Heartline Staffing, in partnership with Purple Cow Recruiting, is seeking an experienced Wastewater Level B Operator for a full-time, on-site opportunity in Millsboro, Delaware. This position is designed for a licensed wastewater professional with at least three years of operating experience who can independently operate a wastewater treatment shift and perform hands-on equipment maintenance.
POSITION OVERVIEW
The Wastewater Level B Operator is responsible for the operation and maintenance of wastewater treatment facilities and systems. Unlike an entry-level operator working primarily under supervision, this position requires the ability to independently operate a shift while maintaining treatment processes, equipment, laboratory controls, compliance documentation, and facility safety standards.
A critical technical component of this role is hands-on mechanical maintenance, including the ability to rebuild progressing cavity (PC) pumps. The operator will also perform process-control laboratory work, maintain compliance records, and follow established Lockout/Tagout, PPE, and Process Safety Management procedures.
KEY RESPONSIBILITIES
• Independently operate a wastewater treatment shift
• Operate and maintain wastewater treatment facilities and treatment systems
• Monitor treatment processes and system performance
• Maintain process and permit requirements throughout assigned shifts
• Perform process-control laboratory work and routine testing
• Record laboratory results and operational data accurately
• Maintain required compliance records and documentation
• Perform preventive and corrective maintenance on wastewater equipment
• Rebuild and maintain progressing cavity (PC) pumps
• Inspect and troubleshoot wastewater treatment equipment
• Assist with repairs necessary to restore equipment capacity and minimize downtime
• Maintain pumps, valves, chemical-feed systems, and related treatment equipment
• Follow Lockout/Tagout (LOTO) procedures
• Follow Process Safety Management (PSM) requirements
• Follow all required PPE and workplace safety procedures
• Identify, prevent, and report unsafe acts and conditions
• Maintain accurate operational, laboratory, maintenance, and compliance records
• Work independently while coordinating appropriately with facility operations and maintenance personnel
RELEVANT WASTEWATER BACKGROUNDS
Qualified experience may come from:
• Industrial Wastewater Treatment Facilities
• Municipal Wastewater Treatment Plants
• Food-Processing Wastewater Operations
• Large Publicly Owned Treatment Works (POTWs)
• Manufacturing Facilities with On-Site Wastewater Treatment
• Environmental Services Wastewater Operations
POSITION LEVEL
This is an experienced operator position requiring substantially more independence than an entry-level wastewater role. The successful candidate must be capable of operating a wastewater treatment shift without direct supervision and handling both operational and mechanical responsibilities.

• High School Diploma or Equivalent REQUIRED
• Minimum 3 Years of Acceptable Wastewater Operating Experience REQUIRED
• Active Level II Wastewater Operator License REQUIRED
• Ability to Independently Operate a Wastewater Treatment Shift REQUIRED
• Hands-On Wastewater Treatment Facility Operations Experience REQUIRED
• Wastewater Equipment Maintenance Experience REQUIRED
• Ability to Rebuild Progressing Cavity (PC) Pumps REQUIRED
• Preventive and Corrective Wastewater Equipment Maintenance Experience REQUIRED
• Process-Control Laboratory Experience REQUIRED
• Compliance Recordkeeping Experience REQUIRED
• Practical Lockout/Tagout (LOTO) Experience REQUIRED
• Practical PPE Safety Experience REQUIRED
• Process Safety Management (PSM) Experience REQUIRED
• Ability to Work Full-Time On-Site in Millsboro, DE REQUIRED
• Experience with Pumps, Valves, Chemical-Feed Systems, and Related Wastewater Equipment Preferred
• Industrial or Food-Processing Wastewater Experience Preferred
• Municipal Wastewater Treatment Experience Considered
LICENSE NOTE: Candidates must hold a Level II Wastewater Operator License applicable to the position. Candidates holding an equivalent out-of-state wastewater license should be able to demonstrate applicable Delaware reciprocity or transfer/endorsement eligibility.
IMPORTANT: This position requires an experienced wastewater operator who can independently operate a treatment shift. Candidates whose wastewater experience has been entirely supervised without responsibility for independently operating a shift do not meet the core operating requirement.
