Wastewater Treatment Plant Expansion
Water treatment plant capacity limitations compounded by rapid commercial, industrial and residential development prompted the Town of Brownsburg to undertake a major expansion for its treatment plant. Construction for the plant expansion started in the Fall of 1999 and was completed December 2000.
New commercial, industrial and residential development, compounded by wastewater treatment plant capacity limits, prompted the Town to move forward and construct the expansion that was envisioned in the original design.
During 1996 and 1997, flows to the plant averaged 2.08 mgd, almost 87% of the existing plant's capacity, with extended periods exceeding the design. This project increases the plant capacity from 2.4 mgd to 3.5 mgd (annual average) and from 7.2 mgd to 8.8 mgd (peak hydraulic).
After the expansion, with only three ditches and clarifiers on-line, a peak flow of 9.0 mgd was recorded on October 5th without any operational problems. The additional ditches and clarifiers have provided the plant with much needed capacity to meet current and future needs.
COMMUNITY BENEFITS FROM SRF LOAN
Brownsburg used the State Revolving Fund Loan Program to finance the $6.5 million of capital improvements. The below-market interest rate will save the Town more than $1.8 million throughout the life of the loan.
