Once that you've decided on a water effect for your landscape and given consideration (design) as to location, size shape to accommodate drainage, proximity to utilities and esthetics (please see previous Sections) it is time to plan the actual construction.

First in order of importance and often times number one in cost is excavation. My advice is to use power tools and equipment when and wherever possible. The costs in blisters, backache, lost time and sleep are much greater than the rental of a power digger, demolition hammer, backhoe or tractor. However, if the basins are small enough and your resolve strong enough, you may find pick axe and shovel work to your liking.

A philosophy of digging methods and attitudes might fill a book itself; suffice it to say that:

1) You're going to divide the world into two parts; the hole/s and not the hole/s. 

In large water features, it's an asset to have a sloping, definitely deeper section... for cleaning, especially for dumping out entirely. 

2) Work from a measured, marked off edge (use chalk or flour).

3) Parties, barbecues are great construction expediters. You would, will be amazed at how many "volunteers" there are to be had for a get together with food and drink.

4) As per item #3 above, get help! The job goes easier and is more fun when friends and family pitch in.

5) Pace yourself. Rome and your feature will not be built in one day. Don't hurt yourself by pushing too hard, too long and fast.

Sometimes, with small basins, places to hard to get back hoes, skip loaders into... it's mano a mano all the way. Here's Matt Tsunoda pushing a shovel.

6) Despite 5, don't stop digging! If you have any doubt as to whether your basin(s) are big, deep enough or the sides steep enough, keep going. When the sides are formed and the bottom laid, you'll lose volume. By not filling all the way to the top, you'll lose volume. By emplacing rocks et al. you'll lose volume. It is easier to dig the system right once then to break it out and do it again.

7) Enjoy yourself. Keep the end result foremost in your mind. You are an artist. 

After pulling out the soil, you'll discover evidence refuting the law of conservation of matter. You have more material then will fit back in the hole! Perhaps you're lucky and can scatter your excavated soil or maybe have available a canyon, your own or neighbors' low spot in need of fill. Maybe this is your big chance to do some mounding and add to your landscapes "hilliness". Whatever way you do it, the worst part of waterscaping is usually excavation. 

It's a good idea to check with your plot plan for drainage, and utility companies before digging. Local waterscape and landscape companies can be helpful in suggesting the best available, most appropriate excavation technologies. If you have to, build it above ground, contract the digging out, use dynamite, just do it; you'll be well on your way to completion.
