The Westend Regional Sewage Services Commission was established in 1994 by Regulation of the Government of Alberta.

The Commission was formally composed of two members each from Councils for the Towns of Black DIamond and Turner Valley.  It is now composed of members of Council from the Town of Diamond Valley and 2 members at large.

Regular meetings are held as per the schedule on the town website Events Calendar. The Commission does not regularly meet in December, July or August although meetings may be held in any of these months if conditions warrant. The meeting agenda is released on the Thursday afternoon prior to the meeting.

The Westend facilities are composed of the Turner Valley lift station, equipment in the Black Diamond lift station, the sewage lagoons, the blower building the transfer station and the approximately 180 acres of property on which they sit in Black Diamond.

The Commission is funded through requisitions to each of the Towns. The Commission's expenses include utility costs, operator costs, maintenance and repair costs, administrative costs and reserves. The amount paid by each town is based on their respective proportion of the total annual sewage flow (January 1 to December 31).

The Commission contracts operation of its facilities through the Diamond Valley Public Works department. It contracts administrative services through an independent contractor.
