An emerging strategy for urban water infrastructure includes distributed water supply, storm water management, and wastewater treatment to manage water within a utility basin. The use of reclaimed water to offset intra-basin water demand for irrigation can be a key component of such a strategy-landscape irrigation is estimated to account for up to 70% of total potable water demand. Fertigation ( i.e. , irrigation with nutrient-rich water) with reclaimed water is able to offset fertilizer and potable water requirements, which provides an added benefit to end-users. However, research exploring fertigation water production in a decentralized setting is sparse. Two studies to produce high-nitrogen water using a sequencing batch reactor have been described in the literature. While nitrogen concentrations were increased, the changes in treatment resulted in a very low pH in the bioreactor (
