Systems Design Engineering

What Systems Design Engineering does

Systems Design Engineering (SDE) is a multi-discipline professional engineering and consulting firm founded in 1988 and headquartered in Leesport, Pennsylvania, with a second office in Pottsville, PA. The firm provides civil, mechanical, electrical, plumbing, structural, environmental, and municipal engineering services to clients across eastern Pennsylvania and, via Professional Engineering licensure, across more than 15 states spanning the Mid-Atlantic, Northeast, Southeast, and Midwest. SDE serves five primary customer segments: municipalities and authorities (water/wastewater infrastructure, code enforcement, subdivision review), food and beverage facilities (with a notable specialization in craft brewery design and turnkey delivery), healthcare and medical facilities, educational institutions, and commercial/industrial/residential developers. The firm's portfolio includes notable projects such as the $21M Deer Lake WWTP regionalization for Schuylkill County Municipal Authority (which consolidated five treatment plants serving four municipalities and received the 2015 PA Governor's Award of Environmental Excellence) and multi-decade engagements with D.G. Yuengling and Sons, MillerCoors 10th Street Brewery, Big Storm Brewery, and Quattro Citrus Products.

The firm's service portfolio spans the full project lifecycle from feasibility studies and land use planning through permitting, design, construction administration, and inspection. Core technical capabilities include water/wastewater treatment design with GIS and hydraulic modeling integration, medium-voltage electrical power systems with fault and arc flash studies, mechanical HVAC and process piping for food and beverage facilities, structural engineering across multiple materials, and municipal code enforcement with UCC-certified staff. SDE holds Professional Engineering licenses in 16 states and operates a wholly-owned construction subsidiary, SDE Construction Inc, enabling turnkey design-build delivery.

SDE generates revenue through professional fee-based engineering and consulting services billed on a project basis, supplemented by construction services revenue through its subsidiary. The go-to-market is sales-led and relationship-driven, with projects acquired through municipal RFPs, direct enterprise engagement, and long-term client referrals. Primary customers are enterprise and government clients with multi-year engagement horizons. Marketing relies on the company website, project portfolio case studies, industry reputation, and referral networks rather than paid advertising. Ownership is private and founder/management-held, with no external private equity or venture capital investors identified in available materials.
