COLORADO ONLY - Infiltrator chamber septic system leach field installation instructions and pricing. Click here for main septic chapter with details and cost of other system parts.

The Infiltrator chamber septic system leach field differs from conventional leach fields, which use perforated plastic pipes laid in a twelve inch gravel bed. It is not a stretch of the imagination to envision those small holes clogging faster than a three foot wide chamber. That's why only sells the best! Infiltrator chamber leach field units are high-density polyethylene arches that interlock to form a continuous drainage area with a much greater storage 'surge' volume than conventional pipe leach fields. Structurally, chambers will take a heavy load, so you may drive over when necessary, just be sure to drive perpendicular to the chamber (like crossing rail road tracks) and never driving down the length of chambers. Installation simply involves digging a series of three foot wide trenches (or a large rectangular bed as shown below), connecting the Infiltrator chambers, and backfilling with the soil you originally removed. As a general rule, trenches 'fingers' should be no longer than fifty feet (12 or 13 Infiltrators long) for best function and most even effluent distribution. Unless you are installing as a "bed" system (where the chambers are right next to each other), leave at least six feet of undisturbed soil between fingers. In practice, this six feet of undisturbed soil between trenches becomes eight feet or more since you don't want to compact the soil above the Infiltrators; one should allow at least the width of the backhoe between trenches. And don't forget to loosen the soil twelve inches below bottom of the trench (scarify) before installing the Infiltrators leach chambers. The worst mistake you can make is to compact (smear) the soil in bottom of a leach field trench. You want to be sure to loosen the soil to allow for proper percolation of effluent. No gravel is needed - but gravel is always an upgrade option to aid percolation in any soil. No geotextile fabric (weed barrier material) is need - but in sandy and silty soils, it is recommended to cover the tops of your chambers with gravel and then fabric to keep soil from migrating into the chambers and surrounding gravel. For even more protection, fabric can be placed atop the chambers and then covered with 3/4 inch nominal crushed stone and then yet another layer of fabric atop the stone. Over-engineering is excellent insurance for long-term viability. As with most construction projects of this scope, it is always best to do the job right the first time. Regardless of what local Individual Sewage Disposal System ISDS guidelines will allow you install, best practice is to maintain certain high-quality guidelines for the sake of longevity, if nothing else.

Infiltrator® chamber leach field systems are far superior to pipe-in-gravel in every aspect: smaller leach field size due to optimal percolation, increased retention capability for heavy loading days, root infiltration protection for long term viability, and resistance to traffic with 16,000 pounds per axle load rating given at least one foot of cover. Driving over the top of a leach field is not recommended, but you can on occasion, just be sure to drive perpendicular (from the side) not down the length of a run. You don't need to hire an engineer to design your septic system in most counties. We do not supply any engineering services. Local regulatory officials normally allow you to submit a site plan and pull your installation permits as the homeowner-builder as long as the soil percolates well. Then you can save even more money by renting a backhoe and installing your own septic system! Installation is relatively straight-forward, but even seasoned professionals can get too mired in 'how they've always done it' to realize there are better ways to approach any project. We're here to help every step of the way, doing our best to ensure you don't make that one critical mistake, like not venting your leach field properly or not scarifying the base of your trenches. We encourage clients to mail copies of their septic system permit plans for our review after purchasing a system, as there are always details that could use improvement with any plan.

Infiltrator septic chamber leach field installation versus pipe in gravel stone and pipe

How to build it yourself septic leach field design tips and general rules of thumb
* Limit field runs to +/- 12 or 13 chambers which is about 50 feet in total length
* Level runs with a transit - only use a two or four foot level for approximating
* Always bring effluent pipe in top of chamber end cap, never into the bottom
* Install large granite or durable ceramic tile underneath inlet for splash plate
* Always ventilate the ends of every leach field pipe run or set of chambers
* Loosen 'scarify' soil at least one foot in base of trench before backfilling
* Add gravel into base of trench and atop chambers to improve longevity
* Geotextile fabric prevents soil intrusion into gravel from above & sides
* Never install geofabric in the bottom of any trench or septic leach field
* Septic tank up to 10 feet away and leach fields 20+ feet from foundation
* Leach field, especially pipe-in-gravel, should be 20+ feet away from trees
* Never plant bushes or deep-rooting fescue, dichondra, brome, or rye atop
* Never drive over a septic tank or leach field - chambers perpendicular only

Standard Quick4 'Plus' Infiltrator chambers are 34 inch wide (3 foot trench) by one foot tall by four foot long (net length after connecting together) and cost $33 each, $31.50 each for 50 or more, and $30 each for a full pallet load of 85 chambers or more. We offer a 3% cash discount when paid with bank cashier's check or US Postal money order (instead of MasterCard or VISA) and free delivery within about 50 miles of Denver or will-call pickup in person at Denver area warehouse. Rows of Infiltrator are generally limited to 12 or 13 chambers (about 50 foot length) requiring two $20 end caps for each row. Note that the 'plus' series end caps can be installed in the middle of a run to feed both directions (still need one for each end). We offer a 3% cash discount for payment other than credit card (bank wire transfer, bank cashier's check, or US Postal money orders). Please e-mail with a cut-list for your project to get a personal quote. In addition to your parts list, please provide the drop site location and we can confirm free delivery is available in your area. In average soils, budget around $2000 for two bedroom home leach field, $2500 for a three bedroom, and around $3900 for a complete 4 bedroom Infiltrator chamber leach field system by the time you factor in distribution box, pipe, and vent fittings. Total package price depends upon leach field layout (bed versus trench) and number of Infiltrator chambers required, which is not known until you get a soil test and a copy of the local Individual Sewage Disposal System ISDS regulations. Local building code supplies the equation used to calculate leach field size in the ISDS: number of bedrooms multiplied by the factor of percolation rate of the soil with a percentage reduction in size given for using Infiltrator chambers. We can quote the system after you supply us with a cut-list detailing number of chambers and end panels and whatever other fittings you may require, but we do not supply engineering services to determine how many chambers you will need.

Infiltrator Quick4 Plus standard chamber dimensions

All of the various 'gravel-less' leach field chamber system brands function by the same set of physical limitations, regardless of marketing claims. 'Required' installation tips are not to be implied, but there are always 'good, better, best' methods of approaching any construction project. 'Good enough' with chambers is digging a level trench and backfilling atop with native soil. 'Better' is to scarify (loosen and rake) the soil in base of trench to a depth of at least one foot before installing chambers. 'Best practice' is adding a 6 to 8 inch layer of crushed gravel to scarified soil to ensure long-term percolation and best sewage treatment. Some engineers go one step further and lay 2 inch diameter perforated pressurized distribution pipe in the top of chambers with 1/4 inch diameter holes every 2 foot facing upwards to ensure equal effluent introduction throughout the trench. This only works with a lift station 'dosing tank' to send a couple hundred gallons of effluent out at one time. Non-pressurized (no pump or dosing tank) systems do not benefit from distribution pipe since the larger 1/2 inch diameter holes must face downwards and effluent rarely reaches the end of even a short run of chambers. When specified, non-pressurized systems strap 4 inch perforated pipe either side of the structural columns found on Quick4 Plus design. It is not recommended to run distribution pipe along the base of the trench since that area can be flooded at times should percolation rate be slow. Several inches of gravel atop chambers with a layer of geotextile fabric on top and sides is common practice in sandy or silty soils. Best practice is to limit trench lengths to about 50 foot (12 to 13 four foot long chambers) for full trench saturation and best treatment of septic effluent. Always vent the ends of each chamber run to ensure healthy air flow through system.

"Are we allowed to install this septic system on our property" is not a question we can answer for you. We have been providing much the same passive (non electric) septic system parts for over twenty years now, but we do not follow constantly changing city, county, and state building regulations. Unfortunately, with 63 counties in Colorado, regulations changing from year-to-year, and interpretations of those rules varying from one inspector to another, it's never possible to say for certain 'what is allowed' locally. Your local county building department is your primary source of information on what is possible to install according to local 'code'. Rather than telephone them with questions, you should drive over in person and get a copy of their local Individual Sewage Disposal System ISDS Regs and also get a list of locally licensed soil engineers. The building department will confirm or revise your site plans once submitted for approval. Often the county inspector will assist you with site plans and design as a service provided for their permit filing fee. If not, they will refer you to a local engineering firm that can visit the property in person and design the system. We provide free consultation after the sale on installation procedures, system design improvements, and operational issues, but we do not provide any soil testing, on-site services, 'stamped' engineered plans, or 'advanced treatment' systems.

Flow director splitter valves are far superior to distribution boxes or splitting effluent flow with a tee fitting manifold. Effluent flow can be split 50/50 evenly between the two outlet lines OR alternate the flow 100% to one side or the other. This allows one half of your leach field go fallow for a few months to revitalize soil, prevent overloading, and reduce the growth of bio-mat. Three director valves will allow splitting flow between four separate leach field lines. And seven director valves will allow splitting flow between eight separate leach field lines. You can stagger installations with an even number of diverter valves, splitting flow into unique percentages to dial-in percolation area saturation. Director valves make for a very professional and longer lasting leach field versus using often wildly inaccurate distribution boxes or tee manifolds.

Geotextile Fabric - professional duty for use with Infiltrator chambers

While not 'required', it is best practice to place a layer of gravel atop the chambers and cover with geotextile fabric before backfilling atop in sandy and silty soils. This additional step is recommended when soils are loose or sandy and would otherwise tend to wash down into the chambers. The primary place for geotextile fabric is above the gravel layer of your leach field lines, French drain, or drywell leach pit. Additionally, one can line the outside walls/sides of the excavated leach pit or drain lines to keep soil from migrating into the gravel from sides. This sidewall protection is always recommended when soils are loose or sandy and would otherwise tend to wash soil into the gravel. Geotextile fabric is also used for wrapping perforated pipe-in-gravel French drains, as pictured at right, with fabric on the bottom of trench too. French drains are wrapped like a burrito, unlike septic leach field chambers where the fabric is on the top and sides only. Protecting your leach chambers and perforated pipe gravel from soil and root infiltration is crucial to long-term soil percolation and preventing leach field failure.

Never install plastic 'visquene' sheeting or cheap non-woven 'weed barrier' landscaping fabric in place of professional grade heavy-duty woven geotextile fabric for septic system leach fields, drywell pits, French drains, or soil stabilization in foundation drainage projects. Besides longevity, the problem with using visquene plastic sheeting or cheap weed barrier non-woven materials, is they suffocate the soil, ultimately causing anaerobic soil conditions, biomat formation, root rot, and molding issues. Plastic sheeting becomes brittle and tears within a few years and the adhesive bond holding non-woven weed-barrier fabric together eventually decomposes, slipping, ripping and tearing, and allowing sand and soil to migrate into the gravel drainage layer of leach field or French drain. Invest in our professional grade woven geotextile fabric with a full 35 mil thickness and extra heavy-duty five ounce per square yard weight. Built for a lifetime of service, this is one of the only 'hydrophilic treated' materials on the market, with needle punched, multi-layer woven polypropylene design technology that lets air, water, and nutrients through, but keeps the soil out. Hydrophilic fabrics are critical in septic and greywater leach fields where oxygen penetrating into the soil is vital for long-term performance and protection against soil percolation failure. Unlike most fabrics, it features a very functional 'fuzzy' side that lays down against the soil to prevent slippage, making it very easy to install on sloped ground. The shiny smooth side has printed stripes every foot on center, full-length, for gauging trench elevations, rock fill levels, or lining up plants. Click here for our geotextile soil fabric engineering specifications and material MSDS sheet. This professional grade geotextile polypropylene fabric has proven itself over time to be a superior performer, as compared to other '20+ year landscaping fabrics'.

Professional strength, heavy-duty woven 35 mil thick geotextile fabric is hydrophilic treated to
allow air, water, and nutrients through its needle punched, multi-layer technology construction.
French drain trenches install fabric on all sides to prevent dirt from entering the gravel layer around perforated pipe.
Septic wastewater disposal lateral lines and leach pits do NOT install fabric on the bottom side, underneath gravel.

Free 48 State Delivery

All shopping cart items are advertised as Free Shipping with no extra charge for delivery. Shipping and handling fees are factored into advertised total delivered price. Note shipping is only available to the 48 contiguous United States of America. We do not ship into Canada or Mexico, Puerto Rico, Alaska, Hawaii, Virgin Isles, APO/FPO mailboxes, or any off-shore or international destination. Inventory 'stock' items will ship within 2-3 business days from one of Our warehouses. Scheduled deliveries are not possible to arrange, but We automatically email tracking information after shipment, so you can anticipate delivery date. Motor freight deliveries do not include lift gate service to lower boxes onto the roadway, unless quoted with additional services. If need be, lift gate service to lower boxes onto roadway is available for an additional $65 to $100 fee. Street-side motor freight deliveries are not brought to your front door by the driver, like UPS and Fed-Ex package services. Client must meet motor freight truck deliveries on the street to unload and inspect shipments by hand before signing for Merchandise. Shipments must be accepted promptly within three days of arrival at local freight terminal or storage fees of +/- $50 per day, per pallet may apply. Any and all storage fees billed by trucking company are the sole responsibility of Client and must be reimbursed to Our company.

Fed-Ex and UPS Ground

Most shopping cart items ship via Fed-Ex or UPS Ground package delivery service. Package delivery services, unlike a motor freight carrier (see next paragraph), will allow us to file a hidden damage in transit claim for insurance reimbursement, but We are given less than a week to report it. Regardless of how well the exterior of container box appears, you must ALWAYS have the driver note ANY damage to shipping boxes in writing before signing. Then immediately, always take Merchandise completely out of its packaging and inspect ALL of the Merchandise, notifying us immediately should there be ANY hidden damage to Merchandise. Mechanical problems are covered under the manufacturer warranty, but hidden aesthetic damages (cosmetic dings, dents, broken Welds, significant scratches, or popped rivets) you discover than a week after delivery are not reimbursed or replaced by Fed-EX, manufacturer, Kobe, or Not saying that you or your Merchant caused the damage to the unit before or during installation, but that possibility exists when Merchandise is not properly inspected upon arrival. Additionally, any appearance (non-mechanical) flaws found after installation will not be reimbursed or replaced by freight carrier, Fed-EX, manufacturer, Kobe, or Merchandise that has been installed is not eligible for return or replacement by

Motor Freight Shipping

Servel refrigerators, Sun-Mar composters, larger custom shade panels and larger Kobe range hoods ship via motor freight 'common carrier', as noted on the website and receipt. Scheduled deliveries are not possible to arrange, but We automatically email tracking information after shipment, so you can anticipate delivery date.Common carrier motor freight is shipped on a pallet with boxes covered in clear plastic stretch-wrap and is defined as street-side motor freight drop, which differs from small package services like UPS and Fed-Ex, in that the truck driver does not bring Merchandise into your building or onto the porch. Street-side motor freight drop is a basic delivery service, often in a full-size tractor trailer, where driver parks in street while you unload and inspect the Merchandise. Kobe range hoods, shade panels, and Sun-Mar composters are not shipped with lift-gate service. You must unload boxes from the tractor trailer by hand. If you require lift gate service to lower the Kobe range hood down onto the roadway, with what they call a mechanical 'Tommy lift', it is available for an additional $65 to $100 fee. Please arrange and pay for this optional service at time of order. Always check the number of pieces (boxes) present against the stated waybill shipping receipt tally. As with any motor freight shipment from any distributor, be certain to carefully examine ALL of the Merchandise, not just the outside of shipping box(es), before signing and accepting delivery. It is imperative with motor freight shipments that ALL products be unboxed and fully inspected PRIOR to accepting delivery. Regardless of what the delivery driver may say, you MUST inspect fully before signing and accepting the delivery. It is the freight truck driver's job to wait while you open and inspect shipment for damages. Simply looking at the outside of the box(es) is NOT adequate. Damaged Merchandise (that particular box, not all the boxes) must be refused delivery. Once someone signs for shipment, it confirms Merchandise was received free of ANY damage and removes liability from the transportation carrier. We can only assume that damage reported later and not refused delivery, was caused by the Client, and not the freight carrier. Any subsequent attempt to file a claim for loss or damage will NOT be accepted by the transportation carrier, distributor, or Our company,

Returns and Cancellation

All returns, cancellations and/or exchanges must first be authorized in writing by at Client may not ship any Merchandise back until We supply return Merchandise authorization RMA number and address for the shipment. Orders often do not ship back to the same warehouse they shipped from originally. Contact us with invoice number and reason for return or exchange to obtain an RMA number and instructions. No returns, refunds or exchanges will be authorized more than 30 days after original purchase payment date. Design consultation services, DVDs, knit shade material, water tubes, greywater and septic system parts are not returnable for refund or exchange for any reason. Once payment has been made, custom panel orders are cut and enter the production system and cannot be cancelled after payment is made. No return on any remnants or discontinued items. Any authorized returns of Merchandise must be in the original carton, in new unused condition, and returned freight prepaid to Our designated warehouse. Merchandise originally shipped via motor freight carrier on a pallet, may not be returned via package delivery service such as UPS or Fed-Ex. Original actual shipping cost will be deducted from any refund due along with up to 15% restocking fee on the Merchandise. This restocking fee includes the 3% credit card processing on original purchase, which is not refunded by MasterCard or VISA. Please understand that items on Our website are advertised as "Free Shipping", which is to be understood as "there is no extra charge for delivery of PURCHASED Merchandise". UPS, USPS, Fed-Ex and motor freight carriers charge us a fee for delivery of Merchandise, which We must recoup on returns. Kobe, for instance, bills a flat-fee of $40 and $45 for business and residential Fed-Ex shipments and $162 and $186 for motor freight carrier drops. Sun-Mar and Servel units ship via motor freight carrier for anywhere from $120 to $300+ per unit, depending upon zip code and drop site designation. Kobe, Sun-Mar, Clivus Multrum, Quanics, Dometic and Servel returns are manufacturer-direct, drop ship items and may be subject to an additional manufacturer's restocking fee. Discontinued, clearance items are not eligible for return or exchange. If an item is returned without original packaging intact, or is damaged, found to be used, or otherwise not ready for resale, it may be refused and returned to sender at their expense, so always insure shipment.

Lost and Stolen Shipments

Tracking information is emailed following shipment on all orders so client can anticipate delivery date. Custom size shade panels are made-to-order and can take up to ten business days to produce and ship. All other 'stock items' normally ship within three business days. Should you not receive email shipping information, please send a request for tracking number in writing to: Note it can take up to 48 hours for a given tracking number to appear on transportation company website. During this time, shipment status may be listed as "order processed and ready for pickup". Traditionally, this just means the shipment has not yet reached transportation company terminal and scanned after being unloaded from truck that picked those package(s) up. Overdue shipments must be reported to merchant in writing within one week after anticipated delivery date. Cardholder hereby agrees that only two possibilities exist for a shipment that did not arrive as anticipated. Possibility #1) Transportation company shows shipment as still being in-transit. In this case, merchant will file a 'tracer' request on behalf of cardholder with transportation company and they will search for box(es) at all company freight terminals. Cardholder is required to fully cooperate by filling out any forms requested, returning any voice messages left, and replying to any email messages sent by transportation company or merchant. Your patience and consideration is required and greatly appreciated while transportation company attempts to find the shipment. Replacement or refund is authorized solely at merchant discretion. Cardholder is not permitted to cancel order. Cardholder is not permitted to dictate choice of replacement or refund. And cardholder is not permitted to dictate time frame for settlement and ultimate delivery date for merchandise. Possibility #2) Transportation company shows shipment as being delivered. In this case, merchant will file a 'lost shipment' claim on behalf of cardholder with transportation company. A lost shipment claim can take up to two weeks to resolve and unfortunately, the transportation company rarely, if ever, pays the insurance claim. Ideally, we only ship to cardholder, personally, at their residence or business 'home' credit card billing address, but regardless of designated drop site and receiving person and whether or not a signature was required at time of delivery, cardholder is solely responsible for merchandise security after drop is confirmed by transportation company. After transportation company confirms delivery to shipping address, no signature required, there will be no refund or replacement for lost or stolen merchandise for any reason. Cardholder must immediately file a theft report with their local police department for item stolen from property or designated drop site. Cardholder hereby agrees to relinquish any and all right to file a credit card chargeback sales reversal for merchandise lost in transit by transportation company or merchandise reported lost or stolen after delivery is confirmed by transportation company. Should cardholder file a chargeback in violation of this terms of service agreement, cardholder will be held responsible for reimbursement of any and all merchant services processing fees incurred as a result of the frivolous chargeback, which can be anywhere from $35 up to several hundred dollars.

Shade Panel Production

Our commercial grade knitted shadecloth carries a one year manufacturer's replacement warranty against defects in material and workmanship. You can expect at least 5 years of service when installed properly and well over ten years when used seasonally in a temperate climate. Client must inspect shade panels within one week of delivery in order to be able to report any damages. Rips, tears, and aesthetic damage you find more than one week after delivery are not reimbursed or replaced by the freight carrier or Additionally, merchandise that has been installed is not eligible for return or replacement for damage claims. Fabric is knitted polyolefin, primarily high density polyethylene HDPE, specially treated for durability and UV resistance. Wind damage from loose panel whipping, snagging, and abrading against the structure or cable framework is much more harmful in the long run than simple exposure to sunlight. Knit shade material should be installed hung underneath, not pulled across the top of cable or framework, to avoid abrasion and snagging damage. Chemical, fire, heat, abrasion, and snagging damage are not covered under manufacturer warranty. Shade panel warranty inspection returns must be authorized in advance and returned freight prepaid to designated location for visual inspection. will only pay the cost to ship warranty repaired or replaced merchandise back to client after inspection confirms damage was a material or workmanship defect. The following are trade-standard, non-valid reasons for requesting warranty inspection: First, there is no up-down, right-left, top-bottom or front-back reference point for any panel. Panel 'Width and Length' are measured from outside-edge to outside-edge of the sewn perimeter hem at the four corners only. Knit material has inherent tension and flex in the looming process that will resolve aesthetic issues when installed taut with rope lacing. Grommets on one side of panel are unlikely to line up with grommets on the opposite side or from one grommeted pinch pleat to the next. Exact one foot on-center grommet spacing, specific grommeted pinch pleat centering, and special placement on a particular side for grommets is not warranted. Any panel over 12 foot wide may have a noticeable factory knitted loom splice seam without notice in advance since the 20, 26, and 32 foot wide stock roll width fabrics are manufactured on side-by-side looms. We traditionally cover this seam with a grommeted pinch pleat, but it is possible to order plain cloth without a center GPP, per automated quoting form. Aesthetic issues are not warranted. For instance, the White 50% color knitted shade material can sometimes arrive with patches of orange discoloration and spotting as a result of the manufacturing process. This discoloration will dissipate after installation in the sunlight. Shade material may always be slightly wrinkled from rolling onto storage tube or shipping and knit appearance can vary from sample swatches presented and may also vary between various stock widths. Minor aesthetic flaws in knit appearance, stitching, and snags are not a structural panel failure problem and not warranted. Shade material is lockstitch knitted to prevent structural unraveling. Longevity is the same regardless of aesthetic appearance flaws in the fabric knit or perimeter webbing. If need be, one can use needle and thread to pull small flaws together and super-glue sealed. It is not considered a warranty-related defect unless it affects panel performance. Special fire resistant certified shade materials are not available. The finish 'Length' ordered is what we produce by cutting enough fabric to fold hem and GPP. The only time to anticipate deviation in finish dimension purchased is when 'Width' is a stock material width of 6, 8, 10, 12, 20, 26 and 32 foot. Then, finish 'Width' is likely going to be two to three inches less after folding and sewing perimeter hem and any length-wise grommeted pinch pleats. ALL other times, the size panel you request is the finish size we do our very best to produce. Knitted shade netting is inherently difficult to work with due to tension releasing when cut to custom sizes, so trade-standard warranty for free replacement is a four inch tolerance. As measured at four corners, any error of five inches, or more, is warranted for free remake, replacement, or refund at our sole discretion. This accuracy guarantee does not apply to shapes other than rectangles or any panel dimension over 32 foot. Errors of less than five inches are considered for remedy on a case-by-case basis only when the panel has not been installed and can be resold as a new-unused remnant. Special grommet placement requests are not warranted and grommet spacing at exactly one foot on center is not warranted.
