Virginia Wastewater 16 PDH Discount Package 2

This online engineering PDH course provides an overview of key considerations for developing or enhancing management programs for decentralized wastewater treatment systems.

One in every four households in the United States relies on an individual onsite or small cluster system to treat wastewater. In far too many cases, these systems are installed and largely forgotten – until problems arise. On the other hand, EPA concluded in its 1997 Report to Congress that “adequately managed decentralized wastewater systems are a cost-effective and long-term option for meeting public health and water quality goals, particularly in less densely populated areas.”

The key to achieving effective performance of decentralized sewage treatment systems from the simplest “box and rocks” septic tank and drainfield system to the most complex treatment and dispersal units; is an effective management strategy. This strategy must consider several critical elements such as planning, site conditions, risk factors, system design, and operation and maintenance, all of which comprise a management program.

This online engineering PDH course provides information on individual onsite/decentralized treatment technologies or unit processes. Information on typical application, design, construction, operation, maintenance, cost, and pollutant removal effectiveness is provided for most classes of treatment units and their related processes. This information is intended to be used in the preliminary selection of a system of treatment unit processes that can be assembled to achieve predetermined pollutant discharge concentrations or other specific performance requirements.

This 7 PDH online course is applicable to civil, and environmental engineers, as well as design and construction personnel involved with the planning, selection and design of subsurface wastewater infiltration systems.

This online engineering courses is divided in to two parts: The first part discusses sewer systems that use pressure to deliver sewage to a treatment system. The second part discusses small diameter gravity sewers (SDGS) which convey effluent by gravity from a tank to a treatment location. Each part presents an overall description of the relevant topic along with the advantages and disadvantages of each system, design criteria, performance data, operation and maintenance and insights about cost related data.

Alternative wastewater collection systems can be cost effective for homes in areas where traditional collection systems are too expensive to install and operate. Pressure and gravity sewers are used in sparsely populated or suburban areas in which conventional collection systems would be expensive. These systems generally use smaller diameter pipes with a slight slope or follow the surface contour of the land; thereby, reducing excavation and construction costs. These systems convey effluent by gravity from an interceptor tank (or septic tank) to a centralized treatment location or pump station for transfer to another collection system or treatment facility.
