When it comes to water and wastewater solutions, the choice is clear.

Improving the quality of our drinking water is much more than a business capability to us; it’s deeply personal. And we’re equally committed to making sure that the wastewater that our businesses and communities generate doesn’t harm the environment.

That’s why Robert B. Our Co. has become a leader in the construction of state-of-the-art water treatment and wastewater facilities across southeastern Massachusetts.

Of course, no matter how qualified and motivated our team is, successfully addressing the issue is bigger than any one company. So we strive to maintain positive, long-standing relationships with design and engineering firms, subcontractors, and vendors.

Knowles Crossing Water Treatment Plant

The busy fishing port of Provincetown, MA, had a water system that dated back to around 1900 — and its two well fields were beginning to produce increased iron and manganese levels that at times exceeded Massachusetts drinking water standards.

With no real alternatives for clean drinking water, the town hired a firm to design a new microfiltration membrane treatment plant.

The new 1.2 MGD facility uses potassium permanganate for raw water preoxidation treatment, followed by membrane filtration for removing iron and manganese precipitates and sodium backwash water is discharged to exterior sand filters for aquifer recharge. A 10,500-foot raw-water transmission main was installed from the South Hallow Well Field to the plant so both well fields could be served by the same plant.

Wastewater Treatment Plant Phase 2 Improvements

There were a lot of updates to be completed within this existing 4.3 MGD wastewater facility — and they would all have to be done without disrupting the daily plant operations and flows.

The job consisted of constructing a new chemical feed building with chemical feed equipment, piping, and storage tanks. It also required constructing a new cast-in-place concrete sludge storage tank with associated piping and equipment.

In addition, the plant required methanol system improvements with new pumping equipment and piping, sludge processing modifications, including new pumps and piping systems, denitrification system improvements, HVAC modifications in multiple plant buildings, electrical modifications throughout the facility, and instrumentation and control modifications in various process systems.
