Municipal infrastructure heats, pumps and stores hard water for decades — and the scale wins slowly unless somebody schedules against it. Chloracid 90 for the works’ dosing lines and exchangers, Dicafas for the remote installations, Limex for the facilities the public actually touches: descaling is a council’s quietest maintenance programme.
Descaling the works’ dosing equipment is chlorination compliance by another name; log it with the water-quality records, not the maintenance pile.
Descale council geysers in the April shoulder — before winter demand, after summer scale — and the complaint season simply doesn’t open.
The lines municipal & water treatment buyers draw from this category most.
Inhibited pickling, descaling and rust-removal compound (liquid) — descaling with an inhibitor so the acid attacks scale, not the metal. Cleans mining membrane filters.

The ones that heat or meter water: geysers in council buildings and hostels (annual Dicafas cycle — the heating-time log is the trigger), works dosing lines and injectors (scale throttles the chlorine dose itself, which is a compliance issue wearing a maintenance costume), pool heat systems where they exist, and the public-facility fittings that Limex keeps presentable monthly. Everything else can be descaled on symptom; these four earn the calendar.
Because a council’s descaling happens at the end of gravel roads: Dicafas rides as inert 25 kg powder, stores through summers in any depot, and becomes working acid only in the bucket at the job — collapsing the transport-hazard chain that a liquid drum drags behind it. Liquid Chloracid 90 stays the right call for circulating jobs at the works where its inhibitor and strength matter. Split the stock by geography, not preference.
A one-page discipline: PPE (gloves, face shield, apron) stored with the acid so the pairing is physical; acid into water, never reverse; absolute separation from every chlorine product the council owns — and a council owns many, from Sypo to pool granules, so the separation is a storage-design decision; neutralise and flush before recommissioning. Two people on every acid job. The page costs nothing and reads like every incident report you will now not write.
Caustic Soda Flakes as the controlled heavy option for organic drain blockages in council buildings and markets — dissolved per label (always flakes into cold water, the mixing heat is real), dosed to the blocked run, flushed after dwell. Soil Soft covers the maintenance dosing that prevents the emergency; caustic is the emergency. Note both keep clear of aluminium fittings, and the market’s grease-heavy drains respond better to prevention than to any rescue.
