Four Corner - Texas Water Development Board

The District is planning to expand their wastewater treatment plant capacity to 0.75
million gallons per day (MGD) which will have surplus treatment capacity available for
350 single family connections. Construction drawings for the expansion have been
completed and the District will be selling bonds to fund the construction. Start of
construction is anticipated in mid-1999. The plant is located on the south side of Keegans
Bayou, just west of Addicks-Clodine Road.
10.2 COST OF SERVICE FROM ADJACENT DISTRICTS
Of the five adjacent districts contacted regarding available water and sanitary sewer
service, North Mission Glen and Kingsbridge MUD were the only two districts with
currently available capacity or the potential for available capacity in the near term.
Purchase of capacity will involve two cost components. The first includes the capital
costs to cover the actual construction of the facilities (direct payment for new
construction or reimbursement for previous construction). The second component will be
the rates charged on a per unit basis to the Four Corners area for water supply and
wastewater treatment. These rates include the cost of operation and maintenance of the
water supply and wastewater treatment facilities in addition to their distribution and
collection systems.
Capital recovery costs for water supply and wastewater treatment were previously
discussed in Section 5.5 but are summarized again in Table 10.2.2. Additionally, the
estimated monthly costs per connection are provided for water and sewer service from
Kingsbridge MUD and sewer service only from North Mission Glen MUD. The costs
presented in this report, are as provided by representatives of each district.
