Weather & Seasonal Operating Adjustments

Planned operational changes made proactively for winter, summer, and wet-weather seasons rather than reactively.

Cold weather often requires extending SRT to compensate for slower nitrification, a planned adjustment rather than a reaction to an ammonia exceedance.

Summer low-flow periods can concentrate loading and reduce dilution, requiring closer monitoring even without a flow-related capacity concern.

A written seasonal operating plan, reviewed and updated annually, helps ensure these adjustments happen proactively rather than being rediscovered each year after a problem appears.
