Utilities with uncovered finished water reservoirs
face many water quality, security, and regulatory challenges.
These utilities will need to provide covered
storage or treatment to comply with the Long Term 2
Enhanced Surface Water Treatment Rule (LT2ESWTR)
requirements. This article provides an overview of the
history of uncovered reservoirs, identifies drivers for
improving protection of uncovered reservoirs, discusses
options for compliance with the LT2ESWTR, presents
an approach to decision-making regarding compliance,
and presents case studies that demonstrate how utilities
have implemented various compliance alternatives.
A variety of cover and treatment options are
potentially appropriate for LT2ESWTR compliance,
and many evaluation criteria must be considered
when selecting a compliance alternative. It is recommended
that each utility determine, prioritize, and
rank its alternatives based on criteria that are specific
to its regulatory compliance and project goals.
Typical evaluation criteria include regulatory compliance,
water quality effects, site aesthetics, operations
and maintenance requirements, vulnerability/ public
safety, cost, permitting requirements, and design
life. Includes 26 references, tables, figure.
