Water treatment systems help improve raw water quality for defined applications. Treatment processes may include screening, sedimentation, filtration, disinfection, softening, and other treatment stages selected according to source-water quality and intended use.

For projects generating industrial or process wastewater, effluent treatment requirements may involve preliminary treatment, pH adjustment, chemical treatment, biological processes, filtration, and sludge management. Treatment methods must be selected based on wastewater characteristics and applicable discharge or reuse standards.

Treated water may require disinfection and additional treatment before use. Subject to water quality and the approved design, reuse applications may include toilet flushing, landscaping, gardening, or other non-potable uses. Potable use requires treatment specifically designed and validated for drinking-water standards.

Project-defined activities may include installation inspections, leak checks, pump testing, equipment operation checks, instrument verification, process start-up support, water sampling, and commissioning documentation. Treatment performance should be assessed against the approved design criteria and applicable standards.
