Delivered a packaged biological treatment plant for a rural subdivision with no full-time on-site operator.
Project Background
A residential developer needed a packaged biological treatment plant for a rural subdivision, designed around a subdivision peaking factor of about 4, infiltration and inflow, low night flow and operation without a full-time on-site operator. Capacity: ~95 m³/d. Effluent limits were established from the applicable state discharge permit.
Our Solution
We delivered a packaged biological treatment plant with extended aeration and MBR considered against the permit-based limits. The design addressed peak-hour hydraulics, wet-weather infiltration and inflow, surge tolerance and remote operation. Delivery covered design, fabrication, testing, installation, commissioning, performance verification, training and handover.
