Excavation, Septic & Sewer Services in Star, ID

A Contractor Built for the Way Star Is Growing

Star sits along the Boise River and Highway 44, straddling the Ada and Canyon county line, and it has gone from a quiet farm town to one of the fastest-growing communities in Idaho. That growth shows up in the dirt. On one side of a road you will find flood-irrigated pasture, mature acreage lots and homes on septic and wells; on the other, brand-new subdivisions cut into former farm ground with municipal sewer and water stubbed to the curb. Shamrock Construction & Excavation works comfortably on both sides of that line.

We bring more than 30 years of Treasure Valley excavation experience to every Star project, from a single trench on a rural parcel to full site development for new construction. Because we handle the digging, the utilities and the drainage under one roof, you get one crew that understands how each part of the job affects the next.

Septic on the Acreage, Sewer in the Subdivisions

Star is a community in transition underground. Many established properties still rely on septic systems and private wells, while newer neighborhoods tie into public sewer and water. We work on both. For rural and acreage properties, we install, repair and replace complete septic systems, and our dedicated Star septic services page covers what that looks like locally. For homes and businesses on city services, we trench and install sewer lines and water lines, and we handle the conversions when a property near a new main is ready to leave its septic tank behind.

• Sewer line installation, repair and hookups
• Water line trenching and installation
• Septic-to-sewer conversions
• 24 hour emergency response for failed lines

Site Prep on Former Farm Ground

A lot of new construction in Star happens on land that spent decades as irrigated farmland. That history matters when it is time to build. Old field grades, ditch lines and soft, worked soils all have to be dealt with before a foundation goes in. Our excavation crew handles clearing, rough and finish grading, building pad prep and foundation digs, and we compact backfill properly so your flatwork and footings are not fighting settling ground a few years down the road.

Managing Water Near the River

Between the Boise River lowlands, seasonal high groundwater and the legacy of flood irrigation, water management is a real issue on many Star properties. Soggy pastures, standing water after irrigation season and damp crawl spaces are common complaints, especially on lots close to the river. We design and install drainage systems that move water away from structures and put low, wet ground back to work. Read more about how we approach it locally on our drainage solutions in Star page.

• Yard and pasture drainage correction
• Downspout and surface water routing
• Regrading for positive drainage
