Mike & Dirty Jobs Crew, We rahabilitate wastewater structures. Sewage treatment plant tanks, sewage grinder pump stations, manholes, etc. This gets pretty diry when we clean the poop away and when we water blast with 40,000 psi it's not just dirty but hard. Then after the dirty and hard stuff is done we line these poop tanks/structures with a bright Famingo Pink lining. This would be a great episode with lots of smiles. Visit our website to view the lining product www.spectrashield.com and contact me if you would like videos or pics of the poo we clean. Thank you Gary Mock gmockart@metalink.net
