Services
Water System Modeling
Our engineers create detailed hydraulic models using Innovyze InfoWater software to evaluate municipal water distribution systems. We analyze pipe age, material, water quality, flow rates, and pressure parameters to identify infrastructure needs. Our models incorporate population projections and commercial demands to guide capital improvement planning for sustainable water supply systems.
Wastewater Planning
We develop comprehensive wastewater management plans including Act 537 compliance studies and capacity evaluations. Our team designs interceptor sewers, pump stations, and treatment facilities while implementing optimization methods like bio-towers and membrane filtration. We address combined sewer overflow issues through advanced primary treatment solutions tailored to municipal requirements.
Municipal Engineering
Our services cover storm sewer engineering, roadway paving, and retaining wall construction for townships and boroughs. We develop subdivision ordinances aligned with zoning regulations and provide construction phase monitoring. Our engineers ensure compliance with PennDOT and AASHTO standards for municipal infrastructure projects of all scales.
SCADA Services
We offer complete SCADA system implementation from design to installation, including PLC programming and HMI development. Our Rockwell Automation-certified team integrates packaged systems and provides cellular remote monitoring solutions. We maintain third-party relationships for equipment support and offer emergency troubleshooting for wastewater and water treatment control systems.
Land Surveying
Our full-time survey crews utilize GPS technology and conventional equipment for precise data collection. We support aerial mapping, facility documentation, and system mapping projects. Our surveying services provide critical baseline data for infrastructure planning and construction projects across municipal jurisdictions.
