Thinking about a move to Tres Pinos and wondering how wells, septic systems, and propane fit into daily life? You are not alone. Rural utilities can feel unfamiliar at first, yet a little knowledge goes a long way toward a smooth purchase or sale. In this guide, you will learn what to check, who to call, and how to plan upgrades with confidence. Let’s dive in.
Why these systems matter in Tres Pinos
Tres Pinos is an unincorporated community where many homes rely on a private well, a septic system, and propane for fuel. Local oversight is shared by the San Benito County Water District for wells and groundwater and County Environmental Health for drinking water safety and onsite wastewater. You will also work within California’s state rules that counties adopt and enforce locally. Knowing the agencies and records to request helps you avoid surprises during escrow.
- For local well information and permitting, start with the San Benito County Water District’s wells resources. Visit the district’s wells page for guidelines and contacts: San Benito County Water District wells.
- For septic and drinking water questions, San Benito County Environmental Health is your local point of contact: County Environmental Health programs.
Wells: what to verify before you buy or sell
Use Well Completion Reports
The best technical record for an existing well is the DWR Well Completion Report. It typically shows drilled depth, casing, formations, and the reported yield at the time of drilling. Request the report for the parcel through the state map and records system: California DWR Well Completion Reports.
Order water-quality testing
Plan for a lab analysis from an ELAP-certified lab. A common panel for rural California wells includes total coliform and E. coli, nitrate and nitrite, and, based on local risk, metals like arsenic and manganese, plus VOCs or pesticides. The state outlines what private well owners should test for here: California drinking water testing guidance. Annual bacteriological checks are a good habit.
Consider local conditions
Groundwater depth and well performance can vary even between neighbors. Nearby agriculture, older septic systems, or surface drains may influence your testing choices. Use the Well Completion Report and any county records to understand the well’s construction and context before you rely on neighbor anecdotes.
Who to call for wells
- Start with the Water District’s wells page for local procedure: SBCWD wells.
- Use the DWR portal for Well Completion Reports and instructions: DWR WCR map and requests.
- Contact County Environmental Health with wellhead safety or drinking water questions: San Benito County Environmental Health.
Septic systems: rules, records, and upgrades
Know the state framework
California’s Onsite Wastewater Treatment Systems Policy sets the baseline for siting, design, and maintenance of septic systems. Counties implement this policy and may have a Local Agency Management Program that adapts standards to local soil and groundwater conditions. Read the policy overview here: State Water Board OWTS Policy. The Central Coast Regional Water Board lists San Benito County’s LAMP status as in progress, so always confirm current local procedures: Central Coast RWQCB LAMP status.
Gather records for a sale
Ask for the most recent septic inspection and pump records, plus any permits and as-built plans for repairs or replacements. If you plan to add bedrooms or finish space, have a qualified professional review the current capacity and layout early. Tank sizing often ties to bedroom count, and additions may require a system evaluation.
Understand typical setbacks
Many California counties use minimum horizontal separations between wells and septic components to protect water quality. A common example is about 100 feet between a private well and a leach field, as shown in other county codes that follow state policy. You can see an example standard here: Typical county setback example. Always verify San Benito County’s current setbacks and procedures with Environmental Health before designing improvements.
Maintain the system
A well-designed and maintained septic system can operate for decades. Regular pump-outs, water-use awareness, and avoiding fats and solvents help extend the life of the tank and leach field. Keep all records in one place so you can share them during a future sale.
Propane: ownership, permits, and safety
Confirm tank ownership and size
Rural Tres Pinos homes often run on whole-house propane. Common tanks are 250 to 500 gallons and may be aboveground or buried. Confirm whether the tank is owned by the seller or leased from a supplier, and request the written agreement if leased. For a sense of local suppliers active in the area, you can review vendor listings like this example: Dassel’s Petroleum service area.
Expect permits and code checks
Tank installation and relocation typically require a permit and inspection by the local authority that enforces fire and building codes. Installations follow NFPA 58 standards for siting, piping, and safety. If you plan any changes, coordinate with the fuel supplier and the Authority Having Jurisdiction. Learn more about the standard here: NFPA 58 overview document.
Plan around the tank
If you are adding a driveway, pool, new foundation, or septic work near a propane tank, get site plans and written clearance from the supplier and local officials before digging. This protects safety and keeps your project on schedule.
A simple checklist for Tres Pinos buyers and sellers
- Request the DWR Well Completion Report and any county well permits or inspections: Find and request WCRs.
- Order a water test for bacteria and nitrate at minimum. Add arsenic, lead, manganese, and VOCs based on risk: Testing guidance.
- Gather septic records: last inspection, pump receipt, permits, and as-built plans. Confirm capacity if you plan additions.
- Verify propane tank ownership. Obtain the lease or proof of ownership, delivery invoices, and any installation permits.
- Before planning improvements, confirm current local rules and timelines with County Environmental Health: San Benito County Environmental Health.
When to bring in professionals
You get the best results when you combine clear records with qualified specialists. For wells, look to licensed well drillers and ELAP-certified labs. For septic, consult registered engineers or designers familiar with the OWTS Policy. For propane, coordinate with a licensed supplier and the local fire or building department.
