1.4. Product Requirements: The Contractor shall use a live vegetative consortium that utilizes bacteria that thrive in both aerobic and anaerobic conditions. The material shall have a minimum of 12 strains of bacteria (Including the species: aerobic; Pseudomonas putida, Pseudomonas fluorescens Bacillus subtilis, facultative anaerobic; Bacillus licheniformis- facultative anaerobic bacteria; Bacillus thuringiensis- facultative anaerobic bacteria, Bacillus megaterium, Bacillus pumilus, Bacillus amiloliquefaciens) that digest food sources and turn them into water and CO2, and which will generate more bacteria. The bacteria must be capable of working as soon as they enter the wastewater/sanitary sewer system. Specifically, the bacterial consortium must be capable of carrying out beta-oxidation to prevent the buildup of free fatty acids, which are the major contributor of drain line blockages. The bacteria strains shall contain no chemicals, surfactants or free enzymes. The bacteria strains shall be guaranteed to contain no Salmonella, E-coli O157:H7, or Listeria. The material supplied by the Contractor must meet and is certified under the USDA BioPreferred® program. The bacterial consortium shall be naturally occurring bacteria that has not been genetically altered, genetically engineered or genetically modified; meet Biosafety Level 1 criteria; and degrade carbohydrates, proteins and FOG (animal, plant and cooking).

1.4.1. Contractor shall furnish, update and maintain one each CHEMSEARCH Bio Amp programs or equal. Salient Characteristics: An automated, patented biological delivery system that produces live bacteria to digest fats, oils, and grease (FOG) in wastewater systems. It starts with a dry bacterial culture and, over 24 hours, automatically grows trillions of live bacteria, which are then dosed into drain lines to reduce grease buildup, eliminate odors and backups, and replace harsh chemicals like acids and caustics. Installation is in lift station 3001 wet well.

Dimensions: H 29.25”, W 18.50”, D 9.25” / Door front clearance - 26.0” Painted metal cabinet with locked door - 16-gauge steel 24VAC circulating pump and valves Hopper and Feeder mechanism (ABS material for tablet dosing) Polypropylene growth vessel Control panel with software programming Potable water 1” air gap interconnecting piping for water supply and drain connections. Designed for wall mounted with supplied hanging bracket and under counter operations. A technician will perform monthly routine maintenance inspections, replace FREE- Flow microbes as needed, clean equipment/ machine, responsible for troubleshooting and repair equipment failures at no cost to the government.

1.4.2. Contractor shall furnish, install and maintain 24 gallons of CHEMSEARCH Pit Boss Product Code 10035862 or equal. Salient Characteristics: A bacterial agent designed to interact with waste to accelerate aerobic digestion, break down solids, and reduce gas production in manure. For the initial dosing to liquefy, de-grease for good flow in lift station 292 wet well. A technician will perform monthly routine maintenance inspections and apply by hand 2.4 gallons of Pit Boss monthly to maintain good flow when needed.

1.4.3. The contractor shall furnish, install and maintain four CHEMSEARCH Eco Storm systems or equal. Salient Characteristics: Dimensions H 13”, W 5”, D 5”, Weight 2 lbs, Batteries 4, 1.5V “C” cell batteries, Operating Temperatures Max: 30°C, Min: 5°C. Installation Requirements: Ensure the unit can be mounted in an accessible position above the height of the required discharge location. The unit dispenses via the built in pump and the unit can pump up to 6’. Protection from precipitation, water spray or excessively humid conditions. It’s an environmentally friendly system that uses patented bacteria to biologically degrade organic waste and fats, oils, and grease (FOG) in drain lines. It features a battery-operated BIO-Amp dispenser that automatically applies billions of bacteria, preventing clogs, foul odors, and pathogen growth without requiring electricity or a water line. This solution helps maintain drain lines, reduces maintenance costs, and creates a more sanitary environment with required 100 billion microbes (natural bacteria) to break down greases, fats, oils, and human waste in lift station 585 wet well.

Additionally, the contractor shall do a treatment of odor shock treatment as needed. Contractor shall furnish and install odor punch (50 gallons) applied by auto dosing along with drain mate. A technician shall perform monthly routine maintenance inspections, replace chemical as needed, and clean equipment / machine. The contractor is responsible for troubleshooting and repairing equipment failures at no cost to the government.

1.4.4. Contractor shall furnish, install and maintain three CHEMSEARCH Eco Storm systems or equal with required 100 billion microbes (natural bacteria) to break down greases, fats and oils, in facilities 1257, 1992 and 1990 (one per facility).
