23 NOTES The design flow is based upon the number of bedrooms applied for by the property owner or developer. The design flow for a bedroom is 120 gallons /day (gpd). (e.g. 600 gpd = 5 bedrooms) Proposed house locations were not provided by the property owner or developer as required by 15A NCAC 18A .1900 - .1970 (The Laws and Rules for Sewage Treatment and Disposal Systems). The design flow, type system, and pump requirement are subject to change based upon the application and site plan or plat submitted for the Wastewater Construction Authorization. The blocked areas on the accompanying plat are the limits of the provisionally suitable soils as evaluated by the Orange County Health Department. It should be noted that all lots having a conventional -type drain field with pump are reviewed at a minimum of every five years and all Pretreated Drip systems are reviewed every year by the health department as required by 15A NCAC 18A.1961 (Maintenance of Sewage Systems). Also, any Pretreated Drip system must be inspected by a Subsurface Waste Water System Operator as well. Pretreated Drip Systems are placed in areas with 18 " -23" of provisionally suitable soil /site characteristics. Ultra Shallow Trench Conventional Systems are placed in areas with 24 inches or more of provisionally suitable soil /site characteristics and a 6 -10" soil cap is placed over the trenches. Shallow Trench Conventional Systems are placed in areas with 30 inches or more of provisionally suitable soil /site characteristics. Conventional Trench Systems are placed in areas with 36" inches or more of provisionally suitable soil /site characteristics. Innovative Trench Systems can be used in areas with 24 -36 "of provisionally suitable soil /site characteristics.) The approved septic areas should be kept free of vehicular traffic, logging, grading, and compacting activities. It is the responsibility of the property owner or developer to maintain the integrity of the septic areas prior to system construction and installation. No parking, cutting or filling shall be allowed in or around the drain field areas. Drainage ways and easements should be utilized to convey storm water run -off to the storm water retention areas. These conveyances should not be located through designated septic drain field areas. This report is for planning purposes only and does not constitute any approval. Lot approval is granted by the health department only in the form of an Improvement Permit. Improvement Permits are issued once the lots are recorded and have received individual Parcel Identification Numbers.
