Sewage is the number one enemy to the water quality of the Jones Falls. Chronic leaks have caused a severe bacteria problems especially in the lower reaches of the river. Aging sewer lines are located directly next to the streams, allowing gravity to move the sewage from Point A to Point B. The proximity to the streams causes many issues when a line backs up or clogs. Sewage leaks generally originate from the following three causes.
1. Exposed sewer lines: As erosion occurs in our creeks, old sewer lines can become exposed to the elements, creating a dangerous situation. Exposed lines are especially prone to breakage from tree limbs or other debris that flows downstream with floodwater.
2. Wet Water Overflows: Some sewer lines get small cracks from old age or root damage. When we get heavy rainfall, rain will soak into those cracks, causing an overflow in the system. This is the most common cause of sewer overflows.
3. Dry Water Overflows: In drought conditions, clogs can form in sewer lines that can cause a back-up overflow.
