Performance and Costs forPerformance and Costs for Decentralized Unit Processes

• Objective– To provide basic wastewater management p g

information to planners and decision-makers in very small communitiesM S i h– Mayor Smith

• Mission– Demonstrate the appropriateness of

decentralized wastewater collection, treatment and dispersal methodsand dispersal methods

End Products

• Factbook– Wastewater Basics for Small Communities

• Factsheets– Four collection systems factsheetsy– Eight treatment systems factsheets– Seven dispersal/disposal systems factsheetsp p y

• Spreadsheet– Economic model of wastewater optionsEconomic model of wastewater options

Cornerstone FactbookCornerstone Factbook• Wastewater Basics for

Small Community Leaders and Planners– What’s in wastewater– From wastewater to

– Commitment to O&MCommitment to O&M

Example InformationExample Information

• A quick means of determining which style is appropriate by daily wastewater volume

Second ExampleSecond Example

• Appropriateness by– Population densityp y– Soil depth– Rocky– Steep terrain– Arctic or Arid– Nutrient limits– Pathogen limits

Factsheets are more Specific

• Divided into – Collection– Treatment– Dispersal/disposal– Management

• Allows readers to focus on technologies gthat are pertinent to their community

Factsheet Content

• For each technology, these issues are discussed– What is the technology– Will it match the community’s vision– How much land is required– Issues with construction/installation– What is needed for O&M– And what will it cost

Overall Emphasis

• How will management be organized?– Existing utility or part-time dog catcher

• Where treated effluent be received?– Surface discharge, land application, etc…

• Treatment required– How clean does the water need to be

• Collection– Which collection compliments treatment and

management
