City gets stormwater grant, advertises for wastewater treatment plant system

ARLINGTON The city of Arlingtons Utilities Department is moving forward with two programs that Utilities Manager Jim Kelly believes will help the city become a better steward of the environment.
On Oct. 1, the City Council authorized Mayor Margaret Larson to sign a Department of Ecology stormwater grant agreement. These agreements were written to help local governments design stormwater programs so they could comply with the states new Phase Two municipal stormwater permits, which went into effect earlier this year.
Larson signed the agreement Oct. 4, awarding the city $75,000 with no matching requirements, to help the city implement geographical information system mapping of all its stormwater facilities, as part of its utility comprehensive plan.
The comp plan is 70 percent complete, Kelly said. Once its 90 percent complete, it goes to finance, and when its 95 percent complete, well present it to the public, probably early in January. GIS mapping will tell us what we have and what we have to do to maintain it.
Utilities also received authorization from the Council
Oct. 1 to request qualifications and proposals for the procurement of the wastewater treatment plant membrane bio-reactor.
The bio-reactor is a critical part and by maintaining control through prepurchasing, it allows us to select a supplier and design our own package, Kelly said. Phase one is when the city designs the membrane system and phase two is when the general contractor does the installation and startup. Phase three covers the five-year warranty.
The four-week bidding period will start Oct. 12. Kelly touted the membrane bio-reactor as affording a far greater quality of water treatment than more traditional processes.
Were dealing with discharge limits and expanding population growth, Kelly said. What passes through the membrane is effluent of reclaimed water quality, which can be discharged into the river. We can build a stormwater treatment wetland and supplement it with this during dry months.
