Orange Water and Sewer Authority 152 400 Jones Ferry Road I OWASA P.O. Box 366 ,r,--377V1=4,7.7) Carrboro, NC 27510 ' (919) 968 421 December 7, 1987 Ms. Emily Crudup Planning Department Orange County 306F Revere Road Hillsborough, NC 27278 Dear Ms. Crudup: SUBJECT: PRELIMINARY PLANS FOR DAL-RAE FOREST AND LOTS 2 AND 3 IN LYNWOOD Thank you very much for providing Orange Water and Sewer Authority (OWASA) staff the opportunity to review the preliminary plans for Phase I of Dal-Rae Forest, and Lynwood Lots 2 and 3. The following comments are offered for consideration by Orange County during the subdivision review and approval process for these projects. The O,ASA Board of Directors has not reviewed and considered the proposed projects or. the GWASA staff comments. However, the Board of Directors has previously expressed concern about: (1) the increased dependence upon on-site and cluster wastewater disposal systems without a comprehensive program in place to provide for the effective, long-term operation, maintenance and inspection of these systems; and (2) the need for effective sedimentation, erosion and stormwater control measures for all land disturbing activities in local water supply watersheds. General Comment: Based on available information, the proposed development density of one dwelling unit per 2 acres is generally acceptable from a water quality protection standpoint; provided, however, that sedimentation, erosion and stormwater control measures, and wastewater disposal systems are properly designed, installed, operated, and maintained in perpetuity. Septic Tank System Concerns: It is assumed that individual septic tanks and soil absorption fields will be utilized for wastewater disposal for these projects. Because of the nature of their design, septic tanks and subsurface absorption systems should not-be expected to give trouble-free service over the life of a house. 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. OJASA staff requests that careful consideration of the following recommendations be given by the party requesting the minor subdivision, Orange County, and Orange County Health Department: An Equal Opportunity Employer
