Plum Creek Wastewater Masterplan & Treatment Plant #1 Expansion

Tetra Tech RTW prepared a wastewater masterplan for Plum Creek Wastewater Authority (PCWA) that encompassed system capacity needs and growth projections, effluent reuse program, wastewater treatment plant site improvements, biosolids management, and a CPE of PCWA's two wastewater treatment plants.

As a result, PCWA's Plant #1 was expanded from 1.45 mgd to 3.55 mgd and included the following improvements:

Activated sludge system converted to a nitrifying activated sludge system using four treatment basins,

Gravity belt thickener installed for biosolids thickening to 5%,

Aerobic digester capacity increased through conversions of existing treatment basins,

Two sludge storage lagoons added for aerated biosolids storage for at least 96 days,

Sodium hypochlorite disinfection added,

RAS pumping system modified and added new pumps and blower capacity,

Influent pumping capacity, automated screenings conveyor system, and barscreen bypass channel added to plant headworks,

Implemented a plant SCADA system using Intellution FIX DMACS software.

Tetra Tech RTW developed a multi-media O&M manual using Microsoft Access and FIX DMACS software. Involved integrating graphical images and O&M information in Access with accessibility from the FIX operating system.
