ASTM C – Home, Health and Environment: Why Septic Tanks Matter

Your email address will not be published. First rule of septic tanks: Excess flows are discharged into the tank, often from nondomestic sources.

Limit garbage disposal use. The drain field is poorly designed or installed and does not allow equal distribution of the applied flow across the field. Have your septic tank routinely pumped. Here is the inside track to help you understand the current dilemma: The septic tank is not designed or constructed according to standard to be watertight and structurally sound. The tank should be made of high-strength concrete minimum of 5, psi [35 MPa] and contain sufficient steel reinforcement to ensure the structural integrity of the tank at full design operating conditions.

Concrete strength, reinforcing steel placement, and openings shall also be considered in the design. Historically, EPA and other professional organizations have determined that asmt additives have not been shown to serve any useful purpose. Absolutely no down spouts, AC condenser drains or other clear water discharges are to be connected to your tank.

These products are, at best, a waste of money and can ast, harmful to the biological processes in the tank or drain field.


ASTM C1227 – Home, Health and Environment: Why Septic Tanks Matter

Well-built and well-maintained septic tanks systems are remarkable engineering designs. On the other hand, a quality precast concrete septic tank built to standard is structurally sound before and after installation. In fact, many regulatory jurisdictions pay lip service to standards that clearly describe how septic tanks are to be c11227 and constructed to be structurally sound. This specification covers monolithicor sectional precast concrete septic tanks.

All residential septic tanks should be a minimum of 1,gal. The engineer who designs the tank construction must be competent in concrete and structural x1227. The physical design requirements include: Quality septic tanks are structurally sound and absolutely watertight and comply with the industry standard for design requirements, manufacturing practices and performance requirements: Seven typical causes of septic system failure: The homeowner must provide attentive not passive care and maintenance of the septic tank system for as long as he or she uses the residence.

Unfortunately, every locality uses different design rates. This abstract is a brief summary of the referenced standard.

This means that septic tanks are critical issues — they can be buried but should never be forgotten. Conclusion and responsibilities Many players are involved in providing you with a quality septic tank system:.

For too long, septic tanks have been treated as a commodity rather than as an engineered product that requires skill and care in manufacturing. The regulatory inspector must enforce diligently to ensure that all tanks within his or her jurisdiction are constructed, installed and maintained in accordance with competent regulatory requirements.

The septic v1227 is not properly maintained; tank solids have built up and discharged to the drain field causing clogging failure of the field. C127 could this have possibly happened?

The following materials shall be used for manufacturing concrete septic tank: In some states and localities, this standard may be adopted by reference into the state and local codes. Many regulators are poorly trained in the science of wastewater treatment, septic tank design or tank maintenance requirements. With all the regulatory programs around, why are there so many septic tank problems? In North Carolina, for example, a three-bedroom design means the dispersal field is sized for gal.


This is gal. The following tests shall also be done: Killing the bacteria means removing the ability of your septic system to function — never a pretty sight.

A septic system relies on viable bacteria to breakdown human waste. 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.

Without the soils that surround it and hold it together, a poor-quality tank will collapse when filled with water. Do NOT use commercial additives in your septic tank. Nothing goes into the septic system that has not first gone through your digestive system or was intended to. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.

Business development seminars held for the septic tank installers and pumpers encourage the sale of such additives to homeowners as a high-profit revenue asgm for the industry. Link axtm Active This link will always route to the current Active version of the standard. Most homeowners will have a garbage disposal whether it comes with the house or is added later. The usually recommended clean-out schedule is every three to five years or longer if you have a bigger tank.
