The Joseph B. Blake Water Treatment Plant Phase 1B Improvement Project began construction in March 2024 and is scheduled for completion in the summer of 2026. The project includes the construction of a new chemical storage building, an underground utility corridor, and sitewide electrical improvements, including a diesel generator that can be used as a backup power supply for much of the plant.

These improvement projects are an important part of Highlands Ranch Water’s long-term investment in maintaining safe, reliable drinking water for our community today and in the future.

Phase 1B updates

As of January 2026

Work is continuing at the Joseph B. Blake Water Treatment Plant to improve how we treat and deliver water to our community. Crews are testing new systems in the chemical building, along with equipment that helps keep treatment systems running properly.

Several behind-the-scenes improvements are now complete, including installing a new fiber optic line that connects the water and wastewater treatment plants. A short, planned shutdown of the water treatment plant began mid-January and will continue into late February 2026 to complete final electrical connections. This work helps ensure the long-term reliability of the facility. Phase 1B construction is expected to be substantially complete by March 2026.

Phase 2 Improvement Project

Planning is moving forward for the next phase of improvements at the water treatment plant, with Carollo Engineers, Inc. selected to design Phase 2 and construction scheduled to begin in the second quarter of 2027.
