Here you have some basic water main extension drawings I did in 2000 and 2001.

A 3D drawing I did of a water well house in 1997. Nothing special except it was done in AutoCAD DOS on a lowly 486 computer.

This is a render and preliminary floor plan of one of my favorite proposed water storage and plant designs for a hurricane prone area. The plant was all originally my design from scratch to finished rendering. Done in Google Sketchup.
