Managed aquifer recharge (MAR) has become an increasingly important strategy for replenishing aquifers and managing water supplies. Since the 1980s, M&A has developed MAR solutions to integrate imported sources — such as Colorado River water, surface water, and treated effluent — into water resource portfolios. Working in conjunction with engineering partners, we offer the full range of services for designing new recharge facilities; we also have experience assessing existing recharge projects to optimize benefits to the aquifer and minimize costs for operations and maintenance.
M&A has played a key role in over three dozen MAR projects, including the Tonopah Desert Recharge Project — the largest recharge facility in Arizona.
- Conducting hydrogeologic characterization studies to identify the best MAR sites
- Assessing the technical feasibility of recharge at various locations
- Ranking alternative recharge sites based on performance, cost, and other client-defined criteria
- Modeling groundwater flow under various recharge scenarios to predict mounding and water quality impacts
- Working with regulatory staff to negotiate permit requirements
- Developing comprehensive O&M plans for injection wells and surface basins
- Designing recovery wellfields
- Designing monitoring networks and monitoring system performance
