Underground Utilities for New Construction
Complete underground utility installation — water, sewer, electrical, telephone, and cable TV — for residential and commercial new construction projects.
Your Underground Utility Partner
GLPS Sewer Services provides complete underground utility installation for new residential and commercial construction projects throughout South Bay and greater Los Angeles. We work directly with general contractors, developers, and property owners to get every underground system installed on schedule and to code.
With 20+ years of experience and a fully OSHA-compliant crew, we handle everything below grade — from the first trench to the final inspection — so your project can move forward without delays.
Utilities We Install
Water Lines
Domestic water service, fire suppression mains, and irrigation supply lines — sized and installed to code for residential and commercial projects.
Electrical Conduit
Underground electrical conduit for power distribution, service connections, site lighting, and EV charging infrastructure.
Telephone & Cable TV
Conduit and direct-bury cable for telephone, internet, fiber optic, and cable TV — coordinated with your telecom provider.
Sewer & Drainage
Sanitary sewer laterals, storm drain connections, and site drainage systems designed and installed per project specifications.
Our Process
Pre-Construction Planning
We coordinate with engineers, architects, and general contractors to plan utility routes, depths, and connection points before breaking ground.
Utility Locating
All existing underground utilities are located and marked to prevent conflicts and ensure safe excavation throughout the project.
Trenching & Installation
We trench and install all underground utilities — water, sewer, electrical conduit, telephone, and cable TV — to code and per project specifications.
Inspection & Backfill
All work is inspected and tested before backfilling. We coordinate with inspectors to ensure every system passes before the next construction phase begins.
