Water Reclamation & Reuse Program / HARRF Improvements

i Jun 5th No Comments by

Started at the HARRF in the Fall of 1998, Phase I Construction is a major rehabilitation of existing facilities and will improve secondary treatment efficiency. Phase II Construction, completed in 2001, adds tertiary treatment capability to create high quality water production for reuse as irrigation on local golf courses, parks, school grounds, green belts, roadway medians, open spaces and industrial use.  Phase III Construction, currently being designed,  will include a replacement administration building and a rebuild of the influent pump station and the primary treatment building.

Hale Avenue Resource Recovery Facility (HARRF) includes roughly 360 miles of pipelines and 14 pumping station which serve as the sanitary collection system backbone to direct this community’s domestic & industrial wastewater to it’s treatment plant, the HARFF.

MFRO Facility Water Quality Data

The MFRO facility will receive HARRF Title 22 recycled water. HARRF has a permitted wastewater treatment capacity of 18 mgd and 9 mgd tertiary capacity. The plant uses conventional activated sludge for secondary treatment and includes the following major processes: influent pump station, bars screens, grit chambers, primary clarifiers; aeration basins, secondary clarifiers; tertiary filters and chorine disinfection. Historical water quality of HARRF recycled water is provided in Table 2-1 attached.

Treated Water Quality Objectives

The Feasibility Study discussed water quality requirements for the City’s agriculture producers with a key focus on avocado production which is one of the most important crops grown in Escondido. The limits of various water quality parameters that can diminish avocado crop productivity are provided in Table 2-2. This information was obtained based on meetings with members of the Escondido Growers of Agriculture Preservation (EGAP) as well as published information in the literature. Based on discussions with EGAP, it is desired to reduce the chloride concentration to 80 mg/L to prevent leaf burn, root rot and the need for excessive flushing however chloride concentrations up to 100 mg/L can be tolerated. It should be noted historical water quality provided by the City shows the average chloride concentration in raw source water supplies varies as follows: Lake Henshaw = 39 mg/L; Dixon Lake = 80 mg/L; and imported water via SDCWA = 81 mg/L. The average chloride concentration of the treated water from EVWTP is 75 mg/L.

Water recycling could cost $258 Million

i Apr 18th No Comments by

On Wednesday, April 16, 2014, in Escondido, the City Council endorsed a plan to spend estimated $258 million over the next 15 years.  This would be on infrastructure that will allow the city to transform its sewage for irrigation use.

It is said that this is one of the best options for the city of Escondido due to a lack of sewer capacity which threatens to halt future commercial and residential developments.  The only other option to increase capacity for the sewage system, would be to widen the 18 mile long pipeline, but this would cost an estimated $403 million to do this.
