Opportunity
Residuals from water treatment, also known as hydrosolids, “alum sludge,” or “ferric sludge,” can be managed in various ways. Aqua Pennsylvania set an aggressive schedule for designing a new residuals treatment facility to replace an existing system that was limited and inefficient.
Solution
Mott MacDonald used a modified design-build delivery method and building information modeling (BIM) to design and prepare plans and specifications for the Crum Creek Residuals Treatment Facility. The facility dewaters residuals mechanically, using belt filter press technology.
We also supplied complete construction phase administration and inspection services for the facility, assisted with startup and testing, and prepared an operations and maintenance manual and record
plans for the completed work.
Outcome
The design, permitting, construction, and facility commissioning were completed in approximately 11 months.
