What BIG BLUE can do for you
The CWE-1500A “BIG BLUE” aerobic treatment system is an alternative to a problematic septic tank featuring a state-of-the-art design for domestic wastewater treatment. Utilizing the extended aeration process, the BIG BLUE plant provides pretreatment, aeration, clarification within a single sealed fiberglass tank. There are no mechanical components located within the tank. All mechanical components are located above the ground surface for easy maintenance. The BIG BLUE plant does not utilize gadgets or proprietary equipment to treat the wastewater which results in simpler operation, more consistent treatment along with lower maintenance requirements.
Engineered for residential wastewater flows up to 1,500 gallons per day, BIG BLUE is a great option for houses, camp grounds, RV parks or other non-industrial applications. Sold exclusively by Clear Water Supply, each BIG BLUE system tank is manufactured and installed under our close supervision and collaboration with our partners.
A great value
The BIG BLUE aerobic treatment system is a great value. It is priced far below most all other comparable systems on the market. Furthermore, the BIG BLUE system uses less mechanical equipment and therefore requires less maintenance than other systems. When maintenance is required, the equipment is above the ground surface and does not necessitate entry into the treatment tank. The parts used to maintain the system are inexpensive and easy to replace.
With no motors or pumps required, operation costs are limited to electricity for the air compressors. Clear Water Supply also offers solar powered systems for those who want a self-sufficient or “off the grid” system.
We call it big but it is actually compact in size
The BIG BLUE aerobic treatment system is small enough to fit in a standard 9′ x 18′ parking space.

Low profile
The BIG BLUE aerobic treatment system is is a quiet on-site aerobic wastewater treatment system. It has a low odor profile using activated carbon air filters which are easy to replace without opening the tank. The BIG BLUE tank is installed underground with access port openings being 6” above finished grade. A small air supply compressor less than 3’ high can be placed in a shed, shelter or out in the elements.
Easy maintenance
One issue with onsite residential aerobic wastewater treatment systems is maintenance. Most systems use pumps, mixers, filters and a lot of mechanical equipment in their tanks. The BIG BLUE aerobic wastewater treatment system was designed to be easy to maintain. All system mechanical equipment can be serviced without accessing the inside of the tank. All equipment inside the tank requires little to no maintenance. The equipment is non-proprietary and replacement parts are available either from us or on the open market.
Longevity
BIG BLUE is built to function for a long, long time. The aerobic treatment tank is built to NSF 61 standards by a licensed facility out of gel-coated fiberglass. This provides a corrosion-proof long-lasting tank that requires no maintenance or sealing. The components in the tank are corrosion proof or corrosion resistant and have no moving parts.
Flexibility
We can provide the treatment system can be provided as stand-alone or in conjunction with lift stations, additional treatment equipment like flow equalization, disinfection, filters and leech field equipment.
Design support
We offer the treatment system as “equipment only” or provide assistance with permitting and design support as your application requires for an additional fee.
