In a recent government meeting, officials outlined critical updates and future plans for the city's sanitary sewer, stormwater, and water treatment systems, emphasizing the need for significant infrastructure investments to maintain public health and environmental standards.
The sanitary sewer program, which encompasses 832 miles of pipes and 10 lift stations, is undergoing extensive rehabilitation and reconstruction efforts. Nearly half of the sanitary mains are over 100 years old, with 80% exceeding 80 years. This aging infrastructure is a primary concern, driving the capital program for the surface waters and sewers division. Officials highlighted the importance of removing inflow and infiltration from the sanitary system and aligning improvements with street reconstruction projects.
The stormwater system, consisting of 566 miles of pipes and various pump stations and holding ponds, is also in need of attention. The majority of its infrastructure is at least 50 years old. The city is committed to meeting Clean Water Act regulations and improving water quality through ongoing projects, including flood mitigation efforts and the repair of storm sewer infrastructure.
In terms of drinking water management, the water treatment and distribution division oversees a vast network valued at approximately $2 billion. The city plans to invest $20 million to $30 million annually in capital projects aimed at modernizing treatment facilities and distribution systems. Notably, 69% of the water mains are unlined cast iron pipes installed between 50 and 150 years ago. Despite this, the system has maintained a low rate of water main breaks due to strategic investments in rehabilitation.
Facility upgrades are also on the agenda, with plans to modernize the Fridley campus, which dates back to 1925, and the Columbia Heights campus from 1897. A new water distribution and maintenance facility is also set to replace an outdated structure.
Overall, the meeting underscored the city's commitment to ensuring the reliability and safety of its water and sewer systems, addressing aging infrastructure, and complying with environmental regulations to protect public health and the environment.
