This work will supplement the work we are now doing and have already completed in planning and implementation of the Foothill Pressure Zone. To review the status of the project at this time, the tasks included in our current contract and their present status are as follows: 1. Planning and design of check valve installations to separate the Foothill and Lower Zones while allowing flow from the Lower Zone into the Foothill Zone in the event of fire or other low pressure emergency. This work is essentially complete. Preliminary plans were reviewed with City staff in November or December. We received comments from Dave van Houten early this week. The plan is now being finalized and should be ready for final review nextweek. 2. Investigation, planning and design of new and/or modified booster pumps to serve individual customers in the area to be converted to the Lower Zone. This included review of impacts on fire protection capacity. The system has been evaluated and we have made a preliminary determination of what the impacts will be. Those results have been submitted to the City for a review of our proposed service criteria. We are awaiting a decision from the City -to the minimum allowable pressure. ~c~ ' ' ' /" additional testing will need to o ments designed as necessary. JAN 2 9 1988
