Brief de Design de Logo
Commercial Septics Australia is a new business that consults, designs and installs commercial wastewater treatment systems. (Septic tank systems for commercial buildings in regional areas with no central sewerage treatment plant)
Lilac is a colour palette that is associated with wastewater, so we would like to use this (probably combined with blue - but we are open to ideas).
Systems typically incorporated round tanks and either rows of irrigation pipework, sprinklers or ponds. Anything that alludes to these shapes is positive as too would anything that represents recycling.
I have included a lot of info for context but will ultimately prefer something simple/ clean/ professional with some elements included rather than a busy logo with it all.
