A dry well construction is not tedious; you need to know some basics to construct one, and you can have one for your own home. If you read the techniques here, your work will be smooth and fast. Install a dry well in the exact manner, and you will have appreciable drainage reservoir for the long run.
There are tons of places in this world, where state environmental departments and county departments forbid draining water (either domestic or rain) into the sewers and streets without an appropriate arrangement.
Therefore, people residing in such authoritative stricken places have to find a drainage solution for yards and homes to get rid of the water soaking their lawns or houses at such disastrous times.
Hence, somewhere down the line, a dry well construction comes handy. It is a pit that collects all the water from surrounding areas of your residence and slowly percolates that water into the soil. For doing this, underground pipes are installed at a considerable distance from the house.


Required Materials

➤ Post hole digger and shovel
➤ PVC piping: perforated and solid
➤ Spirit level
➤ 50 ft. tape measure
➤ Landscape fabric
➤ Fitting and adapters for downspout
➤ Dry well concrete: top and shell
➤ Drainage stone
➤ Overflow valve

Method of Installation

Step #1: First of all, choose an appropriate location to set up the dry well. Make sure it is located at a sufficient distance from your house's foundation.
Step #2: When the location is finalized, the next step is to measure is the piping that you are going to need to stretch out in the well. Measure both the PVC and solid perforated piping.
Step #3: Next, dig a trench summing up to 12'' deep from the gutter downspout to the set up location of the well.
Step #4: Using the dry well kit, fit and install the required adapters and fitting equipment right to the end of the downspout. (You can saw off any of the pieces if needed).
Step #5: When you begin to install pipes in the well, use solid pipes at the start and then move on to perforated pipes which are closer to the dry well. Immediately lay the pipes into the trench.
Step #6: Use a slope pipe, level it conveniently away from the house to about ¼ ''/ ft of piping. The moment the pipes are laid down in the trench, cover it up and pack it down.
Step #7: At the place where the perforated piping is used with the landscape fabric, form a line trench in that area and cover (layer) it with a drainage stone. Once you are done doing that, install the PVC piping.
Step #8: Fold the fabric ends just to conceal the piping which is installed. Keep adding stones to conceal the trench. Continue to pack down the materials which are added to the trench neatly.
Step #9: Next step is to dig a hole for the well. For doing that use a post-hole digger, or any type of comfortable shovel which is easy to use in the time of action. Make sure you gather these tools around by looking at the size of the dry well first. Line the well with landscape fabric and swarm in 3''-6'' of drainage stone neatly and smoothly.
Step #10: Lay down the concrete shell in the well and attach all the drainage pipes to the newly formed shell. This should extend 6'' deep into the well. Once the piping is placed, fill the surroundings of the shell with more drainage stone. Finally, bond the top of the shell to cover the constructed well.
Now, install the overflow valve by reading the manufacturer's instructions very carefully. Gently wrap the landscaping fabric over the top of the dry well installation and cover it with dirt. Tamp the dirt neatly.
If you are confident enough, then this job can be carried out single-handedly too, without needing any external professional assistance. But most of the time, it is advisable to take professional assistance as it may help you decide the measurements on an accurate scale. Moreover, professionals can suggest a proper design for the construction activity.
