New Septic System Installs & Replacements

Septic Systems Built For Reliable Long-Term Performance

Solano County sets minimum tank capacity by bedroom count, starting at 1,200 gallons for a three-bedroom home and climbing to 1,800 for five, and it requires a full 100% replacement area held in reserve on every parcel. Those numbers shape the design long before a shovel moves. River Rats Septic Services installs and replaces septic systems throughout Rio Vista, CA, and across Solano, Sacramento, Yolo, Napa, Contra Costa, and Northern San Joaquin counties, on standard and engineered designs alike.

Every install starts with a site visit and a hard look at soil and groundwater, because a design that ignores either will not survive its first wet winter. After 20+ years of installs here, we bring in engineers when the parcel demands a designed system, carry permits and inspections through the county, set the tanks and dispersal lines, and finish with a walk-through that covers exactly how to care for it. Our contact page opens the conversation.

Permits, Soil, And Sequence Handled In Order

Bobby has designed and installed hundreds of systems, and the pattern that separates a good install from a callback is almost always sequence. Testing before design, design before permit, permit before excavation. Skipping a step to save a week usually costs a month somewhere further along in the same job.

Replacements carry their own wrinkle. Sacramento County waives the test drill only when the original design can be verified and the system ran 8 to 12 years without repair, and current code requires replacing 100% of the original leaching system. We check that history first so the budget is real. Start on our contact page.

Septic Systems We Install And Replace

Site Evaluation and Soil Review

Nothing gets designed until the ground has been read. Soil texture, percolation behavior, seasonal groundwater depth, slope, setbacks to wells and watercourses, and available reserve area all get established first, because each one narrows what can legally be built.

Standard Gravity System Installation

Where soil and separation allow it, gravity remains the simplest and most durable arrangement. Tank, distribution box, and trenches go in with proper bedding, fall, and cover, giving you a system with no pumps or electricity to fail.

Engineered and Alternative System Installation

Poor percolation, shallow groundwater, or an awkward parcel calls for a stamped design. Pump chambers, timed dosing, pressure laterals, sand filters, or mounds get built precisely to the engineer's drawings and then commissioned before anyone signs off on them.

Full System Replacement

Aging systems reach a point where repairs stop returning value. Replacement covers decommissioning the old tank safely, removing or abandoning spent dispersal lines, and building the code-compliant system that the county now requires on that particular parcel today.

Permit and Inspection Coordination

Applications, test drill appointments, engineer submittals, and inspection scheduling all move through us rather than landing on your desk. Every jurisdiction here runs its process slightly differently, and knowing those differences prevents weeks of avoidable waiting between stages.

Tank Replacement and Decommissioning

Cracked, collapsed, or undersized tanks get swapped out without disturbing a functioning dispersal field. Abandoned tanks are pumped, crushed or filled in, and documented properly, which closes an open liability that otherwise surfaces later during a property transaction.

Why Choose Us for New Septic System Installs & Replacements

Designs Matched To Real Groundwater

A drawing that works in August can drown in February on this ground. Reading seasonal high groundwater rather than the day's conditions is what keeps a new dispersal field functioning through the wet months of its first year.

Permits Filed Correctly The First Time

Rejected applications cost weeks, and weeks matter enormously when a household is living around a failed system. Applications go in complete, with the testing and design attachments each county expects, so review time stays as short as possible.

One Contractor Start To Finish

Evaluation, engineering coordination, excavation, tank setting, dispersal construction, and final inspection all stay under one roof. Nobody hands you off between trades, and nobody blames the previous crew when some small detail turns out to have been missed.

Reserve Area Protected

Counties require a replacement area for a reason, and losing it to a shed or a driveway creates a genuine problem decades later. We mark and explain that reserve so future projects on the property avoid building over it.

A System You Know How To Run

The walk-through at completion is not a formality. You learn where the lids are, what the filter needs, how the controls behave if a system has them, and what a normal year of use should look like on a system like yours.

Repairs Covered By The Same Crew

The people who buried it are the people who come back if anything needs attention. That continuity means a service call starts with somebody who already knows the layout, instead of somebody standing there probing your lawn from scratch.

Build It Once, Build It for the Water Table You Have

A septic system installed against the real conditions of a parcel disappears into the background for decades. One installed against optimistic assumptions announces itself the first winter the groundwater comes up, and by then the concrete is already in the ground. River Rats Septic Services has put systems into some of the wettest, softest, most permit-sensitive ground around Rio Vista, CA, and the approach has never changed: test honestly, design for the worst season, and build exactly what the drawings call for. If you are planning a new build or staring at a system that has finished its run, our contact page is where the site visit gets scheduled.
