What's Included in an Envicon Water & Wastewater Engagement
Conveyance & Collection System Design
Gravity sewer, force main, and water main design with hydraulic modeling, condition assessment, and infiltration/inflow evaluation.
Pump Station Design & Rehabilitation
Wet-well and submersible station design, hydraulics and pump selection, controls and SCADA integration, and rehabilitation of aging stations.
Treatment & Pretreatment Systems
Process evaluation, treatment plant upgrades, and industrial pretreatment system design to meet discharge limits and local sewer-use ordinances.
Discharge Permitting & Compliance
NJPDES and SPDES permit applications and renewals, treatment works approvals, sampling programs, and discharge monitoring report support.
When Owners Engage Us
- A pump station or treatment unit is past useful life
- A discharge permit renewal brings tighter effluent limits
- Industrial process water requires pretreatment before discharge
- A development requires sanitary sewer extension and TWA approval
- Infiltration and inflow are driving treatment costs
- Capital planning requires condition assessment and cost projection
Treatment upgrade tied to a permit or grant deadline?
Tell us the flow, the permit driver, and the funding source and we'll return an engineering scope, a fee range, and a submission schedule.
