Population is as per FIR Schedule 90, line 0020 column 2 WWTR002 WWTR005 WWTR006 Override Population (Serviced Population) Geographic Area (Sq Kms) Override Geographic Area Where the service area population is different than the population in WWTR001 enter the service area population here. This result feeds from the Municipal data input area and is recorded in Sq Kms FIR Schedule 90, line 0040, Col 1. Hectares in the municipality divided by 100. The Override Geographic Area should be based on the portion of the Urban Service Area currently serviced by municipal sanitary sewer systems.

Density per sq kms is population (WWTR001) divided by the geographic WWTR009 Override Population Density WWTR105 Community Impact Average Age of Pipe area (WWTR005) Where the service area population (WWTR002) is different than the population in (WWTR001) enter the service area population density here. (WWTR002/WWTR008) The average age of all wastewater sewage pipes (excluding connections) within the collection system weighted by length. Length Weighted Average Age = ((length of pipe at age x) (age x) + (length of pipe at age y) (age y) +...) / total length of pipe Where age x = average age of age range x, for example for range 0-24 years, the average age is

WWTR205 Service Level KM of Pipe (excluding connections) Total kilometers of wastewater mains MPMP Schedule 91, Line 3111 Column 31 As appropriate, add to notes supplementary information on the approximate % of wastewater conveyance or collection system that has been structurally relined resulting in an increase to the Service Life. OMBI Municipalities with complete jurisdiction over the wastewater system report the total length of the system including local collection, trunk sewers and wastewater force mains.

Population as per FIR Schedule 90, line 0020 column 2 divided by 100,000 or override population if required (override population excludes rural unserviced population ) Need to use a service area population. Some OMBI Municipalities have large rural areas which are not serviced by Municipal Systems (approx. 10%-20%) of the total Municipal population. Utilizing the total population from FIR Schedule 90 (Line 0020 / Column 1) will not result in accurate reporting for this measure and will not result in proper comparisons between Municipalities (Urban versus Urban / Rural). It is suggested that the FIR (Schedule 90) be revised and that an additional column be added to Line 0020 for Population serviced by

OMBI Municipalities with partial jurisdiction over wastewater collection (Niagara, Waterloo and York) are not responsible for local wastewater collection and will report costs related to wastewater conveyance including major wastewater pumping stations, trunk sewers and forcemains. In those municipalities where the activity of water meter reading and billing results in the issuance of a bill for both water & wastewater services, then the costs of the water

Costs could be distributed based on the number of sewer or wastewater accounts relative to the total number of accounts, the number of billing transactions or other cost allocation methodologies which would fairly distribute the cost of the activity between the two service areas.
