IWS has completed the turn-key construction, start-up, and O&M prove out for a new retail complex’s wastewater treatment system in California. The treatment system was notable for the large concrete basin, which required over 900 cubic yards of concrete to construct. The treatment system was a pre-engineered packaged treatment system which included fine screens, pumps, blowers, and a biosolids management system consisting of a pump, blower, and aerators. The project was designed to service up to 20,000 GPD of wastewater. Treated water was dispersed in 20 ft deep, 6’ diameter seepage pits that were installed as part of the IWS project scope. […]

As the leading design-builder and contractor in the onsite wastewater industry, IWS prides itself on helping clients value engineer their treatment system to meet their financial and regulatory project requirements. IWS welcomes the opportunity to meet with you and better understand your project needs and objectives. IWS can team with your engineer or provide direct […]

Total Nitrogen Limits are now routinely included in the discharge requirements for projects throughout the United States. Each state and local jurisdiction has varying requirements, but the default Total Nitrogen (TN) limit in many areas is the US EPA drinking water standard of 10 mg/liter. Depending upon the treatment technology selected, the standard may or […]

The following are an example of evaluation criteria that IWS utilized for a recent treatment system project: Footprint/Configuration – site limitations? Discharge Levels – regulatory requirements? Sludge Production – how much sludge will be produced and how will it be handled? System Complexity/Operator Requirements – what qualifications will my operator need and how often will […]

Dispelling the common myths in the onsite wastewater business. The IWS team can assist you in value engineering your project – including collection, treatment, dispersal, and overall construction. In addition, IWS can provide a constructability review to make sure what gets designed can be constructed without unexpected additional filed costs to the owner. Over the […]

There are a number of factors that impact the selection of a treatment system for a project. Some factors to consider include: Is the initial capital cost the driver for your project or are you concerned with the operating costs? When we do a 20 year Net Present Value analysis for O&M on projects it […]

IWS was awarded a contract by the Tule River Indian Tribe to complete construction of the Wastewater Treatment Facility at the Tribes property in Porterville, CA. The Tribe in conjunction with US Indian Health Services had a design completed for the overall system.

In addition to the installation of the packaged Ovivo® microBLOX™ MBR, the project included connection to the residential conveyance service line and purchase and installation of a 96” diameter by 28ft deep duplex influent lift station. The lift station conveys influent, via pipeline installed by IWS to a 75,000 GPD package MBR wastewater treatment plant and two 12,000 gallon equalization tanks. […]

IWS recently teamed with Souder, Miller and Associates (SMA) on a Design-Build approach to install an improved wastewater treatment system (WWTS) with the capacity to treat up to 30,000 GPD for the 132 home Tesuque Trailer Village owned and operated by the Pueblo of Tesuque located 10 miles north of Santa Fe, NM. The Design-Build contract with the Pueblo was to permit, design, construct, and start-up the WWTS, which is replacing three undersized and failing septic tanks and leach fields.

The Pueblo of Tesuque is a member of the Eight Northern Pueblos and is from the Tewa speaking ethnic group of Native Americans. One of the most traditional of all the Tewa speaking Pueblos, the Tesuque have maintained their customs and traditions even though they have been in contact with outside cultures throughout much of their history. Archaeologists have determined that the Pueblo existed before 1200 A.D. Tesuque Trailer Village consists of two main areas, the original area developed around 1960 and the new area developed in the mid-1980s. Infrastructure in the older area was in poor condition and water and sewer improvements to replace leaking and deteriorated water and sewer lines were conducted as a separate component of this project by SMA.
