The Wastewater Information System Tool (TWIST)
Overview
The Wastewater Information System Tool (TWIST) is an off-the-shelf, user-friendly management tool that will allow state and local health departments to effectively inventory and manage small wastewater treatment systems in their jurisdictions. It is designed to track information related to homes and facilities served, permits, site evaluations, types of systems, inspections and complaints.
EPA developed TWIST as a comprehensive MIS system with a Microsoft Access database for managing system information. The system accommodates a wide variety of queries, list reports and mapping applications if users provide relevant data. It is designed to help identify and capture important system inventory and service information, and to help standardize management information so data can be easily transferred to other systems. TWIST will help answer key questions for public health and water resource program managers, such as:
- How many systems near drinking water sources have not been maintained?
- Are there systems older than 35 years sited closer than 50 feet from the lake shore?
- Which systems require inspection within the next year?
- How many systems of similar types have malfunctioned over the last three years?
