Your septic tank works through a simple digestion process. Natural bacteria in human waste and other solids creates a sludge layer in your septic tank. Anaerobic septic systems, if left without a septic treatment, can be problematic because this sludge can build up and cause clogs. Aerobic bacteria in PORT break down the scum layer created by anaerobic bacteria, clearing out the septic tank of too many solids and ensuring the septic system is functioning properly.

PORT septic tank treatments is great for any size tank. It can work on smaller tanks too. You can just adjust the amount you pour down your drain to get the correct dose. Likewise, you can increase the dose for a larger septic tank size.

PORT septic tank treatments contains a synergistic blend of scientifically selected bacteria cultures (selectively adapted) to cope with difficult compounds and harmful chemicals present in wastewater effluent. Unlike other septic tank treatments’ bio-formulation, PORT contains live bacteria that will digest difficult and non-biodegradable compounds such as detergents, paper, oil, grease, hydrocarbons and phenols. PORT can dissolve solids and digest grease, and unlike most treatments is powered by active bacteria that clears your home plumbing lines.

No more DIY hydrogen peroxide solutions to toilet paper buildup. Some folks like to use organic solvents and inorganic acids as septic treatments, but PORT is a much more innovative, simple and safe solution. Our septic treatment product has active bacteria cultures that can reduce solids with just one monthly dose.

Apartment Plumbing Problems

Southland Organics waste management products leverage our three core features to eliminate odors and break down solids and sludge in tanks, vaults and pits.

Beneficial Microbes

The added beneficial microbes in PORT help decompose waste without harming the environment. This active, aerobic microbiology works against anaerobic bactria in tanks to clear solids and eliminate odors. Microbes amplify conventional programs by making your inputs work harder for longer.  

Organic Acids

Organic acids and top-quality, organic carbon work to break surface tension in tanks, thus eliminating biofilm buildup. Tanks, vaults and pits can function without getting clogged or developing strong odors.

Active Carbon

Carbon has three main functions in terms of waste management. It binds hydrogen sulfide, which eliminates odors caused by decomposing organic matter. Adding carbon to a tank, vault, or pit increases the carbin to nitrogen ratio, which speeds up the composting process. Finally, carbon feeds the microorganisms that break down solids, helping them break down faster.

With these three secret ingredients, tanks, vaults and pits can function better, require fewer pumps and resist odor development- All without harming the environment!
