Confirm the TMK, every dwelling and wastewater source, and whether the property has any documented sewer or wastewater approval.
Puna area guide
Puna includes dense subdivisions, rural acreage, private roads, water catchment, newer construction, and older homes with limited records. A useful review starts with the parcel, the buildings that use the wastewater system, and a realistic picture of how equipment can reach the work area.
Confirm the TMK, every dwelling and wastewater source, and whether the property has any documented sewer or wastewater approval.
Road condition, gate width, lava excavation, overhead lines, and room for trucks can affect construction planning and pricing.
Send photos of the road, driveway, gates, buildings, catchment tanks, wells, cesspool area, and open land that may be available.
Many Puna properties are reached by private or subdivision roads. Before requesting construction prices, document the route from the public road to the likely work area. Note narrow turns, low branches, overhead utilities, weak shoulders, locked gates, and places where a truck could turn around.
Access can affect excavation methods, hauling, equipment size, restoration, and the reliability of an installer estimate.
Visible rock at the surface does not tell the full excavation story. Ask proposals to state what rock work is included, how unforeseen excavation will be charged, where removed material can go, and what restoration is included.
A contractor should price the same approved design. Comparing bids before the scope is defined can produce numbers that look different because they include different work.
List every home, studio, rental, kitchen, bathroom, and other source that sends wastewater to the system. Include planned additions or changes in use. Older records may not show the property as it exists today.
Mark which structures are occupied, which plumbing lines are known, and whether more than one cesspool may be present. The engineer can determine what must be verified in the field.
Show catchment tanks, wells, water lines, drainage channels, low spots, and nearby water features. These details help the professional plan measurements and setbacks without guessing from an online map.
Keep the first sketch simple. The goal is to show what is known and identify what still needs to be located.
