cleaning grit out of the pump tank

[mallenk]

I recently received a letter from the local minicipality saying that we are dumping too much grit and debris into their system. Since we went from an old diaphram truck to a vacuum truck I am sure that we are picking up more than we want to. We have tried to keep the pump tank clean but with this winter weather we have not been able to wash outside and we are not set up to do so inside. I would like to know what others are doing to prevent this. This is a local dump site and I dont want to lose priviliges. Thanks.:(

Our treatment plants allow us to clean the inside of the tanks at their facilities. You could slide a plastic tub or trough under the rear manway and scrape the grit out into that. Then of course you'll have to dispose of the grit. I'd probably dumpster it.
