Consider and take action on a resolution authorizing a professional services agreement with Ardurra Group, Inc. for design, bid, and construction phase services related to the SH 3 BPS Chemical Feed Building & Storage Project (WT2402) in an amount not to exceed $525,000 (Executive Director of Capital Projects)
Background:
Approval of this resolution will authorize a professional services agreement with Ardurra Group, Inc. for design, bid, and construction phase services related to SH 3 BPS Chemical Feed Building & Storage Project (WT2402) in an amount not to exceed $525,000.
The purpose of this project is to design a Sodium Hypochlorite-LAS system to improve disinfectant residuals from the City of Houston SEWPP 42-inch transmission water line and increase chemical storage capacity. In 2014, as a stop gap solution, a trailer-based portable chemical feed system was installed at the SH 3 Booster Pump Station as a cost savings effort to feed as-needed chemicals to boost or sustain disinfectant residual during everyday operations. Since the 2014 installation, water production operations has experienced multiple summer seasons where unusual high demands created the need to boost Chloramine residuals in the ground storage tanks located at SH 3. The existing small system lacks adequate storage and chemical boosting to maintain regulatory compliance, at times. Additionally, current chemical and storage system is not adequate to accommodate the ultimate design capacity of 43.9 MGD at the booster station.
The SH 3 BPS plays a critical role in the City’s potable water distribution system. With the installation of 36-inch transmission line in 2024 to supply adequate water to the east of the City, this SH 3 BPS has become even more a vital component of the City’s overall water source, supplying potable water through the old SH 3’s 42-inch and 39-inch water transmission lines as well as the new 36-inch line. Upgrading the chemical feed system to a permanent...
