( l UNDISTURBED SOIL 1_ All septic systems, regardless of type, have finite life spans and as such O will not operate indefinitely. In accepting this plan, the owner understands and accepts that repair and/or replacement of all or portions of this a 4"0 PERF. 24" system will likely be required at some time in the future. PIPE. EXTEND 2, Proper and diligent monitoring and maintenance will maximize the life of O TO BOTTOM ON this system and is required. Monitoring & maintenance guidelines were PIT prepared for this system and were submitted with these plans to the 1` original owner; these guidelines must be understood and implemented for J '6 the system to function reliably. All subsequent owners must secure a o�5Po5�i! T��Nc� S�cT�oNS copy of, understand, and implement the monitoring and maintenance guidelines or this design will be considered invalid. _...... 3. This system is designed to accommodate a finite quantity of domestic 481------- NO7 TO SCALE wastewater generated by a single--family dwelling. Non—residential wastewater will not be treated properly by this system and will damage its components. Wastewater generation exceeding the daily design flow rate listed elsewhere on these plans is likely to damage the system or cause o failure and is strictly prohibited. 4. All toilets and shower heads connected to this system must meet the i following specifications: toilets shall have a maximum flush rate of 1.6 gallons per flush; shower heads shall have a maximum flow rate of 2.5 gallons per minute. 5. Garbage disposal units will increase the need for septic tank pumping, will increase the treatment load on the system, and will likely reduce the system's functional life. These units, therefore, are strongly discouraged. 6_ Recreational vehicle holding tank chemicals can damage this systems microbiology and must not be discharged into the system. 7. The creation of cut banks below the disposal or replacement areas increases the possibility of interception and surfacing of migrating effluent and should always be avoided. Cut banks below the disposal or replacement areas are created solely at the risk of the owner. j 8. The disturbance of native soils within or below the disposal or I replacement areas increases the possibility of soil structure damage and R may lead to disposal field failure. Disturbance of native soils within or tC} below the disposal or replacement areas by any means including �_ 0 vehicular traffic, grading, livestock, etc. is prohibited and will invalidate O m m this design. 03 C� ti cr7 a O E INSTALLER'S RESPONSIBILITIES �°, m � Q � 1. Construction of this septic may be undertaken only after obtaining a Q 0 O q permit from the regulatory outhority(ies). Do not begin construction prior to approval of this design and issuance of a permit by the regulatory outhority(ies). The owner and/or installer of this system is/are solely responsible for identifying and obtaining any other permits which may be required for construction of this system_ 2. Inspections during construction by the designer and, in some cases, the regulatory authority, ore required. The installer and/or owner are solely responsible for contacting the designer and/or regulatory authority at least 24 hours in advance of each required inspection. Every effort will be made to respond within 24 hours, however O additional notice may sometimes be required. 3. The permit and an approved set of design documents must be on c N the job site at all times. U 4. The installer and/or owner are solely responsible for ensuring that _J V 0) all property boundaries are accurately marked, that alt appropriate setbacks are observed, and that underground and/or overhead O ot = U utilities and/or utility easements are identified prior to construction. W U) These design documents may not show all present utilities. Z 5. Under no circumstances shall the disposal or replacement areas, or LJ J O O the relative positions of the other system components, be modified Q � without the prior consent of the designer and the regulatory cl� W cQ (J authority(ies). Q O 6, If the soil in the disposal area can be formed into a ribbon it is too W wet to excavate. Do not remove vegetation, operate equipment, or otherwise manipulate soils in the disposal area until receiving approval from the designer. 7. Disturbance of native soils in the disposal and/or replacement areas �P�ct 1sr and for a distance of 50 feet below the disposal or replacement areas may damage the permeability of the soil column and cause premature system failure. Do not allow vehicular traffic, construction r`"PJC) do equipment, or livestock in the area within or below the disposal or CD replacement areas. Q7 � s 8, Do not direct concentrated surface water runoff onto adjacent Z properties. 9. The OSI Simplex control panel utilizes magnetic motor contactors that �-A w can cause noise and/or vibration in the dwelling if mounted on the Oj yd� dwelling's exterior wail. Coordinate panel location with the owner prior to mounting to avoid conflicts. 10, All disturbed areas shall be seeded at a rate of 5 ibs./1000 s.f. with FIBERGLASS LID WITH STAINLESS STEEL BOLTS 24" DIA.
