Maintenance for Stormwater Treatment Practices

Without maintenance, the performance of any stormwater treatment practice will decline over time until it reaches an unacceptable level. Thus, every stormwater management plan should include an estimated schedule for maintenance activities, and funds should be budgeted to support this schedule. This chapter provides recommendations for maintenance activities based on the treatment practice and assessment results and also presents typical suggested corresponding frequencies of such activities. In addition, this chapter provides the results of a maintenance activity survey, again grouped by the type of practice, that offers insights on typical issues that trigger the need for maintenance, maintenance complexity, and maintenance frequency.
