Treatment MeasuresLitter Traps : Costs Checklist

Use the checklist form below as a guide to assessing the life cycle costs of litter traps.

INSTALLATION
Does the trap satisfy:		YES	NO
	- the design flow rate
	- the available space constraints
	- hydraulic and flooding issues
	- other concerns (safety, aesthetics, etc.)

if any of the above questions were NO then go no further with that trap.

Trap cost		$ _____________
Installation costs (if not include in supply)		$ _____________
Other costs (rock excavation, lid loading, access road for maintenance etc.)		$ _____________
	TOTAL INSTALLATION COSTS	$ _____________

MAINTENANCE
		YES	NO
Is a maintenance contract included in the proposal?

If YES…	What is the annual maintenance cost?	$ _____________
	What are the expected costs of disposal?	$ _____________

	TOTAL MAINTENANCE COSTS	$ _____________

IF NO…	Cost of special maintenance equipment (cranes, trucks, pumps etc.)	$ _____________
	Cost of maintenance (including frequency, time, crew etc.)	$ _____________
	Estimated disposal costs (regard to expected loads and material type)	$ _____________
	Safety requirements (safety equipment hire, additional site equipment)	$ _____________

	TOTAL MAINTENANCE COSTS	$ _____________

EQUIVALENT ANNUAL COST
Life cycle costs = Installation costs + (n x Maintenance costs) n (Where n = project duration (years)
