Five buildings on the site were designed for residential use and the use of caravans contravened planning law because they were not being used as temporary accommodation.
The court ordered:
• No new or extended tenancies can be signed;
• All existing toilet connections must be disconnected;
• Alternative safe and sanitary portable toilet facilities of at lease one per household must be provided;
• A clay bund must be built downhill of each area where wastewater treatment systems discharge to detain contaminants;
• Areas of wastewater treatment systems for specific dwellings must be fenced off;
• All septic tanks must be emptied and de-sludge activities must be carried out;
• Braines is prohibited from establishing new dwellings on the land.
No toilets or waste water can be used on the site until an engineer has certified compliance, the judge ruled.
The decision said Braines "has no understanding of district plan requirements" and believed that all places there were consented.
Sandy Ormiston, a geotechnical engineer specialising in on-site waste water treatment, found discharge from the septic tanks on the site servicing the dwellings and found significant numbers of E. coli "which pose a significant risk to human health".
The system on the property was not designed to cope with the volumes of waste from the number of dwellings there, Ormiston said.
"In Mr Ormiston's opinion the poorly treated effluent discharges pose an extremely high risk to the ground surface with overland flow to the neighbouring Hibiscus Coast Highway drainage system. He also considers that two of the septic tanks are also at risk of collapsing and thus posing further risks to human health," the decision said.
However, the judge also noted a history of the site's non-compliance with previous enforcement orders and difficulties people encountered when attempting to investigate the site.
