Line B-1 Inlet Structure at Quarry Pond in Oakland
A quarry pond located at the edge of Oakland’s Claremont Country Club holds stormwater runoff that serves as a water supply for the club’ s golf course. In fiscal years 2008 and 2009, the District made improvements to the quarry pond inlet structure that catches stormwater overflow and directs it downstream. The height of the concrete inlet structure was raised and a sluice gate was added so the District can better control the quantity of stormwater released, while ensuring the club has enough water for its greens. By discharging excess water at a rate set by the District, the potential for flooding downstream is reduced. A debris trap was also installed at the pond to allow a continuous flow of water through the inlet structure.
Pump Rehab
Just like “classic” cars that are carefully dismantled, repaired, and cleaned before they are returned to the open road, the enormous pumps that force stormwater at high tide from the streams and channels into the San Francisco Bay also need to be carefully restored—about every 20 years.
The District began a plan in 2000 to restore pumps at the Ettie Street Pump Station in Oakland, south of the I-580 and I-80 freeway interchange. In fiscal year 2007, the District restored Pump No. 3 of the four pumps housed at the station. During the $99,000 rehabilitation process, the pump column, propeller, and bearings were replaced, and the pump was patched and cleaned.
The fourth pump was rehabilitated in fiscal year 2008.
