Details Needed Before Drafting

The Chinese article is available, but I cannot prepare a source-controlled English draft yet. Please provide:

• Confirmation that this is the approved Chinese source and its exact revision identifier.
• The approved fact pack and English topic angle.
• A verified English URL for the drainage service page. The article provides only a Chinese-language URL.
• Confirmed contact details for the English call to action.

Once these are confirmed, the draft can keep the article’s focus on photographing localised membrane ponding for an initial assessment without implying overseas site inspection or installation.
