DRIVER-WATER-WELL-TREATMENT-CHEMISTRY The main purpose of water well rehabilitation is to restore lost water volume and/or quality. Rehabilitation methods fall into two main categories: chemical or mechanical. Chemical rehabilitation involves discovering the cause(s) of well plugging and adding a chemical solution designed to dissolve the plugging material. Although various chemical formulas are offered by different companies, the basic approach is the same: a successful chemical reaction in the well.

- By 2050 nearly 2.5 billion people are projected to have some degree of hearing loss and at least 700 will require hearing rehabilitation. - Over 1 billion young adults are at risk of permanent, avoidable hearing loss due to unsafe listening practices. - An annual additional investment of less than US$ 1.40 per person is needed to scale up ear and hearing care services globally. - Over a 10-year period, this promises a return of nearly US$ 16 for every US dollar invested.

DRIVER-MATERIALS-INFRASTRUCTURE Municipal pipe market spending makes up 30 percent of overall utility CAPEX for water infrastructure. In part, to address aging pipes, bursts, and other leakage management issues, the pipe market is turning to new materials (plastic) and new technologies (trenchless). More than $234 billion (USD) of capital expenditures (CAPEX) are forecasted over the next decade to address aging municipal water and wastewater pipe network infrastructure, according to Bluefield's forecasts. Precipitated by decades of underinvestment, municipal utilities are under increasing pressure to address deteriorating linear assets at a faster pace. Water losses through leaks for U.S. utilities average 15 percent annually, with some cities, towns, and communities losing more than half of all water pumped and treated for distribution to customers. As a result, rehabilitation of existing pipes is the fastest growing spend category, increasing annually from $253 million in 2019 to $576 million by 2028. Network expansions, particularly in high population growth across the sunbelt states (e.g. Texas and Arizona), will drive the lion's share of spending on new build.
