Civil engineers design them, landscape architects loath them, developers wonder why we need them and municipal engineers often require them - I hate them. Retention and Detention ponds have become the standard for stormwater management on commercial and residential projects throughout most of the US. They were originally intended for flood control and were later incorporated into water quality requirements as well. They serve in their capacity to attenuate peak flows from new development reasonably well, but their usefulness stops there. Here are a few of the reasons that I'm not a fan of detention/retention ponds:
我一直提倡并设计绿色对于数年，现在基础设施和LID解决方案。在那些年里最常见的事情，我听到的是一个“那么，什么是它要花费我？”。假设始终是它要花费更多，他们常常希望它的成本更多。幸运的是，它往往更便宜，而不是更昂贵。这一点尤其与土木工程（雨水基础设施，分级，停车场，景观设计等）的情况下。客户端是，当我告诉他们，这将花费更少的自然怀疑，所以他们的下一条语句通常“真的！？，少了多少？”是。在回答这个问题，我已经发现，“嗯，这取决于”，并不总是靠谱，所以我已经把几的绿色VS传统设计元素。

使用形式旅行者系统提供的显著成本节约桥梁建设项目世界各地。We've partnered with Miguel Barreto from ConstruGomes of Portugal to highlight the key aspects of form traveller systems: how they offer cost advantages over traditional construction systems, in what situations they can best be utilized, and how they function.
“Assessing the conditions of the nation’s public schools remains a difficult process,” says the American Society of Civil Engineers (ASCE) in their 2009 Report Card for America's Infrastructure. The problem leading to this "D" grade seems to be funding. However, part of the problem is that we don’t know how much of a problem we have.
The American Society of Civil Engineers (ASCE) includes Levees on its 2009 Report Card for America's Infrastructure, giving them a D–. The category of "Levees" covers major flood control works. However, what about the water that causes the flooding that levees protect against? Throughout drainage basins comprising thousands of square miles, stormwater runoff makes its way downstream. Obviously some systems convey that stormwater and even control it. ASCE says nothing about these storm sewer systems, but they form a vital part of America's infrastructure.

Buffalo Township’s wastewater treatment plant is located along Buffalo Creek in Pennsylvania, beneath the State Route 28 bridge. This type of wastewater treatment plant is perfect to serve smaller communities. It supports 6,000 people with 3,100 sewer connections to homes and businesses throughout Sarver, Pennsylvania, and the vicinity. It’s an excellent example of an efficient wastewater infrastructure that uses extended aeration to treat raw sewage, without any initial sedimentation.
Located in Freeport, Pennsylvania, about a 30 minute drive north of Pittsburgh, Buffalo Township’s water treatment plant produces over 700,000 gallons of fresh water daily. The plant provides drinking water to over 5,000 residents in Buffalo Township and Freeport Borough. It is also the fresh water supplier for the Municipal Authority of South Buffalo Township. Join Buildipedia for a photo tour of Buffalo Township’s water treatment plant, as we trace the flow of water from the Allegheny River to its distribution throughout the utility.
减少，再利用，再循环。这是环保运动的最简单的口头禅和全国各地的家庭和小程序的指导原则。请问这个原则适用于基础设施，具体的沥青路面？我们已经尽可能少的沥青路面，因为我们可以使用，但是这更多的是一个经济决策。我们回收沥青路面建设新的道路。我们重新用作清洁填充。我们可以用它做什么呢？我们可以用它来收集太阳能？

The City of Takoma Park, Maryland, needed to replace a failing retaining wall that supports a roadway in a small residential development. The Linden Avenue site is directly adjacent to Sligo Creek, which is a tributary of Anacostia Creek, a river undergoing a significant restoration effort. T. E. Scott & Associates, Inc., designed a replacement for the failing retaining wall infrastructure, created a pocket park for the local residents, and provided water quality treatment for the unmanaged watershed. This combination of aesthetic and environmental improvements adds value to the project. We’ll look at some stormwater flow design calculations, a storm water flow splitter, an urban modular wetland unit, a step/plunge pool, and an interesting retaining wall design. Wastewater systems is the sixth topic in our U.S. infrastructure series. The American Society of Civil Engineers (ASCE) assigned the United States’ WASTEWATER infrastructure a grade of “D-” on their 2009 Report Card for America’s Infrastructure. Here we explore the funding issues that effect the aging treatment plants and waterways that make up our nation's wastewater infrastructure. The American Society of Civil Engineers (ASCE) assigned the United States’ Hazardous Waste infrastructure a grade of “D” on their 2009 Report Card for America’s Infrastructure. Why? Too many sites, not enough attention to them, and reduced funding, to name a few. 作为 瓦就此事给你？发电, the American Society of Civil Engineers (ASCE) assigned the United States’ ENERGY infrastructure a grade of “D+” on their 2009 Report Card for America’s Infrastructure. Electricity transmission, which is the second of three installments on energy, covers transmission lines and grid networks, “green” power transmission, and "smart" grids. Electricity distribution will be covered in installment three as we follow the path of electricity from a power generating facility to your home or business. The various blogs I follow send me newsletters, and one article regarding new smart bridge technology caught my attention last Friday. A “smart bridge” is probably better labeled as a talking bridge – one that communicates its status to those who are listening for follow-on interpretation. Baseline measurements of critical strain, deflection, and corrosive conditions can be established with the structure following project completion, then monitored throughout the bridge’s service life.
