    en.wikipedia.org/wiki/Damp_(structural)

    Key to the selection of an appropriate treatment is a correct diagnosis of the types of dampness affecting a building. Details of possible treatments for specific types of dampness are covered in the sections below. The cause of the dampness must first be eliminated, by providing better drainage or fixing leaking pipes.

  3. Sanitary sewer - Wikipedia

    en.wikipedia.org/wiki/Sanitary_sewer

    The decision to build a combined sewer system or two separate systems is mainly based on the need for sewage treatment and the cost of providing treatment during heavy rain events. Many cities with combined sewer systems built their systems prior to installing sewage treatment plants, and have not subsequently replaced those sewer systems. [2]

  4. Sanitary sewer overflow - Wikipedia

    en.wikipedia.org/wiki/Sanitary_sewer_overflow

    The U.S. Environmental Protection Agency (EPA) estimates that at least 23,000 to 75,000 SSO events occur in the United States each year. [1] EPA estimated that upgrading every municipal treatment and collection system to reduce the frequency of overflow events to no more than once every five years would cost about $88 billion as of 2004.

  6. Stormwater - Wikipedia

    en.wikipedia.org/wiki/Stormwater

    In undisturbed areas with natural subsurface drainage, soil and rock fragments choke karst openings thereby being a self-limitation to the growth of openings. [13]: 189–190, 196 The undisturbed karst drainage system becomes balanced with the climate so it can drain the water produced by most storms. However, problems occur when the landscape ...

  7. Rain garden - Wikipedia

    This system proved to be highly cost-effective. Instead of a system of curbs, sidewalks, and gutters, which would have cost nearly $400,000, the planted drainage swales cost $100,000 to install. [6] This was also much more cost effective than building BMP ponds that could handle 2-, 10-, and 100-year storm events. [6]

  8. Stormwater detention vault - Wikipedia

    en.wikipedia.org/wiki/Stormwater_detention_vault

    The outlet is generally a restricted-flow drain from the detention vessel, with a weir for containing detritus. [3] Detention vessels delay water's delivery downstream, and possibly creates a later water level peak post-rainfall. It is important to consider timing of water release and the types of reservoirs feeding a waterway. [7]
