This Presentation’s Focus
– Solid Waste Management
– Wastewater Treatment Plant
Waste, where does it go?
Backyard Burning
(affects the air)
Landfilling
(Affects the
land, air, water,
eco systems)
Recycling
(Diverts wastes)
Tribal Containers
• Large Roll-off bins accept
– Metal, yard waste, trash, cardboard
• Save costs for picking up and dumping
Community Recycling Bin
• Modified bin by Lewis and Clark Recyclers in
Lewiston, at no cost to the Tribe
• Proceeds go to the Tribe

Tribal Solid Waste Management Code:
Revenues (conservative)
Potential Annual Earnings Total = $29,730
- Pays for 1 full-time technician, fuel,
and tools
Potential Development
- Increase more recycling drop centers
- Coordinate composting
Wastewater Treatment Plant
•Start up August 27, 2011
•Approximately
$7.7 million dollar project
•Partners and funding:
USDA, IHS, Nez Perce
Tribe, City of Lapwai, and
the EPA
Wastewater Treatment Plant
• Tribally owned, City of Lapwai bought capacity
into the plant
• The City pays annual operation and
maintenance costs based on sewage flows
• Approximately $300,000 in revenue collection
from billing 363 Equivalent Dwelling Units
including shared O & M costs from the City of
Lapwai
Wastewater Treatment Plant
Plant uses cutting edge
technology with a
membrane bioreactor
(MBR) filter system
Produces Class ‘A’
water and bio-solids
Filtration/Separation
o The membranes sit in the
wastewater (mixed liquor)
o Clean water is pulled
through the membranes
by pumps
o Most bacteria, viruses,
pathogens, solids, etc.
are too large to pass
through the membrane
pores

ranges
from $50
- $70,000
annually
Part of
O&M
Costs
MBR Cartridges
14 pumps
and biosolids
pasteurized
at high
temperatures
The MBR
Permeate is then transferred to a holding tank
for Ultra Violet treatment to kill bacteria
Potential developments Greenhouse @
Wastewater Treatment Plant
Green house from the
effluent, about 100,000 gpd
Bio Solids used in
composting, producing a
ton per week
