What Carter & Sloope does

Carter & Sloope is a privately held consulting engineering firm founded in 1990 by Don Carter, Tom Sloope, and Mark Gatlin, headquartered in Macon, Georgia. The firm provides civil and environmental engineering services — including water and wastewater treatment design, water distribution and collection systems, stormwater management, transportation and site development, and water resources planning — to municipalities, counties, industrial clients, and private companies throughout Georgia. Its practice is delivered through six offices across the state (Macon, Watkinsville/Athens, Canton, Moultrie, Flowery Branch, Statesboro) by a team of 85+ professional engineers, project managers, landscape architects, GIS specialists, design technicians, and grant writers.

The firm combines traditional engineering consulting with in-house grant writing and funding administration across federal programs (USDA Rural Development, EDA, EPA, Appalachian Regional Commission) and Georgia state programs (GDOT, GEFA, OPB). It leverages standard civil engineering technology — AutoCAD Civil 3D, MicroStation, ArcGIS, hydraulic and hydrology modeling tools, and drone/GPS field data collection — alongside domain specializations such as membrane water treatment plant design (notably Georgia's first-of-its-kind membrane water treatment plant) and reuse water/aerated lagoon process design. Documented project outcomes include a $20M multi-source funding package and 6 MGD treatment capacity expansion for the City of Moultrie, a doubling of the City of Thomaston's industrial reservoir capacity from 250M to 500M gallons, and the Camp Creek 4 MGD water treatment plant for the City of Cornelia.

Carter & Sloope operates as a project-based professional services firm on multi-year contracts, with quote-driven pricing tailored to project scope. There is no disclosed pricing structure, no public revenue, and no external institutional funding or investor ownership; founders retained independent control from inception. The firm has no subsidiaries, no acquisitions, and no active fundraising activity, and serves an exclusively in-person, direct-to-government regional go-to-market. Channel diversification is limited to organic social (LinkedIn, Instagram, Facebook) plus long-standing referral relationships — the business is fundamentally relationship-driven within the Georgia public-sector infrastructure market.
