Drywell Maintenance Tips

Drywell Maintenance Tips

The Monsoon season is a crucial time for giving dry-wells a quick check-up.

See, without proper maintenance, it’s only a matter of time until your backed-up lawn water becomes a breeding ground for mosquitoes and fungi.

We’d like to help you avoid that scenario.

Drywell Types

While most drywells rely on perforated walls to disperse water, the types of things that clog them up depend upon what you use your drywell for.


  • Septic Drywells – Not to be confused with seepage pits or cesspools, and never to be used for sewage, septic drywells can be used to lessen the load on your septic system by taking care of your graywater, or the relatively clean water that comes from your washing machine, baths, and sinks.


While effective, over time, materials like soap scum and lint can start to build up on the walls of the drywell and begin to plug up the holes.

Investing in a graywater filter and keeping it clean can go a long way in discouraging buildup but, depending on how much graywater your household produces, you may still need to clean the inside of your drywell.


  • Runoff Drywells – If your drywell is solely used to take care of excess water from downspouts, storms and surface runoff, you won’t have to worry about soap scum, but you will have to worry about natural debris.


It’s always a good idea to make sure that the cap of your drywell is free from any brush, dirt or lawn debris, and keeping both your rain gutters and the area around the drywell clean will also help to ensure that less junk is finding its way in.

But, just as with septic drywells, the amount of water your well is expected to handle, as well as its age, can make an internal cleaning a necessity.

Cleaning Your Drywell

Once you’ve cleaned your drywall’s surrounding area, you’ll remove the cap and assess the situation. If standing water is making it hard for you to get to a clog, you should be able to rent a pump at any local home improvement store, but make sure that you have a safe and legal place to divert any water you pump.

Otherwise, simply reach in, remove any debris, scrape/scrub the walls and clear the perforations of gunk.
