How to get rid of a neglected swimming pool?

[Jacob Beg]

Hi All:

I inherited a property with an unused and severely neglected pool. No one has used it for 15 years and it is somewhat of a cesspool at this stage due to years of rain, frogs, infestation etc.

What is the most economical way to get rid of the pool and what sort of costs are associated with this? Do you require a permit for this? Are there any pitfalls to watch out for and are there any structural ramifications. I would love to hear any other suggestions on this. 

Thanks!
