ROB'S EXCAVATING 1871 E.IOHN.S PRAIRIE RD SHF.LTON, WA 98584 (3(6 426-6697) INSTALLATION / MAINTENANCE PRESSURE DISTRIBUTION SYSTEMS t. Install laterals with contour of the ground. '2. Install trench bottoms level and at all times a minimum of six inches into the native soil. 3. Install locator tape on top of all drainfield laterals. 4ti 4. Install observation ports as indicated on the plot plan (minimum two per drainfeld NFq� with bottom extending to the drain rock/native soil interface). UN 2 9 ZQ FPS 0� 5. Install drainfield during dry weather and soil conditions, and soil smearing must be AS+D eliminated by hand raking. 6. Install threaded clean-outs at the ends of all laterals(cap must extend to within 6 inches of finished grade and be marked with locator tape). 7. Install audio/visual high water alarm. 8. Install 1/8 inch mesh non-corrosive pump screen (min. 12-sq. ft. surface area, not to interfere with controls or floats). 9. Install check valve in pump outlet line to prevent system from draining back into the pump chamber. 10. Filter fabric required over drain rock prior to backfilling. If the drain rock extends above natural grade, run the filter fabric at least 2 inches down the trench wall. 11. Divert all storm water run-off away on-site sewage system. 12. No curtain drains allowed within 10 ft. or the up-slope edge of the drainfiMd and reserve area. 13. No curtain drains allowed within 30 ft. of the down-slooc edge or,-,., drainfield a"d reserve area. ,14. Have the septic tank and pump chamber pumped or inspected every three to five years. 15. Inspect floats, clean pump screen and test water alarm every 6 — '2 months as needed. 16. All materials and workmanship must meet County and State regulations. 17. Septic tank risers to be at or above finish grade. 18. Deviation from this design without prior approval from the Designer and Mason County Health Department will make this design null and void. 19. Pump chamber lid to be above finish grade. 20. The on-site septic system owner is responsible for properly operating and maintaining the OSS and shall: a) Determine the level of solids and scum in the septic tank once eJllQAPR0 cD three years. ®c b) Employ an approved pumper to remove the septage from the tank SUN 2 9 2000 EPT when the level of solids and scrum indicates that removal is necessaryp c) Protect the OSS area and the reserve area from: an 1. Cover by structures or impervious material 2. Surface drainage 3. Soil compaction by vehicular traffic or livestock 4. Damage by soil removal and grade alteration d) Keep the flow of sewage to the OSS at or below the approved design both in quantity and waste strength. 21. High strength waste will increase the depth of the biomat in a drainfield, causing a decreased flow through the biomat and possible ponding or flooding of the drainfield. High strength waste in a residence is usually related to the"lifestyle or habits of the home, generally resulting from one or more of the following: a) Excessive use of a garbage disposal b) Consecutive loads of laundry done all on one day c) Excessive bleach or detergents with added whiteners d) Dishwashing, showering, and laundering all at the same time e) Medications—antibiotics can kill or impair the biological process in the septic tank. f) Leaky plumbing(hydraulic overloading) SKHD150 SP40 SP50 MAX.SOLIDS 3/4"S PHER E MAX.SOLIDS1-1/4"SPHERE MAX.SOLIDSI-1/2"SPHi 1-1 /2 HP 4/10 HP AP 1/2 HP 3450 RPM 1750 RPM Mc HPop P JUN ALTH DEpT 2 .9 2000 PSD A 1 I • Dual shaft seals standard.Seal • Available in automatic and manual • Available in automatic and me failure sensor capability available • Oil-filled ball bearing motor • Oil-filled, heavy-duty ball beari (to be wired to an alarm device) incorporates automatic reset motor • 1-1/2 HP,oil-filled motor thermal overload • Enclosed,two-vane cast iron • Rugged cast iron construction • Non-clog,two-vane thermoplastic sewage-type impeller • 1.1/2-NPT discharge sewage-type impeller • Automatics feature oil-isolatee • Spring loaded mechanical seal • Automatics feature reliable level control diaphragm switch with.carbon and ceramic faces diaphragm switch with piggyback cast iron housing •-Non-clogging semi-open plug-in • Rugged cast iron construction thermoplastic impeller • 2"NPT discharge • Mechanical shaft seal with car • Pump-out vanes on rear shroud of • Rugged cast iron construction and ceramic faces _-- impeller • Stainless steel shaft • 2" NPT discharge(3"flange • For high head septic tank effluent • Completely field serviceable optional) applications • Residential sewage ejector or high • Completely field serviceable • 1.1/2 HP, 10 230V and 3e 200V, capacity sump pump • All bronze model(SP50AB1)in 230V,460V or 575V • 4/10 HP, 1 a 115V or 230V automatic, 1. 115V • 1/2 HP, to 115V, 200V,230V 3e 200V, 230V.460V or 575V tsP yF n 2 W W us d 24 Mte ztb a - :::I -ZL - 0 0 °EE• a 2e oo a so eo °o ze 40 eo eo toe 120 °o az 64 ee 12e 1e0 CAPACITY-U.S.O.P.M.
