White billowy foam and thick brown foam look alike in a photograph and mean opposite things. Field notes on what we found underneath each one, and the order we work through it.
Concrete and pipework are a solved problem. The design is where the money is decided — and where a few small details separate a plant that holds from one you pay for twice.
The discharge permit is not a receipt for the plant you built. It is a ceiling, and the number that sets it came from you. Field notes on declared flows, uncounted streams, and the receiving water nobody walked.
A Cebu river was upgraded from Class D to Class C and every discharger on it inherited tighter limits overnight, without doing anything. Field notes on why we stopped putting receiving-water classification on the client's list, how we trace where a pipe actually ends, and why a change of class is a design change rather than an operating one.
Open a struggling grease trap in Cebu and the layer on top is often grey, curdled and hard rather than soft and amber. That is not grease any more — it is calcium soap, made by our hard water. It explains why weekly bacteria dosing, skimmers and hot flushing do nothing, and why the fix starts at the tap.
