A Holy City water investigation should begin at the house and work backward. Identify what supplies the taps, where wastewater goes and who owns the equipment between those points. Starting with a nearby reservoir, a water-company name or a mountain community label can produce a convincing description of the wrong system. The useful evidence is an account, agreement, permit or inspection tied to the specific residence and its parcel.
The public records reviewed here establish a local research route, not a completed assessment of a private Holy City home. No household bills, septic as-builts or permissioned inspection reports were available. The article therefore uses an original evidence packet built from actual mountain infrastructure and current County services. It complements the Holy City guide by explaining how to turn a seller’s infrastructure description into questions that the right records can answer.
A named water facility is not a household account
The CPUC-hosted 2015 Mountain System Master Plan includes a Holy City regulator and describes its role in the Montevina pipeline serving Chemeketa mutual water company. That is a concrete local example of why infrastructure names need interpretation. It identifies part of a supply system in a dated planning document; it does not identify a current retail account for an unspecified nearby home.
Ask the seller for a recent bill with private payment details removed, the service agreement and a description of any shared equipment. Match the service address to the APN and locate the meter or delivery point with the supplier’s help. If a mutual organization or another intermediary is involved, obtain its current customer rules. The upstream source, retail supplier and owner of the pipe beyond the delivery point may be different parties.
Separate drinking-water service from other supply claims. A tank shown on a site plan might have a particular approved purpose that does not match the buyer’s proposed use. A connection sufficient for the current household does not itself document capacity for another residence, expanded irrigation or development fire requirements. Ask the supplier and the reviewing agencies to address those uses expressly, with the existing agreement and proposed scope in front of them.
If a well is involved, identify the well before ordering tests
Valley Water’s Well Information App guidance cautions that mapped locations are approximate and its records may omit older wells. An apparent absence on the map therefore cannot prove there is no well on the property. Nor can a dot near a boundary establish that the seller owns the well, the site is correctly surveyed or a neighbor has no interest in the supply.
Match the actual equipment to the well identifier, completion records and any shared-use documents. A driller’s historical completion report can describe construction; a current performance assessment addresses a different question. Request identification of the pump, controls, storage and treatment equipment where present. The buyer needs to know which parts belong to the property and which depend on access or agreements outside it.
The County’s water-clearance page describes Environmental Health’s role in well-site review and drinking-water clearance. For work requiring that process, a conditional letter and completed final signoff are different stages. Ask for both where applicable. No new-well application, water-clearance determination or parcel-specific Valley Water search was completed for this draft; the current pages identify the evidence route rather than certify a particular supply.
Have the qualified water professional and laboratory define sampling and performance questions for the identified source. Record where the sample was taken, whether treatment was operating and the test date. One favorable result should not be stretched into a guarantee of all future water quality or seasonal yield. If the buyer intends a different occupancy pattern, the review should address that proposed demand rather than merely repeating how the seller used the home.
Ask for the installed wastewater record
Santa Clara County Environmental Health provides a specific as-built request route. Its explanation distinguishes an approved design from the installed configuration, including changes documented after installation. That makes the as-built a practical starting point for identifying the tank and disposal area. It is still a historical installation record, not a current performance evaluation or assurance that later changes were approved.
The request instructions call for the property address, APN and requester contact information. Gather those identifiers before seeking the record, then compare any returned drawing with the house, access route and other improvements. No request has been submitted on behalf of a private owner for this article. A sample drawing published by the County must never be relabeled as the system at a Holy City home.
The County’s current OWTS program page describes site evaluation, design review, permits and installation inspections. Its FAQ also distinguishes conventional systems from alternative treatment. Record the actual system type rather than deciding from the parcel’s rural appearance. A seller’s pumping invoice can add maintenance history, but it does not replace the design, installed layout or a qualified evaluation of present operation.
Build a packet that exposes mismatches
This packet separates the public evidence actually found from the private records needed to finish an investigation. It is designed to prevent one reassuring document from answering several questions it was never intended to address. Keep the original document and its date beside each conclusion, particularly when a contractor’s report, a County approval and a seller’s statement describe different parts of the system.
| Packet tab | Local evidence available | Property evidence to add | Mismatch to resolve |
|---|---|---|---|
| Supply chain | 2015 Mountain System Master Plan names Holy City regulator and Chemeketa supply relationship | Current supplier agreement, service address and delivery point | Upstream facility mistaken for direct retail service |
| Well identity, if applicable | Valley Water warns that map locations are approximate and historical records incomplete | Well identifier, completion report, ownership and offsite rights | Nearby mapped well mistaken for seller-owned supply |
| Water clearance | County water program explains conditional clearance and final signoff | Applicable letter, completed conditions and current specialist testing | Conditional approval treated as completed compliance |
| Installed wastewater system | County as-built request page specifies address and APN | Returned as-built, installation/repair permits and current evaluation | Approved design or pumping receipt treated as proof of all installed work |
| Proposed change | County OWTS gateway separates new development, additions and modifications | Agency response for the actual new scope | Existing household use treated as approval for extra demand |
Investigate the space around the system
A buyer planning a garage, pool, driveway change or second dwelling needs the infrastructure locations on the same site plan as the proposal. An apparently unused portion of land may have an essential wastewater function or be needed for future repair. Asking the designer to examine the systems together can reveal a conflict before a preferred improvement location becomes part of the purchase assumptions.
For new development, the County’s feasibility instructions describe site assessment, soil analysis, percolation testing and an approved water supply before the design stage is finished. Those are distinct tasks, not interchangeable reports. A favorable statement about one should not be summarized as blanket buildability. The scope and current applicability need confirmation for the actual site and project, especially where the supporting material was prepared for a different layout.
Keep maintenance access visible as well. Locate how a service vehicle would reach the tank or water equipment and whether that route uses someone else’s land. A system may be physically on the parcel while part of its practical servicing depends on a recorded right or coordinated access. The water, wastewater and road files should cross-reference those shared dependencies without assuming that one easement covers every purpose.
Also distinguish a seller’s ability to arrange a service visit from the buyer’s right to rely on its report. Confirm the evaluator’s assignment, access, documents reviewed and limitations before scheduling. A narrowly scoped maintenance visit can be useful evidence without answering a broader purchase question. Ask for unresolved observations to be described plainly, with the next investigation identified rather than hidden in a general satisfactory summary.
Close the file with a defined decision
Before relying on the infrastructure description, write a short conclusion for each system: identified equipment and supplier, documents obtained, current inspection scope and unanswered questions. Separate the existing use from any planned expansion. An unresolved capacity question can affect the purchase decision even when the present home appears to operate normally. A missing record should lead to a targeted follow-up rather than an invented explanation for its absence.
Use the Santa Clara County guide for broader location context and the buying process to organize professional review and timing. A complete Holy City packet will contain the actual residence’s evidence, not merely these public gateways. Until that evidence exists, describe the system and its capacity as unverified wherever the purchase depends on them.
