Description

Sumping of gutter downspouts is a common stormwater management technique to allow the rainwater that falls on a roof to infiltrate and one of the most frequently used BMPs by builders of single homes that aren’t part of a larger subdivision plan. The DEP has provided design guidance in the BMP manual on the sizing of these dry wells, but the material can be difficult to find and is targeted to an engineering audience. The PHRC developed a Builder Brief that summarizes the details on the sizing and construction of downspout sumps for into an easy-to-use guide for homebuilders. This webinar will present design details, sizing explanation and equations, and example calculations of dry wells. Maintenance information that needs to be shared with the homeowner will also be covered.

Learning Objectives

  1. Calculate the necessary dry well volume to manage roof runoff.
  2. Determine if the dry well drains quickly enough to prevent a mosquito problem.
  3. Identify different design options of gravel pit versus pre-fabricated.
  4. Describe maintenance needs to a homeowner.
