Underground Utilities Design

Site Water, Sewer & Fire-Line Design

Underground utility design from the building service to the public main — coordinated with the water/sewer authority and permitting.

What We Deliver

  • PE-signed underground / site-utility plans and details
  • Domestic water main and service design with sizing
  • Sanitary sewer main and lateral design
  • Fire-line and backflow / RPZ layout
  • Water meter, sewer connection, and service-tap details
  • Utility-authority coordination and permit package

Who It’s For

  • General contractors and developers on site-development projects
  • Owners extending or upsizing a building’s water and sewer service
  • Design-build teams needing civil utility design alongside the building permit

Engineering Scope

  • Water Distribution: Domestic and fire-service mains, services, sizing, and pressure analysis
  • Sanitary Sewer: Gravity mains and laterals, slope and invert design, cleanouts and manholes
  • Fire Lines: Fire-service mains, backflow / RPZ assemblies, and FDC coordination
  • Connections: Water meters, taps, sewer connections to the public main
  • Authority Coordination: Water/sewer-authority (e.g. WASD) requirements, permitting, and review responses
  • Permit Package: Signed & sealed civil utility plans with calculations

Pricing

Starting at $7,500. Final fee scales with site scale, the number of services, and the water/sewer-authority review load. Underground utilities are commonly scoped alongside Civil & Site Engineering and Grading & Drainage Plans.

Compliance Notes (Florida)

  • Local water/sewer authority (e.g. Miami-Dade WASD): Design standards, connection, and capacity requirements
  • FBC & FDEP: Site utility, separation, and environmental requirements
  • NFPA / fire marshal: Fire-line and water-supply requirements where applicable
  • FDOT / county: Right-of-way and roadway-crossing requirements for utilities in the public ROW
