01 / INSIGHT

Connect the project to groundwater checks

Miyakojima’s water department explains that proposed sites and buildings must be checked for their effect on groundwater sources. This assessment and arrangements for receiving a water supply are separate steps. Provide the parcel, use, building scale and pool proposal.

02 / INSIGHT

Plan where water goes afterwards

A pool, laundry, bathrooms and kitchen create different demands. Confirm sewer connection or treatment requirements, capacity and rainwater handling for the particular site and use. A nearby water main does not establish that the planned development can connect at the required capacity.

03 / INSIGHT

Plan equipment replacement

Consider shipping, contractor travel and delivery vehicle access. Record model numbers, repair contacts and alternatives for essential equipment such as pumps. Obtain actual quotations for costs and lead times; do not assume off-island parts arrive immediately.
