Disconnecting downspouts to a dry well or sump is a way for a single-family home to meet local stormwater ordinances. This Builder Brief will outline the design, sizing, and construction considerations for dry wells. The sizing and construction criteria in this Brief are based on the PA Stormwater BMP Manual (2006) and the PA DEP Model

Dry wells must be located and configured where their construction will not compact the soils below the dry well. Finally, a dry well must have a maintenance plan and, if privately owned, should be protected by easement, deed restriction, ordinance, or other legal measures that prevent its neglect, adverse alteration, and removal.

The primary concern associated with the design of a dry well is its storage capacity, which directly influences its ability to reduce stormwater runoff rates, volumes and pollutant loads. Site planning and design teams should strive to design dry wells that can accommodate the stormwater runoff volume generated by the target runoff reduction rainfall event (e.g., 85th

Formal regulation in 1987 effectively sanctioned the use of dry wells and spurred their construction (see figure). By the end of 2014, ADEQ had registered 51,507 dry wells. Dry wells are used for stormwater control and disposal at virtually every new apartment, hotel, office, and commercial complex developed in the greater Phoenix area in the last three decades, and for

22/08/2018 Dry installed submersible pumps can be mounted either vertically or horizontally, and the form chosen will largely depend on the layout and design of the dry well or wet well. Vertical designs are often preferred for low-lying or underground dry wells because they provide a smaller footprint and can be lifted out directly for maintenance.

The drain rate is a function of the soil permeability rate and the surface area of the dry well through which the water will drain.
