Health Services APPROVED Initials � ' Date d CONSTRUCTION NOTES! ! 1 . Check the moisture content of the soil at 7"-8" deep. If it is too wet, smearing and compacting will result, thus reduc- ing the infiltration capacity of the soil . Soil moisture can be determined by rolling a soil sample between the hands. If it rolls into a ribbon, the site is too wet to prepare. If it crumbles, site preparation can proceed. If the site is too wet to prepare, do not proceed until it dries out. 2 . Use extreme care in site preparation. Remove no top soils. Use care in tree removal and stump removal. 3 . Do not deviate from this design with-out the permission of the designer. 4 . Drainfield sites are to be roped off prior to and during con- struction of home to protect the soils and/or system from any kind of traffic. soils can be damaged easily. 5. A certified professional installer is required to install this system. This person must be certified by the County Health Dept. to install septic system. All others do not qualify. 6. The curtain drain ( if required by designer) is to be install- ed a minimum of 8" into compaction and tight-lined, meeting all county codes. See attached sheet for design of a curtain drain if required. 7 . Maintain a minimum of 100 ' from any standing water unless other wise ok"ed by the designer and County Health Dept. . If you cannot maintain the 100 ' then stop work and notify the. designer at once. 8. Maintain a minimum of 10 ' from any and all water lines that are under pressure. 9 . Wheels and tracks of equipment are not to come in contact with infiltrative surfaces. 10. The bottom and sidewalls of the excavation should be left with a rough open surface. 11 . Filter screens are to be used on the outlet side of the septic tank. These screens are to be used to screen the fine solids from the effluents prior to final disposal. These screens must be made accessible for cleaning purposes. ADDITIONAL NOTES ! ! 1 . Keep pump tank (dosing tank) below elevation of top laterial in primary area! 2. Gate valves are required between the manifold and each laterial to regulate head pressure! 3 . Check valves required in the manifold between laterial runs to illiminate system bleed back! 4 . Dry wheather install ! 5 . Remove no top soils! ***** 6. Curtain drain system is required. See diagram drawing for design! SOIL LOG INFORMATION! !

This pressurized system will be used in a trench system. (SEE TRENCH DESIGN) 2. System configuration: A. 0.E,JTE✓L manifold B. Check valve installed in transport line near pump chamber. C. 8 laterials are to be used. 4- on each side of the manifold. D. Laterals and a portion of the manifold are to drain between doses to minimize freezing problems. Also, it reduces settling of solids. E. Orifices are to be at a 6 o'clock position. The final orifice at the distal end of the laterial can be placed at the 12 o'clock position for draining purposes, testing, and air venting. F. Transport line is to remain full by use of a check valve. G. Clean-outs at the end of each laterial shall be provided. Threaded end caps are to be provided. H. Laterials are to be level. 3. In order to eliminate the potential for erosion into the gravel of backfill material over lying the bed, a synthetic filter fabric (not untreated building paper, straw, or such) shall be used. (TYPAR #3201 OR EQUIVALENT) 4 . Precautions must be taken so pumping chambers do not float out of position due to hydrostatic pressures on the nearly empty tank. 5. All electrical controls shall be mounted outside the tank and meet applicable code. Also, an easily separated union shall be used. for easy pump removal when it becomes necessary. 6. Where the low water level in the dosing chamber is above the laterial inverts, pumps must have a siphon breaker. A small "weep" hole drilled in the discharge line at the highest point in the dosing chamber can act as a simple siphon breaker. 7. The Washington State committee finds evidence that effluent screens are beneficial and effective in preventing the pumping of solids into the small diameter distribution system. Screens shall meet the following minimum criteria: A. 1 /8" mesh size. B. Non corrosive materials. C. A minimum of 12 ft. (squared) of surface area. D. Cannot interfere with switches or floats. E. Shall be easily removable for thorough cleaning. 8. The mercury level control switch is required. 9. The pump chamber shall be inspected every six months to check the condition and proper performance of the switch system, pump, and alarms. NOTES N PRESSURIZED SYSTEM (cont"ed) 10. Systems installed with a pump timer or counter and a pressure gage shall be checked periodically to ensure that doses are being delivered at the design volume and frequency; the pump controls and throttling valve shall be adjusted accordingly. 11 . Observation ports shall be installed to monitor the effluent in each trench or bed. 12. Non-corrosive shut-off type valves are to be installed between the manifold and the laterials for final adjustment for equal pressure to each laterial. 13. Pressure calculations on exact elevation differences are as close as possible due to no "exact" location of the system components. Some minor re:calculations may be required once the home and septic components are in place. The gate valves installed in each laterial will help regulate the needed residual head. • CURTAIN DRAIN DETAIL Overfill — nrnnnc3 Rnifar-P • ; • • - - • . Sandy.

SMALL DIAMETER PIPE Transport, manifold, and lateral pipes must be Class 200 or better. 3. BARRIER MATERIAL Geotextile (filter fabric) is required as a barrier material for all alterna- tive systems. 4. PUMPS A. Pumps must be effluent rated and constructed with cast iron housing, stainless shaft, all stainless hardware, and oil-filled motor hous- ing. B. All electrical connections located exterior of pump chamber or in an enclosed, corrosion resistant splice box with cord grips. C. Pump connected with disconnect coupling device above maximum effluent level so that lines do not have to be cut in order to remove pump. D. Pump equipped with flow measuring device in commercial systems E. All mechanical components effluent rated. F. Discharge pipe of effluent pump minimum of 11/. inches. G. Pipe of noncorrosive nature; PVC pipe of Schedule 40. H. Pump or enclosed vault inlet 2 inches minimum above bottom of the pump chamber. 5. PUMP/SIPHON CHATS A. In areas of high seasonal water tables, concrete pump/siphon chambers must be watertight. To insure this, they may be sealed with "Thoro- seal" or its equivalent. Unsealed chambers must be filled with water and allowed to stand overnight to assure no more leakage than 0.001 x total tank capacity. B. Access cover constructed of durable material and water tight. C. Access cover at or above finished grade and adequately secured. D. Gasket used on contact surface between access cover and pump chamber to prevent escape of gases and intrusion by insects or vermin. E. Finish grade contoured to prevent surface water ponding at access cover. F. Pumps protected with screens or effluent filters. 6. CONTROLS A. Adjustable mercury float switches utilized with redundant "off." B. Alarm sensor connected above high level float switch to warn of pump failure. C. Alarm circuit separate from pump circuit. D. Alarm control box located within audible range. 7. MAINTENANCE FEATURES A. Minimum of 1 cleanout at the end of each lateral by using sweep 45°- B. Cleanout protected with section of capped 4-inch diameter PVC pipe extended 4 inches above finished grade, or marked with metal stake maximum of 6 inches below finished grade. C. Minimum of two observation ports: one to detect ponding at interface between drainrock and sand; one to detect ponding at interface be- tween sand and natural soil. D. Observation ports constructed of 4 inch diameter PVC, extended 4 in- ches above finished grade, or enclosed in durable, accessible box. E. Observation ports equipped with easily removable caps. • • • Revised 04/22/92 THURSTON-MASON~HEALTH DISTRICT .
