As your partner in water resources management, we provide guidance and technical assistance to ensure you’re in compliance with federal regulations – including temporary discharges.
Whether you’re line-flushing water, dewatering or have process water as part of a short-term project, our Source Control team is here to support you. Our process helps you navigate regulations and dispose of wastewater responsibly.
To get started, select your type of temporary discharge below, follow the instructions and submit the appropriate application. Once received, your Source Control Investigator will route your request through different departments for comment and final approval.
Cities, recreation centers, water districts, fire departments and contractors often need to dispose of chlorinated water. Different options are available, based on a variety of factors.
Follow these guidelines whether the discharge is from water line flushing or disinfection, swimming pool cleaning, hydrant testing and other activities:
Chlorinated water discharges to the sanitary sewer system must be restricted to reduce the risk of an overflow event. Discharges involving uncontaminated potable water can be approved by a two-day expedited process with this application (PDF, 2.2MB).
Wastewater discharge from remediation sites is rare, but can pose huge environmental risks. Prior to discharging this or discovered contamination during construction, fill out an application (PDF, 24KB). It will need to be submitted it at least two weeks in advance to allow for proper review and approval.
Other temporary discharge requests are evaluated on a case-by-case basis. Whether from construction dewatering, waterline purification, batch water disposal or another temporary event, submit an application (PDF, 24KB) at least two weeks before discharge.
