Leander City Council approved updates to the city’s wastewater master plan Oct. 3. The updates recommended over 40 projects in the next 20 years, which were projected to cost $266 million, according to the agenda item.

Two of the roughly 43 projects were recommended to be undertaken in the immediate future, and they are projected to cost about $28 million.

Two interceptors, or wastewater pipes that collect and transport water, were recommended for immediate widening, assistant city engineer Sarvesh Dhakal said at the meeting.

The update recommended that 13,020 feet of the Block House Creek interceptor be widened from 21 inches to 24 inches to stop slight flooding from manholes that occur in the area, he said. The more than two-mile project is slated to cost $17.6 million.


Additionally, the new plan recommends 8,170 feet of the Mason Creek interceptor be widened from 15 inches to 24 inches. The project is expected to cost $10.29 million.

According to the planning document, there are three projects slated to be undertaken in the next five years, up to 18 in the next 10 years and 22 in the next 20 years.

Measuring the impact

Leander currently has a wastewater capacity of 8.24 million gallons per day, and the recommendations from the plan update aim to increase that number to 11.67 over the next 20 years, Dhakal said.
