Landscaping & Design/Back yard slope problem

Question
QUESTION: Back yard slopes towards house but levels at edge of Patio, also above ground swimming pool in back yard. After rains water pools all across the level portion of back yard and patio right up to edge of house. Pool has covered perforated drain all around that drains into side yard, but drainage around it is slow. Side yard on both sides of house and front yard have very slight slope towards street but are basically at same level as flat part of back yard. Need to get standing water out of back yard without drowning the sides and front. HELP??!!

ANSWER: Hello:

Regrade the area at the house if possible.  You do not have enough slope away from the house. To carry the water away there could be several possibilities.  You might want to consider using catch basins (boxes that collect water and drain it away via pipes).

If you are able to regrade the area to a steep enough slope than some type of surface swale or trench drain may work. If the area is permeable a french drain or drywell system may do the job or a permeable area could be used as a "soakaway" (the water simply soaks into the ground.  For all but the soakaway you will of course need a suitable outlet to dump the water.

If you would like to store water than think about installing a cistern under the area that floods. That would collect some or all of the water and provide you with a convenient collection point for water (with suitable treatment) that can be used to fill your pool,water plants,wash vehicles,etc...

QUESTION: My only question at this point is two fold; What type of storage facility is applicable for a yard cistern? and; What type of water treatment is necessary to make runoff water viable for use, especially in a swimming pool??

Answer
Hello:

Typically, sand and charcoal is used to filter the water and then a treatment of chlorine or ultraviolet light is used.


Plastic cisterns may be purchased or one can be built of concrete or masonry.

Awards and Honors
From Civil Engineer: I am very impressed with your work and with the obvious thought you have put into the marketing of your venture. It was especially good to see a print of that job we discussed on the phone. I wish you much luck with the venture as I do with your plans for school. Im darn proud of you buddy. And by the way,when I get my license,maybe you will consider me for a consulting job down the road. I hope to get together with Rick sometime soon and I would really like to show him your stuff if its ok with you. From all these questions you ask I get the feeling that you are genuinely interested and have put alot of thought into the idea and process of landscape architecture and if you could possibly afford the cost I would urge you to take some classes in the areas you are most interested in. The subject is not so simple as it appears,mixing science and engineering with art and a certain amount of religion to create a comfortable and pleasing balance between man and nature. A thoughtful soul like yours can do this but it can be a lifes work getting it right.
