Design and Planning for Landfill Gas Collection Systems

Design and Planning for Landfill Gas Collection Systems

Most landfill gas design engineers are accustomed to preparing design drawings to incorporate the installation of a gas system into an existing landfill that has been accepting waste for many years. The landfill may require a gas system per the New Source Performance Standard (NSPS) regulations or may be adding

Working Hard for the Money

Working Hard for the Money

It’s not cheap to run a landfill. The costs vary by location, but estimates by the Environmental Protection Agency and various state agencies range from $300,000 to $800,000 per acre for the application, construction, and design and engineering, with as much as $100,000 per acre for overhead and quality control—costs

Post-Fire Erosion Control Methods

Post-Fire Erosion Control Methods

In total, the North Bay fires of 2017 burned about 40,000 acres. The southern California fires were even larger, totaling 1 million acres. The fires burned a wide variety of landscapes, including whole neighborhoods in flat, urbanized areas. Unlike rural areas, these areas are served by urban infrastructure, including storm

PRECON PRODUCTS
The SP360 is Precon’s patented, unique low impact development (LID) retention best management practices (BMP) for stormwater management. It is designed to reduce the potential for downstream flooding, recharge groundwater basins where feasible, and reduce the likelihood of combined sewer overflows (CSOs). The SP360 provides the engineer with

Meaningful Dry-Weather Flow Reductions

Meaningful Dry-Weather Flow Reductions

Dry-weather runoff, or non-stormwater discharge, is flow that enters the municipal separate storm sewer system (MS4) from a combination of activities including lawn watering, over-irrigation, car washing, illegal discharges, and groundwater seepage. These flows, often called “urban drool,” pose an environmental threat due in large part to the trash, sediment,

Natural Stream Channel Restoration

Natural Stream Channel Restoration

EPA protects water quality by regulating municipal separate storm sewer systems (MS4s) to reduce the pollutants that stormwater runoff carries into storm sewers. Nonpoint source pollutants from impervious surfaces such as oil, grease (hydrocarbons), heavy metals from vehicles and atmospheric deposition, fertilizers, pesticides, and sediments are commonly picked up by

River Vision: Denver’s South Platte Communities Transformed

Collaborative construction delivery models such as construction manager/general contractor (CM/GC) with preconstruction services are increasingly proving beneficial to owners and contractors. City and County of Denver’s River Vision is a stunning example of how these methods are providing increased value.
