Installation Notes
Nuwater BNR500 to an Oscar Distribution
32010-50-01036 1341 E Beaver Ave
1. Installer and designer must meet on site prior to installation.
2. Oscar drainfield: ASTM C-33 sand media as per Washington Department of
Health's Recommended Standards and Guidance for Intermittent Sand Filter.
3. Order NuWater-o kit that does not come with control panel, control panel comes
with Oscar Kit to serve both the NuWater and the Oscar
4. The prepared site plan is not a survey. It's the owner's responsibility to verify property
lines, utility lines (water, sewer, power, phone and gas) prior to installation.
5. Minimum of 6" of sand throughout out the lateral area, must be level.(see page 5)
6. Septic and pump tank must be concrete and traffic rated
7. The tanks may be moved as necessary to accommodate building requirements. Septic
tank location must meet all required setbacks.
8. Keep wheeled vehicles off the drainfield area before, during and after installation.
Tracked equipment only,
9. All ground, surface water and roof drains must be diverted away from the septic tanks
and drainfield. Ensure the final grade slopes away from these areas and water doesn't
collect on or around them. Use swales, berms, catch basin and tight lines, curtain drains,
etc. to divert all waters.
10. Curtain drains can be no closer than 10' upgradient and 30' down gradient of the
drainfield
11. Exposed restrictive layers, cuts, banks, etc. can be no closer than 50' downhill from the
drainfield.
12. Install access risers on the septic tanks, valve box and ends of laterals.
13. Make sure septic tank risers are epoxied or caulked to cast in riser rings on tank.
14. Lids must form a water and gas tight seal with the access risers
15. This system must be installed by a Mason County Certified installer.
16. Deviation from this design without prior approval from the designer and Mason County
Health Department will make this design null and void.
17. This design was sized per Washington Administrative CodeWAC246-272A-0230. The
operating capacity is based on 45 gallons per day per capita with two persons per
bedroom. The minimum design flow per bedroom per day is NM, ICI
ninety gallons multiplied by 1.33. This results in a minimum 6Felibn flo , • NSe Tiun re
twenty gallons per day. This creates a surge factor of 33% but anticipated f)q,W2 ninety
gallons per bedroom per day. APR r Lu
