Water Reuse

Efficient Water Reuse System

OSCAR Onsite offers an excellent way to irrigate and fertilize crops through subsurface drip dispersal via a highly efficient water reuse system. Wastewater and water reuse/reclamation contractors in Washington and Idaho regularly depend on our company for wastewater treatment solutions. As a conscientious industry leader, we’re dedicated to offering products and methods of wastewater management that protect our environment and ensure the future of our water supply.

Exploring Additional Sources of Water

The increasing numbers of people living in higher concentrations along coastal areas has society continually searching for additional sources of water for ever-growing demand. But concerns regarding groundwater depletion, minimum stream flow for fisheries, and other environmental issues often prevents additional construction of dams and wells.

In order to avoid water rationing and limits on development, lawmakers and government agencies have passed forward-thinking laws and regulations to facilitate innovative technological advances in the treatment of wastewater. The resulting advances in treatment technology now allow some states to be able to re-define highly treated reclaimed water a new water source! In these states, gone are the days when the concern was how to get rid of wastewater. That water can now be turned into a commercially valuable resource to be reused or sold to end users via a water reuse system.

Uses of Reclaimed/Reuse Water

Wastewater pushed through a sophisticated water reuse system can be used for ground water recharge, stream flow augmentation, surface and sub-surface irrigation, cooling towers, boilers, toilet flushing and more!

The definition of  reclaimed water varies from state to state, but generally includes the same constituent levels for Class A reclaimed water: biological oxidation demand, total suspended solids (10/10 mg/l), total coliform (2 colonies MPN / 100 ml), turbidity (2.2 NTU) and in some cases, total nitrogen (<10 mg/l). There are two recognized generic processes to achieve Class A reclaimed water:

  1. Oxidation, coagulation, filtration, and disinfection.
  2. Oxidation, membrane filtration, and disinfection.
  3. Other methods that meet the same standards as those listed above

Treatment Utilization

OSCAR Onsite’s Water Reuse System

OSCAR Onsite has developed a process train that utilizes three of the four steps listed in Method 1 above: oxidation, filtration (physical and biological), and disinfection. Our water reuse system meets the process requirements in the following way:

  • Oxidation:LOWeFLOW™ treatment system (10/10 mg/l BOD5 and TSS)
  • Filtration:Lowridge polishing filter Called OSCAR (turbidity < 2 NTU, TC <200 MPN / 100 ml).
  • Disinfection: Ultra violet light (TC <1 MPN / 100ml).

Treatment Utilization

Another option to take advantage of previously used water is to incorporate into drainfield design areas suitable for growing above ground food crops. Called ‘treatment utilization’, the concept is to plant vegetation in and around the area used for treated wastewater dispersal. The permits required are simple septic (or onsite sewage treatment) systems, and installation permits. After the systems are installed and approved, strategic planting of fruit trees, tomatoes, herbs, cucumbers, beans and other above-ground food crops are implemented to take advantage of the water and nutrients discharged into the soil. The best method of dispersal for ‘treatment utilization’ is subsurface drip technology via the OSCAR System, which is explained with the rest of our wastewater treatment and dispersal products.
