SEPTIC TANKS

Den Hartog Industries low-profile septic tanks
Low-profile septic tanks from Den Hartog Industries are designed to provide safe and durable storage. The tanks are furnished with multiple fitting locations for a variety of plumbing configurations and two openings for buried lids or access/inspection risers. They are available with one or two compartments, with capacities of 1,000, 1,200 or 1,500 gallons. They may be backfilled empty and have sectional ribbing designed to sustain vertical soil pressures of up to 500 psf at a maximum soil depth of 36 inches. 712-752-8432; www.denhartogindustries.com.

Front Range Precast Concrete watertight tanks
Watertight tanks from Front Range Precast Concrete include permanently attached anti-buoyancy collars that guarantee the tanks won’t float. All tanks have uniform, heavy reinforcement and use a monolithic process, meaning there are no seams in the tank — top to bottom. They are in conformance with ASTM C1227. To ensure watertightness, the inner core mold is released by means of compressed air. If there are holes or cracks, the tank will not come off the mold. Tanks also go through a hydrostatic testing procedure. 800-783-3207; www.flxx.com.

Infiltrator Water Technologies IM-Series Tanks
Injection-molded IM-Series Tanks from Infiltrator Water Technologies are available in multiple sizes including the IM-540 pump tank, IM-1060 and large-capacity IM-1530 septic tank. Lightweight, strong and watertight, the tanks enable shallow, multiple and serial tank installation options in septic and pump applications. All have integral heavy-duty lids that interconnect with the watertight click-and-lock EZsnap riser. The tanks also have structurally reinforced access ports, reinforced structural ribbing and fiberglass support posts to provide additional strength. The two-piece tank design nests for efficient shipping, and inboard lifting lugs make delivery and handling easier. The tanks frequently house advanced wastewater treatment systems such as the ECOPOD fixed-film bioreactor system or the ECOFILTER pump vault tank filtration system. 800-221-4436; www.infiltratorwater.com.

Features include CSA, NSF and IAPMO certification, a COEX-4 multilayer co-extrusion process, a low-profile design that means less digging and avoidance of a high water table, lightweight construction, a multiport inlet/outlet that’s convenient for field piping, the ability to enter and exit the tank on the ends or sides, two 24-inch manways to provide easy access for maintenance and service, a cylindrical shape that requires no water for backfill, a threaded riser system and watertight, seamless construction. 866-943-7256; www.rothmultitank.com.

LIDS

BrenLin Seal-R
Seal-R septic tank lids from BrenLin create a strong seal between the septic tank and the riser, eliminating water infiltration between the tank and riser. They are made of durable materials, range from 12 to 42 inches and can be personalized with a service provider’s company information. The 42-inch lid meets growing demand for bigger risers to accommodate new technology. 888-606-1998; www.seal-r.com.

Fergus Power Pump Duel Power Lid
Duel Power Lids for septic tank installations or restorations from Fergus Power Pump are designed for new installations or to complete restoration projects by replacing a concrete lid. The lid is designed like the rafters in a house to provide structural durability and support a heavy wheel load without adding weight to the lid. The top is slightly domed to meet compliance throughout the U.S. Lids can be insulated with an R-value of 6 and are available in 18-, 24-, 30- and 36-inch sizes. 218-736-6772; www.ferguspowerpump.com.

Hedstrom Environmental septic lids
Hedstrom Environmental septic lids are designed to eliminate riser systems. They are offered in 18- and 24-inch lids and adapter plates that are retrofit for standard corrugated I.D. drainpipe. The square-to-round adapter plate allows for quick conversions of tank risers to corrugated pipe. They are rotationally molded for strength with UV inhibitors to protect against color fade. Lids can be standard, foam-filled or sand-filled for additional strength. A gasket and safety screws are standard, along with optional custom nameplates displaying your company name and phone number. Safety nets are available upon request. 888-434-5891; www.hedstromenvironmental.com. 

Orenco Systems DuraFiber Lids
Orenco Systems 24-inch DuraFiber Lids are made of resin-infused fiberglass fabrics for durability and damage resistance, with breaking strengths in excess of 20,000 pounds. They fit most ribbed PVC and HDPE riser pipe and weigh only 11 pounds. Lids have a flat-style flange, allowing flush-to-grade installation; a cored centering ring, providing an easily aligned, snug fit; and a urethane gasket, helping form a watertight seal. Lids include four 5/16-inch stainless steel flathead screws and a hex wrench. Optional insulation (2 or 4 inch) is available, which can be preinstalled at the factory or installed on site with a hardware kit. The lids have a nonskid surface with customizable center insert (for logos, etc.), along with a molded-in caution statement. In addition to the standard green color, they’re available in three landscape patterns — grass, river rock and bark — to blend into surroundings. 800-348-9843; www.orenco.com.

RISERS

Polylok Universal Safety Screens
Septic tank Universal Safety Screens from Polylok work with the company’s 12-, 20- and 24-inch risers. The 24-inch unit works with PVC ribbed pipe, HDPE corrugated pipe and concrete risers. The Lid-Lok safety device works with the company’s 20- and 24-inch riser covers. When used with the 20-inch Dual Safety Cover for a 24-inch riser pan, the secondary safety devices can help prevent accidents. 877-765-9565; www.polylok.com.

TUF-TITE tank risers
Tank risers from TUF-TITE have internal supports or ledges to reinforce internal plastic safety lids. The ledges will strengthen the company’s plastic internal safety lids or a variety of internal safety devices made by others, such as concrete, fiberglass or rope netting. The riser lids come with the necessary mounting hardware, including safety screws. 800-382-7009; www.tuf-tite.com.

SEPTIC FILTERS

BioMicrobics SaniTEE
SaniTEE effluent screening devices from BioMicrobics protect absorption areas from premature clogging and failure due to the release of nonsettleable solids and/or nondegradable flushed materials from the septic tank. Available in 4-, 8- and 16-inch-diameter sizes, the unit installs directly in the outlet tee of the tank. Its keyhole weirs provide consistency of flow despite surges. The angled slots resist blinding and prevent clogs inside the filter housing to extend the life of the system, reduce clogging material and improve flow conditions. It has easy slip-in installation and comes standard with a swabbing feature for clean-in-place maintenance. 800-753-3278; www.biomicrobics.com.

Clarus Environmental WW4
The WW4 effluent filter from Clarus Environmental is mounted in the outflow of the septic tank to provide protection from solids moving out of the tank and into the dispersal area. A secondary screen provides continued protection during servicing. When the primary cartridge is removed to be cleaned, the secondary screen blocks solids from sloughing off and traveling to the dispersal area. After the primary cartridge is cleaned, the secondary screen can be removed and cleaned. It can handle up to 4,000 gpd and can be assembled on site in a multifilter configuration for larger flows. 800-928-7867; www.clarusenvironmental.com.

Sim/Tech Filter STF-100A2
The STF-100A2 pressure filter from Sim/Tech Filter helps maintain proper and efficient year-round operation of mounds, sand filters and other pressurized distribution systems. The low-headloss (0.21 psi) pressure filter mounts on the discharge side of an effluent pump, acting as a last line of defense to prevent plugged holes and reduce effluent TSS. This mounting location also extends the time between servicing. The vortex action created by the pump scrubs the screen and the backflow through the filter after the pump shuts off, washing debris out. A single 2-inch filter can handle flow rates up to 83.8 gpm. It can be designed to handle almost any flow rate or load. Larger 3- and 4-inch filters are available. The standard screen filters to 1/16 inch, and optional socks allow for additional filtration to 0.024, 0.007 or 0.004 inch. 888-999-3290; www.simtechfilter.com.
