Installation Notes
Nuwater BNR500 to an Oscar Distribution
190 E Dogwood Lane 32104-52-00145
sr 1. Extreme care to be taken when clearing. Do not pull stumps in drainfield area, cut
as close to the ground as possible.
2. Installer and designer must meet on site prior to installation.
,cn '. Oscar drainfield: ASTM C-33 sand media as per Washington Department of
Health's Recommended Standards and Guidance for Intermittent Sand Filter.
*4. 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
5. 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.
Minimum of 6" of sand throughout out the lateral area, must be level.
. Septic and pump tank must be concrete
8. The tanks may be moved as necessary to accommodate building requirements. Septic
tank location must meet all required setbacks.
9. Keep wheeled vehicles off the drainfield area before, during and after installation.
Tracked equipment only.
10. 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.
11. Curtain drains can be no closer than 10' upgradient and 30' down gradient of the
drainfield
12. Exposed restrictive layers. cuts, banks, etc. can be no closer than 50' downhill from the
drainfield.
