Makeup, blowdown and where the water goes

A tower cools by evaporating water, which means it consumes water continuously and concentrates whatever was dissolved in it. Makeup replaces what evaporates; blowdown dumps some of the concentrated water so the dissolved solids do not keep climbing.

Get that balance wrong in one direction and you waste water and chemicals; wrong in the other and the system scales up, loses efficiency and eventually damages equipment. On water as hard as this region's, the margin is narrower than operators expect, and a controller that has drifted is a common and expensive fault.

Blowdown has to discharge somewhere legitimate. It carries treatment chemicals and concentrated minerals, so it is a sanitary discharge rather than something to send to a storm drain, and on a larger site it may sit inside a discharge permit with limits attached.

The makeup connection is the one that matters most to the building. It draws from the potable supply and it fills a basin of open, warm, treated water, which makes it a high hazard cross connection requiring the appropriate protection, properly installed and tested on schedule.

Metering the makeup line separately is worth doing where it is not already. A tower is often the largest single water user on a site, and without its own meter its consumption is invisible inside the building total, which means a stuck float or a leaking basin can run for months. It also allows an operator to claim any sewer allowance available for water that evaporates rather than reaching the drain, which on a large tower is a real sum.

Scale, treatment and the risk nobody wants to discuss

Water treatment for a tower is a specialism in its own right and it exists for two reasons: keeping the system clean and efficient, and controlling the bacterial risk that comes with warm water and aerosols.

The plumbing contribution is the part that is often neglected: dead legs where water sits and stagnates, a makeup line that has been reconfigured over the years, drains that do not clear the basin properly, and the standing water that collects where somebody once removed a fitting and capped the branch.

Dead legs are worth a specific hunt. Every alteration to a system leaves the possibility of a capped branch holding water that never moves, and those are exactly the places a problem develops quietly. They are also invisible unless somebody walks the pipework with the original drawings and the modifications in hand.

Where a site has a written water management plan, and larger buildings should, the physical items in it are ours to deliver: the sampling points, the drains, the removal of dead legs, and proof that the protection on the makeup line is doing its job.

Seasons, shutdowns and how we work

Towers get shut down and restarted seasonally in a lot of buildings, and both ends of that need doing properly. A tower laid up wet is a problem waiting; laid up dry and then restarted without a proper clean and flush is a different one.

Freeze protection matters here too. A basin, a makeup line and the pipework to it are all outdoors, and a hard freeze with a tower off line splits whatever was left full.

We handle the water side: makeup and its protection, blowdown routing and discharge, basin drainage, dead leg removal, freeze protection and the flushing work at startup. Chemistry belongs to a treatment specialist, and we work alongside one rather than pretending otherwise.

Brownwood, Early, Bangs and Coleman are all inside our area, and sites that cannot lose their cooling get priority when something fails.
