Please first read Step 3: Diagram your Drainage System
In Step 4 you will find information on:
• How to evaluate your drainage system design
• Complete French drain and Drywell installation
• Installing plastic pipe and drain tile
Results from the Partial Drainage System – Step 4
In Step 3 – How to Diagram and Layout a Drainage System – we planned a complete
drainage system and decided which portion of it to install first. Trying a partial drainage
system installation first is part of the goal of eliminating the water drainage issues with
the least cost and effort.
Here is the diagram of the portion we decide to install first....
Here is the result of our first step. The next few rainstorms showed that the partial
system in the side yard has eliminated the previous drainage problems – this area can
now be considered complete.
The front yard is a different story; correcting the front foundation ground slope moved
the previous Soggy Lawn Swamp forward enough that it connected up with a smaller
swamp area. This is a partial success in that it moved the water away from the
foundation. There was another partial success from the independent drywells in that
one succeeded in eliminating a soggy lawn spot while the other two appear to at least
partially draining the areas they reside in. The fact that both Lake Downspout issues
and the big Soggy Lawn Swamp and the Rainy River still occur point to the need for a
complete drainage system to be installed in the front yard to handle the new water
collection pattern.
This is the final drainage system diagram. Note that the pipes draining the
downspout problems are solid pipe to move water far from the foundation before
allowing it to soak into the French drain. Also click to see the explanation of the reason
for the mixed 90 and 45 degree fittings in the drain pipe system. If you look close at the
picture you will see a very short 45 degree stub between the 2 and the 3, this is
installed just in case you should later need to run a short length of French drain out to
the lone drywell near the edge of the property.
