“We exposed the existing gravity sewer from the house to tie in a new sewer force main, then completed one bore under the driveway and a second bore to the backyard. After installing and connecting the grinder pump system, the project was completed smoothly and without delays.”
Compact Utility Installation for Backyards, ADUs & Cottages
Get all your backyard utilities in without tearing up your landscaping. We specialize in tight-access, trenchless horizontal directional drilling (HDD) to place conduits and pipes under lawns, trees, retaining walls, pavers, and concrete walkways—quickly, cleanly, and with minimal disruption.
What We Install
Power: PG&E OQ qualified for electric service runs to ADUs, cottages, garages, and shops
Gas: Service lines for appliances, outdoor kitchens, fire pits, and pool heaters
Sewer—Grinder Pump + Force Main: Full grinder pump connections with pressure sewer laterals
Water: Domestic water lines and irrigation feeds
Telco & Fiber: Conduits for internet, phone, and smart-home systems
Security & Site Systems: Conduits for cameras, gates, lighting, and intercoms
Outdoor Amenities: Gas and power to fire pits, landscape lighting, sheds, and studios
If you can dream it, we can likely bore it—without damaging your mature landscaping or hardscape.
Remote PG&E Meter Option
A remote PG&E meter is a cost-effective solution that simplifies utility installations by shifting the meter location to the edge of PG&E’s ownership. From the remote meter to the house or ADU, the conduit and sub-panel installation become part of the private system, giving you more flexibility in placement without being restricted by PG&E’s Greenbook requirements (such as setbacks from windows and other constraints).
When starting your PG&E design process, request a remote meter—it can save time, reduce headaches, and provide more options for your project layout. Our team can guide you through this process from the start to ensure a smooth and compliant installation.
This option is available for both gas and electric services.

“After the client’s concrete patio was completed, they decided to add a fire pit. We installed a new gas line beneath the existing concrete to accommodate the fire pit without disturbing the finished surface.”

“Using our specialized tools in combination with excavators, we installed an E/One grinder pump and a force main sewer line. This system was designed to allow a future conversion from the existing septic system to a street sewer main connection, which we can complete when the client is ready.”
“On this flag lot, we installed a 3” PG&E electric service line, boring 240 feet from an existing #2 box in the sidewalk to a new #2 box we placed in the landscape at the end of the driveway. From there, we ran another 3” conduit to the new PG&E 320-amp service panel—all completed without requiring closure of the shared driveway used daily by four homes.”
“For this ADU project, we installed a force main sewer line, boring around a curve to the front yard. Using a two-step pull, we created a 90-degree bore to connect with the gravity sewer in the front. We also installed a new water main to the existing meter by boring under the sidewalk—avoiding costly concrete removal and replacement of both the driveway and sidewalk. This approach saved the client significant costs while keeping the project on schedule.”
