Chuck,there is a lot of half correct information following your post. First drip is not cheaper than sprinklers. A 1000 ft roll of tubing is $300+ versus $60 for three sprinklers and there is a huge labor difference in the installation of the two. Drip being the labor intensive one. Secondly, pooling could be caused by several different things and is usually case specific. Like sprinklers there is an application rate that controls the sqft of area needed to disperse the effluent on your drip or spray system. So, depending on other information you may be willing to provide on your specific situation I may be able to help you. Otherwise, some of the causes may be design related (wrong application rate), effluent quality related, site related (drainage issues), and/or age of product issues.
There are other causes but the above listed ones are the main ones.
SCHEMELLBA99 Properly maintained and operating aerobic systems should never have a strong odor associated with them. A musty to earthy smell is normal without the presence of chlorine. Chlorine is used for the disinfection process not the treatment process. However, a poorly operating aerobic system may have some odors and through the disinfection process the requirement of the chlorine to first oxidize solids before a break-point is achieved may offer some additional treatment to effluent whereby a reduction in the odors may be noticed. This being said if there is not an increase in the chlorine to meet demand, to reach the break-point and to achieve a long term chlorine residual there will be limited disinfection of the effluent. Typically, chlorine should be added on a very regular base to the septic system. Most tablet chlorinators work better with one to two tablets every two weeks. Regular Chlorine in = regular disinfection.
Wear and tear on a pump should not be a concern if the drip system is properly designed and the pump is:1.) used in the correct application, 2.) sized/matched with the pump curve to the flow/pressure requirement of the drip system, 3.) properly maintained and serviced
AGGIE95 Aerobic systems are not required by counties/local jurisdictions unless stated in their local order with TCEQ. Most aerobic system requirements are wrote into the deed restrictions of subdivisions and are not a requirement of the county in most cases.
