The SFPUC said the algae presents a seasonal problem, although the factors responsible for the current bloom have yet to be determined.
"Recently, we have received some sporadic reports of clogged aerators, filters, and screens with algae from various customers in the regional system," said Tyrone Ju, director of communications. "We are currently investigating and will report back on our action when we have determined the cause. In the meantime, people experiencing a decrease in pressure or flow are advised to simply remove the aerators, filters, and other screens to clean them."
In an online post to its customers, CalWater said the algae presents no health hazards. Both water utility companies are cleaning their screens and filters more often, and they suggest customers do the same.
