Under direct supervision, learns and performs semi-skilled work in support of all District collection system installation, inspection, preventive and corrective maintenance and repair activities; assists in performing underground televised wastewater line inspection and hydrocleaning of lines; assists in inspecting and performing preventive maintenance, servicing and mechanical repair of stationary pumping station and mobile equipment; and performs related work as required.


Receives direct supervision and training from the Wastewater Maintenance Superintendent and functional and technical direction from the Wastewater Maintenance Worker II or III. Exercises no direct supervision of staff.


The Wastewater Maintenance Worker I is the entry-level class in the maintenance worker series. Initially under close supervision, incumbents with basic maintenance experience learn District infrastructure, systems, and facilities, use of tools and equipment, and assist and participate in all District activities required to install, inspect, maintain and repair collections system facilities and equipment, including main sewer lines, laterals, pumping stations and mobile equipment. As experience is gained, assignments become more varied and are performed with greater independence. Positions at this level usually perform most of the duties required of the positions at the II level, but are not expected to function at the same skill level and usually exercise less independent discretion and judgment in matters related to work procedures and methods. Work is usually supervised while in progress and fits an established structure or pattern. Exceptions or changes in procedures are explained in detail as they arise. Since this class is often used as a training class, employees may have only limited or no directly related work experience. Assignments may vary with the skill and training of the incumbent; however, all employees are cross-trained in all assignments and the use of all equipment. This class is distinguished from Wastewater Maintenance Worker II in that the latter independently performs the full range of skilled work in all areas of collection system maintenance and repair. Positions at the II level are normally filled by advancement from the I level requiring one (1) additional year of experience and after gaining the knowledge, skill, experience, licenses, and certifications which meet the qualifications for, and after demonstrating the ability to perform the work of the higher-level class. When filled from the outside, two (2) years of prior related experience are required that allows the person to meet the qualification standards for the II level.
