Wastewater

Since 1989, HWC has provided comprehensive professional engineering services for private and municipal wastewater systems.  HWC’s wastewater system expertise includes all major components of a wastewater system. As examples, we systematically design new treatment plants, offer solutions for the upgrade/rehabilitation of treatment plants, and are familiar with every facet related to conventional gravity sewers, alternative sewer systems (low-pressure grinder pumps and vacuum), lift stations, and associated incidentals. HWC also provides comprehensive professional engineering services related to combined sewer issues, including long term control plans for our clients. Our services range from concept development to planning, design, and construction observation of wastewater system facilities while promoting sustainable solutions.

Equally as important, HWC recognizes the financial constraints associated with wastewater system improvements and provides guidance regarding funding programs and solutions for our clients.  To that end, we maintain excellent working relationships with major municipal financing and bond counsel professionals.
