Case Study: Water Quality Retrofit and Retaining Wall Remediation

Thu, Feb 09, 2012

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.

The Evolution of Stormwater Quality Control

Thu, Feb 09, 2012

Zach Kent is a stormwater engineer for Modular Wetlands in Oceanside, California. We learned about Modular Wetlands’ urban wetland unit in our case study, “Water Quality Retrofit and Retaining Wall Remediation.” We've partnered with Kent to provide a perspective on some dynamics within the stormwater management industry over the last decade, including new processes and technologies designed to meet higher regulatory standards.

Case Study: Water Supply Infrastructure

Thu, Feb 09, 2012

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.

Case Study: Wastewater Infrastructure

Thu, Feb 09, 2012

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.

Low-Flow Plumbing Fixtures: Are They a Good Return on Investment?

Thu, Feb 09, 2012

Information on low-flow plumbing fixtures abounds, and low-flow and waterless urinals are now in widespread use. Flush volume for toilets has evolved to 1.6 gallons per flush, or less than half of the 1980s' standard of 3.5 gallons. The fact that low-flow fixtures can save money in utility costs is clear and easy to calculate with a review of a water bill and an estimate of each fixture’s cycles per month. An enticing payback period for a new fixture purchase can be calculated based on water use alone. However, some facility managers argue that the utility savings offered by these plumbing fixtures are not matched by the unforeseen maintenance and repair costs that they generate. The question of whether low-flow plumbing fixtures offer a good return on investment (ROI) arises.

Toronto's Deep Lake Water Cooling System

Thu, Oct 27, 2011

Downtown Toronto takes advantage of Lake Ontario's constant lake bottom temperature to operate a heat exchange system.

Toronto’s Deep Lake Water Cooling system offers the city’s downtown property owners a compelling alternative to their buildings’ air conditioning requirements. Instead of installing separate chilled water generators within their buildings, many are taking advantage of the Deep Lake Water Cooling system, operated by Enwave Energy Corporation. The Deep Lake Water Cooling system offers substantial cost savings if building operators forego a standard chiller plant and instead install heat exchangers to interface with it. We’ll overview the functional parts of the Deep Lake Water Cooling system, which has been in service since 2004: the Lake Ontario intake pipes, the Island Filtration Plant, Enwave’s Energy Transfer Station (ETS), and the closed-loop Deep Lake Water Cooling chilled water circuit that individual buildings can access with new heat exchangers.

Managing Facilities and Real Estate

Thu, Aug 18, 2011

Michel Theriault understands the working environment that facility managers face daily – the technical challenges and opportunities within their facility management organizations and additionally the relationships and business dynamic beyond the facilities management staff. Many facility management resources offer the latest technical insights and maintenance strategies, but Theriault’s book takes on facilities management business aspects not often addressed in this field. Managing Facilities & Real Estate clearly stands out in this regard. It offers rare and valuable business advice for facility managers using practical and easy-to-read terminology and graphics.

Successive Alkalinity-Producing Systems (SAPS)

Fri, Dec 23, 2011

A challenge of mining operations and any project that disturbs large volumes of earth below grade is the potential to generate contaminated water runoff at the surface known as acid mine drainage (AMD). Precious metal and coal mine shafts traditionally require excavation below the water table, exposing metal sulfides in the disturbed earth and waste soils to the atmosphere and water. Similar exposure can occur during major highway construction projects. Stormwater runoff and water discharged from dewatering pumps related to these construction activities can be very low in pH (acidic) and can contain harmful metal ions. Eric McCleary of Greenhorne & O’Mara helped develop the successive alkalinity-producing system (SAPS) process to treat this AMD water and shares insights regarding this innovative technology with the Buildipedia audience.

Return on Investment (ROI): T5 Lighting Adapter Retrofits Offer Savings

Thu, Jun 09, 2011

When considering a florescent lighting system upgrade, many facilities managers are retrofitting by placing adapters in existing lighting fixtures. Lighting retrofit kits with adapters have advantages over more comprehensive lighting system component upgrades – they reuse existing lamp fixtures, provide new self-contained electronic lamp ballasts, and offer reduced installation, maintenance, and operating costs. We’ll take a look at the basic ideas involved in a T5 lighting retrofit project, including a return on investment (ROI) case study that calculates payback as less than five years.

Is Your Construction Project in Good Shape?: 10,500 Questions to Ask

Thu, Aug 25, 2011

Originally developed as a checklist to be used during development and execution of Engineering, Procurement, and Construction contracts (EPC’s), Mike McMahon’s EPC Checklist has broad application -- whether you are developing project punch list items, ensuring separate tasks are scheduled by engineers, vendors, contractors and project managers, or providing construction inspectors a list of work items to validate in the field, this comprehensive list of questions will add value to your project.  Sometimes construction project solutions and positive outcomes are all about knowing the right questions to ask -- here are 10,500 of them, organized by 176 subjects of construction work type.
