Southland Organics PORT is a powerful liquid formula that provides rapid waste degradation and odor control for a portable, vault, and pit-type toilets as well as RV and Marine holding tank applications.

PORT efficiently and effectively breaks down waste in tanks 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.

Digests Difficult Compounds

Southland Organics Port contains a synergistic blend of new bacterial strains which have been scientifically developed (selectively adapted) to cope with difficult compounds and chemicals present in wastewater effluent. Unlike any other bio-formulation, Port contains bacterial strains that will digest difficult and non-biodegradable compounds such as detergents, paper, oil, grease, hydrocarbons, and phenols.

Amazing Odor Control

Southland Organics Port bio-formulation provides exceptional results controlling hydrogen sulfide and other mercaptan odors emitted from portable toilets and holding tanks. Our substrate is a new and novel, totally organic product that controls sulfide odors by blocking the pathways of sulfide-producing compounds. The product is also unique in that it contains micro- and macro-nutrients that accelerate microbial activity, growth and performance.

Safe for the Environment

Southland Organics Port is all natural and organic, so it is very beneficial to the environment.

Multiple Uses

It can dissolve grease and eliminate odors in grease traps, wastewater lift stations, and RV dump stations. When diluted 1:7 with water in a backpack sprayer, it can be used to solve any biological odor including garbage dumpsters, organic spills, and animal decomposition. For septic tanks with a drain field, we recommend 8 ounces of Port monthly in a 500-gallon septic tank for routine maintenance. For problematic systems, 1 gallon of Port monthly in a 500-gallon tank will resolve most issues within a couple of applications. Port can completely clear a clogged septic system drain field.
