T.G. Rankin Co. is proud of its long tradition of pursuing clean water and environmental issues through continued support and development of wastewater, pumping, treatment and dispersal technologies
Poly Septic Tanks
Polyethylene Septic Tanks out perform concrete in crack and leak resistance. Once the rainy day choice, Poly Tanks comply with codes in most counties. Fast pick-up and delivery. Poly tanks can be loaded and handled by two people. Just put it into a pick-up truck and take it to the installation site on your schedule. No need to wait for concrete septic tank delivery. With Poly tanks there is less need to cut down precious trees to make way for a boom truck. Distributors throughout the Midwest stock tanks in several sizes and styles with risers, covers and effluent filters. Contact usfor the location of a distributor near you.
Secondary Treatment and Effluent Dispersal
Often in today’s residential home construction market pumping wastewater to municipal treatment is cost prohibitive. Our wastewater division’s leading technologies include; Peat Filtration of effluent, Drip Dispersal, Sand Filters, new installer access box (right), Fixed Film Media Aeration, UV disinfection and Automated FOG (fats, oils and grease) monitoring. We offer localized onsite wastewater treatment for residential subdivisions and commercial applications. We specialize in projects where great distances from municipal sewers prevent pumping and where adverse soils make conventional wastewater treatment impossible. Flow rates from 350 to 3-million GPD.
Aero-TechAerobic Treatment unit. Used in conjunction with a solids settling tank (conventional septic tank) Aero-tech AT-500 features a 5-year warranty on its air pump. Aero Tech does not use a typically problematic air compressor as do most other units. The Aero-Tech Model AT-500 is an extended aeration, activated sludge process. In the activated sludge process, microorganisms remove soluble contaminants from the wastewater, utilizing them as sources of energy for growth and production of new microorganisms. Exceeds NSF40 and will meet or exceed future, more stringent output criteria.
Lasaire Waste Lagoon Technologies
For new installations, Lasaire permits smaller pond footprint. Lasaire high efficiency waste lagoon rehabilitation systems. Defers sludge removal 10-20 years in most cases through added aeration and agitation. BOD reduction.

Pumping To Treatment
Grinder Pumps and Systems
When pumping sewage or effluent is required we offer everything necessary to complete the job. For pressure sewer applications grinders are the pump of choice. We have several. If looking for a replacement pump or if you are designing a subdivision of 300-homes we have the exact the pump or lift station system for the application. When solids are separated and only effluent needs to be moved to treatment we offer several effluent pumps for standard, filtered and high head applications.Contact usfor design assistance.
Wavin, Flow-Liner polypropylene sewer line inspection / access chambers allow cleaning inspection, sampling and rehabilitation. Flow-Liner inspection ports are a cost-effective, easy to install sewer access point. They are especially useful at the outlet of a grease trap to allow accurate DOH, EPA, and DNR compliant sampling
Tegra 600 and 1000 Poly Manhole replacement. Corrosion resistant and light weight. Easy installation for problem applications. Contact usfor design assistance.
SJE Rhombus IFS Model TD ( Timed Dosing ) Pump Control Panel
Model TD control panel is an installer friendly, reliable means of controlling one singe phase effluent pump in on-site septic installations. Time dosing prevents soil or system overload.
A low-level cutout float overrides the timer to prevent the pump from running dry. An alarm float activates the audio/visual alarm system indicating a high liquid level. Common applications include sand filter systems, pressure distribution systems, mound systems, drip systems or any application requiring timed dose control. UL/cUL Listed.
Product features:10" X 8" X 4" enclosure, alarm beacon / horn, silencer switch, programmable timer, pump circuit breaker, magnetic motor contactor, control and alarm fuses, terminal blocks, Switches: HOA, one (low-level cutout) 20’ PumpMaster; one (alarm) 20’ Sensor Float® Mini control.
SJE Rhombus was a pioneer in time dosing to prevent the overload of drain field soils. They offer a wide variety of Liquid Level Sensing, Flow Control, Monitoring and Alarm Systems. Pump Starters, Custom Panels, Alternators for duplex sewage ejector systems, Hydro Pneumatic Controls, Electrode Alarms, Tel-A-Signal Systems and Panels to Print. We can provide switches or panels one at a time or quantities and packaging for your most demanding OEM applications.

Polylok Extend & Lok
This problem solving PVC pipe fitting was designed for easier septic filter Installation in hard to reach places. No more fighting with outlet pipes that are flush against the septic tank wall. Simply hammer in the PVC friction fit Extend & Lok™ and that’s it! The filter or inlet tee now can easily be installed and centered under the riser. Extend & Lok™ Makes for Easy Installation on existing systems. Many other uses too!
