Your annual inspection should check: Septic tank failures can result in dangerous situations, from a cave-in to contact with untreated human waste. Exceeding the designed limits reduces the ability of the septic tank and drain field v1227 function. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

Homeowners often choose the lowest-cost system available.

ASTM C – National Precast Concrete Association

Depth of sludge and scum Condition of scum layer That the inlet tee is clear Proper operation of any installed pump Cleanliness of any effluent filter present In addition, your drain field or drip area should be walked to check for any wet or soggy spots that would indicate pending or actual system failure.

In the real world, many poor-quality septic tanks are installed every day and yes, these are the tanks that are likely to fail structurally and create health and environmental risks.

If the tank is not equipped with an effluent pump, an effluent filter should be installed on the outlet.

On the other hand, a quality precast concrete septic tank built to standard is structurally sound before and after installation. As a result, thin-walled tanks with little or no steel reinforcing are installed every day; there might even be one in your own backyard.

Not all septic tanks are made of steel-reinforced precast concrete or fiberglass-reinforced plastic and therefore are not structurally sound and watertight. With all the regulatory programs around, why are there so many septic tank problems?


Have the clean-out done by a professional septage firm, making sure it services and reinstalls the effluent filter if installed and make sure all access devices are secured back into place.

The precast concrete sections shall be cured. The drain field is too small for the intended use, or drain field soils are inadequate to treat and move flows away from the site.

Ignore such sales pitches. Business development seminars held for the septic tank installers and pumpers encourage the sale of such additives to homeowners as a high-profit revenue source for the industry.

The solution is to size the septic system to handle the extra solids produced by these devices. Work Item s – proposed revisions of this standard.

These products are, at best, a waste of money and can be harmful to the biological processes in the tank or drain field. To ensure watertightness, the inlets and outlets must be equipped with aatm boots integrated into the tank wall inlet and outlet pipes pass through these boots and the boots sealed against the pipes with stainless steel clamps.

Historically, EPA and other professional organizations have determined that such additives have not been shown to serve any useful purpose. Concrete strength, reinforcing steel placement, and openings shall also be considered in the design. Installers of poor-quality tanks know that they are relying on the subsoil for structural support.

So what incentive drives some producers to market tanks that are not watertight or structurally sound?

The regulatory inspector must enforce diligently to ensure that all tanks within his or her jurisdiction c12227 constructed, installed and maintained in accordance with competent regulatory requirements. Without the soils that surround it and hold it together, a poor-quality tank will collapse when filled with water.


ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date. In addition, your drain field or drip area should be walked to check for any wet or soggy spots that would indicate pending or actual system failure.

Structural design of the septic tanks shall be by calculation or by performance. A watertight riser must be permanently sealed to the riser ring, extended to grade and be equipped with a locked or bolted watertight lid.

Excess flows are discharged into the tank, often from nondomestic sources. Checklist for Quality Your quality septic tank atm meet this 8-point checklist: Regardless of the validity of locally established design rates, they must be followed. Here is the inside track to help you understand the current dilemma: The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. If you simply forget the tank and pay no attention to it, one of these days you will be standing in your mucky, stinky yard while some burly guy with a backhoe digs holes in your lawn as dollar signs flash in front of your eyes.

Quality septic tanks are structurally sound and absolutely watertight asgm comply with the industry standard for design requirements, manufacturing practices and performance requirements: The following materials shall be used for manufacturing concrete septic tank: Wstm and well-maintained septic tanks systems are remarkable engineering designs.
