2. Riser on pump tank(sealed and watertight) with firmly secured lid, i.e.,hex bolts or
locking devise(a 1000gal.11quid*capacity pump tank is required for surges of Uh).
3. Screw caps at ends of laterals.
4. Clean outs brought up to finished grade or enclosed within riser. Maximum
angle permitted is 90 degrees (should be 2-45degree fittings).
5. Orifice holes must be faced at 12 o'clock position(may have end hole facing down for
drainage). '
6. Orifice shields required or cover with length of larger diameter pipe cut lengthwise.
7. Ball or gate valves on laterals near manifold if installed on a slope.
8. When a pressure drainfield is installed on a slope downslope from the septic tank:
A. Install dosing tank(pump tank)below•drainfteld and have the-pump line enter the
manifold from the bottom. if this pump location would not allow for inspection and/or service of
the tank, the pump tank will be placed upslope of the drainfield next to the septic tank.
B. Construct/install anti-siphon devise in pump tank to avoid siphoning downslope to
drainfield area, and install ;
C. Pressure/valved manifold (located at top of drainfield) used with a separate line to each lateral r;
D. Hydroteck valve(mechanical ratchet)or;
E. Some other device that assures equal distribution of all laterals and keeps the bottom
lateral from being overloaded.
9. Check valves on manifold between laterals if installed on a slope, to prevent effluent
from running to bottom lateral and overloading the bottom lateral.
10. Valves must be Schedule 40 or greater..
11. Valves acccessible within riser.
12. All piping must be a minimum of Class 200( laterals,manifold and transport
pipe).
13. Septic tank filter required, unless followed by a dosing(pump)tank where a screened vault filter
surrounding the pump will be required(note: maximum pump capacity when using a sceened vault is
30 gaidmin.). It will be recommended to have both filters.

_ encroachments,if any.
2. Check the moisture content of the soil at 7-8"deep.If it is too wet,smearing and compacting will
result,thus reducing the infiltration capacity of the soil.Soil moisture can be determined by rolling a
soil sample between the hands.If it crumbles,site preparation can proceed.If the site is too wet to
prepare,do not proceed until it dries out.
3. Use extreme care in site prep.Remove"NO"top soils.Use care in tree and stump removal.Leave
root systems intact.Cut off larger trees at the surface when possible.Stump grinding is always an
option if removing the stump will disturb too much soil or lose soil depths in the process.
4. Trench bottoms must be level.Follow contours of the slopes.
5. The location of this drain field system is based upon the owner,or owner's agent,locating the
property lines and comers.If those locations are not accurate,the designer is not liable for mistakes
that may occur in the location of the drain fields,home,or any component relating to this septic
design. --
6. Brush piles and debris are not to be burned on top of the proposed drain field sites.
7. Do not use the drain field sites for storage of excavated dirt,parking areas,lumber packages,or
anything else that will disturb or destroy the areas.
. 8. For protection of the drain field sites,they are to be roped off and protected,prior to and during any _
construction.No traffic of any type is allowed on top of the proposed drain field areas.
9. Removable effluent screens are to be used.Installation and use of this septic system without effluent
screens may cancel any warranty,expressed or implied.
10.Topography,benchmark,stub out and invert elevations are based upon assumed data and may not be
absolutely correct in all cases.Elevations shown are only approximate.
11.Encroachment of the house and/or driveway into drain field areas may render this design and site
unusable.
12.All roof drains and downspouts shall be directed into a gutter infiltration system,or away from the
drain field sites.
13.Do not install this drain field system in depressed areas where surface water can collect The final
grading over the drain field sites must provide for proper surface water run off.
14.This system is not designed for the use of a garbage disposal and may cause a premature failure.
15.This system requires a proper degree of maintenance.Certification of the design and installation
does not insure trouble free service.An Operation and Maintenance Specialist should be contacted
fos.these type of services.
16.Waste strengths are not to exceed normal strengths for residential applications.Normal residential
sewage waste strengths are as follows:CBOD5-125 mg/L;TSS-80 mg/L;and oil&grease-20
mg/L,OR MEET THE EFFLUENT QUALITY CRITERIA OF THEIR RESPECTIVE
TREATMENT LEVEL FOR THEIR SITE.
17.If a D-box is used in this application,speed levelers must be used.
18.If soil depths are lost during site prep,or during any step of installation,this design and site may be
rendered useless.
19.If the drain field consists of shallow trenches,once installed and inspected for cover up,place a
minimum of 12-18"of a good,clean,off site sandy cover over the entire drain field site.The system '..
owner is then to plant grass over the drain field and maintain its growth. '..
20.If the stub out of the septic tank is lower then the invert of the laterals,a pump system becomes
required.On a designed gravity flow system,watch the final elevations of the home,septic,tank,and '..
drain field to assure a gravity flow.A designed pump system will most likely always require a pump.
21.If a curtain drain system is not designed for this site,the option must remain open if unforeseen
problems occur in the future.
22.The installer must adhere to all the health department regulations.
23.All tanks with in this system must have risers to the surface of the ground.
24.If unforeseen surface water shows up for any unexpected reason,and is with in the required set back
distance to the drain field sites,the designer is not to be held liable for this occurrence.
25.THE OWNER OF THIS SITE IS RESPONSIBLE FOR FILLING THE SOIL LOG HOLES AS
SOON AS THE COUNTY INSPECTIQN IS COMPLETE UNLESS OTHERWISE
CONTRACTED WITH BPS SEPTIC DESIGNS AND O&M.
26.Do not use soil logs o a benchmark-soil logs simply define soil profiles.
27.Prepare site and install drain field system during dry conditions.
28.Operation and Maintenance is requirEd.This system is to be set up for Operation and Maintenance
accessibility following all the minimum requirements as set forth by the health department.The
system owner must contact an O&M Specialist for these type of services.
29..If infiltrators are used in this application,they are to be installed per the manufacturers specs.
30.Observation ports are required and must be installed in such a way as to meet all the county codes.
31.Any pressurized water lines with in 10'of any septic component are to be sleeved,or rerouted.
3;.All sewage lines that are driven over must be sleeved to protect from crushing.
33.All known wells that impact the subject property are shown to the best of our knowledge and the
knowledge of the subject property owner.
34.Maintain a minimum of 100'from all wells unless approval has been granted from the health
department. _
35.A clean out is required between the foundation and the septic/pretreatment tank.
36.If a pump to a gravity fed drain field is being installed,it is highly recommended that a timer and
counter be used to help regulate the daily water usage.
37.An impervious surface runoff infiltration pit(bed)may be required.If so,this will need to be
designed separately.
