Sci-Tek has been providing services for the water and wastewater conveyance and treatment industry for over 20 years for municipal authorities in the Pittsburgh, Philadelphia, and Harrisburg areas. We contribute to resolving regional wet weather challenges through integrated planning programs and site-specific design projects. Our team consists of engineers and scientists that provide water management solutions to our local clients and communities. Annually, more than 60% of Sci-Tek’s revenue is generated from water and wastewater conveyance and treatment plant engineering and planning projects. The services we can provide include:

  • Engineering Services: site civil design, storm & sanitary sewer and water main design and rehabilitation, permitting, environmental site assessment and remediation
  • Project Planning: project and program management, performance study, site priority and planning, flood mitigation and control planning, and geospatial data analysis and visualization.
  • Stormwater Management Design: site civil design development, public and private stormwater retrofits, and design of Green Stormwater Infrastructure (GSI) facilities.
  • Geotechnical Services: subsurface explorations for water supply, stormwater and wastewater conveyance, and GSI facilities inclusive of logging test borings and test pits, infiltration testing, evaluation of soil and rock properties using site specific data, and geotechnical reporting.
  • Water and Wastewater Analysis: hydraulic and hydrologic modeling and design of dams, canals, drainage facilities, and other small structures.
  • Surveying and Mapping: topographic and boundary surveys; right of way, easement and ALTA land title surveys; aerial control, wetland, and as-built surveys; deed research and legal descriptions; and construction stakeout
  • Flow and Water Quality Monitoring
  • Construction and Compliance Inspections


Four Mile Run GSI

Pittsburgh Water and Sewer Authority

Four Mile Run encompasses Schenley Park and several Pittsburgh neighborhoods including Greenfield, Hazelwood, Oakland, and Squirrel Hill. The Four Mile Run stormwater improvement project will capture and route the flow of stormwater through a naturalized surface channel that will generally follow the path of the historic streams that formed Four Mile Run from Panther Hollow Lake to the Monongahela River. For this project, Sci-Tek is providing flow monitoring coordination, site explorations, and permitting services.

Sci-Tek is providing water resources engineering and analysis services in support of hydrologic and hydraulic (H&H) modeling, sewer flow and precipitation data analyses, and tracking systems support.  H&H models are used to estimate runoff and infiltration and inflow from the areas of the City of Philadelphia served by combined and separate sanitary sewer systems and to simulate the conveyance system carrying the flow. The models also help with studying the combined sewage quality and quantity reaching the Water Pollution Control Plants and overflowing to the receiving water bodies.

ALCOSAN is undertaking the transfer of various pump station and equalization facilities under its Regionalization effort. These pump stations and equalization tanks have undergone a facility assessment to identify operational status, condition, safety concerns and capital improvement needs.  Three pumping facilities have been identified for rehabilitation and include Brush Run Pump Station in Upper Saint Clair, Herbst Hollow Pump Station, in Kennedy Township, and Oakdale Pump Station in Oakdale. As a subconsultant to Gannett Fleming, Sci-Tek is providing the surveying, geotechnical engineering, and environmental consulting services.
