The Board of Directors has expressed interest in stormwater capture to augment water supplies and aquifer recharge for North Central Orange County. Background: OCSD has been active in stormwater capture for more than a decade with its urban runoff diversion program. This program is approved to accept up to ten million gallons per day of urban runoff, which is technically stormwater. Expressed differently, this ten million gallon per day of flow is equivalent to 18 cubic feet per second. The program was originally begun to improve beach water quality by diverting river water laden with bacteria from reaching recreational beaches. OCSD has limited the flow to dry weather to protect its collection system and treatment plants from having overflows which are spills. OCSD's service area contains several dams to control wet weather stormwater flows. These include Prado Dam, Carbon Canyon Dam, Brea Dam, Fullerton Dam, Villa Park Dam, and Santiago Dam. These Dams are connected to rivers and channels which are designed to flow large volumes of silt laden water in order to protect regions from the damage associated with flooding events. Prado Dam is capable of releasing more than 30,000 cubic feet of water per second, or more than 19 billion gallons per day. The Orange County Water District is primarily responsible for recharging the aquifer in North Central Orange County. It controls more than 1,000 acres of river, ponds and percolation basins in Anaheim and 1,250 acres of surface water storage behind Prado Dam. The dam is controlled by the Army Corps of Engineers to protect from flooding and secondarily to store stormwater to recharge of Orange Counties' aquifer. The water is released at a rate that allows for diversion to the Anaheim recharge ponds and lakes usually less than 100 cubic feet per second. OCSD's systems are not designed to handle wet weather stormwater volumes or content. Wet weather naturally increases flow through OCSD's system caused by inflow and infiltration. Inflow is direct flow into the system generally attributed to illegal connections, leaks through manholes and other openings to standing or flowing surface water. Infiltration is ground water that seeps into the sewer system through pipe and manhole defects. These flows can increase normal dry weather flows by 2.2 times. Recommendation: Orange County Sanitation District must balance its mission to protect public health and to create usable products like potable water. Treatment Plant and collection system capacities are designed around normal system flow patterns. These sewers and plants are completely incapable of dealing with even minor rain event stormwater flows. Sewer pipes are a fraction of the size of storm drains, much less flood channels. Storms flows are not necessary for feeding the GWRS. Normal sewage flows, even in a historic drought, are feeding the system at near capacity. The greater risk to OCSD's mission is the risk to public health that occurs with sewer overflows. Raw sewage in the streets or waterways is a completely unacceptable outcome. Issue Paper Presented By: Rob Thompson Item#8 Stormwater capture is the purview of Orange County Water District, OC Flood, and the U.S. Army Corps of Engineers. They have the necessary infrastructure and available land. OCSD should continue to accept dry weather urban runoff to support water reuse and protect beach water quality. Issue Paper Presented By: Nick Arhontes Item#9 Should OCSD change the Level of Service (LOS)for odor complaints? In 1989, OCSD began addressing collection system odor and corrosion concerns chemically by implementing a caustic soda shock-dosing program for some of the trunklines. In 2001, this program evolved to continuous chemical dosing in the collection system for odor control which utilized ferrous chloride, magnesium hydroxide, and calcium nitrate at nine different dosing locations. The program has proven to reduce odor and corrosion in the regional trunk system and suppress odors at the headworks of the treatment plants. It also helps condition the sewage arriving at the treatment plants. In 2007, the Board of Directors adopted the Five-Year Strategic Plan, which set the Level of Service standard at a goal of 34 or less odor complaints attributed to the OCSD collection system. At that time two categories were tracked; Attributed, and Not Attributed. The attributed category captured complaints attributed to OCSD as well as those whose source could not be determined. The complaints were classified by the OCSD responder. In 2009, a third category was created by staff to appropriately document odors of an undetermined source. With the addition of this category, odor complaints attributed to OCSD were reduced significantly. As a result,the goal was reduced in 2014 to 12 complaints or less attributed to OCSD. In 2014, the Odor Control Division revised its Odor Response Procedure to include a follow up investigation as a secondary response for each odor complaint. The objective was to minimize the unknown sources and ultimately better address the root causes of the odors. The complaints were classified by the secondary OCSD responder after the investigation was concluded. Our LOS goal for FY 14/15 was 12 or fewer. Due to the results of the detailed investigations, the number of OCSD attributed complaints has increased. We had 27 validated odor complaints in the collection facilities in FY 14/15 due to various causes. It is recommended that the Level of Service goals be changed to better reflect the current methodology used to investigate. Recommendation: Increase our current level of service from 12 odor complaints to 28. A new goal of 28 or less odor complaints attributed to OCSD would reflect the success of the change in procedures in determining the true source or root cause of the odor complaints. This new LOS could also be achieved within the current budget/sewer fee structure. Staff does not foresee a reduction to the current number of complaints until the plant odor facilities modifications are completed. Any further reductions would also require modifications to Collections' Odor Control Program. Modifications could include items such as additional dosing facilities, additional siphon vents, and repairs to existing siphon vents within the collection system. The Collection Facilities Odor Control Master Plan Update expected in 2017 will help guide the future direction. The new goal of 28 or less odor complaints attributed to OCSD is an appropriate reflection of current Odor Control Program procedures. By continuing to better investigate the root causes of the odors, we can improve strategies for mitigation. The desired outcome may be to eventually reduce the number of attributable odor complaints to zero for those facilities that are a part of the continuous dosing or"sewage conditioning" program.
