Paul,
Yes, I have reviewed the plans. There are a couple of items that need to be included in the plans that are missing.
1) There needs to be a standard trench detail that shows minimum burial depth and that describes the type of soil material
to be used in the pipe zone (within 1 foot of the pipe). For PVC pipe, this is 3/4" minus soil
2) The plans did not outline the pressure testing and disinfection requirements. These can be found in R309-550, the
DDW Administrative Rules for design and construction of water lines.
Having said that, I know your plans said that the construction of the water lines needs to adhere to Parowan City's
construction standards. Since Parowan does not have approved water line standards (details and specifications) that
have been submitted to DDW, we don't know if their standards meet DDW requirements. So, that is why we need those
items above included in the plans so we can be sure they do.
Let me know if you have any questions.
Paul
