SFPUC hears drought economic-impact study and WESIP update; staff flags conservation and regional trading as tools

The SFPUC received a briefing June 7 on drought-era economic impacts and on capital program updates, including the Water System Improvement Program (WESIP) and draft wastewater master planning.

Consultants from the Bay Area economic teams presented findings that residential consumption is the largest component of regional water demand and that the "hardening" of demand means easy conservation gains have largely been taken. In three scenarios (10%, 20%, 30% reductions) the consultants compared proportional rationing, drought-contingent pricing and a regional trading market, concluding that pricing and regional trading could substantially lower economic losses compared with uniform percentage cuts. The presentation noted drought-contingent pricing can influence demand but may require steep price increases, and that regional trading can allocate reductions to agencies best able to bear burdens and thus reduce overall economic loss.

Commissioners asked about the practical mechanics of regional trading and whether the region's agencies were prepared to trade supplies. Consultants said trading is a recognized tool in other regions, some agencies have diversified portfolios and the capacity for transfers may grow with investment. Staff also reported WESIP program updates and work on a wastewater master plan that envisions relocating digesters and improving neighborhood outcomes in the port/backlands area.

Commissioners asked staff to consider additional outreach and to return with clearer, lay-reader summaries so the public and supervisors (including Supervisor Sophie Maxwell) can understand implications for drought policy and local impacts.
