GREATER VANCOUVER WATER DISTRICT

Water Shortage Response Plan

July 20, 1992

Water Supply System Operating Parameters:

I.

Usable volume in storage (Capilano, Seymour & Mountain Lakes):

19,785 MG

Average daily demand from sources (Capilano & Seymour) for last week:
168 MGD
Maximum allowable daily demand from sources (Capilano & Seymour) for next week
to meet 99 To supply reliability:
Demands as low as possible with reasonable conservation measures are necessary due to
depleted storag ,
Water conservation action required:
The sprinkling ban should remain in effect until storage volumes reach normal for the time

of year. As can be seen from the graph comparing present storage volume (Fig. 4) with
1987, the gap is closing, although at a reduced rate last week.

Other comments:

Recent warm weather has resulted j in increased demand. GVRD’s radio advertising

reminding of the sprinkling ban will resume later this week. Consideration is being gi given
to re-opening outlets at the mountain lakes, depending on weather conditions,
