Water Conservation Rebate Program
Deadline for rebates extended to December 31, 2013

Derby residents and business owners can apply for rebates for initiating
High efficiency toiletwater conservation measures. Rebates are available to all Derby water customers, including residential, commercial, owner-occupied, and rentals.

Any device purchased between May 1 and December 31, 2013 is eligible for the program. Applications and supporting documentation are due to the city by February 15, 2014.

Derby’s program is focused on limiting outdoor water use by:
  1. Retrofitting sprinkler systems with water-efficient sprinkler head nozzles to reduce runoff (minimum of 15 required).
  2. Adding smart controllers to irrigation systems to limit watering frequency.
  3. Promoting the use of rain barrels to collect rainwater for watering plants at a later time (one rebate available for up to three barrels).
  4. Installation of High Efficiency (HE) Toilets (1.28 gallons/flush or less).

Rebates will be distributed on a first-come, first-served basis and will be credited to the Derby water customer’s account. Derby customers are not eligible for Wichita's rebate program.

Rebates will be rewarded up to 60 days from the purchase date. There is a maximum of three rebates available per utility account.

Customers can print off a rebate application form or use the online form (link on top left of page). Paper application are also available at City Hall, 611 Mulberry Rd.
