Private Wastewater Treatment Plants

Wastewater Treatment Plants (WWTP) are wastewater treatment plants that are usually large, although tend to be smaller in scale compared to municipal treatment plants. WWTP treat sewage, industrial waste and or agricultural waste from one or a group of commercial/residential entities that are not tied into the municipal sewage system. After the waste has been treated, the effluent will be discharged into a professionally designed disposal system. Some examples are Leach Fields and Injection Wells.  Laulea Engineering has experience in designing new WWTPs, rehabilitating and expanding existing WWTP, Leach Fields and Injection Wells. Laulea Engineering works closely with the licensed contractors and the client to ensure the highest quality construction and compliance.

Individual Wastewater Systems

Similarly, an Individual Waste System (IWS) is a decentralized system that receives and disposes on-site domestic wastewater from one or multiple buildings that are not connected to a centralized wastewater treatment plant. Some IWSs treat wastewater by removing pollutants such as solids, organic matter, nutrients and bacteria using Aerobic Treatment Units (ATU) or Septic Tanks. Not all systems provide equal levels of treatment. Suspended growth aerobic treatment systems provide secondary levels of treatment, for example, while others such as septic tanks only provide primary treatment.

Laulea Engineering has experience in designing both Wastewater Treatment Plants and Individual Wastewater Systems (IWS) through out the Hawaiian islands.

Underground Injection Control (UIC)

The UIC Program regulates the injection of fluids into injection wells and ensures the prevention of any potential ground water contamination.  Nationally, UIC is enforced by the Environmental Protection Agency since its inception in 1974 when Congress passed the Safe Drinking Water Act.  Locally, in Hawaii, the UIC Program is regulated by the State Department of Health (HDOH) Safe Drinking Water Branch, which requires that injection wells fall under specific categories permitted under their UIC Program.  Hawaii Administrative Rules Title 11, Chapter 23 references the conditions governing the location, construction, operation, and monitoring of injection wells so that subsurface injected fluids do not migrate and pollute ground water sources for consumption.  In Hawaii, the sensitivity for the protection of the environment (land and water) is especially elevated thanks to the deep-rooted values instilled in the communities within the state.

The State of Hawaii Department of Health (HDOH) UIC Monitoring Program consists of regularly checking the status and operation of injections wells, performing percolation tests, and producing an annual status report of the wells based on the cumulative data collected over the monitored year.

Laulea Engineering LLC is proud to provide the full package service for ensuring that the injection wells in Hawaii are in proper operation and compliant with the HDOH Safe Drinking Water Branch to keep the environment pristine.  In addition to UIC Monitoring, we are qualified consultants and designers of individual wastewater systems (IWS) with a professional civil engineering license and years of experience statewide.
