It has been reported that they have an average effective life of 10 to 15 years, assuming no misuse, before rehabilitation, modifications or replacement is necessary. Furthermore, leaving septic tank system maintenance solely to the discretion of the typical homeowner, with the need for septic tank pumping and maintenance to be determined as they deem necessary or as problems occur, is, in essence, very limited control over the potential adverse impact of these systems on water quality. Therefore, consideration should be given to an alternative septic tank system design and maintenance concept. OIASA staff requests that careful consideration of the following recommendations be given by the developers of each project, Orange County, and Orange County Health partment: a. A dual absorption field system should be required to be installed at the time each lot is developed (alternating use between the two fields on a regular basis) , with provision of an additional back-up field area for one of the dual drainfields. OWASA staff recognizes that this will result in increased construction cos and greater initial clearing for the system installation; however, the long-term benefits to water quality, public health and future ho should offset these costs. wners within these subdivisions b. All septic tank system replacement si es which have been identified by the Orange County Health Department should be clearly designated on the plat and deed/survey for each lot. These sites must be required to remain undisturbed and reserved by present and future owners for such use, in the event the primary site malfunctions. there have been cases where reserve sites identifieeddby th e aware Hal that Department have, in the past, been rendered unusable due to construction of improvements after the initial residence has been completed. 2.
