On July 31, 1987, the Town received a letter of request from
the San Luis Water and Sanitation District stating that a
serious health threat due to the subsurface water being pumped
into the sewer system lagoons exists in town, The District
has requested the Town take such actions necessary to cease the
pumping immediately, The Town realized that if the homeowners
were forced to cease pumping, the water would fill up in the
basements inundating the electr-icaL ,yater and sewer' systems
and cause the homes to be uninhabitable. This situation
prompted Town officials to declar'e a State of Emergency on
August 4, 1987. The Emergency Declaration was based on a
health and safety issue and requested the Governor's assistance
in alleviating the subsurface water- problem (see Exhibit E),
The Town's request for State Emergency Assistance outlined the
$78,980 SCS Tile Drain Project as a solution to the subsurface
water problem in the hardest hit area of town, The Tile Drain
Project, when completed, would enable the 11Omeownen: in the
northeast area of town to cease pumping into the sewer system,
This action would also enable the District to come into
compliance with the Colorado Heal th Department's recent
orders, The SCS Tile Drain Project could also be used to
facilitate any other areas of Town with subsurface water
pr'oblems to hook up to the system b)' installing laterals (see
Exhibit B),

At present, the Town is awaiting
Governor through the Division of
(DODES) concerning their State of
assistance (see Exhibit G).
