Irrigation & Drainage

Discussing drainage and irrigation systems are arguably the most vital landscape projects. The most common issue that effects plant health is not pests or disease – it’s water. Too little or too much water can destroy healthy plants and lead to countless other issues for your landscape as well as your home’s foundation.

OSO Landscape is well staffed with irrigation and drainage experts as well as multiple experienced crews. We use only commercial grade materials and our licensed irrigators are certified and able to work for every city, village or municipality.

All drainage work is also checked and supervised to ensure proper drainage and flow to the storm sewers and culverts. All catch basins are laid by licensed drain-laying professionals with great care. Moss landscaping employs licensed irrigators and, when necessary, works in conjunction with an engineering consultant.
